I have a user with hundreds of subfolders within subfolder in his Inbox, Sent items and Deleted Items folders, plus a few user-created folders in the root of the mailbox. Some of these folders have long names and many of them are empty.
I've been unable to activate an EVO device, the device sits there for a long time and eventually stops and I get a message that reads "error" and nothing else.
When I check the mobile device settings in exchange management console I get a type of MOTOBUR30, which I assume is the OS, but no User Agent.
I've successfulyl activated the device with a different, more normal, mailbox.
Is the culprit the user's mailbox folder structure?
