Your quite a ways behind using Windows XP my friend, maybe it's time for an upgrade?
Silly comments like that don't help my fiend, do they?
1: Exchange 2007 is compatible with XP, hence no technical limitations.
2: A technical answer to a question isn't just to tell the user they must upgrade to stay with the times, when they don't need to. There are perfectly valid reasons for using w2k/xp and as operating systems, while they may not be as new as vista/win7/win8, they are miles better in terms of stability and documentation. I still use dos boxes. Does that mean I am behind with the times? No, they do jobs that more modern OS's cannot do as well on the same resources.
Anyway back to jcalder:
I assume you are trying to use exchange 2007 or 2010 from the filename in your posts?
You fail to state what the original error was and what your are trying to do but I hazard a guess at CDO errors because it isnt installed or problems with extracting data out of reports? You need to be more explicit.
However in anticipation of the above perhaps being the case, I googled a helpful page which shows you modification of office and someone has been so kind as to provide a CDO fix as well.
Try reading through that page as it may help you further. If you still cannot resolve it afterwards, please post back but provide as much detail as you can.
