Revert to Legacy Outlook for Mac to Access POP Settings

The 'New Outlook for Mac' interface often hides legacy POP configurations. Reverting to the legacy version can restore access to these advanced settings.

Microsoft redesigned the New Outlook for Mac to streamline account setups, which led to the removal of several legacy settings for older protocols like POP3. Reverting to the legacy interface provides access to the classic Preferences menu where server deletion rules reside.

1
Open Outlook for Mac

Launch your Microsoft Outlook application on your Mac.

2
Toggle Off New Outlook

Look for the 'New Outlook' switch in the top-right corner of the application window, or click on 'Outlook' in the top Apple menu bar and uncheck 'New Outlook'.

3
Access Account Preferences

Once the application reloads in the legacy view, go to Outlook > Preferences > Accounts.

4
Configure Advanced Settings

Select your POP account from the left pane, click the 'Advanced' button, and locate the settings to delete messages from the server after a selected period.

Revert to Legacy Outlook for Mac to Access POP Settings
Legacy Support: Microsoft may eventually phase out the Legacy Outlook interface. If the toggle is missing, you will need to rely on your email provider's webmail settings.
