I have double and triple checked, as well as my system admin and everything looks good on our end and we do have a license applied so I dont know why it says the account doesnt.

Answer 1

Dear Joe M in IT,

Thanks for choosing Microsoft Community.

Based on your description, I know the scenario you met. For this, situation, since you said that you have already applied License services but still user cannot access mailbox account, so I think the cause of the problem is most likely due to an error on the server backend, because our forum lacks relevant knowledge and permissions, so to better help you, please kindly try to create a service ticket in the Microsoft 365 admin center to support > service requests through navigation, as they have more access permissions than on this forum, and professional engineers will further help you. Thanks in advance for your understanding! Your patience and cooperation will be highly appreciated. Hope you all the best!

Sincerely,

Katherine

The issue was resolved by removing the license and then re-applying the license.
