Outlook Group Calendar entries not showing for other users.

[KamCMM]

I have created a Group Calendar in Outlook and have added 5 members to it however, we are experiencing an issue that no one can see the entries that people are putting into the calendar. 

When someone adds a new entry they can see it on their side however, none of the other members can see it on their side. 

Any idea why this could be?

I found an article with a Microsoft Agent's response dated April 15, 2022.

I hope this helps you.

Thanks for your suggestion however, this doesn't appear to be the issues. 

We use cached mode and the group is not hidden. 

Many thanks.
