Access archive mailbox in Outlook
To provide users with more mailbox storage space, Seton Hall University has enabled the archive mailbox option in Outlook for all employees. By enabling this option, a user's current mailbox becomes their primary mailbox and an additional mailbox is created, called the archive mailbox.
This option automatically moves messages older than two years to the archive mailbox. However, you can still search for, move and copy messages between your primary mailbox and your archive mailbox.
Search for Archived Messages
If you are using the Outlook app for Windows, you can search for messages in your archived folder by:
Clicking into the search box at the top of your screen. A new menu appears displaying Current Folder as the default search setting.
Click the down arrow to expand the menu, then select All Mailboxes.
Now, when you type in your message keyword, the search will include results from your archive mailbox.
If you are using Outlook on the Web, the search settings default to “All Folders.” You do not to change any settings for messages from your archive mailbox to be included in your results.
