It seems if you have Full Access mailbox permissions, you can access the alternate mailbox but if you grant MAPI permissions on the calendar object it doesn't work. Not a solution of course but it seems worth noting.

Just about everything is working, however accessing another calendar via the url https://owa-fqdn.com/owa/[email protected]/?cmd=contents&module=calendar does not work. All user mailboxes still on Exch2010. The OWA url hits an F5 load-balancer and proxies for all the Exch2010 CAS. Let me know if you need other information. Exch2013 is at CU5; Exch2010 all but maybe the latest RU. Thanks in advance. Peter
