Outlook.com connection issues from apps

n5bb · 30 Jan 2024, 02:07 PM

Since around 23 Jan 2024, there have been problems reported with access to outlook.com email accounts via POP, IMAP, and Exchange connections. I noticed this early on 29 Jan 2024 when my Fastmail account first failed to fetch messages from my Outlook account.

Microsoft acknowledges this problem but has not resolved this issue yet. The problem even affects the Outlook email app, Thunderbird, and mobile email apps. They suggest logging into outlook.com on the web, which still works. See:
Outlook and other apps are unable to connect to Outlook.com

I have not had any issues with Claws-Mail. I check three accounts on a daily basis via POP3.

I have noticed occasional timeouts, but a recheck of the account succeeds.

I use outlook.office365.com:995 and smtp.office365.com:587

I do not use OAUTH2.

I think the issue is with imap and not pop.

As I pointed out.in my earlier post (based on the Microsoft support page link), the issue was authentication and affected all types of access, not just IMAP. Microsoft says this issue is now resolved. See:
Microsoft support update

After reading the updated notice from Microsoft today, I did the following:

Logged into my outlook.com account security page
Deleted my old app passwords
Created a new app password for Fastmail Mail Fetch
Changed the Fastmail Outlook.com Mail Fetch password to the new app password

This resolved the issue for me. I seen a test message to my Outlook address and on the next Fastmail Mail Fetch 5 minute cycle the message appeared in my Fastmail account.

You know I remember at some point creating app passwords for each of my accounts. I checked each account settings in Claws Mail. The password in for each account is using the same password (different password each account) to access the accounts web interface. My password manager only shows one password each account. There would be an added app password entry if I was using one. Hm...

I guess if I start having issues, I know what to check for first.
