We have a mix of Outlook 2003, 2007 and 2010 clients in our organization.
Users with an outlook 2010 client are having issues with a number (not all) of our distribution lists.
Issues: When selecting a distribution list in the new message 'to' fiedl, a 'message tip' appears with the name of the DL and 'contains xx recipients'.
However, when attempting to expand the DL (selecting the + sign) the following prompt appears "Cannot perfrom the requested operation. The command selected is not valid for this recipient. The operation failed"
When selecting the DL through the outlook address book the memberlist is empty and has a mail tip "unable to connect to retrieve additional data".
The DL's were all created in a 2003 environment.
We are currently setting up a 2010 environment, and all DL's were created prior to any schema updates etc.
Of note, users experience the issue, but access the list through OWA don't have the issue.
