MailTips cannot be turned off or changed in Outlook Classic

Question

Outlook version: Microsoft® Outlook® for Microsoft 365 MSO (Version 2606 Build 16.0.20131.20152) 64-bit

I am trying to turn off MailTips (or change which MailTips appear) when I create or reply to an email. I have repeatedly gone to File>Options>Mail>MailTips Options and unchecked specific MailTips. I have also tried clicking "Never display MailTips".

I hit OK and sometimes immediately MailTips reappear and the settings revert to default, If not, then when I have closed outlook and opened it (Either immediately or after a restart) MailTips has reverted to the default display settings and will show up again.

I have also turned off the Optional Connected experiences and this has made no difference.

Is there a way I can turn off MailTips, or specific tips in a way that they will stay off? Perhaps through a Powershell command or editing a registry key?

Hi BP

According to Microsoft documentation, MailTips can be disabled from File > Options > Mail > MailTips Options by selecting Never display MailTips or by clearing specific MailTips. Since the setting is reverting to its default state aft r Outlook is restarted, this is not the expected behavior.

If you are an end user, I recommend contacting your organization's IT administrator first. In managed environments, Outlook settings may be controlled by organizational policies (such as Group Policy or Intune), which can override user preferences and restore MailTips settings after Outlook is restarted.

If you are the administrator, or if your IT team confirms that no policies are enforcing these settings, could you please let me know:

• Does the issue occur when Outlook is started in Safe Mode (outlook.exe /safe)?
• Does the behavior persist with a newly created Outlook profile? (Create an Outlook profile | Microsoft Support )

I also did some research, but I am not aware of any supported PowerShell command or registry setting that is specifically intended to keep a user's MailTips display preference disabled when Outlook reverts the setting after restart. MailTips can be configured at the Exchange organization level, but those settings primarily control MailTips availability rather than whether an individual user's Outlook preference is retained.

If the issue continues after testing with a new Outlook profile and Safe Mode, the behavior may require investigation by Microsoft Support, as it could be related to Outlook configuration persistence rather than the MailTips feature itself. For further instructions, you can follow this guide: Get support - Microsoft 365 admin | Microsoft Learn.   

I look forward to your update.
