User has a Blackberry (used for years). Notes 7. Now when he moves items from his inbox to a folder, the item moves back into the incoming box. He believes (as I do) that his BB is the culprit. BB says that the email box is too large (13 gigs), but I've seen larger being used with BB without trouble (in the same firm on the same server).
We've done fixup, etc.
Any ideas or has anyone seen this before?
