ios 17 Calendar Issue - Outlook

Hallo -

I am having an issue with ios17 and Outlook email on a work email account:


I am using ios17.0.2. When I receive a meeting invite from an external account it is going to my junk mail. However, it appears in my iPhone ios native Calendar app. If I accept the invite in the app i receive an error on my phone, however, my Outlook account the sends a meeting invite, from my Outlook profile, to all the recipients of the original meeting, under my name. It's bizarre.


We've narrowed it down to ios 17 by doing the following:


Running the issue on 2 other phones. Both iPhone 14. One running ios16, the other running 17.0.2. Both phone's were wiped clean prior to testing.


  • When we ran the invite test on ios 16 the invitation was in my Outlook junk folder. It appeared in the native calendar app. When hitting "Accept" the phone simply gave me an error that it couldn't accept an invite and send the response.
  • When we ran the test on the phone with ios 17 it provided the exact same error, however Outlook then generated its own invitation, with the same subject heading as the one I received, and sent it to the entire distribution list of the original invite, except with a different time and under my account.


Needless to say, this is creating some confusion and wreaking a bit of havoc.


Thoughts?

iPhone 7, iOS 13

Our initial testing so far shows that this was resolved in 17.1 in the invites that hit junk mail originally. Attempting to accept the invite while it's in junk is no longer generating a new meeting invitation for 30 minutes into the future.


Not sure if it's resolved for the version Spare_Ribs metioned in his post. Can anyone confirm if it's still happening on the recurring meeting invitation that's been canceled?


Thanks,

Hadi
