When migrating from the old server, there was a doubling of folders. There is a check mark in the settings of synchronization tasks.
I assume that the reason may be the Russian name of the folders.
Perhaps these are the actions of the mail client, we use microsoft outlook and mozilla thunderbird, but the correct folder with the latest version of emails (current from the old server is not the main folder (for example, sent, drafts, deleted), but the imap folder of the same name.
Is it possible to add them to automap for synchronization?
Is it possible to do automatic merging of folders in all mailboxes based on the name? Several hundred mailboxes have already been moved, now the old server is still the main one and the mailboxes are regularly synchronized.
