Hello all,
We've had many conversations about the read-only capabilities in regards to IMAP folders and we're not seeing a good solution with our current implementation.
The way we're allowing users to subscribe to shared folders is not the normal way to connect to a share via IMAP. Normally you would have to connect to the other person's mailbox to view those folders and wouldn't have the option to directly subscribe from your own mailbox. This is why you see undesired results when trying to delete, flag/unflag, and mark as read/unread against shared folders. We properly return error codes but unfortunately each client seems to react to these errors differently.
Because of these inconsistencies from each client, we've decided to not allow users to connect to read-only shares via IMAP. It doesn't bring the correct user experience in its current implementation. However, we will allow users to subscribe to full control folders. We'll be generating a KB article to explain our reasoning around this change for future reference.
We apologize for these sudden changes but having the correct user experience made this the right call.
