Unable to Expand Distribution Groups

Unable to Expand Distribution Groups

I've had this issue a couple time but for different reasons.  The most simple thing to try if there are no errors on the server is to go to the local box running communicator and go to c:\docs and settings\username\local settings\application data\microsoft\communicator\ and delete the galcontacts.db then go into the sip_user@domain.com and delete everything in there.  Make sure communicator is closed.  After that try logging in again and see if that fixes it.If not go to the server and open the OCS console.  Expand standard Edition Servers and right click the server.  Go to properties then web component properties.  Click on group expansion and see if the check box is enabled.  If it is, highlight and copy the internal URL and paste it into a web browser.  Click on expanddistribution lists.  Type the email address of a mail enabled distro and click invoke.  If group expansion is truly working, then it should return some output on your screen with members and email addresses.
If you are still having issues, check simple things like service accounts for the Application pool LSGroupExpAppPool in IIS.  The default install of OCS creates an account called RTCComponentService.  Make sure that account is in the identity tab of the pool and with the correct password.  Anyway, hope this helps.
