Hello, This morning some of our users reported that their Global address list was missing, I looked at the address list properties in Outlook and it was pointing to one of our Global catalog servers, now when I look to a system that was not experiencing the problem I notes that their Global address list was pointing to a different Global catalog server. Also if I run Outlook.exe /resetfolders in the PCs that are experiencing the problems their global address list appears but if they close outlook and open again the Global address list is gone. Any ideas why this is happening, Thanks Juan Rosas List Charter and FAQ at: http://www.sunbelt-software.com/exchange_list_charter.htm List Charter and FAQ at: http://www.sunbelt-software.com/exchange_list_charter.htm
