Exchange 2010 Management Role loading slowness

Hello,
I'm new to the company I currently work for and relatively new into IT, and one of the first issues I have noticed here is how incredibly slow Exchange 2010 is when loading.
I'm aware there are numerous topics covering this issue after having done many checks on search engines, however most of them seem to advise going to IE and un-checking the boxes defining Certificate Revocation or other solutions that I haven't found to
be applicable, at least not to my knowledge. I have tried the first suggestion but found this made no difference.
We don't get any error messages when loading but it is generally a little slow, however the issue is where it says "Getting management role information for: domain/user info etc...", at the end of the progress bar. It will sit there for
6 minutes before finally loading and allowing me in. This happens every time you use it also, not just the first time, whether it's on the local machine of anyone in IT or on the server.
I've checked the server's available resources and it seems to be more than enough, although it is a virtual server so I'm not sure whether that changes what the issue could be.
Would anyone be able to help point me in the right direction of what I could be checking for? Sorry if this is a really vague question or I've not provided enough detailed information, but any help would be really appreciated. I'm sure one of the more experienced
members of my new team could take a look but I figured I'd try and make a good impression!
Apologies if this is in the wrong forum section also.
Thanks very much

Hi
Thanks for the reply.
We're on Exchange Server 2010 SP3 (14.03.0158.001), as far as I can tell it's all up to date.
Server specs:
OS - Server 2008 R2 Enterprise, 64bit
RAM - 32GB
Processor - Intel Xeon E5-2690 @ 2.90GZ, 16 Cores, 16 Logical Processors
There's 433 mailboxes in total, spread over 19 databases (a database for each department), 17 of those being mounted and active.
Once I'm into the management console and can use the various features, the performance is generally fine, it's just that initial loading where it hangs.
Thanks

Exchange 2010 - Management Console and Shell Very slow

Heya
I have an Exchange 2010 SP3 enviroment, with 2 HUBCAs and 5 MBX servers.
This servers were 2008 R2 standard, and they were working fine.
This weekend, in order to configure DAG, i upgrade 3 of them to server 2008 R2 enterprise with dsim. Is not the first tiem i do this, and never had problems before.
After the upgrade, the server started fine, the mailboxes, the database.. everything fine.. except, de mmc and the shell.
Both, the mmc and the shell wont start. It gives me the winrm error, but because a time out.
I have installed the installed the iss-winrm feature, delete on regedit and %appdata% the "cache" for the management console, checked the firewal... and nothing worked.
Well, thats not true, in one of the servers, the Management console started working fine, but the shell, it connect, but every command i launch it takes like 10-15 minutes to execute (for example, a get-mailboxdatabase).
In the other,, no the Management console, no the shell connects, i get a winrm timeout.
I dont know were to continue cchecking why happens this, just started after changing the 2008 R2 from standard to enterprise
Thanks for the help!!

Hi,
Please check that your time is in sync as well on your Exchange Server.
Please check whether this issue caused by performance.

Error when trying to install MS Exchange 2010 Management Tools Windows 7 x64 SP1

When I try to install Exchange 2010 Management Tools on my Windows 7 Pro x64. I get the message ExSetupUI.exe has stopped working? Has anybody else gotten this message? It doesn't even load into the install screen. It is stopping before then.

Hi
Have you installed the admin tools for windows 7 and all the prerequisites? Try running the setup from an elevated prompt or "as Administrator"

Forcefully delete user's "Deleted Items" from Exchange 2010 Management shell ?

After migration from Exchange 2003 to 2010 my organization's some user can't delete items from their deleted items folder, it generate a error message so how can I forcefully delete user's deleted items from their "Deleted Items folder" from
Exchange 2010 Management shell ? Thanks
Babu

Hi Babu ,
Based on my knowledge i have given some suggestions please have a look in to it.
1.We cannot use the search-mailbox command specifically for any folder in the mailbox.But we can use it for a whole mailbox.Below is the command which will copy the entire contents of the mailbox to the target folder called as "backup" .
Search-Mailbox -Identity "problematic mailbox name" -TargetMailbox "test mailbox" -TargetFolder "backup" -LogLevel Full -deletecontent
Note : Before executing the above command , please execute the below.
New-ManagementRoleAssignment -Name "Import Export_Enterprise Support" -SecurityGroup "Enterprise Support" -Role "Mailbox Import Export"
Once the above command is executed then you need to add your admin account to the security group "Enterprise Support" and then use the Search-Mailbox command to copy the entire items to the target mailbox and also it will delete all the copied
items from the original mailbox.
2.Another one option is to use the MFCMAPI tool to force delete the items on the deleted items folder.
Most importantly before doing all the above , please share me the error message what your users are facing while deleting the items from deleted items folder.
Thanks & Regards S.Nithyanandham

How other email server (sendmail) will make connection to Exchange 2010 mutli role server.

Hi,
We have 2 Exchange 2010 multi role server and one load balancer for Cas array.
Now we do understand that DAG will be using for database and CAS can be in HA mode via Load balancer.
Now question is, we do have other non-microsoft email server with same smtp address so when this sendmail server will try to make connection to exchange 2010, which server name/ip we need to give them.
Will it be DAG ip/name or do we need to give both server IP.
Amit Rawat | MCITP - Exchange 2007/2010| CCNA |MCSE- 2003| Lync 2010|http://blog.amitrawat.net

you can use whatever Ip's are listening on port 25 on the 2010 hub transports.
If your load balancer is listening on port 25 and balancing that (probably only a https loadbalancer?) you can use that ip.
If not you can put your 2 cas server IP's in the smart host connector from the sendmail box.
It certainly wont be the DAG ip as the mailbox role has nothing to do with the hub transport.
Foremost i don't have separate CAS here, I do have 2 Exchange(cas/HT/MBX) and DAG is configured.
when sendmail send email to Exchange i need to use some common smtp address to point these servers, so that if one goes down sendmail server can still make connection via that common name.
i can not put two name space(since these 2 exchange are HT server as well) for sendmail server. Any suggestion .

Exchange 2010 management tools and others

Win2k8 domain, Exchange 2010 servers
We want to move to Win8.1 but we, the admins, are preventing it because our tools like the Exchange 2010 Management tool doesn't work with Win8.0 so we're stuck with Win7.
I've googled around and most suggestion never worked.
Does Microsoft have any plans at all to have Exchange 2010 management tools and other tools we use to manage our domain work with Win8.1?

Hi Rino,
Thanks for your sharing and efforts put on this issue.
This will benefit others who encounter the similar scenario as yours.

Exchange 2010 Management Pack Data Warehouse Synchronization Fails

Hi Everyone!
Has anyone had success with importing the Exchange 2010 management pack into Service Manager 2012?
When we try to import it, it fails.
Upon further investigation, the 'System Center Core Monitoring' management pack (which is not included with Service Manager 2012) is a dependency of the Exchange 2010 management pack but
after we import it from the OpsMgr 2012 media, we still get the following warning when we import the Exchange 2010 management into Service Manager 2012...
"The management pack was imported successfully.
Warnings (1):
Override verification failed, cannot find Management Pack Element : : Cannot find ManagementPackElement [Type=ManagementPackRule, ID=Microsoft.SystemCenter.Agent.MonitoringHost.PrivateBytesThreshold] in management pack ManagementPack:[Name=Microsoft.SystemCenter.2007,
KeyToken=31bf3856ad364e35, Version=6.0.6246.0]."
...and, the Exchange 2010 management pack status in the Service Manager 2012 Data Warehouse 'Management Pack' view indicates 'failed' after the MPSyncJob completes.
We have a few 'Business Services' which depend on the Exchange 2010 management pack that we are trying to synchronize from OpsMgr 2012 and we are stuck until we can get the Exchange 2010 management
successfully imported into Service Manager 2012 and have it show a status of 'Completed' the Service Manager 2012 Data Warehouse 'Management Pack' view.
Nothing useful in the
Service Manager 2012 Data Warehouse and Management servers events logs that we could see.
Any help or guidance would be GREATLY appreciated!
Regards,
JJ

Update: I Just tested with CU2 installed for SrvMgr 2012 and OpsMgr 2012 and version 14.3.38.2 of the Exchange 2010 management, but the management pack still fails to deploy to the SrvMgr 2012 data warehouse (the management pack status shows
up as 'failed' and the MPSyncJob shows the management pack as 'pending association'). The only clue I have for this problem is the folllowing warning which occurs when I import the management pack into SrvMgr 2012...
I also get the following 33519 Event ID warning in the Operations Manager event log on the data warehouse server...
~~~~~
Management pack association ignored. This does not require any action. If you continue to frequently see this warning, contact your administrator. This process will continue to retry.
Management pack ID: e2296ed5-ddbc-ebc7-3881-c5288adaa7cf
Management pack name: Microsoft.Exchange.2010
Management pack version: 14.3.38.2
Data source name: SRV
Message: Either the MP has failed deployment Or any of its references has failed deployment
~~~~~
Has anyone had success with getting the Exchange 2010 management pack imported and successfully deployed to the SrvMgr 2012 data warehouse?
The good news is that even though the Exchange 2010 management pack has a status of failed, the distributed applications in OpsMgr 2012 that depend on the Exchange management pack now show up under Configuration Items/Business Services including
all related service component objects which was what I was trying to accomplish in the first place, so for now I'll just leave the Exchange 2010 management pack in the data warehouse with a failed status.

JJ

Exchange 2010 Management Console Initialization failed

Hi.
I have a server running 2008R2 as a domain controller with Exchange 2010 aswell.
This is a fairly new migration from a sbs2003 server, which went very well, in regards to exchange and AD.
The management console has worked since the migration, but suddenly today it stopped working, with the following message (the message is actually from the management shell, which isn't working either.):
[dc.domain.local] Connecting to remote server failed with the following error message : The WS-Management service cannot
process the request. The system load quota of 1000 requests per 2 seconds has been exceeded. Send future requests at
a slower rate or raise the system quota. The next request from this user will not be approved for at least 975630592 milliseconds.
For more information, see the about_Remote_Troubleshooting Help topic.
IIS is working, and listening on ports 80 and 443.
All services are running. I have tride to restart IIS, Windows Remote Management, informationstore and system attendant, but still no luck.
I hope you can help me figure this out.

I got it. I had to open IIS7 and create the Default Web Site, as I'd deleted it sometime ago.
Once I did that, everything worked great! Frustrating the things we do that come back and kick us in the face for hours, months later....

Exchange 2010 performance is very slow

Hi Team,
One of our Exchange 2010 server is running very slow,
My problem is when i remote desktop do my Exchange servers, everything is so slow.
Any idea's what could cause this?
Thanks,
Sivakumar Thayumanavan

Hi Jatin,
Please find the answer for your question.
1. Server is virtual or physical - Virtual
2. If virtual then RAM is static or dynamic - Static
3. Is the RDP only slow or when you log on locally also - RDP only slow as the server is virtual server
4. If only RDP and its a Virtual machine then by any chance you have a broadcom lan card..??
what task manager is showing.. can you share the screen shot.

Increase CPUs on Exchange 2010 Mailbox Role

Good Day,
Hi , I have an Exchange 2010 SP2 Mailbox Role Server installed on Windows Server 2008 R2 .
I want to increase the number of CPUs on the Mailbox Server from 1 to 4 , will this affect anything on the Mailbox Server negatively such as failure or else ?
Note that the procedure is :
shut down the sevrer ,
change the CPU numbers ,
start the machine ,
then it will prompt for restart

Should be no issue. I have increased the CPUs on virtual guests a number of times. Just ensure you have enough capacity on the host so the ratio of virtual to logical does not exceed 2:1
Note that 2010 SP2 is no longer supported. You should be at SP3 plus the latest RU.

Unable to connect to Exchange 2010 Management console after - Exchange 2010 SP3 Rollup 7

We have been having issue with our Exchange Server 2010's Transport Service failing due to a database corruption. I was hoping that maybe applying the Roll-up 7 for Exchange might fix this issue, however after applying the patch we are unable to start the

Hi,
Please try the following steps to narrow down the issue:
1. Uninstall and reinstall .NET package in Exchange server.
2. Under location C:\Windows\Microsoft.NET\Framework64\v2.0.50727\CONFIG, took a copy of Machine.Config.default, renam it to Machine.config and copy it under this path again.
3. Do IIS reset by running iisreset from a Command Prompt window.
4. Reboot the server and verify whether the Exchange services are started.

I've seen errors similar to this in these forums, but I haven't had any luck with the steps used to correct other's problems. The most recent steps I've taken are:
uninstalled and reinstalled IIS, then uninstalled and reinstalled CAS, along with various other fixes to no avail.
After installing Exchange and CAS the console was working for a couple of weeks, it died with this error after two things we can remember, although various other things may have been the cause:
1. installed a lengthy list of windows updates
2. installed the URL rewrite module: http://www.iis.net/expand/URLRewrite and set it up to rewrite http://domain to https://domain/owa, this has since been reverted and uninstalled, it still doesn't work.

Issue:
Connecting to remote server failed with the following error message: The WinRM client cannot process the request. It cannot determine the content type of the HTTP response from the destination computer. The content type is absent or invalid. For more information, see the about_Remote_Troubleshooting Help topic.
Possible causes:
1. Remote PowerShell uses Kerberos to authenticate the user connecting. IIS implements this Kerberos authentication method via a native module. In IIS Manager, if you go to the PowerShell Virtual Directory and then look at the Modules, you should see Kerbauth listed as a Native Module, with the dll location pointing to C:\Program Files\Microsoft\Exchange Server\v14\Bin\kerbauth.dll. If the Kerbauth module shows up as a Managed module instead of Native, or if the Kerbauth module has been loaded on the Default Web Site level (instead of, or in addition to, the PowerShell virtual directory), you can experience this issue. To correct this, make sure that the Kerbauth module is not enabled on the Default Web Site, but is only enabled on the PowerShell virtual directory. The entry type of "Local" indicates that the Kerbauth module was enabled directly on this level, and not inherited from a parent.
2. If the WSMan module entry is missing from the global modules section of the C:\Windows\System32\Inetsrv\config\ApplicationHost.config file, as follows:
<globalModules>
<add name="WSMan" image="C:\Windows\system32\wsmsvc.dll" />
This will result in the WSMan module displaying as a Managed module on the PowerShell virtual directory.
To correct this, make sure that the WSMan module has been registered (but not enabled) at the Server level, and has been enabled on the PowerShell virtual directory.
3. If the user that is attempting to connect is not Remote PowerShell enabled. To check if a user is enabled for Remote PowerShell, you need to open the Exchange Management Shell with an account that has been enabled, and run the following query.
(Get-User <username>).RemotePowershellEnabled
This will return a True or False. If the output shows False, the user is not enabled for Remote PowerShell. To enable the user, run the following command.
Set-User <username> -RemotePowerShellEnabled $True

Exchange 2007 management console open slow

Hi all, I have exchange 2007 SP3 + RUP 2 Installed. Recently we have observed that the console is opening very slowly. We have less number of recipients in exchange. We have higher end hardware and enough disk space and memory available Regards, Avinash

Hi Avinash,
Generally opening EMC takes some time to open and its very hard to advise you if there is no error. Meanwhile disable CRL Checking in server could help you.
