Question details

The user is trying to permanently delete emails and junk messages from Outlook, but the deleted items continuously reappear.

Product: Microsoft Outlook
Device & OS: not provided
Scenario: Cleaning up the inbox and emptying the Junk Email folder on Outlook web and desktop applications.
Observed behavior: Emails that are deleted or removed from the Junk Email folder keep reappearing, leaving thousands of unwanted messages in the account despite repeated deletion attempts.

Before you start

Ensure your device is connected to a stable internet network so Outlook can properly sync your local deletion actions with the Exchange server.

Solution 1Recommended

Permanently Purge Recoverable Items

Often, items removed from the Deleted Items folder are moved to a hidden Recoverable Items folder. Emptying this folder can stop emails from syncing back to your inbox.

When you delete an email in Outlook, it first goes to the Deleted Items folder. Emptying that folder moves the emails to a secondary hidden location designed to prevent accidental data loss. Purging these recoverable items forces a permanent deletion across the server.

Empty the Deleted Items folder

Open Outlook on the web or desktop, right-click the 'Deleted Items' folder in the left navigation pane, and select 'Empty Folder'.

Access Recoverable Items

Click on the 'Deleted Items' folder. At the top of the message list, click the link that says 'Recover items deleted from this folder'.

Purge the emails

In the Recoverable Items window, select all the messages you want to permanently delete, and choose the 'Purge' or 'Delete' option to remove them completely from the server.

Solution 2

Check Microsoft 365 Retention Policies

If emails continue to return after purging, server-side retention policies set by your organization may be overriding your local deletions.

Frequently Asked Questions

Why do my deleted emails keep coming back in Outlook?

This typically occurs due to synchronization issues between your local Outlook app and the email server, items lingering in the hidden 'Recoverable Items' directory, or organization-level retention policies that prevent permanent data deletion.

Can I disable Outlook retention policies myself?

No. If you are using a work or school account, retention policies are controlled globally by your IT administrator through the Microsoft 365 Admin Center. You must contact them to make any adjustments.

How do I empty the Junk Email folder permanently?

Right-click the Junk Email folder and select 'Empty Folder'. To prevent these junk messages from returning, immediately go to your 'Deleted Items' folder, empty it, and then purge the 'Recoverable Items' folder as well.

Does this issue happen only on the Outlook desktop app?

No, this syncing and retention issue frequently affects both the Outlook desktop application and Outlook on the web simultaneously, because the root cause usually lies within the Exchange server itself.
