Please ensure that presence is disabled in Outlook. That makes a huge difference.
Otherwise, look at your latency (hold down the control key, right-click on Outlook in the systray, and select Connection Status...). For mail, "avg. response" should be at or below 100 ms. If directory goes higher, that's OK. Regards, Michael B. Smith Consultant and Exchange MVP http://TheEssentialExchange.com From: David Lum [mailto:david....@nwea.org] Sent: Friday, March 25, 2011 12:37 PM To: MS-Exchange Admin Issues Subject: Mitigating outsourced Exchange performance We recently outsourced Exchange (we're at 400+ users) and are adjusting to the responsiveness difference. For those that have outsourced, what kinds of things have you guys done to improve the performance? In our main office of ~250 employees we have 75+MBps download/upload speed (yes we're blessed with a big pipe). Issues reported: 1) Big lags (45 seconds+ ) on loading others' calendars to view, especially if scheduling a meeting with 5+ others 2) E-mail sits in the outbox for minutes 3) Minutes for an e-mail to come in The joyous part is it's not 100% across-the-board like this for everyone. I'm working on narrowing down if there's a common theme of thousands of messages in their inbox, dozens of inbox folders, etc. I found this LINK<http://blogs.technet.com/b/exchange/archive/2007/12/17/3404552.aspx> which looks helpful but would like to hear your guys' opinions as well.
