Deleting old emails can be risky — you might lose something important. That’s where Archive comes in. It moves older messages out of your inbox without actually deleting them.
To use Archive (Desktop Outlook):
- Select the emails you want to move.
- Click Archive in the toolbar.
You’ll still be able to find them anytime under the Archive folder or by searching.
💡 Bonus tip: Go to File → Tools → Mailbox Cleanup to see how much space your mailbox uses and quickly archive large or old messages.
Result: your inbox stays light and fast without losing data.
