1987862 - [ews] EWS folders never have the `Offline` folderflag set by default.

Status: RESOLVED FIXED

(MailNews Core :: Networking: Exchange, defect)

Description

Some (most?) EWS folders should be flagged for offline use to indicate they should download messages to the local store.

Not sure where this happens for IMAP, but I suspect the rules and mechanism would be the same (INBOX always marked Offline by default, but not the Trash folder, etc....)

Taking a quick peek through the IMAP code:

There's an attr on the IMAP server object which says if the newly-created folders should have the offline Flag set:

Folders with Trash or Junk flags are not marked offline:
