Conversations are always created from messages in the given Account folders. The messages are not combined across multiple accounts.  

IMPORTANT: Deleting the conversation from message list when Conversation view is enabled in all views deletes the whole conversation.

You can change your Conversations setting in Menu > View > Conversations section to these options:

1. Conversations in All Views 

2. Conversation in Message detail only

3. Conversations disabled

Similarly, clients don't always handle case sensitivity correctly. For clients that use the local file system as folder storage, the case sensitivity of the file system could play a role. Traditional MBOX or MailDir storage systems will behave as case-sensitive on most Windows systems thus causing issues when the server contains conflicting folder names differing in a letter case.

In eM Client we try to preserve the case of folder names as entered by the user or sent by the server. However, we do not allow two folders with the same name differing by the letter case to be present at the same level in a hierarchy as we have to work with a large variety of servers and interoperate with mailboxes accessed by multiple different clients (including mobile ones). In addition, we allow offline operation where we cannot immediately get feedback from a server on what operations succeeded and which ones didn't. This involves many use cases where interoperability problems could occur if full case sensitivity was allowed. The number of servers and clients properly supporting case-sensitivity folder names was deemed so small that we found supporting it was not worthwhile.

For example, you can move or copy your emails there to make space on the server or to secure them in the event of a server failure. You can also move messages there so you can access them while offline. Just don’t forget that you can also use the ‘Download messages for offline use’ function that downloads the content of selected IMAP folders or of the whole account into the application’s local database.

These folders can be enabled/disabled in Menu > Settings > General > Folders via the 'Show Local Folders' option. The Local Folders will be shown in the left-side folder list under your other account folders.

Note: In eM Client 9 and older this option was in Menu > Settings > General > General.

This feature allows you to check all emails without having to go through each separate account individually. 

You can also pin any of the other folders from your accounts into this section, so the folders you use most often are easily accessible.

These folders can be enabled/disabled in Menu > Settings > General > General via the 'Show Favorite folders' option.

Besides this option, you can always blacklist an email address/domain by clicking the button "Move to Junk" and choosing the option "Move to Junk and blacklist email/domain". This Blacklist is then saved as a Rule in the Rules section.

You can view and manage the Blacklist rule in menu > Settings > Mail > Blacklist & Whitelist. Just select the Blacklist and click the 'Edit' button.
Blacklist is available as a rule in Menu > Rules in eM Client 9 and older.

A new window with all the domains and addresses in your blacklist will pop up and you can add new items or remove any of the email addresses and domains already in it.

If your server does not provide any spam filtering options, we can also recommend using an external Spam filtering program, like MailWasher, Spamihilator or others.

To add variables, right-click the message body while composing a new message and select Insert > Variable. Then you can select a number of variables from a list of available variables.

The content of the variable will be replaced by either data from your computer (such as date and time options) or from your contact's details.

Note: If you use Variables in your message and try to send it to more recipients it will always be sent as Mass Mail (feature available with paid licenses).

You can either use the drop-down menu under the Send button or via Menu > Message > Send later.

 Until the message is sent it is kept in your local Outbox folder.

The Outbox folder can be accessed through Local or Favorite Folders. If neither of these is available, you can enable them in Menu > Settings > General > Folders.

If you want to change or stop the 'delayed' message from being sent, you can edit or remove it from the Outbox.

Note: You can also set a 'default' Send later time for all your messages in Menu > Settings > Mail > Send. 

In eM Client 9 and older the Local and Favorite folders can be enabled in Menu > Settings > General > General.

You can change these shortcuts in Menu > Settings > General > Shortcuts.

You can re-create your rules in Menu > Rules section, though.

a. Press Ctrl and use the mouse scroll button to zoom in/out or

b. Press Ctrl and use either the '+' button to zoom in or '-' to zoom out.

Ctrl + 0 button will reset the zoom to the original size.

Here is a short overview:

    /dblocation PATH

    This parameter will determine which folder will eM Client load the main database from. If the given folder does not exist, eM Client will create the folder and a new, empty database in it. Without this parameter, eM Client will load the database from the currently set default location.

    /localmutex

   Use this parameter when deploying the application in a Remote Desktop Services or Terminal Services environment where accessing global mutexes (short for „mutual exceptions“ in programming) is forbidden – the application will use local ones instead.

    /mailurl RECIPIENT

    Use this parameter to create a new message with a pre-defined email address compliant with RFC 6068.
Example: MailClient.exe /mailurl "mailto:user@example.org?subject=hello&body=bodytext"

    /open PATH

    With this parameter you can open any .eml, .msg, .vcf, or .ics file in eM Client.

    /newmail

    This parameter will open a window to compose a new mail.

    /newcontact

    This parameter will open a window to create a new contact.

    /newevent

    This parameter will open a window to plan an event.

    /newtask

    This parameter will open a window to create a new task.

    /importsettings PATH [-s] [-p PASS]

    This parameter defines a file which contains eM Client settings and its password, which needs to be used to import the data. It needs to be an .XML file and can contain application settings, account configuration, templates, quicktexts, and rules. PATH is the location of the file. The rest of the parameter options are optional. [-s] stands for "silent" and means that the settings will be imported without opening the UI. [-p PASS] is for inserting the password, if there is one protecting the file.
Example: MailClient.exe /importsettings "c:\Temp\settings.xml" -s -p MyPassword

    /activate

    You can easily activate your eM Client using this parameter and activation key.

    This parameter can also be used without the Activation key, but for activation to be possible in this case eM Client needs to have a LastActivationKey entry in its database with a valid Activation key. Usually, the LastActivationKey value is set using the /importsettings parameter.

    /deactivate

    This parameter will deactivate the license in your device. This can be useful when you have a set number of seats on your license and want to quickly free up the space by deactivating the device you no longer plan to use.

Note: This answer applies only to Windows version.

• Local automatic archiving inside the eM Client program and
• Server-side archiving.

Automatic Archiving

eM Client archiving can be found in Menu > Settings > Mail > Automatic Archiving.

The way eM Client archiving works is that the program will create a special set of local folders called 'Archive'. Archive folders will be shown below all your other account folders and Archived messages will be only available in your device. If you will choose to archive messages from a synchronized account (set up with IMAP or EWS protocols) the messages will be removed from the server as well, so you will no longer be able to access them using webmail.

To make the automatic archiving actually work you need to enable it, set how often the Archiving should happen (Archive every X days), set how old the messages should be (Archive messages older than X days) and most importantly, select which accounts/folders you want to perform the Archiving on (Account Preferences).

Click the ‘Archiving Scope’ field for each Account to select which folders should be included.

You can also perform the archiving manually by clicking the 'Perform Archiving' button. This function can be used even without enabling the Automatic archiving in the top checkmark (Enable Automatic Archiving).

Server-side Archiving

For IMAP and EWS accounts the Archive feature will move messages into a single folder called 'Archive', which will be among the other special folders like Inbox, Sent, Drafts, etc.
You can select a message (messages) and use the Archive option via right-click, toolbar button or the default shortcut Ctrl+Shift+A.

The shortcut can be changed in Menu > Settings > General > Shortcuts.

An exception to this is the Gmail Archive. This is a specific function which removes the 'Inbox' label from a message in Inbox, leaving the message accessible in the 'All Mail' folder. You can read about Gmail's native archiving and what it means on Google support. 

Read more in the Documentation: Automatic Archiving

Just right-click any of the left pane items and select the option "Open in New window..".

For IMAP accounts your mail server needs to support these two extensions:

• RFC 7377: IMAP4 Multimailbox SEARCH Extension (https://tools.ietf.org/html/rfc7377)
• RFC 6203: IMAP4 Extension for Fuzzy Search (https://tools.ietf.org/html/rfc6203)

You do not need to enable any setting for server-side search to work, so if it does not seem to behave as expected, check with your server provider or your admin if these extensions are available for your account.

The Attachments view feature is only available with paid licenses.

Read more in the Documentation: Attachments 

To use this feature, you need to have either of these apps installed on your device and login to both the app and login again via eM Client when you first attempt to use it. You can also set up the storage providers in Menu > Settings > Mail > Attachments.

When you attach a file from the Cloud storage folders you will get to decide if you want to insert the file or just the link.  

You can use left and right swipe gestures in the Message list and in Notes.
The actions for both right and left swipe can be set in menu > Settings > General > Swipe.

On Mac you need to enable 'Swipe between pages' in your System Preferences > Trackpad settings to make it work in eM Client.

The Notes are a new left pane section that you can use. In addition to Local Notes (saved in Local folders), you can also synchronize Notes for Exchange, Office365, IceWarp and other CalDAV accounts, if they have a Notes folder on the server.

You can create, edit and delete notes, manage them with folders and tags but also forward them as a message. When you forward a note the Title is used as Subject while the body of the note will be used as the message body.

Please mind that these Note services cannot currently be implemented:

• Google Keep does not allow access from external apps
• Evernote plans to shut down the API access for external apps soon
• iCloud notes - no public API available for access from external apps

Note: Tags have been called Categories in eM Client 7 and all older versions of eM Client.

Read more in the Documentation: About Tags

In the Attachments view (available with paid licenses), you can easily sift through the files directly - you can sort through files based on type, account or the item type it was originally attached to. Read more about the Attachments section on our blog.

Note: These same steps can be used to downgrade from a BETA version to the current eM Client official version - just uninstall the BETA and reinstall current version from the website

Our databases are not backward compatible for older versions and once you upgrade your database to accommodate the new version, you cannot just simply install an older version over it.

If you have a backup of your database from eM Client 9 or older you can skip any export. If not, you will need to export local data before the downgrade to keep them.

For accounts set up with IMAP or EWS protocol this is not an issue, as setting these accounts anew will synchronize messages and folders back from the server.

For POP accounts and any data in Local folders, export them first via Menu > File > Export and once you downgrade, you can import them back via Menu > File > Import.

The steps to downgrade on Windows are to:

• Export any local data you need to keep (menu > File > Export)
• Uninstall eM Client 10
• Either delete the database or rename it
• Install your preferred older version of eM Client (You can find older versions in our Release history)
• Restore from the backup (Menu > File > Restore) or create your accounts anew and import your local data back in (Menu > Accounts, Menu > File > Import)

If you want to just rename your database, the default location is in C:\Users\%username%\AppData\Roaming\eM Client

The steps to downgrade on macOS are to:

• Export any local data you need to keep (File > Export)
• Uninstall eM Client 10
• Either delete the database or rename it
• Install your preferred older version of eM Client (You can find older versions in our Release history)
• Restore from the backup (File > Restore) or create your accounts anew and import your local data back in (eM Client > Add account, File > Import)

If you want to delete or rename your database, the default location is in /Users/User Name/Library/Application Support/eM Client

If you upgraded by accident and aren't sure if you need to downgrade manually, please see the article on this topic - This version of eM Client is newer than what your current license permits.

Next to the 'New rule' button in the Rule window toolbar you can now select from Local rules and your accounts' specific server rules.

When the rules are on the server instead of just in eM Client they will be applied to new messages, even when eM Client isn't running. And if you use eM Client on numerous devices, you don't need to set up or copy the rule to each device separately.

Read our manual on how to use email encryption.

Read more in our blog: PGP: Encrypt & sign emails in a few clicks and in the Documentation: PGP.

If you prefer to view all messages in Plain text, ie. all colors, formatting removed, for easier reading you can do so in Menu > Settings > Mail > Read by checking the option to "Read all messages in Plain text".

Starting with eM Client 8.2, you can also switch the view of a single message on demand and view it in a different format than your default setting.

Simply right-click the message and switch the Format to HTML or Plain text, depending on which one you need to take a look at. You can also find the same setting in Menu > Message > Format.

Go to Menu > View > Conversations and change your setting from "Show Conversations in All Views" to either "Show Conversations in Message details only" or "Disable Conversations.

The feature cannot be used when Conversations are enabled in all views because the arrow is tied to a single, specific message while the full Conversations show the whole thread in the Message list, so it cannot show this icon.

Trying to add a single word will produce the error: Header words must be specified as "Name: Value" pair.

This is because emails have a numerous mail headers which contain specific information - these include From: or Sender: for original sender of the message, Date:, Received: information, etc. If you're creating your rule based on a specific message, you can check the actual headers by right-clicking inside the email > View Mail Header... and find which header name your word is in.

Then just use both the header name and the word in the format Name: Value in the rule, for example From: John will affect all messages where 'John' is part of the visible name or email address of the sender.

For accounts where this data is not available, eM Client uses its internal conversation logic, which relies on message headers. The main factors considered are:

• the same base subject

• sender and recipients

• Message-ID, References, and In-Reply-To

The more complete the context, the more accurate the conversation grouping. Note that during initial synchronization, some messages may lack sufficient information, so conversations may not be grouped optimally until synchronization is complete.
