Microsoft yesterday released a new update for Office apps for iOS and Android Insiders. With this Slow Ring update, Microsoft is bringing @mentions support for PowerPoint, Word, and Excel! Let your co-workers know you need their help or input, right from the document you are working on.
Get their attention with @mentions (Word and PowerPoint)
Use @mentions in comments to let co-workers know when you need their input.
Collaborate effectively with comments and @mentions (Excel)
Keep the conversation going right in your worksheet with the built-in reply box and let co-workers know that you need their input by using @mentions.
If you are in Insider, you can download these updates on your iOS for Android devices and give these new features a try.
