Outlook Group Calendar entries not showing for other users.

Copper Contributor

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?

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.
