Exchange 2010 Console is painfully slow.

We are in a transition phase from Exchange 2007 SP2 to Exchange 2010 SP1. I have update rollup 2 installed on all the servers. What I noticed with 2010 is the Console is extremely slow. When I try to grant something like Manage Full Mailbox Permissions to another mailbox, it starts a search procedure that lasts for over a minute and it looks like it tries to populate every object in the Forest. We have two Domains. Our Forest Root which is pretty much empty and our production Domain which is a child of the Root. I have the Console configured correctly I think as far as the Recipient Scope. I have it set to Global Catalog and View all recipients in the forest. Its pointing to a Domain Controller in our production Domain. I tried the other configuration which is View all recipients in specified organization unit and then selected our production Domain pointing it to a loca Domain Controller and it did not help. Is there some kind of hotfix or update to resolve this?

I believe your Exchange 2010 is lacking system resources. How much RAM does your Exch 2010 box have? With anything less than 4 GB and a weak processor you will see this sort of behaviour.

Fix will be to add more RAM.

The other thing to do is install the Exchange 2010 EMC console onto a workstation with the appropriate rights.  My Exch 2007 console runs slow on the server itself, even though it has 8GB of RAM.  It runs fine on a workstation.  There is an MS article somewhere that explains why this is.

Here is a blog posting by Sembee, explaining that no matter what resources you throw at it the user experience can be poor.  try install the tools on a workstation as per my above post, and this blog post

I'll take a look at that article but I can tell you our Exchange servers have 16 GB of memory and two processors. Its a virtual environment but so is our Exchange 2007 environment we are migrating from and I never had an issue with 2007. It also does the same thing running it from a workstation. There is something different about 2010 and the way it searches the Forest any time you want to change anything. Its also extremely slow launching. Our Help Desk is starting to complain because they see a noticable difference going into the Console and doing anything and they run it from a workstation.

One more thing. This blog is about Exchange 2007. My Exchange 2007 is just fine. Its 2010 that is slow as grass growing.

Did you find anything from working with Microsoft? I've got an Exchange 2010 server on a Dell PowerEdge T610 with 2 quad core Xeons and 16 GB of RAM and only about, but it is painfully slow to work on when logged in via RDP. My backups using ShadowProtect that should take a few seconds, take a few hours to initialize before they can run. It runs great after a reboot, but after about a week, back to slow, so if you learned anything from Microsoft, I'd love to hear it.

Got interrupted in the middle of adding to that and was trying to say server has about 40 mailboxes.

Microsoft just released Update rollup 3 for SP1 which I am installing this weekend. A tech at Microsoft told me it addresses a lot of performance issues. My biggest and only issue is working out of the console and powershell.

Thanks, I'll give the update a try too. I haven't noticed any mailflow or OWA delays, it's just slow to do anything else on the server.

Hi,

We have the same problem of delay here when trying to add some accounts via the Manage Full Access Permissions... Our version is 2010 SP2, not yet updated to Rollup 1.

Cannot find any solution at this time.

Osiexchange, did your call to Microsoft and rollup installation fixed your issue ?

osiexchangeAuthor Commented:
No, I did not call Microsoft on this one. I am at SP1, Update Rollup 6 and the problem of opening the console seems to have gotten better but it still takes a long time to add a user to a mailbox or grant send as permissions. What I have found as a work around is to just hit the Stop button and then type the name and select Find Now. Its not perfect but its faster than just letting it do its thing.

SP2 improves memory usage and performance on Exchange, I would recommend upgrading to that. I would hold off on UR1 for SP2, as users have reported a few issues on the Exchange Team blog.

Thanks. Its on the schedule. We were at rollup 3 and I did not want to make the jump to SP2. Its best in our environment to take little steps.
