Adding phone number as alias

Edwina Lukban 1 Reputation point

I removed my phone number as alias, by mistake. When I'm trying to add the number again, I get the message "This alias cannot be added to your account. Choose a different alias." What should I do to re-add my phone number?

    Hi @Edwina Lukban

    Could you login your account normally via phone number after you deleting phone numbers from your account?

    In this case, we recommend you check if you have deleted your phone number completely. I did a test in our environment and it seems no issue. Here is our steps for your reference:

    1) Sign in to Manage how you sign in to Microsoft.

    2)Remove phone number in Account aliases.

    3)Add phone number to account.

    Even I've the same problem, I'm unable to add my number which I deleted by mistake as secondary alias. After talking to Microsoft support, they assured me that you can re-add the number. But every time I try to add I failed.
