i have noticed 1 or 2 accounts in our tenant now have a set of random alphanumeric characters in the principle name.

 

for example:

 

2cc628bba6264fb184bc02ee729abdbcJoe.Ninety@Mail.Com

 

only a few accounts have this.... Including some resource accounts?  Any idea what the cause could be.

Are they existing users whose username has been changed, or are they new / additional users?

Do you have AAD Connect installed & configured on-premises?
