Hello,

after migrating from POP to IMAP, I cannot access one of my live accounts from thunderbird client.

Both live accounts were changed from POP to IMAP, using imap-mail.outlook.com, IMAP/SSL/993.
One account works fine, for the other one the IMAP server returns:
  • "error 10. Server error. Please try again later."
on IMAP-login. I double-checked the password against the still working POP configuration. I double-
checked settings for any differences to the account working fine with IMAP.

I have Thunderbird logs that show two authentication types failing before TB gives up.

Both accounts can still be accessed via POP or web.

A similar issue was already reported here.
