While not the best work around, You can make a Shared Mailbox, designate the person who will be in charge of maintaining the calendar as a delegate with full access to the mailbox. Then change the permissions on the calendar to provide Full read access then you can have your end users add the calendar to their outlook manually. (not ideal for very large organization since you want this done automatically). But till Microsoft can come up with a fix for this, it seems to work just fine.
Problem with Office 365 is its a glorified distribution list with extra features, so its working as intended it sends a distributed invitation to all members of the group. Now at the user level through OWA you can go in and disable notification from this group and the end user wont receive the invitation to their mailbox.Philip supported this idea ·
