We recently moved to Outlook 2007; Exchange 2007. On my personal workstation, I am regularly getting messages that include the comment: "Your server administrator has limited the number of items you can open simultaneously." This appears in conjunction with Event ID 9646 on the server. (Mapi Session .. exceeded the maximum of 250 objects of type "objtMessage".) This tends to occur right after the comptuer has "woken up", and it requires no more than Outlook open, with one message. I generally see this with reminders: "Cannot turn off the reminder", but I also get this with email. Exchange is Version 8.1 (Build 240.6) (2007 sp1 +critical / security updates); Outlook is 2007(12.0.6514.500) SP2 (12.0.6535.5002); Windows XP SP3. I have seen a few articles on this, but the recommendations are: a) require unlimiting the number of RPC connections allowed at the server end, b) require modifying the registry on every client workstation, and c) imply that Outlook 2007 is not closing RPC connections. Workstation logs (application, Outlook; Office) indicate nothing other than the connection with exchange was lost & restored: I presume due to the hibernation state temporarily shutting down the LAN connection. Does anyone know if Exchange 2007 SP2 resolves this issue, or how this can be resolved before the sh*+ hits the fan? References: a) http://support.microsoft.com/default.aspx?scid=kb;EN-US;842022 refers to error 9646 on 2003. I assume a similar solution exists for 2007, but could blow out the server if a few thousand users hit it simultainously. If I have to implement it across the board, how do I do so to all users? (Can I point my sms admin to a package?) b) http://support.microsoft.com/kb/953807 : we are at sp2 allready, but are we going to have to run reg2pol and push out registry changes on a continuing and rolling basis? c) See Dr. Google, or Mr. Bing to check on this...

You're probably running some sort of desktop indexing software that's trying to index your mailbox. If that's so, disable the software and see if the problem goes away. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

Hi am2o, It is alway suggest you to install the latest service pack and rollup. Exchange 2007 sp3 has also been released. http://www.microsoft.com/downloads/details.aspx?FamilyID=1687160b-634a-43cb-a65a-f355cff0afa6&displaylang=en About your question, you may forus on the error "objtMessage". The Event ID 9646 indicate if a MAPI client opens more than the maximum number of server objects. More information: An Exchange 2007 Server Stops Responding to a MAPI Client http://technet.microsoft.com/en-us/library/bb676486(EXCHG.80).aspx And if GUID is in the Event 9646, you can refer to this post: http://social.technet.microsoft.com/Forums/en-US/exchangesvradmin/thread/f62cee3e-6669-41de-8223-dd5940de0305Frank Wang

Hi am2o, How about your question? Any updates?Frank Wang

Unless I got the Windows Search installed on my workstation, I do not beleive that I have any indexing software outside of what is in WinXPSP3. Reviewing add/remove programs: I have no obvious search indexers (eg: nothing with search, or index, or assistant in the title is isntalled, and allmost all of the updates have the words: Hotfix, Critical, or Security in them. (the exceptions are KB955839, 973815, 967715)

At this point, we are at SP1 update rollup 10. Going to SP2, or 3 is a good idea, but will take two months to imlement: (eg: Get permission for a schema change across a 12 domain forest 1 month, Install SP3 - another months: it's a management thing, we're working on it. Probably try to put it into 1 project instead of 2). I'm aware of Event ID 9646, however increasing the number of objitMessage allowed could have severe reprecussions across the orginization. To quote the caution from the link provided: "When you increase the maximum number of an object type, you also increase the memory that may be consumed by all client requests connecting to the server. Incorrectly configuring this value could lead to out-of-memory warnings or virtual memory fragmentation warnings. " but thank you for pointing me to the Exchange 2007 version of this article. In this case, the GUID is me - but I think it put me in by name: However the commandlet "get-mailbox -ResultSize unlimited | where {$_.ExchangeGuid -eq "a33236c3-14cc-4e8f-99da-cff05c84ecc4"}" from leeowens337 on http://social.technet.microsoft.com/Forums/en-US/exchangesvradmin/thread/f62cee3e-6669-41de-8223-dd5940de0305 is awesome.

Not really, I'm getting distracted on URLs not appearing a hyperlinks in email now. (automated systems send as plain text. IN 2003, they showed as Hyperlinks. In 2007 they don't. We suspect that they are getting converted between the 2003 front-end servers and the Hub Transport Servers. In Outlook, Tools -> Trust Center: Email Security -> Read all standard mail in plain text. Is unchecked. Also, Tools -> Options -> Mail Format -> editor Options -> proofing -> Autocorrect options -> Tab Autoformat: has Internet and network paths with hyperlinks checked under "replace") What has been diagnosed: The "your Server Administrator..." message only appears when Outlook 2007 is left on when the computer goes to sleep. Closing and restarting Outlook 2007 "resolves" the issue, but it's a bloody stupid workaround.

I.e. the ones that are added as "additional" mailboxes. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

None, I have my inbox, and am attached to no others. Although I have 3 favorite public folders that I never look at.

If you remove the public folders from the "Favorites" does that change the symptoms? Are you working in cached-mode or online-mode with Outlook? Do the symptoms change is you switch modes? Are there any 3rd-party add-ins in Outlook? If you start outlook from "Start | Run" with "outlook.exe /safe", does it change the symptoms? --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

I have not seen any similar errors since I put my workstation in cached mode. I have had to make this a lower priority, as some of our automated systems are sending plain text emails where the URLs no longer appear as clickable hyperlinks.
