Strange! I do not why it sudden happen. It was working last week.
My machine is installed MOC 2007 to connect to OCS2007. It is connected but appear "Cannot Synchronize Address Book". Further check, only affected to Distribution Group. I search one of Distribution Group, it found then I add in my contact list. It appears on my contact list, but showing "Distribution Group service cannot be performed this action..."
I use my colleague computer and logon to my account. It is perfectly working well. I tried other machine also the same, it is working fine. Except my own machine cannot.
I uninstalled MOC2007, and reinstall it. It is the same.
Please advice.
Try looking in the %appdata%\Local\Microsoft\
If this doesn't work next steps would be providing us with the full distribution group error message you are receiving plus any associated Events from your machine's event logs. Would also be helpful to know if you are using either of Enterprise Voice or Remote Call Control, and if yes - which one?
Finally, do some direct verification of your Address list service; Right click the pool name in question in the OCS management console, choose 'Properties' -> 'Web Component Properties'. Go to the "Group Expansion" tab and take note of the internal and external URLs. Verify that they are both functioning and accessible from the workstations in question by opening the URLs in a web browser (you should see something like the attached screenshot (ExpansionService.jpg)).
Is there anything else about the failing workstations that is distinct - for instance are they on a different network segment from the functioning ones?
Cheers.
