Exchange 2010 - Decommissioning Exchange 2007 Coexistence and Removal of Public Folders

We are about to decommission exchange 2007, currently in coexistence with Exchange 2010.
We do not want to use ANY public folders in exchange 2010 going forward. Will do this after decom of 2007:
http://technet.microsoft.com/en-us/library/dd876883(v=exchg.141).aspx
I see this in the outlook connection status in outlook:
I have changed all Exchange 2010 mailbox databases to use a temporary 2010 public folders db named "public1" so that it is not communicating with the 2007 mailbox virtual server. However, the exact same connection status appears after I changed
the 2010 mailbox DBs to use a 2010 public folder db instead of the old 2007.
Question is, is it safe to decom the 2007 environment now? Is it normal to still have a connection to 2007 in "connection status" in outlook when the users mailbox is on a 2010 mailbox db? Is this connection related to public folders or something
else that needs modified before decom?
Thanks,
Josh

So, that wasn't the answer. I switched the Public folder DB on each mailbox database to a exchange 2010 server, PF DB, but hadn't actually moved any data from 2007 to 2010.
I didnt realize this is needed when we don't use public folders except for free-busy, default, etc.
What is the correct way to move the default public folders to a 2010 public folder?
I'm using the below URL as a template to migrate this info to a 2010 PF db.
https://www.simple-talk.com/sysadmin/exchange/upgrade-from-exchange-2007-to-exchange-2010---part-ii/
"The user Public Folders then need to be replicated to the Exchange 2010 Public Folder database as well. It is possible to manually configure
all Public Folders with a new replication partner, but it’s better to use PowerShell scripts that Microsoft delivers with Exchange Server 2010. Open the Exchange Management Shell and navigate to the Scripts directory
by entering the CD $ExScripts command,
and execute the following script:
AddReplicaToPFRecursive.ps1 -Server 2007MBX -TopPublicFolder "\"
-ServerToAdd 2010MBX"
My question is, do I have to do this "3rd step" since I don't think i have any custom "user public folders". Is this the user's free busy that I have to migrate, or is this author referring to custom PF db info?
Do I have to have public folders for free-busy and default exchange services at all in 2010?

Exchange 2010 Migration to 2013 Coexistence url's

Hello,
What exactly is required for the virtual directory url setup for Exchange 2010 coexisting with Exchange 2013? I have been searching online a lot preparing for my Exchange 2013 deployment and can't see to find a clear answer. The information
I have come across from TechNet and other sources is all over the place with some stuff saying the external url needs to be empty while others say it should match Exchange 2013's setup. Others say the internal url should be empty while
only the external should be populated. And I have even seen others say nothing on Exchange 2010 has to be touched and that Exchange 2013 will figure proxying out on its own once I configure the new url's on it.
So what is supposed to be setup for the ExternalUrl and InternalURL to in Excahnge 2010 for coexistence with 2013? Currently my
existing Exchange 2010 is internet facing with the plan of moving that to Exchange 2013 once that goes in as per Microsoft directions on implementing coexistence.

Read the article below from Ross Smith. There can't be better article than this:
http://blogs.technet.com/b/exchange/archive/2014/03/12/client-connectivity-in-an-exchange-2013-coexistence-environment.aspx
If exchange 2010 and 2013 are on same site, then you need to:
1. Remove External URL from Exchange 2010 CAS servers, retain the Internal URL
2. Move the SSL certificates from Exchange 2010 to Exchange 2013
3. Point the external URL to Exchange 2013 instead of Exchange 2010
4. Of course, you would need to re-configure Autodiscover, Web Services URLs on Exchange 2013 CAS servers.
Once this is done, for any mailbox that is hosted on Exchange 2010, Exchange 2013 would proxy the connections and deliver the content.

Copy UM settings and prompts from Exchange 2010 to Exchange Online

When I migrated UM from Exchange 2007 to Exchange 2010, there is a script called "MigrateUMCustomPrompts.ps1"
that would copy over all the customized greeting files.
We are now migrating from Exchange 2010 to Exchange Online and will be using Exchange Online UM. Is there a similar script to copy over the files just like
the on-prem?

Sorry, I don't share code examples in most cases because they're generally one-off customer-specific scripts and I'm not in a position to answer lots of follow-up questions about them.

Exchange 2010 to Exchange 2013 Migration and Architect a resilient and high availability exchange setup

Hi,
I currently have a single Exchange 2010 Server that has all the roles supporting about 500 users. I plan to upgrade to 2013 and move to a four server HA Exchange setup (a CAS array with 2 Server as CAS servers and one DAG with 2 mailbox Servers). My
goal is to plan out the transition in steps with no downtime. Email is most critical with my company.
Exchange 2010 is running SP3 on a Windows Server 2010 and a Separate Server as archive. In the new setup, rather than having a separate server for archiving, I am just going to put that on a separate partition.
Here is what I have planned so far.
1. Build out four Servers. 2 CAS and 2 Mailbox Servers. Mailbox Servers have 4 partitions each. One for OS. Second for DB. Third for Logs and Fourth for Archives.
2. Prepare AD for exchange 2013.
3. Install Exchange roles. CAS on two servers and mailbox on 2 servers. Add a DAG. Someone had suggested to me to use an odd number so 3 or 5. Is that a requirement?
4. I am using a third party load balancer for CAS array instead of NLB so I will be setting up that.
5. Do post install to ready up the new CAS. While doing this, can i use the same parameters as assigned on exchange 2010 like can i use the webmail URL for outlook anywhere, OAB etc.
6. Once this is done. I plan to move a few mailboxes as test to the new mailbox servers or DAG.
7. Testing outlook setups on new servers. inbound and outbound email tests.
once this is done, I can migrate over and point all my MX records to the new servers.
Please let me know your thoughts and what am I missing. I like to solidify a flowchart of all steps that I need to do before I start the migration.
thank you for your help in advance

Hi,
okay, you can use 4 virtual servers. But there is no need to deploy dedicated server roles (CAS + MBX). It is better to deploy multi-role Exchange servers, also virtual! You could install 2 multi-role servers and if the company growths, install another multi-role,
and so on. It's much more simpler, better and less expensive.
CAS-Array is only an Active Directory object, nothing more. The load balancer controls the sessions on which CAS the user will terminate. You can read more at
http://blogs.technet.com/b/exchange/archive/2014/03/05/load-balancing-in-exchange-2013.aspx Also there is no session affinity required.
First, build the complete Exchange 2013 architecture. High availability for your data is a DAG and for your CAS you use a load balancer.

Exchange 2010 to Exchange 2013 Public Folder Problem

Dear Experts,
I am in a face of migrating Exchange 2010 to Exchange 2013. Below are my infrastructure details,
1) Parent Domain in Site A (abc.com)
2) One Child domain in Site A named child1.abc.com and Exchange 2007 is running in Site A child domain
3) One Child domain in Site B named me.abc.com and currently Exchange 2010 is running in Site B.
I have installed Exchange 2013 in Site B in coexistence scenario now Exchange 2013 users in Site B trying to attempt connection with a public folder store in the Site A Exchange 2007 servers instead of Site B Exchange 2010 servers.
Anyone help will be highly appreciated.
Thanks & Regards,
ZB

so you want users to access the PF in site B.
Check the setting of Databases in Exchange 2013 and find out what is default Public Folder setup for those Database. You will basically need to change the default Public Folder in Exchange 2013 from Site A PF to Site B,, the way you have explained the scenario.
run this for Exchanger 2013 DA

OST corrupt when moving Mailbox from Exchange 2010 to Exchange 2010

Anyone come across this?
Moving a mailbox on Exchange 2010 to Exchange 2013 - the outlook client wont connect, if you remove the OST and allow outlook to recreate it comes good again.
outlook client knows the mailbox has moved as it connects to the new server
Not happening to every mailbox
thak=nks

Hi,
After you move mailbox from Exchange 2010 to Exchange 2013, Outlook should still work.
Is there any error message when these affected users try to connect? If there is, please post here for further analysis.
I saw someone failed to connect to the new Exchange server after they moved mailbox, then they restarted the Microsoft Exchange Information Store service and restarted Outlook, it worked.
If you haven't tried this, you can restart the Microsoft Exchange Information Store service to check the result.

Exchange 2010 to Exchange 2013 mail flow?

We are planning to migrate Exchange 2010 to Exchange 2013.
I understand that we need to upgrade the CAS to 2013 for Internet Facing.
What about mail flow. Currently, Internet mail flows to Exchange 2010 (single site). Can I keep it for sometime after introducing 2013 and do the cutover of HUB once all the mailboxes are moved to 2013? Or I have to get the mail flow to 2013 first.
Also, how does HUB 2010 transfer mail or receive mail from 2013? Does it get from the CAS proxy in 2013 or from HUB?
Thanks!!!

Yes, you can. But my preference is to move the mail routing early in the migration, usually even before moving mailboxes, because I believe it reduces the risk of a service interruption.
I believe it goes through the front-end transport on the CAS, since that is the TCP port 25 service.

Moving from Exchange 2010 to Exchange Online: AD issue

Dear All,
Our company will moving from Exchange 2010 to Exchange Online and we have a on-premise WinSer 2008R2 for AD.
Currently, user have to login to our domain and use the same ID and PW to access their outlook.
1.If we move to Exchange online, do we have to do anything with our on-premise AD server?
2.If user prefer using only one ID and PW for PC to access domain and Exchange online, what should we do?
3.Is there any point or do we still need current on-premise AD server after we moved to Exchange Online?
Thank you so much for your attention and help!
Best regards,
Shiloh

Hi,
There are a lot of corrupted items. You can try raising the baditemlimit to 999 to workaround this issue

PF Migration, Multiple Databases (Exchange 2010 to Exchange 2013)

Hey All
We have 3x Public Folder Databases in our exchange environment, I have successfully migrated one of the public folder databases over and see all of your content.
My question is this:
Do I need to run the migration process for each database? or if I run it for one database will that migrate all Public Folder data over to 2013?
Thanks,
Robert
Robert

Hi Robert,
The key point here is to collect and migrate all public folders from PF databases. In most cases several PF databases just have replicas of the same Public Folders, so no need for processing each database specifically.
Enumerate all Public Folders you have in previous Exchange version, compare the list to the Public Folders you have migrated to Exchange 2013 using the most up to date source. If both lists match each other - you have migrated all necessary public folders
and you don't need to process other PF databases.

Removing Exchange 2007 from SBS 2008 (In an Exchange 2010 Coexistance Scenario) - In order to remove 2007 Mailbox Objects from Active Directory and remove the SBS2008 server completely

I'm trying to remove Exchange 2007 from an SBS 2008 server
(Server 2008 Standard FE). My ultimate goal is to completely remove the SBS 2008 Server from the network environment.
We have an Exchange 2010 Coexistence Scenario and Mailboxes/Public Folders/etc have been moved over to the 2010 mail server, on Server 2008 R2.
I have moved all Shares, FSMO roles, DHCP, DNS, etc over to their respective servers. We have two full blown DC's in the environment.
I'm ready to remove Exchange 2007 from SBS 2008 and DCPROMO the server. I can NOT seem to find a TechNet article that shows me how
to proceed in this kind of scenario. I am trying to use the TechNet article:
http://technet.microsoft.com/en-us/library/dd728003(v=ws.10).aspx
This article references Disabling Mailboxes, Removing OAB, Removing Public Folder Databases, then uninstalling Exchange using the Setup Wizard.
When I go to Disable Mailboxes I get the following error:
Microsoft Exchange Error
Action 'Disable' could not be performed on object 'Username (edited)'.
Username (edited)
Failed
Error:
Object cannot be saved because its ExchangeVersion property is 0.10 (14.0.100.0), which is not supported by the current version 0.1 (8.0.535.0). You will need a later version of Exchange.
OK
I really don't see why I need to Disable Mailboxes, Remove OAB and Public Folder Databases since they have been moved to 2010. I just want
to remove Exchange 2007 and DCPROMO this server (actually I just want to remove any lingering Exchange AD Objects referring to the SBS 2008 Server, using the easiest and cleanest method possible).
Can someone point me in the right direction?
Thanks!

Hi,
Based on your description, it seems that you are in a migration process (migrate SBS 2008 to Windows Server
2008 R2). Now, you want to remove Exchange Server and demote server. If anything I misunderstand, please don’t hesitate to let me know.
On current situation, please refer to following articles and check if can help you.

Exchange 2013 and 2007 coexistence and redirects

Hi all,
I'm settings up the coexistence but i've got a problem.
I've got 3 sites:
Site A: Exchange 2013 cas and mailbox
Site B: Exchange 2007 hub/cas and mailbox
Site C: Exchange 2007 hub/cas and mailbox
The problem is the owa and active sync redirect. I can open a mailbox located in site B where the legacy.domain.com dns record points, but i cannot open a mailbox from the exchange 2013 nor 2007 owa from site B to C.
I configured only the internal url leaving the external one blank.
How do i redirect all the requests to a mailbox located in site C from site A and B?
Thanks,
D.

You need to have External URL too, so that redirection can take place.

Thank you for the reply, I have checked the applicationHost.config as indicated, and the path shown is the same as in the error message, there is no D:\Exchange,Server\V14\Bin\ path, it is as indicated in the error D:\Exchange2010\Bin\. Here is the section
from that applicationHost.config file:

            <add name="kerbauth" image="D:\Exchange2010\Bin\kerbauth.dll" />
As indicated in my post, I have replaced the kerbauth.dll from another functioning exchange 2010 installation and it has not corrected the issue.
At this point I am looking for a solution for removing the mailbox role and being able to complete the uninstall of exchange and perform a clean install.
Any additional help with this is very much appreciated.
