Since the latest Zimbra update (see the client information below) we are experiencing problems with the GAT.
Client Version: 6.0.6_GA_2324.RHEL5_64
Client Release: 20100406133038
Build Date: 20100406-1342
When a user inputs an e-mail address or name of a person on the webmail client that is in the GAT, no e-mail addresses and/or names are displayed.
The weird thing is that not all users are experiencing this problem. Both Firefox, IE6,7,8 & Google Chrome suffer from this problem. Another weird thing is that only some addresses in the GAT won't be displayed.
Are you experiencing this problem too, you need more info or you have a solution, please post it below!
