Conversations are a new feature introduced in eM Client 7.0.

This feature is a view option which can show your messages and replies to them in threads that enable you to easily read through the previous conversation on the topic in the given message thread.

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
