Department-Wide Organizational Mailbox (OMB)
An OMB is created by the ITS server team and is used by a group or department. This is the preferred shared mailbox system.
- Once you've confirmed you've been added as a member of the shared mailbox, close and restart Outlook.
- The shared mailbox should automatically display in the Folder pane.

What if it didn't work?
- After the admin adds you to the shared mailbox, it may take a few minutes before it appears. Wait a bit longer, and then close and restart Outlook again.
- The shared mailbox will appear in the Folder pane beneath all of your account items. Collapse your account to see all mailboxes that are available.
- If it still doesn't appear, then continue with these steps. If those don't work, please submit a request for Email Support.
