Online archives in Outlook store older emails and can be removed through account settings. If you’re wondering how to remove online archive from Outlook, you’re not alone—many users find these archives cluttering their mailbox or taking up storage space. This guide walks you through every method, from simple desktop steps to advanced PowerShell commands, so you can clean up your Outlook without losing important data.
An online archive in Outlook is a separate mailbox folder that automatically moves old emails to reduce your primary inbox size. While useful, it can become bloated or cause sync issues. Removing it is straightforward once you know where to look.
Before we start, note that deleting an online archive is permanent—you cannot undo it. Always back up any emails you want to keep before proceeding. Let’s dive into the step-by-step process.
How To Remove Online Archive From Outlook
This section covers the primary method using Outlook’s account settings. It works for both Microsoft 365 and Exchange accounts. Follow these steps carefully.
Step 1: Open Account Settings
Launch Outlook on your computer. Click on “File” in the top-left corner. From the menu, select “Account Settings” and then “Account Settings” again from the dropdown.
Step 2: Locate The Online Archive
In the Account Settings window, you’ll see a list of your email accounts. Look for the account that has the online archive. Click on it once to highlight it. Then click the “Change” button above the list.
Step 3: Access Archive Settings
A new window titled “Change Account” opens. Here, click the “More Settings” button in the bottom-right corner. This opens the Microsoft Exchange settings dialog.
Step 4: Remove The Archive
In the More Settings window, go to the “Advanced” tab. You’ll see a section labeled “Open these additional mailboxes.” This list includes your online archive. Select the archive entry (it often looks like “Online Archive – Your Name”) and click “Remove.” Then click “OK” to close the dialog.
Step 5: Restart Outlook
Click “Next” in the Change Account window, then “Finish.” Close all Outlook windows and restart the application. The online archive should no longer appear in your folder list. If it still shows, repeat the steps or try the alternative methods below.
Alternative Method Using Outlook On The Web
If the desktop method doesn’t work, you can remove the archive via Outlook on the web (OWA). This is especially usefull for users with limited desktop access.
Access Outlook On The Web
Open your web browser and go to outlook.office.com. Sign in with your work or school account. Once logged in, you’ll see your mailbox with the online archive listed on the left sidebar.
Navigate To Archive Settings
Click the gear icon (Settings) in the top-right corner. At the bottom of the Settings pane, click “View all Outlook settings.” In the settings window, go to “Mail” and then “Archive.”
Disable The Archive
Under “Archive policy,” you’ll see an option to “Turn off archive.” Toggle this switch to off. A confirmation dialog appears—click “Yes” to confirm. The online archive will be removed from your mailbox after a few minutes. Refresh your browser to see the change.
Using PowerShell To Remove Online Archive
For IT administrators or advanced users, PowerShell offers a powerful way to remove online archives in bulk. This method works for Exchange Online and requires admin permissions.
Connect To Exchange Online PowerShell
Open PowerShell as an administrator. Install the Exchange Online module if you haven’t already: Install-Module -Name ExchangeOnlineManagement. Then connect: Connect-ExchangeOnline -UserPrincipalName admin@yourdomain.com. Enter your admin credentials when prompted.
Identify The User’s Archive
Run this command to see the archive status: Get-Mailbox -Identity user@yourdomain.com | fl *archive*. This shows if an archive exists and its status.
Remove The Archive
To delete the archive, use: Disable-Mailbox -Identity user@yourdomain.com -Archive. Confirm the action when asked. The archive is removed immediately. To verify, run the first command again—the archive fields should now be empty.
Bulk Removal For Multiple Users
If you need to remove archives for many users, create a CSV file with their email addresses. Then run: Import-CSV C:\users.csv | ForEach {Disable-Mailbox -Identity $_.Email -Archive}. This processes each user in the list.
Removing Archive From Outlook For Mac
Outlook for Mac handles archives differently. Here’s how to remove an online archive on a Mac system.
Open Outlook Preferences
Launch Outlook for Mac. Click “Outlook” in the menu bar and select “Preferences.” In the preferences window, click “Accounts.”
Select Your Account
Choose the email account that has the online archive. Click the “Advanced” button at the bottom of the account settings window.
Remove The Archive
In the Advanced settings, look for “Archive mailbox” or “Online archive.” Uncheck the box next to it. Click “OK” and close the preferences. Restart Outlook for Mac to complete the removal.
What Happens After You Remove The Archive?
Understanding the consequences helps you avoid data loss. Here’s what to expect.
- All emails stored in the online archive are permanently deleted. They don’t go to your Deleted Items folder.
- Your primary mailbox size may increase slightly if you had auto-archive rules moving emails.
- Any retention policies tied to the archive stop applying to those emails.
- You cannot recover the archive once removed—no recycle bin exists for it.
To prevent data loss, export the archive emails first. In Outlook, select the archive folder, go to “File” > “Open & Export” > “Import/Export,” and choose “Export to a file.” Save as a PST file for future access.
Troubleshooting Common Issues
Sometimes the archive won’t remove easily. Here are fixes for frequent problems.
Archive Still Shows After Removal
If the archive persists, try clearing Outlook’s cache. Go to “File” > “Options” > “Advanced.” Under “Outlook start and exit,” click “Browse” and rename the “Outlook Files” folder. Restart Outlook—it rebuilds the cache. Alternatively, use the /cleanviews command: press Windows+R, type outlook.exe /cleanviews, and press Enter.
Cannot Find The Archive In Settings
Some accounts hide the archive setting. Check if your organization has policies preventing removal. Contact your IT admin. For personal accounts, ensure you’re using the correct account type—only Exchange and Microsoft 365 accounts support online archives.
Error Message When Removing
Errors like “Cannot remove archive” often indicate permission issues. Make sure you’re the mailbox owner or have admin rights. Try removing the archive from Outlook on the web first, then sync your desktop client.
Preventing Future Archive Clutter
Once you remove the archive, you can avoid it reappearing. Adjust your mailbox settings to prevent automatic archiving.
Disable Auto-Archive Rules
In Outlook, go to “File” > “Options” > “Mail.” Under “AutoArchive,” click “AutoArchive Settings.” Uncheck “Run AutoArchive every N days.” This stops Outlook from moving old emails to an archive.
Set Retention Policies
For Exchange accounts, admins can set policies that delete old emails instead of archiving them. In the Exchange admin center, go to “Compliance management” > “Retention policies.” Create a policy that deletes items after a set period.
Use Folders Instead
Manually move old emails to a local folder in your primary mailbox. This keeps your inbox clean without creating an online archive. Right-click your mailbox, select “New Folder,” and name it “Old Emails.” Drag messages into it.
Frequently Asked Questions

Yes, you can re-enable it through account settings or by asking your admin to turn it back on. However, the old emails are gone unless you restored them from a backup.
Final Tips For Managing Outlook Archives
Removing an online archive is just one part of mailbox maintenance. Regularly clean up your inbox by deleting unnecessary emails and emptying the Deleted Items folder. Use search folders to find old messages quickly without archiving. If you have a large mailbox, consider upgrading your storage plan instead of relying on archives.
Remember that the exact steps for how to remove online archive from Outlook may vary slightly depending on your Outlook version (2016, 2019, Microsoft 365) and your email provider. Always test the process on a non-critical account first. If you’re an admin, use PowerShell for efficient bulk removals—it saves time and reduces errors.
