Shared Group Calendar in Outlook (office 365) is saying couldn't be updated

[skakooza]

Hi AllI have created a group mail box and added 28 staff emails. I want all group members of an established O365 group to be automatically subscribed to it. which works fine.All team members can see it in OWA but couldn't see it Outlook. So each member I believe has to add that group under their other calendars in Outlook.Now the issue I have is that it works fine on the web (OWA) but they cannot add events while in outlook clientAnyone one out there has come up with a similar error "couldn't be updated" in Outlook. And when I click on the error message at the top it seems to say I don't have permission yet am the group owner.Please helpRegardsStephen
