This usually happens when the RemoteMailbox object is corrupted and the ResourceType field is blank. Since Set-RemoteMailbox -Type Room fails, the quickest fix is to disable and re-enable the remote mailbox (as you noted). Otherwise, you’ll need to manually correct the msExchResourceMetaData / msExchRecipientDisplayType attributes in AD so Exchange recognizes it as a Room mailbox. If re-creating isn’t an option, editing those attributes in ADSIEdit and forcing a sync usually resolves it.
