It does run slow, but without knowing much about your machine I can't help.
Are you running virus checkers for incoming and outgoing mail (that really
slows things down). Do you have enough RAM (the new MS software wants lots
of memory).
My PC is brand new and meets or exceeds all the recommendations Microsoft
suggests to run full features of Vista Ultimate (e.g. 2 GB RAM, Intel Dual
Core 2 proc., etc.)
It seems that after 2 days Outlook began to function a lot better. I don't
know why, but I think the indexing might have slowed it down. I guess I
didn't expect it to take 2 days.
