You discover that a user's photo in the address book in Microsoft Office 365 Dedicated/ITAR (vNext) is not updated or is otherwise incorrect.
This issue occurs because a photo that's larger than 10 KB isn't synchronized to Exchange Online.
Customers must limit the size of users' photos to less than 10 KB in their on-premises environments. Azure Active Directory Sync (AAD Sync) synchronizes photos to Microsoft Azure Active Directory without error if the photos are smaller than 100 KB. However, a photo isn't synchronized to Exchange Online unless the photo is smaller than 10 KB.
