Memory Usage in Outlook 2010 Technical Preview

It’s been about a day now since installing Office 2010, and this is one thing I noticed earlier today which is excellent.

In Outlook, I have two email accounts: An Exchange account connected with RPC over HTTPS and a POP3 account. I’ve got one OST file for the Exchange mailbox, one PST file where all the POP3 email goes and a PST for backing up old emails to.

Outlook 2007 used to run in the region 0f 100,000 KB to 150,000 KB according to what I was doing that day. As you will see from the screenshot below, Outlook 2010 is running as a measly 47,736 KB. That’s less than one of my Internet Explorer tabs.


Excellent work Office team.
