We recently performed a bulk migration of all shared/resource/mailboxes from Exchange 2010 to Exchange 2016, and according to migration report batch, everything was successfully migrated and no errors.
After some weeks, some of my clients are reporting errors within outlook when moving emails from their inbox to a legal corporate application.
This legal application allows people to save all their email/attachments received within the department.
The following error is listed. This particular error occurs when users are trying to move certain email, with images, from an additional mailbox account[their boss]
If this particular email was moved to their own inbox and then processed again through the legal application, the error will not show. After doing numerous test, it was determined that emails with an image within the body caused this error.
This is occurring in office 2013 and 2016 with Windows 7 and Windows 10 machines. All users in that particular department are experiencing the issue.
Other shared/resource mailboxes and the email infrastructure is OK, no email flow issues, no other issues reported so far.
