I've created a company "vacation" calendar by first creating a shared mailbox. I want everyone in the company to have author permissions for this calendar - to create and edit their own entries.
From my Outlook client, I have set the permissions and double-checked them for everyone to be an author or owner. But, when the calendar is accessed on the employee's Outlook client they only have review permission; they can not create or edit new appointments. Some are able to create an event invitation only, but no appointments.
Also, in OWA, I created several "other" calendar subfolders within the "vacation" calendar. These sub-calendars appear complete in my Outlook client, but do not appear at all on the other employees' Outlook. Do I have to send invitations for each sub-calendar to every employee?
Up to this point, I am working only with OWA and Outlook. I have not delved into PowerShell. Do I have to go there?
