Since Shared Mailboxes will not show up in many of the menus available in Outlook, Out of Office messages for shared mailboxes should be set through OWA.
- Log into OWA.
- Go to Settings, and search for Automatic Replies.
- Click on it and set up all the necessary options.
If you prefer to use Outlook, menus can be made available for the Shared Mailbox by sending a message to email@example.com requesting to have Automapping disabled.Tags: Office 365, UTmail+
