Migrate from Exchange Server 2010 sp3 to 2013 sp1

I have one Exchange Server 2010 SP3 server (300 mailboxes) installed on Windows Server 2008 R2 SP1 with three major roles on it (CAS, MB and HT) - typical installation. Edge Transport server is not installed thus for controlling of mail flow
Symantec Messaging Gateway Virtual Appliance is used as Smart Host. UM server is not installed either. I set up test domain environment where I installed one domain controller (Windows Server 2008 R2 SP1) and one Exchange Server 2010 SP3 (Windows
Server 2008 R2 SP1) at first place and yesterday I did everything necessary to install Exchange Server 2013 SP1 on new test virtual server running Windows Server 2012 R2 which I successfully did.
Now in test domain I have two Exchange Servers (2010 SP3 and 2013 SP1). Is there any 100% reliable documentation with all actions that had to be taken in order to successfully migrate Exchange Server 2010 SP3 to 2013 SP1? I would want to know what
needs to be done not only for my scenario but also for other scenarios (DAG, CAS array, Edge, UM, multiple HT servers . . .) since I am interested in digging deep into Exchange Server 2013.

Hi BoxiKG,
In addition to the above mentioned, and this for your reference:

Migration from Exchange server 2010 to Exchange server 2013

Hi All,
We have migrate Exchange Server 2010 to Exchange Server 2013. When I turned off my Exchange Server 2010, Outlook is not able to connect through Exchange 2013. It's prompting for user name and password again and again and nothing would happen
after provide user name and password. So, we are not able to uninstall exchange 2010 from old server.

Run these commands and post the update.

Exchange Server 2010 SP3 test environment - email flow to/from internet

Today I set up test environment for Exchange Server 2010 SP3 - domain controller running Windows Server 2008 R2 SP1, Exchange Server 2010 SP3 on Windows Server 2008 R2 SP1 and client computer running Windows 7 Pro SP1 x64 with Outlook Pro 2010 x64. These
machines are VMs on vSphere 5.0 cluster made of 4 esxi 5.0 hosts.
I have three years of experience in working with Exchange Server 2010 in my production environment but until recently I have not had enough resources to build a test environment. Does "testing" Exchange Server 2010 infrastructure have
a real life purpose considering the fact that only internal email flow is possible since authoritative SMTP accepted domain is not hosted anywhere thus not visible to outside world. This limited email flow combined with absence of possibility to test
ActiveSync, Outlook Anywhere, OWA from WAN, . . . really hurt and make Exchange Server rare technology that can not be tested completely before introducing something new into the production. Services that are not possible to test from the outside world are
useless and whole point of Exchange-like technologies is availability from anywhere and from whatever device.

I set up Internet Send Connector (by default this type of send connector uses DNS MX records to route email automatically). Having sent an email to my gmail account I did not receive it and in transport logs I saw that mx record was found successfully
but there is the following line:
2014-08-05T20:39:51.942Z,Internet Connector,08D17F000FE36010,1,,2a00:1450:4013:c01::1b:25,*,,"Failed to connect. Error Code: 10051, Error Message: A socket operation was attempted to an unreachable network 2a00:1450:4013:c01::1b:25"
I tried also to send an email to my production email address (we have Symantec Messaging Gateway which is used as a smart host (antispam,antimalware,content filter appliance)) but then error is:
2014-08-05T20:50:08.395Z,Internet Connector,08D17F000FE36019,1,,91.238.7.10:25,*,,"Failed to connect. Error Code: 10061, Error Message: No connection could be made because the target machine actively refused it 91.238.7.10:25"
Telnet from test exchange to 91.238.7.10 on port 25 also is not working.

Upgrade directly from Exchange Server 2010 SP1 to Exchange Server 2010 SP3

Hi,
We have current setup with Exchange Server 2010 SP1 ( DAG & CAS Array with WNLB).
Can we upgrade directly from Exchange Server 2010 SP1 to
Exchange Server 2010 SP3 . ?
Thanks in Advanced.
Regards,Ali

Hi Ali,
Yes, you can. Please upgrade your Exchange 2010 SP1 server roles in the following order: Client Access, Hub Transport, Unified Messaging, Mailbox, Edge Transport. What's more, please note that when you install a Service Pack or update rollup on a server
that's a DAG member, several services will be stopped during the installation, including all Exchange services and the Windows Cluster service.
For more information, here is a helpful article for your reference.

Problems installing Mailbox role on Exchange Server 2010 SP3

I am in the process of installing Exchange Server 2010 SP3 on a Windows Server 2012 server in order to migrate our existing Exchange 2003 server. Everything went well with the installation process until I went to add the Mailbox server role, which is giving

Error 87 -with these details below - and a fix. The situation that got me here by the way was an incomplete install that was uninstalled, then installed again.

I found I could fix this by removing the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\eventlog\Microsoft-Exchange-Troubleshooters/Operational
and everything underneath it.
My guess is that wevtutil didn't like adding an event log where it already existed but was slightly different in setup (no idea how, exactly).
After 24 hours I'll try post again - giving things time to make sure they are actually working.

Exchange Server 2010 SP3 Databases are not mounting after the recovery process

Hi,
We are using Exchange server 2010 SP3 in our office. Databases are stored in an ISCSI drive mapped with the exchange. We are taking daily full backup of my Exchange server using Symantec Backup exe 2012. As a testing purpose I created a test environment
same like my existing live environment to check the disaster recovery and backup. Thankfully disaster recovery worked well and I am able to open the exchange management console and powershell. But I am not able to mount the recovered databases ending
with an error saying "Couldn't mount the database that you specified. Specified database: officialrecover; Error code:
An Active Manager operation failed.........." and even I am not able to use the utility eseutil.exe to the database with an error "access to source database failed with jet error 1811". I am able to create a new database and mount
it.
I am using Windows Server Ent 2008 R2 64 Bit with Exchange Server 2010 SP3 in the Live environment with 3 partitions called C (279 GB), E (4.46 TB, ISCSI), F (976 GB) in my Live environment.
For test it is Windows Server Ent 2008 R2 64 Bit with Exchange Server 2010 SP3 with 3 partitions C (240 GB), E (1.4 TB), & F (240 GB).
Please help me with your valid comments to solve and mount the database and close the issue for ever.
With Regards
Jay

Jared is correct that in essence the message is saying the DB cannot be found.
When you restored to your recovery server are all the paths the same, i.e. if the DB existed on E:\XYZ on the production server it must be the same on the recovery server
When you restored into the recovery site do you have AD restored into that site as well?
For the recovery server are you using iSCSI storage for it as well? If so am I correct to assume that you have copies of the databases just for use on this server and are not trying to reference the same instance of the DB from the production
and test/recovery server?
I have also seen an issue where DB's getting written to disk from Symantec mess up the header of the DB. If you want to validate that the DB is actually intact and accessible you might want to check out our DigiScope product
http://www.lucid8.com/product/digiscope.asp using a free DEMO license. If it works i.e. you are able to mount in DigiScope from same location where its failing on the recovery server we know the
DB your pointing at is good and accessible from the current path but something else is amiss in your configuration
Search, Recover, & Extract Mailboxes, Folders, & Email Items from Offline Exchange Mailbox and Public Folder EDB's and Live Exchange Servers or Import/Migrate direct from Offline EDB to Any Production Exchange Server, even cross version i.e. 2003 -->
2007 --> 2010 --> 2013 with Lucid8's

Exchange Server 2010 SP3 Installation with UM Language Pack Error

Hi All,
Kindly help me in this issue, When I Install Exchange Server 2010 SP3, I faced an error in UM role setup as the below,
and when i searched on it i found solution like "Download the UM language packs and tried to install directly" so i downloaded "UMLanguagePack.en-US" from the below URL:
http://www.microsoft.com/en-eg/download/details.aspx?id=36769
and when i tried to install it, i faced the below error:
also i searched on this error and i found solution in registry as the below:
Try remove registry key for the above error :
"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Exchange\<Your Version >\UnifiedMessagingRole\LanguagePacks"
and after i did it, i found first error be solved and the second error still the same as the below:
Error:
A Setup failure previously occurred while installing the UnifiedMessaging role. Either run Setup again for just
this role, or remove the role using Control Panel.
Is there a solution on this issue please i wanna solve it As soon as possible?
Thanks in advance,

I solved the below error by editing in registry:
Error:
A Setup failure previously occurred while installing the UnifiedMessaging role. Either run Setup again for just this role, or remove the role using Control Panel.
Solution:
Open regedit (Start -> run), navigate to the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ExchangeServer\v14
Under each role, UnifiedMessagingRole, have a look for an action and watermark entry, Delete these 2 keys, and retry. it solve this error, and You can now run the installation again of your "UMLanguagePack.en-US". and its done and installed now.
After "UMLanguagePack.en-US" Installation, i tried to continue installation of Exchange Server 2010 SP3, but I faced the same first error in UM role setup as the below,
What can i Do? please help urgently.

NLB detected duplicate cluster subnets - Exchange Server 2010 SP3 CU5

Hi All,
I will explain the environment first, there are:
-Two HUB/CAS servers (WNLB)
--HUBCAS01
--HUBCAS02
-Two Mailbox servers (Failover Clustering)
--MAILBOX01
--MAILBOX02
*All servers are updated to Exchange Server 2010 SP3 CU5.
The issue is that from recently outlook users are disconnecting from the outlook and cannot be joined to the exchange server unless if I drainstop or stop HUBCAS01. Furthermore, if I start HUBCAS01 from WNLB it will work fine for sometimes yet it will randomly
disconnects outlook users from exchange again (For ex: next day morning).
So far when I search deeper in Event log, there is an warning event log:
Event ID 18: NLB cluster [192.168.*.*]: NLB detected duplicate cluster subnets. This may be due to network partitioning, which prevents NLB heartbeats of one or more hosts from reaching the other cluster hosts. Although NLB operations have resumed properly,
please investigate the cause of the network partitioning.
Now I hope you will provide this link to resolve this issue - http://technet.microsoft.com/en-us/library/cc726421(v=ws.10).aspx
But I don't think that this will resolve this issue, as i have tried this for 3 times, yet no luck. Please help me to resolve this issue permanently. Thanks in advance.

Hi,
The issue is mainly related to the HUBCAS01 server. To deep investigate the issue, you need to take RPCTrace from the Outlook client and see the details. Even more, it’s better
to take a Network trace to check the details of the network.
Thanks,

Exchange server 2010 SP3 CPU consumption keep growing

Hi,
I'm using an Exchange server 2010 SP3 14.3.123.4 version.
We are currently experiencing CPU consumption growth on this server.
It appears that the msexchangerepl process could be a good candidate for this CPU overconsumption.
Any clue for this issue.

Hi,
In your posting, the MSExchangeRepl.exe process keeps increasing on the server. The Microsoft Exchange Replication service provides replication functionality for mailbox databases on Mailbox servers in a database availability group. Please check whether
there is any back up program in your Exchange server. Also confirm if there is any Anti-virus program installed in your Exchange server.
In Event Viewer, please check the event log for the MSExchangeRepl source and collect any further information for troubleshooting.

Exchange Server 2010 SP3 RU 8v2 & ActiveSync Device Quarantined Emails

Hi there,
We are using Exchange Server 2010 SP3 and I recently installed RU 8v2. We always had an ActiveSync Access Policy in place where the devices are quarantined until an Administrator goes in and approves or rejects this.
Prior to installing RU 8v2, there used to be a link in the email sent to Administrators to click on to login to the ECP and approve this device. However, since the install of this update, there is no link in the emails now. It just informs you that you need
to login to ECP and view the quarantined devices. Has this been removed in the RU?
Thanks

Hi,
According to your post, I understand that quarantine notifications e-mail will not send to administrators after install Exchange 2010 SP3 RU8v2.
If I misunderstand your concern, please do not hesitate to let me know.
Please login ECP to double check the Allow/Block/Quarantine list rule configuration, for your reference:
http://blogs.technet.com/b/exchange/archive/2010/11/15/3411539.aspx
Besides, Exchange 2010 SP3 RU 9 has released on March 17, 2015. Please upgrade to latest version.
Additional, this issue is related to ActiveSync. Please We recommend contact Mobility and ActiveSync Team so that you can get more professional suggestion.

Exchange 2010 Mailbox automapping issues after updated to Rollup 5 for Exchange Server 2010 SP3

Hi,
i have problem with Outlook Uses who have Full Access on other mailbox.
An authentication window pop up very time a user start Outlook.
If i remove the access everything is ok.
if i insert manual the mailbox everything is ok
The System was for 3 days ago updated to Rollup 5 for Exchange Server 2010 SP3
Before the update, was no issue.
i will appreciated any help
Thanks

Same issue here. Ever since we installed Update Rollup 5 for SP3 Exchange 2010 mailboxes that were auto mapped are not accessible. They all get the same error.
Cannot expand the folder. The set of folders cannot be opened. The attempt to log on to the Microsoft Exchange has failed.
What I have been doing is removing the users permission, then adding them back using the noautomap switch in Powershell. After doing that, the user manually adds the mailbox and all is well.
Just a note here, I suspect it may have something to do with the version of Outlook 2010. We are running an older version here. I think only SP1 with no other incremental updates. Office is up to SP2. Also, one of the users I was working with could not access
the mailbox no matter what we tried but she can walk over to another workstation and open Outlook and access the very same mailbox so that pretty much proves its software related particularly with Outlook.
I cannot reproduce the problem on a workstation (XP) with a newer version of Outlook.
This has been wearing me out and I suspected the Update Rollup all long. Now I am confident as others are having the same problem. If you find out anything on how to fix this other than the steps above, let me know.

Migrate from Exchange Server 2011 to Mac OSX Lion Mail Server

Hi all,
I'm looking to migrate from Exchange Server 2011 to Mac OSX Lion Mail Server. I work for a company with roughly 30 employees and they use exchange for mail, contacts and calendars. We want to take full advantage of OSX Server and to completly get off of exchange.
What are the best ways to do this? Are there any tools available to help this process?

I agree with the points made by Strontium90. If you have any PCs then Apple's mail/contacts/calendar software is a poor choice. Kerio Connect as a mail/contacts/calendar server would not only support Macs but would also do a good job supporting PCs running Outlook.
If you are going to become a pure Apple site, then you could use just the Apple software and this would be cheaper than using Kerio. For 30 users this might be a suitable solution, however even in a pure Apple environment many people prefer Kerio. For example I find Kerio much more pleasent when dealing with email addresses across multiple domains, email aliases, email group addresses, and so on. Kerio also has built-in email archiving, that is keeping a record of all emails. Kerio also provides a web-browser client for accessing email, calendar and contacts. It is worth noting that as standard Mountain Lion Server no longer includes a webmail feature. While I personally find the Kerio webclient rather ugly it does work.
There are some annoyances I have with Kerio, firstly they have always charged a 'maintenance' fee for their software. This provided access to software updates, and in the past also provided access to Kerio technical support. Unfortunately they now only let you make two (2) support cases per year for that cost, and you now have to pay extra for any more cases. Also while they added support for EWS (Exchange Web Service) to allow using Outlook 2011 for Mac as a supported email client, they did a poor job of this so that it does not work properly with any other EWS compatible client. This means it will not work in EWS mode with Apple Mail, nor with Outlook for Windows. While there are other ways to connect these other clients, this seems a foolish move and there have been plenty of requests to fix this.
Apple's Mail client uses EWS to connect to a 'real' MS Exhange server.

Migrate from Exchange Server 2010 sp3 to 2013 sp1
