What people are saying about the new update:

“I installed it earlier today and can attest to a much snappier performance so I highly recommend all Outlook users apply this patch.”

“Whoah! It is faster! And that's just the startup!”


“My .ost file is 2.5 GB, since applying the patch I've noticed considerable improvements...”


“I downloaded it and tried it out. The change was dramatic: Outlook now starts up markedly faster, and all operations with messages -- opening, moving, deleting, previewing -- are far speedier than they used to be. If you're running O2K7, go get it.”


“It used to take my Outlook ~15 seconds to startup and be in a usable state. Now, after the patch, it came up in 4 seconds. This is a highly recommended fix, so make sure to grab it ASAP!”


“Wow... it almost feels like Outlook 2003!”
