CAS server redirection with Hybrid Exchange across multiple regions

June 11, 2015, 9:22 am

Hello,

We are deploying a fresh Exchange 2013 organisation as a Hybrid model.  We will deploy as a single Office 365 tenant in Europe, and a single Exchange organisation. Some countries that cannot consume the Office 365 /Exchange online from Europe (perhaps for legal / compliance / performance reasons) will have a local Exchange deployment in country.

We have deployed a pair of Exchange hybrid servers to our central European location, and have setup dns to point to these servers for autodiscovery.company.com and webmail.company.com

For those users which have a mailbox in country, we want them to be redirected to the local CAS server, we do NOT want them to use the European Hybrid Exchange server as a CAS and proxy to the in country mailbox server (which is far away, high latency).

How can we control this and ensure our users get a CAS redirection to the correct local Exchange CAS?

Thanks

Hi,

I installed Exchange 2013 in exchange 2010 co-existence, I am able to move mailboxes from Exchange 2010 to 2013. After moved I have strange issue that, all user's Outlook is keep pop-up with security certificate error and disconnects.

here is my scenario.

1. we have two DNS company.com & corp.company.com. both my exchange servers are in corp.company.com however smtp domain isusername@company.com

2. before I change internal DNS, autodiscover entry was in corp.company.com and webmail was in both DNS. Now I pointed to new server with entries in same domain.

configured Outlook anywhere in exchange 2013 exchange.corp.company.com & same in exchange 2010. but now my users are unable to connect to Outlook with security certificate error. I have CA signed certificate for webmail.company.com.

with above said scenario, how can I solve this problem or can you please guide to verify the autodiscover, SCP, Outlook anywhere in both exchange versions? (I have one server in each 2010 & 2013) quick help would be really appreciated.

Thanks, Karthikeyan R

Exch 2007 -> 2013 Outlook Anywhere Authentication settings

June 12, 2015, 6:34 am

I'm wondering if anyone can help me out or offer advice.  I'm in the midst of an Exchange 2007->2013 migration and am at the point where I need to change my 2007 Exchange URLs to "legacy" and then flip "autodiscover" and "mail" DNS to point to Exchange 2013. 

My existing Exchange 2007 environment did NOT have Outlook Anywhere enabled, so I have done that and tested internally and it works fine.  Externally it doesn't work, but I think that may be because my ExternalClientAuthenticationMethod is set to NTLM (?).  Unless this affects the migration I'm not concerned about having it working externally - we never had it before so don't need it now.

What I'm not sure about is the authentication methods needed for each server.  I will have 2 Exchange 2013 MBX/CAS servers behind an F5 load balancer.  The 3rd server shown is my 2007 HUB/CAS.


Server                             : EXCH13_1
InternalClientAuthenticationMethod : Ntlm
ExternalClientAuthenticationMethod : Ntlm
ExternalClientsRequireSsl          : True
InternalClientsRequireSsl          : True
IISAuthenticationMethods           : {Basic, Ntlm, Negotiate}

Server                             : EXCH13_2
InternalClientAuthenticationMethod : Ntlm
ExternalClientAuthenticationMethod : Ntlm
ExternalClientsRequireSsl          : True
InternalClientsRequireSsl          : True
IISAuthenticationMethods           : {Basic, Ntlm, Negotiate}

Server                             : Exch07
InternalClientAuthenticationMethod : Ntlm
ExternalClientAuthenticationMethod : Ntlm
ExternalClientsRequireSsl          : True
InternalClientsRequireSsl          : False
IISAuthenticationMethods           : {Ntlm}


Given the information shown above, is everything set correctly for me to go ahead and set "legacy" and flip DNS?  Obviously I want this to go as seamless as possible :)


Thanks

Outlook Anywhere redirect not working (Exchange 2013 to Exchange 2007)

May 13, 2013, 9:07 am

Hi guys,

At this moment, I have Exchange 2013 and Exchange 2007 coexisting.

I am publishing Exchange 2013 through UAG and Exchange 2007 with ISA. In 2013 everything is fine. In Exchange 2007, I have set up a legacy namespace, the name is also included in the certs, external DNS and all External URL's on this side.

Apart from having to log into various OWA interfaces for Exchange 2007 users that is pretty much fine too apart from Outlook Anywhere. While it works well for a 2013 user, a 2007 user has to login many times and then it fails.

I did some testing with ExRCA with a 2007 user, and get the error: "A Web exception occurred because an HTTP 302 - Redirect response"

Can anyone shed light on my problem?

Thanks!

Exchange 2013 users unable to access Exchange 2007 Public Folders

May 15, 2013, 11:38 pm

Hi all.

I've been working on setting up Exchange 2013 in our Exchange 2007 environment.  I've managed to install it, configure it, move a handful of mailboxes, and fix several issues (2013 users being asked to login, free/busy maximum settings mismatch, Autodiscover not really updating the settings in Outlook clients...).  However, I'm stuck on getting Exchange 2013 users to access Exchange 2007 public folders.  Because the new server is very much in a development stage, I can't migrate the public folders over and won't until the mailboxes are thoroughly tested and fully migrated.

According to the public folders FAQ at http://technet.microsoft.com/en-us/library/jj150538(v=exchg.150).aspx, it's both possible and impossible to get new users to access legacy folders.

From "Considerations:"

Exchange 2013 no longer supports public folder databases. Therefore, there’s no coexistence with legacy public folders. As a result, Exchange 2013 is unable to read from the hierarchy stored in a public folder database on Exchange 2010 or Exchange 2007 servers.

From "Migrate public folders from previous versions:"

...However, user mailboxes on Exchange 2013 servers or Exchange Online can connect to legacy public folders. Exchange 2013 public folders and legacy public folders can’t exist in your Exchange organization simultaneously....

I did originally start to build the master hierarchy in 2013 before finding this page, but I have since deleted the hierarchy from Exchange and from AD via ADSIEdit.

When a 2013 user tries to access a 2007 public folder, they are met with "Cannot expand the folder. Microsoft Exchange is not available. Either there are network problems of the Exchange server is down for maintenance. (<correct info about the the legacy 2007 server's DN>)"

I've reviewed the RPC logs from the new server and am seeing what looks like a proper redirect command to the Outlook client.  But the Outlook client can't connect to the public folders.

I've tested public folders in OWA and they don't work there.  I've verified that the services are started on both the new and old servers.  And I've used the Outlook Connection Status tool to observe how Outlook seems stuck in a perpetual "connecting" state to the old mail server, even when I'm not trying to access a public folder.

So my question then, is using Exchange 2013 to access Exchange 2007 public folders actually possible or not?  If so, what else can I check to find out why I can't open legacy public folders?  We need to access some of the shared folders for collaboration, and I'm trying to avoid moving the upgraded users back into Exchange 2007.  This seems to be about the last major problem I have before I can start migrating all of the other users.

Thanks!

Alan

PS - Microsoft, please update your Exchange 2013 Public Folders FAQ to clarify if this is possible or not.  You state both in two adjacent sections.

“You can't view more than 5 calendars at once. To view this calendar, cancel your selection of another calendar”

We are migrating to Exchange 2013 and moved some mailboxes to Exchange 2013.

Now all of the sudden the test users that are on Exchange 2013 OWA are facing warning:

“You can't view more than 5 calendars at once. To view this calendar, cancel your selection of another calendar”

This warning occurs when they select more than 5 calendars in OWA where they have permissions on.

1)Is this adjustable and how ?

I know this is NOT adjustable with the OWAConcurrency setting in the throttlingpolicy

OWAMaxConcurrency :TheOWAMaxConcurrency parameter specifies how many concurrent connections an Outlook Web App user can have against an Exchange server at one time

These errors occur 2-3 times a minute. the environment is in migration from Exch 2007 to Exch 2013. I can send and receive emails from/to the Exch 2013 server using the new account created following the deployment assistant.

Also, the services failing include EWS (shown below) as well as Autodiscovery.

How to take Exchange Management Shell Set-transportconfigure -maxsendsize command effectively?

Dear Sir,

       Customer would like to change the Exchange 2013 send attachment size limit from 10MB default to 20MB in standard version with SP1.  I understand that it can be done in the Exchange management shell using the command:

- Set-TransportConfigure -MaxSendSize 20000000

      However, it seems that this command can only take effectively until reboot or restart Exchange Information Store service. I find that it will not capable to take command effectively if restart exchange transport service.  If stop and restart the IS service, it will cause interruption of user access email.  Do it has any other command or solution to take the action immediately without interrupt user by restarting IS service?

      If I doesn't take any action of restart service, anyone know what is the default time need to wait unit the command action take effective?

Regards,

Joe Tam

Who would ever had thought this would even be an issue. but it is.

I am having trouble installing exchange 2013 in a SINGLE server 2012 PDC enviroment.

 Got through prerequisite checks and setup fails at mailbox role:cleint access service 

Could not grant Network Service access to the certificate with thumbprint ABC7....... because a cryptographic exception was thrown.".

gave the cert the permissions it wanted and still failed.

This small of an environment does not justify multiple servers.

Is there any way to pull off an exchange 2013 install in a single PDC environment.

if not, what is the next easiest step.

Thanks, John

Dear All,

I have an Exchange Server running in my organization and is successfully serving to internal users. By using one of the POP3 tool i am successfully receiving external user emails to Exchange Server as well. But i have few confusions and problems

1. I have oracle based payslip system that is unable to send payslip to those who have their emails on yahoo and hotmail but it successfully sends to all who are confiigured with exchange server. How to resolve this???

2. Second issue is why we need to use POP3 external tools to setup with Exchange in order to handly pop3 mails.?? why exchange do not have such functionality???

3. Lastly, I have implemented One Exchange Server along with its DAG as high availability. for external users we have configured our ms record entries to the domain hosting company and whenever they have issue in their firewall they block exchange public ip addresses and our external email are then blocked. What is the recommended Exchange Scenario in this regards???

Thanks

We have 150 users moved to Exchange 2013 as are pilot.   These users including my account have difficulty scheduling meetings.  When reviewing free/busy data, users who are still on Exchange 2010 display and hash marks for availability.  Pressing Alt-k  will refresh and eventually display free/busy, but takes several minutes, and some users may never display free/busy info.

Any ideas on how to resolve?  Other than quickly moving the remaining 3500 users to 2013.

I have some issues with one of my Exchange2013-servers and want to upgrade from CU4 to CU8 to see if this will correct the issues. 2 questions:

  • Where can I find step-by-step documentation on how to perform the upgrade, including the necessary steps to prepare AD?
  • I have found articles saying that any customizations on the servers will be lost, what kind of customizations could this be? I hope that all setup with connectors, URLs and so on is preserved during the upgrade?

The server with the issues is member of a DAG.

Exchange 2013 CUs do not remove earlier version files and folders

June 16, 2015, 3:42 am

I have an Exchange 2013 installation started with SP1 that I have kept updated installing the Cumulative Updates when they were released.

I have observed that after each CU installation the C: free space (Exchange is installed on C:) was less then before. So I searched in the Exchange install directory and I have found a lot of sub-directories named with an Exchange build number, expecially under the ClientAccess install dir and the OWA subdir.

For instance, under C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\Owa I have many folders named "15.0.995.28", "15.0.995.32", "15.0.1044.21", "15.0.1044.27", "15.0.1076.2", "15.0.1076.10".

The C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\Owa\prem directory has the same subfolders and is consuming a lot of disk space.

As I could understand, the CU setup should remove the older files but it seems that it does not and keeps older version in these directories. I have tried installing a fresh Exchange 2013 CU8 on a new server and these directories are not present.

The question is: is that correct?

And: can I safely delete the older versions folders?

Thanks
