Why is my Outlook/Hotmail/MSN/Live account not synchronizing or really slow?

With the recent changes on Microsoft servers, the IMAP protocol for Outlook/Hotmail/Live/MSN/etc. accounts can be unusable for some external applications at this time.

Please set up your account as Exchange.

  • Download the attached registry file in this article.
  • Run it while eM Client is still closed and confirm the changes it will make.

If you'd like to add the needed registry key manually instead of using our provided file:

  • Run Regedit
  • Go to Computer\HKEY_CURRENT_USER\Software\eM Client
  • Add the DWORD item AllowExchangeOnlineOAuth and set its value to 0
  • Then run eM Client 

To set up the actual account:

  • Go to Menu > Accounts.
  • Click the '+Add account' button.
  • In the New Account window select Mail > Exchange.
  • Use your Microsoft mail address for both the Email and Username fields. 
  • Finish the rest of the setup
  • Delete or disable your previous IMAP setup.

NOTES: Detection of Exchange setup might take longer than usual, but unless an error pops up, let the configuration finish.

If you use 2-factor verification, you might need to create and use an App password for eM Client.

Exchange Web Services protocol will synchronize your Mail, Contacts, and Calendar - you do not need to worry about any data loss because this information is saved on your mail server.
