Archiving of mailbox items is done based on policies. The default policy, which is applied to all mailbox folders, is to move the item (email) after 2 years to the online archive.
Good to know is that the folder structure of your inbox is automatically re-created in the Online Archive. So if you have for example a subfolder Invoices in your Inbox, then you will get the same subfolder in the Online Archive:
Manually move items to Online Archive
It’s also possible to manually move items to the Online Archive. This is useful when you want to clean up your mailbox or are running out of storage space
- Select the items that you want to move to the Online Archive
- Right-click on the selected items
- Choose Move and select the Inbox – Online Archive folder
Don’t use the Archive button in the toolbar, because that will move the selected items to the archive folder in the primary inbox.
Searching in Online Archive
When you search for an item in Outlook it will by default search in the current mailbox. To search in the online Archive as well you will need to select All Mailboxes next to the search field.
