Using older versions of Outlook for Mac in business environments
I posted a "solution" given to me by Microsoft earlier today.
The "solution" was to delete and then reenter the IMAP account without connecting the account to Microsoft Cloud.
While this resolves the sent folder syncing issue, on further exploration, you lose th ability to create new contacts, add calendar events, and inbox does not synch properly.
In other words, you lose more than you gain.
I am told Microsoft is fully aware and working on it.
**Note:**POP accounts won’t be able to be selected because they do not sync with Microsoft Cloud.
**Note:**Office 365 and Outlook.com accounts won't be able to be selected because they require Microsoft Cloud.
