Remote meeting request emails with no buttons

[Doug L]

Our company tries to send out meeting requests to other companies outside of
our Exchange server and all they get is an email message with no buttons to
accept or reject the meeting request, can anyone help?

We have exactly the same problem, still no solution. I all began since the
implementation of Exchange Server 2007.

We have an Echange 2007 organization. All clients have Outlook 2003. When
they send an calendar invitation to each other it work without problems. But
when we send a calendar invitation to an external recipient (by e-mail
adress), the recipient does receive the invitation, but there are nog
buttions available do accept or decline. It seems to be in HTML format.

The weird thing is, when we use Outlook 2007 to send the calendar invitation
it all works fine.

What is causing this issue?
