Outlook app gives network error

Relaks

My company has migrated to Microsoft 365, and I have previously successfully set up the Outlook app on my Pixel 6a running GOS. I downloaded it from Aurora and had no issues logging in with my company login. The app functioned a expected.

But now, after reinstalling the app, it simply won't log in. It shows me the message "Please check your network settings, and try again [2603]".

I've tried clearing the app data, reinstalling it from Aurora, disabling GOS exploit protection for the app, trying on cellular data, residential wifi and company wifi. I've even reinstalled the app via Play Store, in case Outlook added some signature check lately. No luck.

Been trying this for 2-3 weeks. No one in my company is reporting the same issue. Googling solutions haven't given me helpful answers.

I'm installing the app in a separate profile, to avoid it connecting over VPN in my owner profile (which will get me blocked).

Is there anything else I could try?

It's fixed, or at least I got it working. I deleted the secondary profile, again. Then I reset all network options from Android settings > System > Reset. From a new profile I installed Aurora, then installed Outlook. It allowed me to log in, but needed Play Services to complete. So I installed that, and everything seems to work now.

If I had been more methodical, I might be able to surmise what actually made it work. Could've been network settings, could've been Outlook being installed prior to Play Services, even if I wouldn't be able to explain why.

Anyway, posting this here in case someone else has this problem in the future and they stumble upon this post.
