I just set up a new user in ADUC and then put their nice shiny new email address in the email box.
We use AAD Connect so my next step was to force a sync. After going into O365 to configure the correct license for the user I realized I had made a typo in the email address.
I fixed it in ADUC and did another forced sync, but the wrong one is still showing in O365. Do I just need to be patient for it to update or am I doing this wrong? Should I be doing something else to fix this?
