Multiple Emails and Integrated Calendar

[littlefleckofdust]

How do I get invites sent to multiple emails to appear in a single integrated calendar?

I have email1, email2, email3 (all happen to be gmail emails). I've added the email1 gmail calendar. I want to get invites sent to all three to appear in the email1 calendar. Somehow, email1 and email2 do, but email3 gives an error "80004005".

Bonus points if there's a way to get invites from the calendar to show as my email1 alias instead of as email1.

Thank you in advance.
