Hello,I have a client with 30,000 Exchange 2007 mailboxes.When they go to the Mailbox recipients pane using the EMC and try to open the properties of a mailbox, there can be a delay of almost a minute before the information is returned to it. Subsequent access to the same account properties does not have a delay even after the EMC is restarted.For accounts that never had their property pages accessed before, what they see is the property page itself comes up quickly but none of the fields are populated for a while.Again this only happens on first access with mailbox recipients. This is not a critical matter whatsoever but any resolution or explanation would be very much appreciated in order to maintain customer confidence in going to Exchange 2007.

are yuo trying to access the recipient property page from Mail box server or from some other server which has managment console installed on it? Try to access the same from HUB or CAS server and see the result.Raj

Hi, Can you please check to verify the Domain Controller/Scope of recipient in EMC -> Recipient Configuration -> Select "Modify Recipient Scope" in Context menu or Action pane and check if it querying any remote DC? if so then Please select any local GC/DC. By default it is set to ask the local DC/GC. Thanks. Vishal Ramnani | MCITP - Exchange 2007 | MCSE Messaging | MCTS - Win 2008 Config

That's how the EMC behaves with even only 1.000 mailboxes. Never seen the issue you describe with the properties sheet, though: "property page itself comes up quickly but none of the fields are populated for a while." But can very well imagine this to happen with 30.000 mailboxes.There appears to be some common consensus (which also corresponds to our experience) that the console sometimes is very slow to start, but when it is running, there are no performance issues. See for instance Simon Butler (Exchange MVP) EMC 2007 - slowhttp://www.petri.co.il/forums/showthread.php?t=26868 On Windows 2008 I usually disconnect an RDP session thereby keeping the EMC open, instead of logging off. This does not prevent other administrators from logging on to the server.In order to give your customer an"explanation ... to maintain customer confidence in going to Exchange 2007," you could also tell that the EMC is a graphical front-end to PowerShell.The EMCoffers discoverability and ease of access, but no real bulk management or automation. That's where PowerShell comes in. While the EMC is very good designed, one of the real strengths of Exchange 2007/2010 is administration with PowerShell. jas

HI,Some time lack of hardware might effects for Exchange 2007 GUI performance. You might experience you will able to get better performance after second time. So please check memory utilization of that particular server. Please read below Msexchangeteam article i have attached. That mentioned some tricks and tips to enhance Exchange management GUI.Resources Exchange 2007 console tips and tricksregards Chinthaka Shameera | MCITP: EA | MCSE: M | http://howtoexchange.wordpress.com/

Thank you all for your input. I think Jas's post demonstrates that this delay does exist in other environments.However no suggestion has worked to change this delay.Raj: The client has the EMC on 2 Hubs, 4 CAS, 10 MBX, and two standalone managment servers. The up-to-one-minute delay on opening mailbox properties for the very first time happens consistently per server.Vishal: I changed thescope from entire forest to the root domain and got the same delay. I also limited the search to 10 itms instead of 1000 and still got the delay.Chinthaka: Hardware performance should not be in question across 18 physical servers. The memory utilstays high but that seems by design for Exchange 2007. The servers themselves are all running at least 16GB of RAM.I guess my goal here is to see if anyone with 10K mailboxes are seeing the properties populate with a delay as well. If not then maybe it is the EMC navigating in a muti-domain environment or just the operations coded for it to do this task in a large environment.Can anyone confirm or negate this?Deelow

We've got approximately 5000 objects. There is a slight delay while loading them... probably about 7 to 10 seconds depending on the server. I realize we're not as big a shop as you're looking for, but the delay seems fairly consistent(you're client is 6x larger than us whichwould equal42 to 60 seconds). Hope this helps.

I have checked couple of servers with almost 6 to 7K mbx and there is a delay in opening the recipeint properties. Is this normal with MMC 3.0???Raj
