Insider Fast: @Mentions for Outlook Mac is now available in Insiders Fast!

Hi Everyone, 

@Mentions for Outlook Mac is now available in Insiders Fast! We'd love for you to try it out and let us know what you think about it. The Insiders Fast Outlook Mac version update number is 15.25 (160726)

@mentions make collaborating on email fast and easy. Simply type the @ symbol anywhere in the body of your email and start typing to pick the person you want to address. Once you select the person you want to address, their name is highlighted in the message in blue, helping them know they are being asked to take an action in your message. In addition, if the person isn’t part of the email conversation already, they will be automatically added to the To: line so they receive a copy of your email.

In addition to helping you get other people’s attention, @mentions also helps you be aware of what you’ve been asked to do. Outlook adds an @ symbol in the message list for the messages you’ve been mentioned in, so you can see at a glance which emails require your action before you open them. We have also added it as a filter [View or Ribbon-Filters-Mentioned] so you can filter to see only the messages where you’ve been mentioned. Once you’ve opened the email, the blue highlighting of your name in the body of the email helps you quickly find where you’ve been mentioned.

@Mentions is available for users with Office 365 subscriptions. 

Q. What email accounts will @mentions work for?
A. The sender features of @mentions will be available to all—regardless of the type of mailbox or email service you are using in Outlook. The recipient features of @mentions (message list improvements, blue highlighting in reading pane) are only available for recipients using Outlook with Office 365 or the new accounts.

This doesn't seem to be working for me in 15.25 (160726).  If i type "@" in the body of a new message and start typing a name nothing happens.  It appears to be treated just like normal text.  Did I miss a step?


Can you please go to the Top Menu > Outlook > About Outlook and send me a screenshot of your About Outlook window? 



Sure.  I did read above that this is applicable to Office 365.  From the screen shot it looks like i'm using the VLSC copy, but i could of sworn I uninstalled that and installed the 365 copy.  So i'm not sure if this is the reason for what i'm seeing, and if so, if i need to do something special to change over to the 365 license.

Hi Jason! 

If you are an Office 365 subscriber, here's how you can reset your subscription: 

  1. Quit all Office 2016 apps
  2. Delete the file /Library/Preferences/
  3. Run ‘killall cfprefsd’ from Terminal

Launch Outlook and sign in using the email address you use for your Office 365 subscription. 



Excellent, that did the trick.  Thank you
