Receiving requests on Authenticator app from removed account?

Question

Dear all,

I have a specific problem that I can't seem to find a solution to anywhere. The situation is as follows:

A customer of mine claimed that there was a problem with the Office 365 account in combination with the Authenticator app on the iPhone. In order to show that it wasn't the Office 365 account that caused the problem, I added the account to my personal Microsoft Authenticator app. I showed that everything worked fine, and removed the account from my phone. All was well. Case closed?

Not actually. Later I noticed I was still receiving push notifications within the Authenticator app. At first I thought one of my accounts had been compromised, but when I opened the app there were no notifications. I figured it must have been the account of the customer that I removed that was still sending push notifications to my phone.

I can't remember the name and phone number of the customer, so I'm unable to contact them. The daily series of ghost notifications on my phone is becoming a bit of a nuisance. I have removed the Authenticator app from my phone, and re-installed it from the App Store. But the notifications immediately returned.

Is there any way to remove this account from my Authenticator completely? Or see who's e-mail address it is that is sending the notifications, so I can contact the owner?

Thank you for any suggestions!

Hi Just_Kelvin,

When you tap on the notification, you should be able to see which email address requested the sign-in and from which location.

Once you have that information, you need to contact them and instruct them to navigate to https://mysignins.microsoft.com/security-info and remove your phone from the list of sign-in methods.

Only the owner of the account can do this, because they need to be logged in.
