Odd Calendar Sharing Issue

[John]

One of the users in my organization cannot share out his calendar. When he
selects share calendar he can send out the calendar sharing invitation but
when the recipient gets the calendar sharing invitation there are a couple of
odd things.. First there is a highlighted message that says "This sharing
message is not valid. All action buttons have been disabled" and sure enough
the "Open this calendar" option at the top of the E-mail message is greyed
out. Second we see a "(Sender not verified) - Calendar) message in the email
as well.

I have looked for resolutions to this issue on microsoft technet as well as
the internet and cannot find a resolution... HELP PLEASE I need to get this
issue resolved ASAP since this account belongs to the new president of our
organization that starts today so any help would be greatly appreciated!!!

Thank you all in advance!

Well I finally figured out the answer to this issue on my own. If this ever
happens to any of you here is the solution:

You will need to open up the user's Active Directory account in AD users and
computers and put their email address in the email filed on the general tab
of the users properties page.
