Hello everyone, 

After upgrading to the latest version, I'm having problems synchronizing a mail via Outlook Exchange Active Sync, whereby it downloads inbox mails very slowly (10 mails per minute), while sent mail is not synchronized.

In the logs I see:

[2023.05.11] 11:27:20.874 [952756908] SYNC KEY MISMATCH (PerformSync) (120003): Device=[20230511.092541.1317] Server=[20230511.092543.1319] User=[xxxxxxx@xxxxxxxxxxxx]

Other similarly configured accounts work. What could be the problem?
