I'm stuck trying to figure out how (if possible) to force the default address book setting to all users. ie. what I want is for all my users to get the same Address book when they open Outlook, rather than the standard Global Address List. This can be done locally for each user but surely there must be a way to do it for everyone! Please help...!

Don't know if this will help you or not because I'm not familiar with exchange but here's how I do it in Win98 or Win2k. Go to the server and use Windows Explorer or whatever to set up a folder off the root directory called Shared Address Book or whatever you want. Again using Explorer, right click on this folder and set it to be shared. Set permissions according to your security policy. Go to control panel, open folder options, and set the options to show hidden folders. Adjust the time and date on the computer to a date a few days forward from the current date (this will be clear in a minute). Close the control panel. Open Outlook and add a new dummy entry to the default address book. Close Outlook. Now search for files that have been modified as of the forward date you set your computer to. You are looking for a file called outlook.pst or similar that contains the address book info for that workstation (it's a DAT file as I remember). Delete this file. When you open Outlook again, you should get an error message saying that it cant find its' address book file and giving you a dialog box to provide the location of the file. You want to provide a shared file for that purpose so navigate through the dialog box to the shared folder on the server and create a file called outlook.pst there if your computer doesn't already do so. If you already have an address book with a lot of info, you need to locate it via the method outlined above and copy it into the shared folder you just set up. Close the window. Close any other remaining open windows. Open Outlook again and enter a dummy address book entry that is clearly recognizable as such to you. Repeat these steps on each workstation with the exception of creating the dummy address book entry. If you've done everything correctly, Outlook should be pointing to the shared folder for its' address book info and you should be able to verify that by seeing your "dummy" address. If so, you've accomplished your mission! Do some final housecleaning (dont forget to set the computer's date back) and set the folder options back to default if you want to, and you should be finished. I don't know any other way to do it. There might be but this works great for me. Good luck.
