My client currently has two user profiles: one for him and one for his wife, and also two separate email accounts, again, one for him and one for his wife. However, he wants to delete one account so they can all use one user profile (don't ask me why!). Is there a way to have two accounts on the same page in Outlook 2003? (for example, one account at the top of the Outlook sidebar, one below it?)

I don't know Outlook that well, as I don't use it, but it's funny you mention this because I've heard of people in the past having problems with their Outlook account because of it being tied to the user profile. The whole program seems to have too many technical issues to me for being a simple email.

I agree. With every release MS say they make things easier, but to me they don't. I use Thunderbird, but unfortunately, most of my clients use Outlook

Well, that does sound like MS's mo, saying the next version is going to revolutionary! Even when it's the same thing with a new face and more bugs, maybe a couple features that no one wants..haha I looked around a bit and found a little guide to setting up multiple accounts in Outlook, I don't know if it's exactly what your looking for, but it seemed to me to be a good guide and accomplish what your clients want. It's worth a look: How to setup outlook with Multiple E-mail accounts
Hope that helps!
