Oulook iOS App - Google Groups Shared Calendar Not Showing up

[Michael She]

Hi all,

I have a problem with the Outlook iOS app and Google Groups Shared Calendars (i.e. a Calendar that is shared with a Google Group e-mail addresss).

1. My regular Google Calendars are syncing fine with Outlook iOS.

2. My shared Calendars are syncing fine too

What is not syncing correctly are my shared Calendars that I distributed via Google Groups. I am the owner of the calendar and they show up fine in Apple Mail and OSX's Calendar app. 

Is this a limitation of the iOS Outlook app not working with Google Groups shared Calendars?

I checked my Google iPhone Sync settings and the calendars are all set to sync.

I tried resetting the account in Outlook, no luck either.

Any ideas?

I updated to iOS 11 and now the Google Groups Shared Calendars are showing up - very strange. Will keep an eye out to see if this problem reoccurs.
