Hi. After updating Thunderbird from 68.12.1 directly to 78.5.0, I have trouble receiving messages from the Exchange Server via IMAP (Google and Yahoo work fine). The connection security is SSL/TSL on port 993 with normal password. Even if Thunderbird says "<user@server>: Connected to <server>...", no message is brought from that server. After reinstalling version 68.12.1 and restoring the old profile, the connection works normally with the same settings.

This behavior occurred with version 73.0b1 when the Thunderbird profile format was changed.
