Hi, Are other users experiencing the same issue? Whether this issue can be reproduced? Was any error message received in the Event Log on the Exchange server side? If not, please try to recreate Outlook profile to check this issue. Thanks Allen

Hi Allen, Many users are experiencing this issue. All the users are using Outlook 2007 and we are using Exchange 2003 server. I will try to re-create the new outlook profile and see at least if it resolve at my end. Keep you posted. Thanks Ravi
