Outlook for Android no longer grouping contact info...

I just started having an odd issue with all the contacts in the Outlook app on my Android phone...

For contacts that have multiple contact information (ie: a mobile number, house number, and or email address) listed, the app is breaking out the contacts as separate contacts.

Example: If I have James Kirk listed in my phone with a number of 555-111-1701 and an email address as jkirk@fakedomain, he no longer shows up on my phone as James Kirk; instead there are two contacts - one called 555-111-1701 and the other jkirk@fakedomain.

Contacts show up correctly in the Outlook desktop app and on the Outlook website.

If I modify or add contacts on the desktop app, the change is almost immediately reflected on the Outlook website.

Some of the troubleshooting I've done already:

  • Cleared the app cache from the Phone's settings
  • Reset the account from within the app
  • disabled/re-enabled contact synchronization
  • Modified a contact on the desktop app to see if they'd re-sync correctly - had no effect
  • Deleted the account (the contacts disappear when deleted, but come back janky when it's re-added)
  • Uninstalled and re-installed the app
  • Rebooted the phone (for good measure)

uninstalling and re-installing the app seemed to fix the problem initially. Right when i setup the app again all the contacts came back looking correct. It's been several hours since I did this and i just took a look at my contact list and it's all janky again.

It's not just a visual issue on the phone - it's affecting Contact synchronization with the phone's contact app, and everything else on the phone that relies on contacts.

Any idea what's going on and how to fix it for good?

TIA

  • I have exactly the same issue on my OnePlus 10T.

    I have already followed the same steps mentioned by the original poster, including reinstalling the app, checking permissions, enabling contact sync, reviewing battery settings, clearing cache, and verifying the account configuration, but the problem is still there.

    This seems to have started very recently. In my case, I first noticed something was wrong because all my contact photos suddenly disappeared. After that, it became clear that the contacts were no longer being listed properly, and instead the app started showing fragmented contact information rather than the normal contact view.

    At this point, this does not look like an isolated configuration issue. It looks like a real bug affecting Outlook on Android.

    Microsoft needs to acknowledge this problem publicly and provide an estimated date for when a fix will be released.

    An Update on the problem description: It's not just contacts with multiple contact info and the information looks like it's still present, just that Outlook isn't able to use the contact's name...

    IE: i pulled up a contact that's just showing up as a phone number. I edited the contact... all of that person's contact info shows up... name, alternate contact info, address, birthdate, everything.... for some reason though, it looks like the app can't read the contact's name. 

    If i make a change to the contact and 'save' it - the change doesn't actually get saved.

        Hornblower409​ - Thanks!  I actually posted there first... I got a response from a bot, that gave me similar input that Copilot gave me; it didn't work... Someone commented today and suggesting contacting Microsoft support; I did that and after explaining the issue, was told i needed to contact the Outlook for Android group specifically (Haven't had a chance to do that, yet).

        One new piece of advice i got though, from a separate copilot chat was to give the app unrestricted battery access. We'll see if that works
