Hi,

we have coexistence of Exchange server 2010 and 2013 ,one of the users mailbox resides on exchange server 2013 ,i am trying to configure the mailbox on outlook 2007 ,when i give my outlook anywhere address of exchange 2013 on Microsoft exchange field  and the user name and do check name it does not resolves,at the same time when i am give exchange 2010 CAS server address on the server field it resolves the name.

More info.

there are two cas servers, one for exchange 2010 and one for exchange 2013. The one for exchange 2010  detects the system mailbox on exchange 2013 but the cas of exchnage 2013 does not detect system mailbox on exchange 2013 itself

Thanks

Abu

You need to create a mail contact for the users of Exchange 2010 in 2013 and vice-verse. And point their "Target Mailbox" attribute to their respective servers.

Hi Abu,

Is this issue for one user or all users.

Do you have autodiscover configured correctly. all ExternalURL,InternalURL and AutodiscoverURI set.

What do you mean by CAS doesn't detect system mailbox, how are you testing it?

Try to configure the mailbox manually. Read my post here to figure out how.

Dear Satya,

Thanks for your reply.

Q,Is this issue for one user or all users.

we are still in migration process from exchange 2010 to 2013 and moved just 20 users as of now ,i tested other users it siply does not resolves when i do check name by putting exchnage 2013 CAS server name

Q ,Do you have autodiscover configured correctly. all ExternalURL,InternalURL and AutodiscoverURI set.

A, im pretty sure auto discover is configured correctly,if i want to verify if its correct what is the process to verify?

Q,What do you mean by CAS doesn't detect system mailbox, how are you testing it?

A, i came to know about this problem when i was configuring outlook for one user whose mailbox resides on exchange 2013 ,when i put the exchange CAS 2013 server address on exchange server field and  user name and make a check name it does not resolves at the same time when i put exchange 2010 address and do a check name it resolves.

Q,Try to configure the mailbox manually

A,i tried configuring manually but no luck.

i would like to share some more details i.e

the webmail address for exchange 2010 and 2013 is different in our case is that normal.

for e.g.. our exchange 2010 webmail address was webmail.abc.com and 2013 is outlook.abc.com

Hi Abu,

Thanks for the inputs, before I comment on checking the autodiscover config. I would like you to check the below post link(Sorry my earlier link was pointing somewhere else)

Ex2013 works differently and hence you can no longer use a CAS Servername or alias to configure a account like earlier versions. You need to input the unique ExchangeGUID for the mailbox.

Refer to this link for Manually configure Outlook for Ex2013

Once we confirm that Exchange is setup correctly we can focus on autodiscover part. Which is the only means users can configure automatically for Ex2013 accounts on OUtlook.

To test it simply open this URL using IE. See if you get some XML data with Invalid error. IF yes Autodiscover is fine (initial test atleast)

https://autodiscover.domain.com/Autodiscover/Autodiscover.xml

Basically the autodiscover should be pointing to Ex2013 IP and not Ex2010. Ex2013 in co-existance scenario is aware and would automatically proxy the requests to Ex2010

In the EAC, go to Servers > Virtual directories. Verify all the directories are updated with the primary URL meant for Ex2013 in Internal URL ,External URL .

You can run this to confirm and check if you have correctly configured all pre-requisites and post-migration task correctly.

Microsoft Exchange Server Deployment Assistant

When you run this command in Ex2010 the external hostname should be Ex2013 server URL.

Get-ExchangeServer | Where {($_.AdminDisplayVersion -Like "Version 14*") -And ($_.ServerRole -Like "*ClientAccess*")} | Get-OutlookAnywhere | Format-Table Server, ClientAuthenticationMethod, IISAuthenticationMethods, SSLOffloading, ExternalHostname -Auto

This command should also listing SCP Ex2013 for both Ex2010 and Ex2013 cas.

 Get-ClientAccessServer | Format-Table Name, AutoDiscoverServiceInternalUri -Auto

Dear Satya,

perfect response from you, i appreciate your support on this,your points above will bring us closer to understand my problem

i am using outlook 2007 to connect to the mailbox which exists on exchange 2013.

i am using this mailbox for Symantec enterprise vault archiving,the server is logged in with Symantec enterprise vault service account so when i configure outlook i have to configure it manually ,since the system mailbox in not logged in i am logged in through service account.

and as you said 

"Ex2013 works differently and hence you can no longer use a CAS Servername or alias to configure a account like earlier versions. You need to input the unique ExchangeGUID for the mailbox

so in this case how should i make my outlook configuration work for an account which is not logged with the same account.

Hi Abu,

It doesn't matter which account you are logged in, you need to have full mailbox rights to configure the profile or the user account. Make sure the ExchangeGUID you put in is the correct account's.

Not quite sure about the archiving part. First try to configure the primary mailbox in Outlook.

Thanks Satya,

already the service account has full mailbox right on the system mailbox which i am trying to configure,how do i get the guid for that mailbox?

Hi Bakar,

We could use the following command to get GUID:

Get-mailbox <MailboxName> | fl Name,ExchangeGUID

If there are any questions regarding this issue, please be free to let me know.

Best Regard,

Jim

Satya,thanks a ton ,my issue got resolved with your help

Hi Abu,

Glad it worked out for you.

thanks Jim,

i saw your post late, i used an test PC and configured that mailbox on outlook 2013 and i was able to get the GUID in that way,will use the PS command next time.
