It is on IPhone and IPad, cannot speak for Android, as I do not use Android, downloaded from the App store.
Kurt,
Is this an update in IOS or Android?
An update for Outlook on Android or iPhone? I don't see it on Android.
Please make sure that you update your app, as there is a new version and it now works, thank goodness!
I don't know how to explain it but my Outlook app hasn't updated since March 29 and my last Android was last updated on April 5, go figure. Everything broke on April 24.
It clearly has something to do with the MS Outlook app because the native GMail app is working just fine and OWA also works fine.
