Exchange 2010 SP3 - Can DAG member be on OS 2012 R2 STD?

Hi guys.
We have Exchange 2010 SP3 on 2008 r2 enterprise.
now we are thinking about having DAG. I know that recommendations is to have the same OS on 2nd Exchange server but still is it possible to make DAG between: Exchange 2010 SP3 on 2008 r2 enterprise and on other side Exchange 2010 SP3 on 2012 R2 STD?
with best regards,
bostjanc
No. It wont let you do that.
http://technet.microsoft.com/en-us/library/dd638104(v=exchg.141).aspx
DAGs are available in both Exchange 2010 Standard Edition and Exchange 2010 Enterprise Edition. In addition, a DAG can contain a mix of servers running Exchange 2010 Standard Edition and Exchange 2010 Enterprise Edition.
Each member of the DAG must also be running the same operating system. Exchange 2010 is supported on both the Windows Server 2008 and Windows Server 2008 R2 operating systems. All members of a DAG must run either Windows Server 2008 or Windows Server 2008
R2. They can't contain a combination of both Windows Server 2008 and Windows Server 2008 R2.
In addition to meeting the prerequisites for installing Exchange 2010, there are operating system requirements that must be met. DAGs use Windows Failover Clustering technology, and as a result, they require the Enterprise version of Windows.

Exchange 2010 Decommisioning a DAG member from a 3 node Dag

Hi Guys,
What the safest way to remove one server from a 3 Node Dag.
Currently I am planning the following steps:-
Remove Exchange server MAIL03 from DAG
1.Start up Exchange Management Console
2.Go to Organization Configuration > Mailbox > Database Management;
3.if mail boxes are mounted on MAIL03, Select the database where ” Mounted on Server” reads the MAIL03;
3.1.Select Move Active Mailbox Database;
3.2.Select the Mailbox server i.e. MAIL01\MAIL02 to host the mailbox database copy and select Move;
5.When the move has finished, select the database copy hosted on the MAIL03 in the lower pane. There, select Remove.
6.Remove the MAIL03 server from the DAG. Select tab Database Availability Groups;
7.Select the DAG the MAL03 server is a member of and select Manage Database Availability Group Membership;
8.Select the server and click the red cross to remove it from the list. Click Manage to proceed with the actual removal;
9.When finished the mailbox server is no longer member of the DAG.
10.Rebalance Mailbox Databases in DAG.
What do you guys recommend?
Also after the removal of the DAG node, what the best way to reduce the Passive Database/Transaction logs? our current setup is as follows:-
I want to remove the drives L,M,N,O
Thanks
Jitinder

Hello,
Based on your description.
If you want to remove drives only from that server and leave databases working on the rest of nodes:
1. Remove database copy on that server.
2. Remove drives.
It is not required to move mailboxes from these databases. In this scenario you will not be able to re-add copy of these databases because all nodes need to have the same drive
letters.
If you want to remove L, M, N, O from all servers:
1. Move mailboxes from these databases.
2. Remove them (copies and empty dabatabes).
3. Remove drives.
There is no need to remove server from DAG if you just want to remove database copy from one node.
Hope it helps,
Adam

Exchange 2010 SP3 RU5 on 2012 r2 - yei or nei

Guys, one question:
On this link:
http://technet.microsoft.com/en-us/library/ff728623(v=exchg.150).aspx
I see that Exchange 2010 SP3 with RU5 is not supported on 2012 r2 and is only supported on 2012 server.
One dumb question: But what if you have 2012 r2 domain controller, can you put exchange 2010 sp3 ru5 there?
bostjanc

Ok, but even if that worked for you it doesn't mean that it is supported (because its not) and it wouldn't be a good idea to put that server in production. If your plan is to stay on Exchange 2010, then you should install it on a supported OS.

[SOLVED] Can't add a node to the cluster with error (Exchange 2010 SP3 DAG Windows Server 2012)

Hi there!
I have a problem which makes me very angry already :)
I have two servers Exchange 2010 SP3 with MB role started on Windows Server 2012. I decided to create a DAG.
I have created the prestaged AD object for the cluster called msc-co-exc-01c, assigned necessary permissions and disabled it. Allowed through the Windows Firewall traffic between nodes and prepared the File Share Witness server.
Then I have tried to add nodes. The first node has been added successfully, but the second node doesn't want to be added :). Now I can add only one node to the DAG. I tried to add different servers first, but only the first one was added.
LOGS on the second nodes:
Application Log

UPD:
when Exchange servers ran on the same Hyper-V node, the DAG is working well, but if I move one of VM to another node, It stops working.
I have installed Wireshark and captured trafic of cluster interface. When DAG members on the same HV-node, there is inbound and outbound traffic on the cluster interface, but if I move one of DAG member to another node, in Wireshark I see only outbound traffic
on both nodes.
It's confused me, because there is normal connectivity between these DAG members through the main interface.
Please, help me if you can.

Exchange 2010 SP3 DAG Flip Flop File Share Witness Issue

Hi All,
We are facing one strange issue with Exchange 2010 SP3.
Our environment is as below
a single DAG spanned accross 2 AD sites with 6 MBX server.
Each site have 3 MBx server.
File Share Witness is on Hub server in primary site.
Note: The DAG IP is from Primary DC VLAN and which cant be streched accross DC due to network restrictions/limitations.
It was working fine till date.
But, yesterday onwards we are facing issue.
All DB dismounted and DAG name disappear from EMC and while doing refresh its giving error as below
Exception type: Microsoft.Exchange.Data.DataValidationException
Exception message: Could not convert property WitnessServer to type UncFileSharePath. Error while converting string 'vesthub700.mydomain.com\DAG1.mydomain.com' to result type Microsoft.Exchange.Data.UncFileSharePath: "vesthub700.mydomain.com\DAG1.mydomain.com"
is not an acceptable path. You must use an absolute, local, long file path, that doesn't contain '~', or a UNC path. Parameter name: path
We are not able to execute any cmdlets related to databaseavailabilitygroup from EMS and its giving same error.
Failover Cluster DAG resource is Flip/Flip continuously.
Its only become stable after reboot of the hub server holding FSW and the 1st mailbox server.(Cluster Owner)
We are even not able to move cluster group to different server.
Performed ExBPA no such issues found which related to DAG.
Performed clsuter validation.
Only generic cluster events in Mailbox servers.
Observation:
Its only become stabe if we remove the msExchFileShareWitness Value for DAG1 using ADSIEdit.
And the problem recurs if we set it back again.
Any help or suggestion is appreciated.
Thanks,
soumen

Hi Belinda,
Thanks! I have checked the Mailbox Server Application Log and found few 2155 Event Id generated at the time of the issue occured.
Process Microsoft.Exchange.ServiceHost.exe () (PID=9312). Configuration object CN=DAG1,CN=Database Availability Groups,CN=Exchange Administrative Group (FYDIBOHF23SPDLT),CN=Administrative Groups,CN=xxxxxx,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=mydomain,DC=com
read from DCTDK35.mydomain.com failed validation. DataValidationException will be thrown. Set event logging level for Validation category to Expert to get additional events about each failure.
One update is that the DAG is stable now after we set an alternate FSW last night.
Regarding the 2nd IP assignment for DAG for the 2nd subnet, we have gone through technet and other sites which refering to add the same from EMC or EMS.
Is it sufficinet to simply adding the 2nd IP to DAG from EMC or EMS? Or do we need to take any other special consideration.
Also, adding another IP it will create one more IP address resource to Failover Cluster, but I belive at a time both the IP wont be online. Do we need to keep it offline manually or its automatically taken care by Exchange.
Please suggest.
Also, regarding executing the CollectOverMetrics.ps1 we are following
http://www.msexchange.org/articles-tutorials/exchange-server-2010/monitoring-operations/monitor-dag-database-failover.html
but failed to execute. Can you suggest the correct parameter.

Exchange 2010 SP3 DAG Witness/Quorom Server Placement with 3 Datacenters

Hi we have 2 Exchange 2010 SP3 Server in the same Organization in a DAG
First one in Datacenter 1 in Germany
Second one in Datacenter 2 in Austria
There is a Third Datacenter available in Switzerland
Where should we place the Witness Server?
Our major concern is not a WAN Link will go down, most time a Datacenter will loose Power for some hours due
maintenance work or other things.
Is it a good idea to place the Witness Server in the third Datacenter!?
We found a Document which some missconception which talks about placing the witness always in
the primary Datacenter. But the Datacenter Switchover Document for Exchange 2013 says use a third Datacenter.
Is that also okay for Exchange 2010 or are they totally different?
Thank you in advance
Troga

Hi,
It is a new configuration option in Exchange 2013 that we use a third location for hosting the witness server.
Placing FSW in the third location will privide the ability automatically failover databases to the other datacenter in response to a datacenter-level failure event.
For more details, you can look at the "Witness server placement considerations" section in the following article.

Exchange 2010 SP3 - How many Calendar Items/Folders can you create under "all public folder"

Hi,
Is there a limitation on how many calendar items/folders you can create under "all public folder" in Exchange 2010 SP3?
Thank you

I don't believe you can create calendar items under the root folder, but it's been so long since I worked with a system that had public folders that I'm not sure. If you mean "a folder that can contain calendar items", that is not a calendar
item itself.
Now, I believe your underlying question is, "How many folders can be created at the root level of the public folder hierarchy?" If so, there is no simple limit that I know of (you can have thousands, if you really want), but management gets
pretty unruly with the more that you have. I normally recommend that you create sub-folders to logically meet your requirements, then have each of these with more folders (normally that only specific groups of users will be able to access or add items
to). And anyone will tell you that you want to restrict anyone from creating their own folders at the root level. In fact, this is the default setting for a new Exchange 2010 installation.
I'll add that you really should stop trying to use public folders, since there are newer technologies (SharePoint, for instance) that work much better and are much easier to use.

MS Exchange 2010 Sp3 Ent Migration to Exchange 2013

Hello,
We currently have 2 Exchange 2010 SP3 servers in 1 DAG. Both servers host CAS, Mailbox and Hub Role.
I want to introduce a 3rd Exchange 2013 Server and slowly move users onto a new DAG I build in Exchange 2013.
Can I create a 3rd Exchange 2013 Server with CAS and Mailbox Server Role and make the 3rd Exchange server (2013) a member of the existing (2010) CAS array then slowly perform local move requests for users mailboxes
from my Exchange 2010 DAG to the Exchange 2013 DAG without any disruption to my outlook, OWA and AS clients?
Exchange 2010 (Windows 2008 R2)
Exchange 2013 (Windows 2012 R2 DataCenter)

Hi,
In Exchange 2013, all Outlook connectivity (Internal and External) takes place over Outlook Anywhere(RPC/HTTP). Thus, CAS array which is used internal for RPC/TCP protocol (MAPI) no longer exists in Exchange 2013.
For your coexistence environment and the plan to migrate all mailboxes to Exchange 2013 in the future,
we need to set all virtual directories for CAS 2013 and enable Outlook Anywhere for Exchange 2010. If the mailbox is moved to Exchange 2013, the Outlook client would connect to the server which is set in Outlook Anywhere External host name
and Internal host name instead of CAS array. If all configurations are proper, CAS 2013 would also proxy the service requests for Exchange 2010 users.
Here are some reference about Client Connectivity in an Exchange 2013 Coexistence Environment:

We recently had users reporting unable to open items in OWA. Issue is confirmed across all CAS servers.
Issue started while on Exchange 2010 SP3 UR8v2, we upgraded to Exchange Server 2010 SP3 UR9 during troubleshooting.
3 AD Site DAG, multi-role servers
So far we have done the following to troubleshoot:
* Check security propagation for account permissions.
* Check security on all virtual directories.
* Check permissions on web.config
* Re-run PrepareAD
* Uninstall and reinstall CAS role
Please review the errors below and let me know if you have any words of wisdom on this issue. Thanks!

Hi Noel,
Base on my search, it may be due to IRM feature been enabled for OWA.
I recommend you use the following command to check if the value of IRMEnabled parameter is true:
Get-OWAVirtualDirectory – Identity “servername\owa (default web site)” |FL name,IRMEnabled
If the value is true, you can use "Set-OWAVirtualDirectory" cmdlt to change it to false, and check if any helps.

Exchange 2010 SP1 Update Rollup 6 to Exchange 2010 SP3

Hi there,
I am planning to install Exchange 2010 SP3 next week and after reading some of the related comments on this site I got a little worried.
Our current Exchange environment consists of the following:
1 x CAS/HT Server
2 x Mailbox Server (members of a DAG)
The OS of the 3 servers is Windows Server 2008 R2 SP1. All servers are running Exchange 2010 SP1 Update Rollup 6.
The Execution Policies on our Exchange servers are set as follows:
– CAS/HT Server:
Scope ExecutionPolicy
MachinePolicy Undefined
UserPolicy Undefined
Process Undefined
CurrentUser Undefined
LocalMachine Unrestricted
– Mailbox Servers:
Scope ExecutionPolicy
MachinePolicy Undefined
UserPolicy Undefined
Process Undefined
CurrentUser Undefined
LocalMachine RemoteSigned
Please note that we do not have any Group Policies that defined the PowerShell script execution policy.
I would be very grateful if you (or any of the kind readers) could help me with following questions:
1- Do I have to change the execution policy on our Exchange servers before installing SP3? If I have to change a policy, what should I change? And how would you recommend I should do this?
2- After installing SP3 on a server, can I install the latest rollup update on this server before moving to the next server? For example, can I do the following:
i. Install SP3 followed by RU 5 on the CAS/HT server -> Apply the our custom settings
ii. Install SP3 followed by RU 5 on the first mailbox server
iii. Install SP3 followed by RU 5 on the second mailbox server
Many thanks,
M

Hi Amit,
Many thanks for the swift reply.
That's correct. We didn't set the Powershell execution policy via Group Policy. We only configured the execution policy of "LocalMachine" to "Unrestricted" on the CAS/HT server using the "Set-ExecutionPolicy" command on the server.
The mailbox servers' execution policies have not been changed and are set to those values by default.
I must admit, I go event more confused when I read the "http://support.microsoft.com/kb/2668686" and "http://support.microsoft.com/kb/2810617" articles.
But it looks like I shouldn't worry as our current Powershell execution policies shouldn't affect the upgrade. Right?

Exchange 2010 SP3 and UR6 Query - Order of Install

hi,
I need to update my Exchange 2010 SP2 Servers to SP3 and Update Rollup 6.
Can someone confirm the update order for me?
I have 5 servers;
Live Data Centre:
2 x HUB / CAB (Using Windows NLB)
2 x Mailbox (DAG)
Disaster Recovery:
1 x Multi-Role Server (CAS / HUB and Mailbox) - this is also Part of the DAG
Two Questions:
1.) What is the Order in which I install SP3 on these Servers? Should it be Live Data Centre: HUB / CAS, Mailbox Servers and THEN the Multi-Role Server at DR?
2.) When Upgrading each server, should I do SP3, reboot, check and THEN install Update Rollup 6 - or should I upgrade all Servers to SP3 and then start the process again to get to Update Rollup 6?
Thanks in advance for your help with this query.
Regards,
Adam

1) Internet facing CAS first in each AD site. Order: CAS> HUB> UM> MBX
2) Personally, I would install SP3, reboot, then install SP6, but its really up to you.

Exchange 2010 SP3 install

Hi,
I am running with Exchange 2010 SP1 in DAG & CAS/HUB in cluster mode. need to upgrade to SP3. few things need to know
1. Schema upgrade will be done I as read in the article. can this create any issue? what is the best measure to safeguard any problems of schema upgrade. Do we do this along with exchange setup or we should run schema upgrade prior to install exchange 2010
SP3?
2. Any impact on active sync, outlook anywhere & HUB connectors side post SP3?
3. Do we need to take any exchange related backups as we are running mailbox, CAS/HUB servers in redundant mode?
Please share your experiences.
Regards,
VIpin

Hello,
1. It is a good practice to run schema updates before launching Exchange update. You should also make backups of your domain controllers before any schema updates because these
particular changes cannot be rolled back easily.
3. Yes, you should have backups (tested!) of your Exchange servers. Server's redundancy (DAG's, CAS Arrays etc) doesn't protect your servers if the update fails.
Hope it helps,

Moving to a new CAS box exchange 2010 sp3 ru6

I am entertaining the idea of creating a second CAS box for our environment.
in the current environment
we have:
All servers have Exchange 2010 sp3 RU6
Ex1 (physical box) - have HUB/Transport/DAG with Ex2
Ex2 (physical box) - have HUB/Transport/DAG with Ex1
CAS1 (VM on hyper v 2008r2 cluster) - Client access role
outlook 2010 profiles all point to cas1
what I want to achieve is to build a cas2 box on a new hyper cluster. we v have a hyper v 2012r2 cluster that has a different ip scheme (cas1 ip is 12.12.100.x, and cas2 would have 12.12.103.x)
what would I need to do in order to get my users to point to the new cas box. downtime is not a major issue. but I want to make sure that if I build cas2, it would prevent cas1 from working and users getting mail. I am sadly unfamilure
because I did not set up the ex1/2 or the cas box. I have only ever installed SPs and RUs.
I have no existing CAS Array.
I would happy to read any setup docs, or anything of that nature if you have links available.
let me know what you can, and feel free to ask any further questions if you have need of additional info.
thanks
Ian
Ian

Hi,
You need to install CAS2 in existing exchange environment and need to move\change URLs OWA,EWS,Autodiscover , ActiveSync, outlookanywhere, OAB , SSL certifcates and your DNS IPs to point new CAS2.

Install Exchange 2010 Sp3 on Windows 2012 R2

Dear All,
From Microsoft Exchange support matrix, I can tell that Exchange 2010 Sp3 is not listed on supported page. However when I run the setup, the prerequisite setup check, dose not list any warnings or issues with the setup, all check are green. Is it possible
that the support OS matrix has not been updated? Is Exchange 2010 Sp3 supported on Windows 2012 R2?

Thank you

The prerequisite check is checking that the required Windows components are installed. Exchange 2010 is still not supported on Windows Server 2012 R2.

Sharepoint 2013 vs Exchange 2010 SP3 search (Error while crawling LOB contents)

Hi there:
We are trying to solve the problem: ERROR CRAWLING LOB CONTENTS when we wish to search Exchange 2010 SP3 public folder content on Sharepoint 2013 Foundation.
Quick briefing:
Followed this instructions:
http://technet.microsoft.com/en-us/library/jj591608(v=office.15).aspx
* Created CRAWL RULE
- Used Domain Admin for content access ---> IS THIS WRONG?
- Domain Admin can access public folder thru Outlook Web Access (checked)
- Included all items in this path
PRINTSCREEN 1
* Added a content source for Exchange Server public folders
- Logged to Outlook Web Access with domain admin, expanded Public folders and opened 1st subfolder in new window and copied the address
- Logged to Outlook Web Access with domain admin, expanded Public folders and opened 2nd subfolder in new window and copied the address
PRINTSCREEN2
* Did a FULL CRAWL
PROBLEM:
- Search results does not throw "correct data". Some items are not being found
CRAWL LOG is reporting: Error while crawling LOB contents
Detailed error message:

Try again later.; SearchID = 4E8542D3-48EF-404E-8025-8D9AAEFE777A )
We thought it's a throttling issue / found possible solution:

Tried it, still same Error messages, problem not resolved.
Any hints? Please advise.
With best regards

Hi Bostjan,
From the error message, the issue might be caused by throttling policy on Exchange side. And the article you posted provides the right solution, some modification to the solution and please try again.
For throttling policy part
1.Execute the command for Set-ThrottlingPolicy
Set-ThrottlingPolicy SharePoint -RCAMaxConcurrency Unlimited -EWSMaxConcurrency Unlimited -EWSMaxSubscriptions Unlimited -CPAMaxConcurrency Unlimited -EwsCutoffBalance Unlimited -EwsMaxBurst Unlimited -EwsRechargeRate Unlimited
2.Execute the command Get-ThrottlingPolicy SharePoint to double confirm the policy setting has been successfully executed
For registry key part
1. Start Registry Editor (regedit).
2. Navigate to the following registry subkey:
\\HKEY_LOCAL_MACHINE \SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem
3. Right-click ParametersSystem, point to New, and then click Key.
A new key is created in the console tree.
4. Rename the key MaxObjsPerMapiSession, and then press Enter.
5. Right-click MaxObjsPerMapiSession, point to New, and then click DWORD (32-bit) Value.
The new value is created in the result pane.
6. Rename the key to <Object_type>, where <Object_type> is the name of the registry object type that you're modifying. For example, to modify the number of messages that can be opened, use objtMessage. Press Enter.
7. Right-click the newly created key, and then click Modify.
8. In the Value data box, type the number of objects that you want to limit this entry to, and then click OK. For example, type 350 to increase the value for the object.
9. Restart the Microsoft Exchange Information Store service.
If it still doesn’t help, please check ULS log for related error message.
