I have never run into this problem before I installed Windows XP Pro. Whenever I create and envelope in Microsoft Word 2000, when I click on the address book icon, I get an error message that says I am not currently logged onto Microsoft Exchange. I am able to use the address book at all other times except this one. There is no error number. It just tells me to see my administrator, which I am the Administrator and am always logged on as such. Please help me with this. Exchange has always been a huge pain in the you know what.
