Sent emails are not synced with the server

The problem is caused by a mismatch between the folder names in the Russian version of Outlook and the standard folder names on the server. This causes Outlook to save sent emails not to a folder "Sent", as other mail clients do, but creates a separate folder "Sent" (a similar situation can be observed with folders "Drafts", "Spam" and "Deleted"). A discussion of this problem can be found on the official Microsoft website for URL.

To remedy the situation, you can do the following:

  1. Switch Outlook interface to English.
  2. Reconfigure mailbox connection
  3. Return the Russian interface language.
  4. Check the synchronization of the sent mail.
