Outlook Mobile now allows users to create delegates for their mailbox in the app without going near administrators. Sounds good, but Outlook Mobile uses its own delegation model, meaning that its permissions don’t work with OWA or Outlook desktop. Using its own permissions might make Outlook Mobile users happy, but it’s a very strange approach to take when the access doesn’t work in the other clients.
Sometimes delegate access for an Exchange Online calendar goes awry due to corrupted items in the mailbox. To help sort out problems, Microsoft has upgraded the Remove-MailboxFolderPermission cmdlet to do the work that used to be done by a multi-phase fix performed using the MFCMAPI or EWS editor utilities. The nice thing is that this method is quick, simple, and works well.
Outlook Mobile now supports delegate access to Exchange Online mailboxes. By granting fuil access to a delegate, they can open and work with a mailbox, and send messages using the SendAS or SendOnBehalfOf permissions. The new feature underscores the advantage Outlook mobile enjoys over other mobile Office 365 email clients.
