Using Outlook for Android in business environments for email and scheduling
Hi,
Microsoft support just suggested a solution which strangely seems to work : simply adding the "000" port number after the server names fixes the bug.
imap.domain.com:000
smtp.domain.com:000
The first connection takes time, then Outlook shows some warnings about connection security, but it works.
I don't think it's a long-term solution, but it can be helpful while waiting for a true software fix.
