@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 protected]
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.
