Exchange/Outlook 2007: Slow Searching/Opening Emails

Server: DELL PowerEdge SC1435. (2) AMD Opteron Quad-Core Processors @ 2.30 GHz. 8GB Memory. Windows Server 2008 SP2 64-bit. Exchange 2007 SP2.

Client: DELL Vostro 420. Intel Core 2 Quad 8200 @ 2.33GHz. 3GB Memory. 1Gbit Ethernet Adapter. Windows XP SP3. Outlook 2007. 83,000 emails. 5.8GB mailbox.

When client tries to use the Outlook Search feature, it usually takes up to 5 minutes and Outlook completely freezes.

At around this time, every year, we archive his emails from the previous year (2010) into a local PST file, which frees up and takes most of his emails off the server. But it is still extremely slow, even after we do that each year.

Need help resolving this issue.

How many mailboxes you have on Exchange server. Secondly 5.8GB is pretty huge mailbox. Max 2 GB we should recommed. Secondly are you using cache mode or not.?

Secondly 8 GB is not enough RAM for 2007. I am running server with 32 GB RAM

We have between 50 - 100 mailboxes, and I believe this user is using cached exchange mode.

I will definitely look into the memory issue.

The virtual memory was set to be managed automatically. I will change that over the weekend.

Are you using SAN for Database storage? Secondly, have you excluded the Exchange DB's and other Exchange related folders from OS level AV scanning.

Again if you are using SAN for storage, you need to exclude the Physical path.  You can download the WinOBJ tool from below link for finding the physical path.

We are using the local drives for storage.

We did have the following AV exclusion in place for our Exchange server, however, just in case, I also just included the full path of the DB.

D:\Program Files\Microsoft\Exchange Server\Mailbox\*.*
