Disable @ mentions in Outlook 365

@mentions can be very handy at ‘tagging’ people into an online conversation but they can also be a damned nuisance.  Here’s how to disable @ mention in Outlook 365 for Windows.

Microsoft has added @ mentions throughout the Microsoft 365 services including Teams and Office document collaboration.  It’s great for tagging someone and bringing them into a conversation.

In Outlook for Windows, type an @ alone and a Mention list will appear based on personal and organization contacts.

That’s OK in organizations or people linked into a company, but for many personal or small business users @mentions have no place.  That’s because the people being @mentioned aren’t using the same integrated Microsoft service.

Or maybe you use @ for other purposes and the prompt is just annoying?  The Mention prompt only appears if @ has nothing preceding it, in other words it won’t show if you’re typing an email@address.

Stop @mentions list

Go to File | Options | Mail | Send Messages.

Uncheck the box “Suggest names to mention when I use the @ symbol in a message (requires restarting Outlook)”.

This option first appeared in Outlook 365 for Windows  v2007 build 13029.20200 in mid-July 2020.
