Hi everyone, hope someone can help before I’ve no hair left to tear out!

I’ve got a user who somehow has an incorrect number populating a field in Teams & Outlook that we typically do not use:

We populate the first “mobile” field (with the old-school handset icon) from the Mobile field in Active Directory under the Telephones tab, and everyone has a number there. This guy somehow has a second number showing in the one with the green arrow pointing above, with the little mobile phone icon. I have scoured through every field and attribute in AD and in Azure and cannot find anywhere this number is stored. I’ve searched everywhere I can think of for hours. Does anyone know where that field pulls data from?

Pre-emptive thanks if anyone can help solve the mystery!

Contact in their own address book?

Syncing from a mobile devices contacts?

If it’s visible to everyone, it’s in AD or teams profile for that person.

If it’s only visible to selected people, for example this one user, it could be in their own address book or contacts list.

If they have linkedin integration enabled, it could also be coming from there.

Thanks for the reply. It’s visible to everyone, and definitely not in AD. Syncing from LI or other external apps wouldn’t be allowed either. I didn’t think we could even edit our own contact details in the profile–most options are greyed out and “managed by your administrator” for them. I’ll see if I can get hold of his phone and have a look around, though. Cheers.

If everyone can see it, it has to be coming from a central place.

AD / AAD, or your EXO address book.

The only other places are Teams (user input in to their own profile), Linkedin if they are allowed integration and Graph API form another app.

If you sync AD it comes from the mobile number field on the Telephones tab in ADUC, which if you’re looking up in Powershell will be the mobile and MobilePhone attributes.

Thank you. His first number is syncing from that field (as it should). It’s that second one that seems to be coming from nowhere. I’ll go digging in PS again, cheers.

Could be the an other phone attribute.

Get-aduser username -properties * | format-list

See if that number shows up in any of the fields.

If you check Outlook’s address book (Global Address List) is it there also, in the offline save? Could this be a custom field in AD? If you go into the AD properties and click on Attribute Editor, then the Filter button at the bottom, make sure you’re not accidentally hiding some of the results and then check again.

My team recently resolved a problem like this, a user had his personal cell populated in the GAL but it was not coming from AD, Entra, Exchange, or WorkDay integration.
The solution was that somehow that number had been entered into his MS Sharepoint profile. Once we removed that entry the number disappeared from all the other places (after sync time delays, of course)

@AdmiralKirk Have you noticed if you’re in a 365 portal and you click your picture and select “My Microsoft 365 profile” it now takes you to a copilot page?

Oh, I hadn’t even thought of checking SharePoint! Hopefully, OP gets that note as well!

I noticed that when I open office.com it goes directly to a Copilot page. Just noticed it today actually.
Is that as supremely annoying to you also? If I wanted to access Copilot stuff I’d go to copilot.office.com, like when i want Entra stuff I go to entra.office.com.

I know it syncs with AD/Azure/Entra ID, for us HR provides a feed to populate AD.

I did notice this, and it’s really annoying. I’ve no idea what it’s meant to actually accomplish.

You’re a genius!
Never in an era would have thought of this. Had to look up how to even access individual user profiles in Sharepoint, but sure enough, there it was.
THANK YOU!

And thanks also to everyone else who offered suggestions. Certainly was good to be thorough and have one thread full of just about every possible place this could sync from :smiley:
