I have multiple Microsoft Exchange accounts. One is my main account (call it email@example.com); two others belong to clients that I support, and they have they own domains and their own distinct instances of Exchange (call the accounts firstname.lastname@example.org and email@example.com). Is it possible to enter a calendar event (say, a meeting) in my main Exchange account (firstname.lastname@example.org) and have that event automatically show up in the Exchange calendars associated with email@example.com and firstname.lastname@example.org? My goal is to keep the calendars properly synchronized so that clients at those distinct companies can look at my calendars and know when I'm available for meetings. Right now, I create a meeting in the calendar associated with the email@example.com accoutn and then I have to mail invitations to myself at firstname.lastname@example.org and email@example.com. Then I have to go in and accept all those meetings, turn off the default reminder times, set this one or that as Private, etc--and all that's a pain.
