I have seen this before. If the user is in cached mode, either click Send and
Receive to get updated security information, or take them out of cached mode,
connect to the share, then put them back in cached mode.

We are running MS Exchange Server 2003 and have 3 clients using Outlook 2007.
Sharing between all 3 were successful (for each pairing) except for one
unable to share with another:

Client 1 can share with Client 2
Client 1 can share with Cliient 3
Client 2 can share with Client 1
Client 2 can share with Client 3
Client 3 care share with Client 1
Client 3 can NOT share with Client 2

The point is only one of these fails with the Mircosoft Office Outlook
message:

"Calendar sharing is not available with the following entries because of
permission settings on your network....Do you want to send them a copy of
this calendar in an e-mail message instead?"

The server administrator swears all permissions between the 3 are identical
including groups they belong to. I've checked permissions within Outlook and
confirmed they were set up correctly. I had someone else double check in
case I just missed something. All to no avail.

Can anyone shed light on what the possibilities are for why this error is
occurring, where to look???

Thanks.
