While attempting to license a user for only MS Office (or any other license) the the Admin Center, I received an error that I must also license them for Exchange Online and Sharepoint as it contains Outlook Customer Manager (Attached Screenshot). This was not the case a day or so ago. However, I can license them through the IOS Admin App and possibly powershell.
Any word on a fix for this issue? I am just glad I found a work-a-round for the moment.
