Some of my users outlook just stops working. Emails wont come in neither will it go out. I have exchange 2010 and exchange 2003 in co-existence. I have to close outlook and open again for it to start working. The other thing to get it working is to enter the password. There is a small icon at the right hand side in outlook that says about authentication. I have one send connector and one receive connector. Emails come in and go out as normal.
I would like to know what i can do to fix this problem permanently as it happens to users randomly. last weeke it happened to about 5 users.
