I have loaded Outlook 2007 Beta 2 and have hit a snag. When I send an invite
to a meeting, the meeting disappears, no-one gets the invite and I get the
message below:

This message could not be sent. Try sending the message again later, or
contact your network administrator. You do not have sufficient permission to
perform this operation on this object. See the folder contact or your system
administrator. Error is [0x80070005-0x80070005-0x000508].

I also get the following message in my log:

When I create an appointment, it stays for 30 secs then disappears and I get
the following logged:

I have uninstalled Outlook 2003, unistalled Outlook 2007, reinstalled
Outlook 2007, tried renaming the OST, Mapi32, and EMS*32.dll files and
repaired the installation but the same issue appears. I have also tried the
Office Diagnostics.

I can create appointments in the web version on Outlook and they appear and
hold in Outlook 2007.

We use Exchange 2003.

Help please.
