Thanks, so I recently added a MAPI email account to my Outlook desktop. My main account is Office 365 for Business. I can see that calendar, but I notice on my Desktop, I don't have a Calendar for my new account....though. I wonder if it's related to what your default email account is then? I can only see my default email account calendar.
Ahh...OK. Sorry James, I may have reached the limit of my ability on this one. Is the default account, an Exchange account? My only other suggestion would be to reset both accounts or maybe even delete the new one you have added and repeat the process. Other than that, hopefully someone more knowledgeable than me can help you sort this... Geoff
