This suddenly started yesterday 3/4/2020.
I have 3 email accounts on my android Outlook app. Outlook.com, Google, my ISP's. The problem only happens with my ISP (comcast.net, IMAP).
Till yesterday night, I can send/retrieve emails from the same server without an issue with Outlook app.
First I noticed Outlook requested to re-enter email password. But it failed. So I deleted account, then added. Failed. I even removed Outlook app and re-installed it. Failed. Google and Outlook account are just fine.
I didn't change anything from my side. I can access Comcast email from Web/Windows 10 mail and even from the same phone using Samsung standard email app.
What was changed and how to solve it? I can use Samsung standard email app but I like Outlook.

Have you tried the Connectivity Tester?
https://testconnectivity.microsoft.com/-> Exchange Server -> IMAP Email.
Thanks for your helpful suggestions. Unfortunately, I still have a problem with downloading my mail after trying smtp port 587 instead of 465 (my password was always simple). My ISP supports smtp on 587 and 465.
First time after creating the imap account I can connect ok, but then OfA hangs downloading the email messages. I eventually get a message asking me to login again, followed by the message saying it's downloading the emails again (in a permanent loop)
I'd have thought these symptoms relate to the incoming imap server configuration, rather than the smtp configuration as reported.
After struggling with this for months, I believe I have finally have workarounds for the issue.
Symptoms included:
Issue #1
While troubleshooting the issue I ran the IMAP Email Connectivity Test from Microsoft as the issue was presenting as a certificate issue.
https://testconnectivity.microsoft.com/ -> Exchange Server -> IMAP Email.
Certificate validation displayed a warning but the actual failure was failing on login with "2 BAD Invalid characters in atom"
Workaround #1: I simplified the password to contain only upper and lower case letters and numbers.
Reference articles:
Issue #2
With the account setup in OfA, I was able to access the mailbox however there were still significant issues and OfA was virtually unusable.
Believing this was likely an issue with an update to the application as these issues started after an application update, I tested the app with the working settings every time the application was updated without any change in the issue.
Finally, I found a thread where someone was having the same/similar issue and they changed the SMTP port to 587.
With SMTP port set to 587, OfA is functioning normally.
Workaround #2: Set SMTP port to 587 not 465.
Conclusion:
Neither of these issues have been resolved, I have simply been able to work around these issues to get OfA to work.
Outlook on PC continues to work with IMAP 993 and SMTP 465 and with a complex password set for the account.
The Blue Mail app has been updated this week. Push notifications seems to work better, still delayed up to one minute though. It is a decent replacement of the Outlook.
thank u...i dont use them...and it still doesnt work...thanks for your thoughts!
