@SXC; I have thought about running IMAP on both accounts. However, as I often have a lot of emails the loading time of IMAP would be inconvenient. I also wish to have perfect sync between the n900 and my PC.

@Dirty Harry; I wish to sync my outlook email (local PC) with my nokia n900 device. I haven't been able to find a way to do so. However, I noticed it is available with other smart phones. I was wondering if it was available with the n900.
