Quick Exchange 2010 Perfmon Counter question

So in the following article:
http://technet.microsoft.com/en-us/library/ee832791.aspx
Under the section where it speaks about calculating your IOPS per Mailbox Server is says to track the Perfmon Counter "MSExchange Database ==>
Instances ->Database Maintenance IO Reads/sec" to use in your calculations.
My issue is that I don't see that counter at all when pulling counters from my Exchange 2010 mailbox servers. I have "Database Maintenance
Duration" and "Database Maintenance Pages Bad Checksums" but no "Database Maintenance IO Reads/sec" under "MSExchange
Database ==> Instances"
Am I looking in the wrong spot?
Exchange 2010 SP2

Hi
Sorry, this link was kept in my Favorite years ago, I did not notice it had be removed.
After researching, I found
"It is no longer necessary to pick the correct counters for the Exchange Server Roles that are installed as this script will automatically detect the roles installed and will add the appropriate counters for each role detected."
http://archive.msdn.microsoft.com/ExPerfwiz
So on that link, you can ExPerfWiz, it is a powershell based script to help automate the collection of performance data on Exchange 2007 and Exchange 2010 servers, you can download from here
http://archive.msdn.microsoft.com/ExPerfwiz/Release/ProjectReleases.aspx?ReleaseId=5859
Hope that could help

Exchange 2010 - PerfMon - Messages Queued for Delivery = 2,147,483,649

Our monitoring system is alerting Messages Queued for Delivery as 2 Billion messages and the value returned by PerfMon > MSExchangeTransport Queues > Messages Queued for Delivery also matches this number during some samples.
I was wondering, what's going on here. When checking queues using Get-Queue cmdlet it doesn't show more than couple of messages in the queue.
How do I get this fixed? This seems to be a known issue from thread http://social.technet.microsoft.com/Forums/en-US/ac121f02-4359-4d18-b86a-9c9c78b320a9/perfmon-messages-queued-for-delivery-2147483764?forum=exchange2010
Any assistance would be greatly appreciated.

Hi ChaituNanl,
Thank you for your question.
By our search, I suggest we update Exchange to Exchange 2010 CU6 or later, because problem also seem to appear to Exchange CU5 or former.
We could download the CU by the following link:
http://social.technet.microsoft.com/wiki/contents/articles/240.exchange-server-and-update-rollups-build-numbers.aspx
Notice: please note the version of Exchange Service Pack
If there are any questions regarding this issue, please be free to let me know.
Best Regard,

Exchange 2010 RPC Encyption question

Quick question. We are running Exchange 2010 SP3 RU 5 (latest and greatest). All of our CAS servers have RPC Encryption disabled. If clients are enabled for Encyrption will this encrypt traffic to the CAS servers? Question is we're
seeing issues with some of our Cisco Wan Optimizers. I just want a better understanding if only the client side (Outlook 2007/2010) is enabled does that encrypt.

Hi,
Agree with above opinion, if all cas servers have disabled RPC Encryption, Clients will not be encrypted traffic to the server regardless of whether the client encryption is enabled.
More details refer to the following articles:
RPC Encryption Required
Outlook connection issues with Exchange 2010 mailboxes because of the RPC encryption requirement
In addition,Microsoft strongly recommends you leave the encryption requirement enabled on your server.
Hope this helps!
Thanks.

Database mailbox grow quickly Exchange 2010 SP3

Hello.
Since we migrated from Exchange 2003 to
2010, the growth of our databse mailbox
is excessive. We have a total mailbox
size hovering around 75 GB and the size of
the database is 120 Gb.
Mailbox quotas are very
limited and 90% of users move emails
from mailbox to PST personal folders.
I get the impression that the space freed by removing
emails or move them to PST
is not claimed as White Space
and hence the excessive growth of
the DB.
I have seen that there is a fix to solve this
problem for versions prior to Exchange 2010
SP3 but the current version we have
implemented and it is with SP3.
Any idea to find out what is happening and
how to fix it?
Thanks in advance and best regards.

Hi.
I have reviewed the total size the mailboxes
and Dumpster with the following command:
Get-MailboxDatabase"MailboxDatabase"|Get-MailboxStatistics|SortTotalItemSize-desc|ftdisplayname,TotalItemSize,itemcount,TotalDeletedItemSize
The result is:
•Total Mailbox size(GB)->82,213
•Total Dumpster size(GB)->14,531
•Total ->97,344
The size of the DB using the command:
Get-MailboxDatabase-Status|Sort-ObjectDatabaseSize-Descending|Format-Table
Name,DatabaseSize,AvailableNewMailboxSpace
Is as follows:
Name
DatabaseSize                            AvailableNewMailboxSpace
MailboxDatabase         107.4 GB (115,302,531,072 bytes)        1.438 GB (1,544,486,912 bytes)
The actual disk size occupied
by the MailboxDatabase is->112GB
What else may be using the space in theMailboxDatabase?.
Thanks and regards.

Exchange 2010 SP3 install question

Greetings! I am planning on installing the SP3 update for Exchange 2010 in preparation for a Hybrid deployment with O365. After installing the SP3 update to all Exchange servers in our environment, I was going to then install the RU8 on the servers.
Hopefully I can perform all of this during one maintenance window. I have already performed the schema update for SP3 during our most recent maintenance window.
I have been scouring the forums for any potential upgrade issues. I wanted to know if there was any concern about the RU8 update for SP3 that might affect our environment from past experience of other admins; whether it be Outlook clients (we use mostly
Outlook 2010 with some Outlook 2013) or OWA. We are currently on SP2, RU6.
Thanks in advance!

Hi,
As what Amit mentioned above, you can upgrade from Exchange 2010 SP2 RU6 to SP3 RU8, as long as this version is supported for Hybrid deployment with O365.
http://technet.microsoft.com/en-us/library/bb629560(v=exchg.141).aspx
To DAGs, please consider the following conditions:
Upgrade passive servers first. Place server in maintenance mode if any monitoring applications are in use. Stop any scheduled tasks or other processes running on the DAG member or within that DAG that could adversely affected the DAG member being upgraded
or the upgrade process.

Exchange 2010 SP3 Rollup Update 6

Our Exchange environment is currently on Exchange 2010 SP3 RU3 and the Forefront Protection 2010 for Exchange server version is 11.0.713.0 (Rollup 3).
We planning to upgrade Exchange servers and install Exchange 2010 SP3 RU6, question which I have is it Mandatory to upgrade the Forefront Protection 2010 for Exchange server version is 11.0.727.0 (Rollup 4) before we install Exchange 2010 SP3 RU6 on the
Exchange servers.
Thanks,
AJ

Thanks Adam for the prompt response and yes I recall these cmdlets to disable and there is a similar cmdlet to enable it. Also after Exchange 2010 SP2 after some RU there is no need to disable FPE before installing RU however it is recommended to disable
it.
If you refer the comments section mentioned in the blog below it talks about it:-
http://blogs.technet.com/b/exchange/archive/2014/05/27/released-update-rollup-6-for-exchange-2010-service-pack-3.aspx
If you read the comment posted by James Knoch posted on this blog which is as below,
SP3 & the Rollup Updates are not supposed to require you to disable Forefront anymore, but it doesn't hurt to be safe and disable/enable it anyways. Make sure you are running Forefront Rollup 4 (http://support.microsoft.com/kb/2619883)
& the latest security update (http://www.microsoft.com/en-us/download/details.aspx?id=41836).
Above stated confused me a bit, is it mandatory to upgrade Forefront or it is NOT.
Thanks,
AJ

Exhcange 2003 to Exchange 2013 Through Exchange 2010

Hello everyone and thanks for your help in advance. I have been tasked with the upgrade of an exchange 2003 server to Exchange 2013. After reviewing the lack of upgrade paths directly to 2013, I think the best path would be to transition through
2010. The domain controller is also 2003. If I understand the process correctly, I should join the new Exchange box to the current domain. Then install Exchange 2010. My questions are:
1. Is installation as simple as the way I described?
2. After installation, is there a way to port the Exchange data from the old machine to the new machine without taking down the Exchange 2003 machine?
Unfortunately, I have only a very basic understanding of Exchange, so I need to take this in small steps. Any help would be appreciated.

Hi Kmcnet,
Base on my experience , if only a small number of mailboxes, the most convenient way is to export/import PST files.
I recommend you consider using the following method to upgrade the exchange to 2013:
1.Export all the users mailbox contents into a PST since its only 35 users
2.After you confirm the exported pst are fine remove the exchange 2003 server
3.Install Exchange 2013 in your environment and create new mailboxes for 35 users
4.Import the pst to their new mailboxes

Exchange 2010 MSExchange Replication ReplayQueueLength via perfmon incorrect..

If I look at my ReplayQueueLength via perfmon it shows a constant value of 2,147,483,649. If I look via Exchange Management Shell using "Get-mailboxdatabase | get-mailboxdatabasecopystatus" it shows a more believable answer..
My suspicion is that perfmon is incorrect. I've seen this in our Exchange 2007 environment as well, which had the full SCOM monitoring on it, and would cause an alarm in our SCOM environment falsely...
Anyone have any thoughts on why these values get off? Bug?
P.S. IN the Select a Forum section below there is no Exchange 2010 topics to pick but it forces me to pick one.
Jason Meyer

Trying below should below:
a.) Open the Exchange Management Shell.
b.)Type add-pssnapin Microsoft.Exchange.Management.PowerShell.Setup and hit enter.
c.) Type remove-perfcounters –definitionfilename "E:\Program Files\Microsoft\Exchange Server\Bin\perf\AMD64\eseperf.xml" and hit enter.
To reload performance counters for ESE, perform the following steps
a.) Close down any running versions of Performance Monitor and stop any other monitoring services that might be attempting to use those counters
b.) Open the Exchange Management Shell.
c.) Type add-pssnapin Microsoft.Exchange.Management.PowerShell.Setup and hit enter.
Type new-perfcounters –definitionfilename "%ExchnageInstallPath%\Bin\perf\AMD64\eseperf.xml" and hit enter.
if it still doesn't get the value back to normal even after folliowing the process enclosed above, active the copy of that database in question on another server and fail back.

Upgrade From Exchange 2010 SP1 to SP3 - Schema Upgrade Question

Hello,
We're currently running Exchange 2010 SP1 in our environment and want to upgrade to SP3. I just had a couple of questions related to preparing AD for this new SP that I was hoping that someone could answer.
Setup
We have a single forest with two domains within it (A and B for example). The schema master is in Domain A but this domain doesn't contain any Exchange 2010 servers. Domain B contains our 2010 CAS and Mailbox servers.
Both domains have Windows 2003 SP2 domain controllers.
I understand that before I proceed with the upgrade to SP3, I first need to update the AD schema on our schema master. I was planning on doing the following :
Log onto an existing Windows 2008 R2 64 bit "member" server in domain A (containing the schema master) with an account which is a member of the Schema Admins and Enterprise Admins groups.
Run SETUP.EXE /PrepareAD.
Do I need to also run SETUP.EXE /PrepareDomain on domain A as well or does the /PrepareAD sort this out ?
I was then going to turn my attention to domain B (which contains the 2010 CAS and Mailbox servers) and do the following :
Log onto an existing Windows 2008 R2 64 bit 2010 Mailbox server with an account which is a member of the Domain Admins and Enterprise Admins groups.
Run SETUP.EXE /PrepareDomain
Is this the correct procedure to follow ? I assume that I can then go ahead and start to upgrade the Exchange 2010 SP1 servers in the following sequence :
CAS\HUB Server(s)
Mailbox Server(s).
Clarification on the AD upgrade steps would be appreciated.
Thanks
Mark

This has all the info you need:

Prepare Active Directory and Domains

Upgrade Exchange 2010 to Exchange 2010 SP1, Exchange 2010 SP2, or Exchange 2010 SP3
Note: There is no harm in simply running setup/PrepareAllDomains.
You should break out each Prep step since you have multiple domains:
setup/PrepareSchema
setup /PrepareAD
setup /PrepareAllDomains
you can run all of these from the same DC you run the setup/PrepareSchema step!

Questions about upgrading from Exchange 2010 RTM to Exchange 2010 Service Pack 3

I am preparing to perform an maintenance upgrade on our current Exchange 2010 Server, to Service Pack 3 (and any post-SP3 roll ups), but I have a couple questions about the process.
Current Exchange Server details:
Exchange 2010 Standard
Version: 14.0 (Build 639.21) - from Exchange Management Console
Version: 14.0.702.4000 - from Outook client
Active Directory forest and domain levels: Windows 2008 R2 native
The questions I have are:
1. Can I assume that because it's version 10.0.702.4000 I am on Exchange Server 2010 RTM Update Rollup 4?
2. Can Exchange 2010 Standard RTM be patched directly to Service Pack 3, or would I need to perform incremental patches (i.e. SP1, SP2, etc.) before going to SP3?
3. Do I need to manually perform the AD domain schema prep before applying Service Pack 3, or will the Service Pack 3 update process automatically handle the modifications of the AD schema?

Hi,
Here are my answers you can refer to:
1. Firstly, I’d like to explain , we can use connection status to check our Exchange server version from Outlook client:
http://office.microsoft.com/en-in/outlook-help/determine-the-version-of-microsoft-exchange-server-my-account-connects-to-HA010117038.aspx
And I check my version from both EMC and Outlook client. It’s same.
2. We can directly update RTM version to SP3 , and the update will take an additional 30 minutes or longer per database.
3. Since Exchange 2010 SP3 makes updates to the Active Directory schema, we need prepare AD domain schema. However, it will automatically prepare AD and the domain when you install the update.
For more information, you can refer to the following article:
http://technet.microsoft.com/en-us/library/jj965774(v=exchg.141).aspx
If you have any question, please feel free to let me know.

Exchange 2010 to 2013 Migration Question

Hi Folks,
This is where I'm at: We have 2 Exchange 2010 servers (both multi role) and I was given 4 VM's for exchange 2013. I just completed installing Exchange on the four 2013 VM's (2 dedicated CAS and 2 dedicated MBX) and applied SP1. I documented all
of the 2010 server config info (i.e. all the URL's for the namespaces, etc). We have a hardware NLB and a MacAfee host in the DMZ where all inbound/outbound email routes to check for AV/Spam. My question is, what are my next steps that
take place so that I'm truly in co-existence mode? I'm assuming I want to make the 2013 servers primary now so that all mail routes to/from them and all client connections are made to them? Could someone point me in the right direction maybe
to an article on what my next steps are? I want to get everything cut over while in co-existence so that I can start moving mailboxes. Thanks a lot !

Questions about migrating Exchange 2010 to 2013

We currently have two Exchange 2010 servers with roles separated. One local mailbox server without CAS in our building and a CAS with no mailboxes in a remote datacenter.
We plan to migrate to 2013 with two new servers hosting all roles on each and then shut down the 2010 servers. There will be one local and one in a datacenter for Exchange 2013 so that either server could be individually restarted without internal LAN users
losing email access. (We do not want to open network access from the Internet to the onsite CAS). Is it practical to set it up this way?
How do we get the existing certificates (mail, autodiscover, and the local host name etc.) moved from the 2010 to the 2013 to the new servers when I assume they both must be running side by side for at least a short time while mailboxes are moved form 2010
to 2013? Will we need to buy new SSL certificates since the local host machine names for the Exchange server 2013 servers will be new and there will be more than one CAS?

Most of the CAs allow issuing duplicate certificate (as if you are requesting for a new cert) for the servers running same application. If your CA doesn't provide duplicates you can export the certificate and import to Exchange2013. http://msexchangeguru.com/2013/06/29/import-cert-e2013/
In certificate you dont need your internal FQDN. Especially in future you wont be able to add your internal FQDN in your certificate as most of the CAs wont allow you to add internal FQDN.
When you migrate to exchange 2013 you just need to configure the external URLs of Ex2010 in Ex2013 for both (i.e. same URLs for internal and external URLs) and point your common name and autodiscover to Exc2013 as Ex2013 will proxy the requests to your legacy
Ex2010 server. i.e. Your client interface will be Ex2013.
Please check this it will help you configure Split DNS and configure your URLs
http://exchange.sembee.info/2013/install/clientaccesshostnames.asp
http://www.mustbegeek.com/configure-external-and-internal-url-in-exchange-2013/ GUI
Configure split DNS to resolve external name from internal network.
Keep both Ex2010 CAS and Ex2013 CAS servers till all get logged in atleast once to connect to Ex2013 mailbox automatically.
As your DAG stretched across the data centers make sure
your DAG is in DAC mode.
http://technet.microsoft.com/en-us/library/dd979790(v=exchg.150).aspx
Please read this as well for details about DAG configured in multiple site
http://technet.microsoft.com/en-us/library/dd638129(v=exchg.150).aspx
Ensure you use Exchange2013 SP1 as it is already released and available for download
http://www.microsoft.com/en-us/download/details.aspx?id=41994
Do you have a load balancer in place?
Regarding internet facing it depends. You can configure CAS2013 server in DMZ if you wish to.

Exchange 2010 Service Pack 3 question

Forum,
We currently have a small Exchange organization consisting of one Exchange 2010 SP1 server at the corporate office and a 2nd server (mailbox) at another location. The other location also has a CAS server. We need to apply SP3 to Exchange and
have already performed the schema update for SP3.
My question is: are we able to install SP3 on the corporate Exchange server
now and apply SP3 to the remote CAS and mailbox servers later without causing any Exchange Organization issues? Server downtime at the corporate office is easier to schedule than the remote location which needs change
control notification and planning well in advance as they operate 24/7.
I just don't want to upgrade one server then cause problems throughout the Organization as Exchange is heavily used. We need to upgrade to SP3 not only because it is the latest SP that resolves a host of issues but also to prepare for
a hybrid deployment of Office 365.
Thank you in advance,
Joe

You would want to update CAS servers first, prior to any mailbox servers.
Is the single Exchange server in the corporate office multi-role?
Do you have a DAG between the two mailbox servers going over the WAN connection?

I'm having users report intermittent Outlook slowness 2007. I can't repeat the issue exactly but I have seen it -- you get a message that says "Outlook is trying to retrieve data from <Exchange Server>" and it takes it a noticeable
amount of time. One of the difficulties in troubleshooting this is that I haven't seen it on my own machine, nor can I find the way to replicate the issue consistantly.
We actually just upgraded from Exchange 2003 to Exchange 2010 and never had these issues in the past.   I've run a process monitor on the server (which is about 8 times better than our old Exchange 2003 server - 2 quad-core procs and 12 GB of
RAM for about 250 mailboxes) and find nothing abnormal in terms of CPU time or network bandwidth usage (4 teamed 1 GB/s connections). I have also monitored several of the Exchange RPC items, and Client: RPCs but Client:RPCs does not return anything
at all (just 0 the whole time).   Are there other things I should be looking at with PerfMon?
I'm at a point where I'm not sure where to take my troubleshooting. Does anyone have any ideas? The fact that I (and most other users I've asked) never experience the issue leads me to believe that it might have something to do with a
local computer issue rather than a server issue, but I'm hearing reports from people with both Outlook 2007 and Outlook 2010. The other somewhat common thread is that
Outlook is NOT running in cached exchange mode, but it wasn't when we were on the 2003 server either and we did not have this issue.   Our Exchange 2010 Server is now running the new UM role, however, and we were using Cisco Unity before.
I have already disabled all Outlook add-ins and disabled anti-virus (client, but not Nod32 for Exchange).
Thanks, any ideas would be appreciated.

Forgot you're using 2010, the item counts are much more laxed, 100,000 per folder compared to 5000 in Exchange 2007. For your Outlook 2007 clients, can you confirm you're up to date on the last post hotfixes as of Feb 2011? Also I would disable caching
of shared calendars in outlook. Also note that outlook 2010 caches all shared mailboxes by default.
Turn off calendar caching. If you have Exchange in use then Outlook 2007 may well have the caching of people’s calendars turned on. This means that when you open a calendar you have to wait for the cache to populate, which can slow
things down a bit sometimes. To do this:
Go to the Tools Menu and select Account Settings
Select your Exchange Account and press the change button
Press the more settings button
Select the 2nd tab (Advanced)
Un-tick the “Download shared folders” option. Note that this will stop cached Sharepoint folders from downloading into Outlook as well.
Press OK until all options are saved.
