Here is our scenario. We currently have a Windows 2003 and Exchange 2003 environment (to be migrated to 2012 in near future). We have recently migrated mailboxes to 365 in the cloud with DirSync in place. The Exchange 2003 server is yet to be decommissioned, but all mailboxes are now in 365.
Exchange 2003 was configured to allow all users to view each others calendars ('Reviewer' permission for all). However, since moving mailboxes to the cloud, this particular feature does not appear to have been retained. So my question is, can we globally set calendar permissions to allow 'reviewer' access (except private items) for all other employees in the company?
See attached screenshot of 365 Calendar permissions.
