Archiving emails in Outlook 365 helps manage mailbox size, improves performance, and keeps your communication organized. There are several effective methods, ranging from a quick one-click solution to comprehensive automated processes.
Quick Archiving in Outlook 365
Outlook 365 offers a convenient "Archive" button that quickly moves selected emails to a designated archive folder without deleting them. This is ideal for decluttering your inbox while keeping emails accessible.
How to Use the Quick Archive Feature:
- Select Messages: Open your Inbox or any other mail folder.
- Choose One or More: Click on one or more messages you wish to archive.
- Archive Button: In the Delete group on the Home tab of the ribbon, select Archive.
- Keyboard Shortcut: Alternatively, you can use the Backspace key to immediately archive one or more selected messages.
By default, messages archived this way are moved to a folder named "Archive" within your mailbox, making them easy to find later.
Understanding Different Archiving Methods
Beyond the quick archive, Outlook 365 provides more robust options for managing older emails, especially for users with large mailboxes or organizational compliance needs.
1. AutoArchive (Local PST Files)
AutoArchive is a client-side feature that automatically moves old items from your mailbox to an Outlook Data File (.pst) on your local computer. This helps reduce the size of your primary mailbox, which can improve Outlook's performance.
How to Configure AutoArchive:
- Go to File > Options > Advanced.
- Under the AutoArchive section, click AutoArchive Settings....
- In the AutoArchive dialog box, you can:
- Select Run AutoArchive every N days and set the frequency.
- Choose to Prompt before AutoArchive runs.
- Specify options for deleting expired items or moving old items to a designated folder.
- Set the "Clean out items older than" period.
- Browse to choose a destination file for the archived items (e.g.,
archive.pst
).
- Click OK to apply the settings.
You can also set AutoArchive properties for individual folders by right-clicking a folder, selecting Properties, then navigating to the AutoArchive tab.
2. Online Archiving (In-Place Archive / Archive Mailbox)
For organizations using Microsoft 365 (Exchange Online), an "Online Archive" (also known as an In-Place Archive or Archive Mailbox) is a powerful server-side archiving solution. This provides users with additional mailbox storage space for historical email data, separate from their primary mailbox.
Key Features of Online Archiving:
- Cloud-Based Storage: Archived items are stored securely in the Microsoft 365 cloud, not on your local computer.
- Seamless Access: Users can access their Online Archive directly from Outlook, Outlook on the web, and mobile devices, appearing as a separate mailbox entry.
- Managed by IT: Typically, IT administrators manage the creation and retention policies for Online Archives, ensuring compliance and data governance.
- Unlimited Storage (in some plans): Many Microsoft 365 plans offer nearly unlimited storage for archive mailboxes.
If your organization has Online Archiving enabled, you'll see a folder named "Online Archive - [Your Name]" or "In-Place Archive" in your Outlook folder pane. Emails can be manually dragged into this archive or automatically moved via retention policies set by your administrator. For more details on this enterprise feature, refer to Microsoft's documentation on Archive Mailboxes.
3. Manual Export to an Outlook Data File (.pst)
You can manually export all or selected folders of your mailbox data to an Outlook Data File (.pst) on your computer. This method is useful for creating a backup, migrating data, or archiving specific items outside of the automated processes.
Steps to Manually Export to PST:
- Go to File > Open & Export > Import/Export.
- Select Export to a file and click Next.
- Choose Outlook Data File (.pst) and click Next.
- Select the email account or specific folders you want to export. Ensure Include subfolders is checked.
- Click Next.
- Browse to choose a location on your computer to save the
.pst
file and name it. - Select an option for handling duplicate items.
- Click Finish. You can optionally set a password for the
.pst
file.
