Does anyone know why the "+" sign no longer shows up next to the distribution list name when emailing that group. This is happening to one user. He use to see the "sign" so that when he clicks it, it shows everyone in the DL name, but know he no longer has that option. The user is permitted to email that group and the outlook 2010 is not running in cache mode. Any ideas what may have caused this? Nothing has changed on the Exchange side so I believe it has to do with this outlook client.
