I have a question about Outlook. All of our users who use Outlook versions newer than 2000 (XP and 2003) all have the same problem. They get this message "Task 'Microsoft Exchange Server' reported error (0x8004010F) : 'The operation failed. An object could not be found" every couple of minutes. Users who use older versions of Outlook do not have this problem. All of a sudden this problem occured, and about a month ago the problem was suddenly gone, but last week users started to get this message again. Email does go out and comes in without any problem, but this message keeps appearing on the screen. What could be wrong? We use Exchange 5.5 on a Windows NT4 server (SP6).
