Using Outlook for Android in business environments for email and scheduling
We have the same problems on multiple phones with the Outlook app.
However. Our mailserver uses TLS 1.2 and only valid excryption keys are enabled! Even the order is correct.
And my phone (Pixel 4) stopped at Monday last week. My partners phone (iPhone XS) stoppend on Friday connecting to the same IMAP server. The server supports both TLS and SSL on 465 and 587 and 993 IMAP. But the Outlook app does not give the option to input these. The auto config script on the server is not processed. And in the server log I can see that the app is connecting aq Microsoft IP address and not the domain of the mailserver that I entered. Is all encrypted communications of the Outlook app relayed through MS servers? That is what it looks like!
And to my surprise, the ? at top right is SETTINGS that normally should be a wheel in applications (even Windows itslef!)
