(sorry for the cross-post but I posted this in the Outlook forum and no takers...) Our desktop guy is on leave and I am having the hardest time with this! Someone has made a change to the outlook.prf file we've deployed on the network (it was an approved change but no one caught a typo in it) and now when our users use our newprof.exe tool, they get a blank empty set of .pst files instead of being pointed to our Exchange server. I wanted to edit the outlook.prf to get the users' profile set up--- I don't care right now about mass deployment and would be content with something I can paste to the user's C drive on-demand. I'm just having a real hard time getting this file tweaked properly. Could someone please point out for me how to edit this file so that the Exchange server is set to the default service, the server name is given, and the user's mailbox name/alias equals his/her login ID? Thanks a ton--- I really appreciate it!
