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

the I am on IoS 17.0.3. I do not see “Edit” option for event invitations sent from Google calendar. As I said, I do not have an option to delete this invitation. The only options that are provided are “Accept”, “Maybe” or “Decline”. I declined the invitation, and it is showed as such, but it is still in the Calendar. I would like to completely remove it from the Calendar, but there is no such an option. However, the events I created (not the ones sent to me), are fully manageable and I can modify or delete them without any problem.

Do you mind pointing me toward other threads? Hoping to gather more intel to share with my company's IT. Has happened to me twice, including with 17.0.3, so it hasn't been fixed yet. (For me, it's been with in-company invitations, not in junk mail, but otherwise, identical.)


(Such a bummer--very disruptive and inappropriate to be spamming hundreds of people with an invite to a meeting I don't own, proposed for 9pm or whatever time I happen to Decline the original invite!)


Thanks.

Oct. 11 Update--I contacted support, I have an ongoing ticket open. Of course I had to explain that no it's not something I'm doing, no I can't reproduce this for you live, no there's nothing to see in the Calendar inbox screen that tells you anything useful; I sent some screen shots, hoping to hear back this week or next. Will update this thread. The fact that I had other support discussions on this site to direct the rep to was very helpful in conveying that it's not just user error or Microsoft's fault--thanks all for documenting this here!
