Hello, I am having problem with connecting imap inbox folder using Office 365 mail server with user who likes using TB. After adding mailbox to TB it says: The current operation on 'Inbox' did not succeed. The mail server for account [email protected] responded: INBOX doesn't exist. I can't even see the Inbox folder in the menu 'subscribe/folder list. Recently we migrated to Exchange online and after importing old emails by outlook export/import this error showed up and inbox stopped syncing. I believe it must be issue with folder name in O365 which I tried to reset to default but it didn't help. I also tried this https://support.mozilla.org/en-US/questions/1276757 Any idea how to fix this? Thank you in advance.
