You didn;t mention if they had the FW option enabled. If so does the issue occur in adaptive mode?
You could check the properties for the Free/Busy options, if they have specified a url to a web server for publishing the info, can you ping the url?
You can also try to enable the option for unsupported protocols, some traffic to/from Outlook could be getting dropped. KB66899
If it only occurs when IPS module is enabled, does it occur when outlook.exe is excluded from the Application Protection list?
Yes, FW was enabled. The URL is available from non-HIPS protected computers. I will look into the KB article you cite and the App Protection list. We are new to HIPS so unsure of all the ins-outs of the application yet. The documentation does not seem really detailed on troubleshooting. Any suggestions on good HIPS troubleshooting methodologies? Where to look in HIPS logs, etc?
Thanks for the feedback.

Excellent list of resources! Thanks!
We found out the issue happened to be with the user account and not the client computer or HIPS. But still thanks for the information. This is very useful!
1. Unable to launch Oultook 2007 (Vista) signature when HOST IPS is enabled. When we disable HOST IPS, signature configuration tab comes up.
2. Unable to launch Outlook Out of office Assistance - Outlook 2003/2007 Out Of Office Assistant 'command not available'
Troubleshooting - checked for HKEY_CURRENT_USER\SOFTWARE\MICROSOFT\OFFICE\11.0\OUTLOOK\Resiliency
which was not there on Vista or XP Pro (07office and 03 office)
Also looked at disabled items on Vista - did not see outex.dll as being disabled.
It was there on Outlook 2003 - I enabled it and the Out of Office Assistant launches. Must be missing something with Oultook 2007...
