Outlook Connectivity / Exchange 2010 Coexistence Scenarios

Hello,
I recently migrated to Exchange 2013, autodiscover.domain.com and mail.domain.com are pointing to CAS 2013 for external and internal access. For EX013 users, Outlook establishes connection with both CAS 2010 and CAS 2013 which is fine. For EX2010 users,
Outlook establishes the connection only with CAS 2010 for both internal and external access. My understanding is that CAS 2013 should proxy the connection to CAS 2010, but it doesn't and also after the migration I have to remove and add the profile again for
the changes to take effect for the migrated users. I haven't changed the namespaces, its the same. Any suggestions would be much appreciated.

Hi,
Your understadning is correct. Since only Exchange 2013 is Internet-facing, CAS2013 would proxy all requests for Exchange 2010 external user accessing.
Please make sure the External URL in Exchange 2010 services are all set to $Null and Outlook Anywhere is enabled with the external host name pointed to mail.domain.com. Then the external Exchange 2010 user would connect the Autodiscover service
with autodiscover.domain.com successfully. The other services such as EWS, OOF and OAB request would be send to Exchange 2013 then proxy to Exchange 2010.
For more infromation about the connectivity in Exchange 2013 coexistence environment, please refer to:

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.

Macbook Pro 10.7 Outlook 2011 Exchange 2010 sync

Macbook Pro 10.7 Outlook 2011 Exchange 2010 sync
Asked by: tppltd
I have a customer that uses our hosted solution Server 2008 Exchange 2010 for email access and web dav file share. They have 8 Macbooks connected to the system and they all use Outlook 2011. One user has an issue where he's reading and deleting emails within Outlook on his mac but it isnt updating Exchange which in turn means his iphone isnt clearing down the read and deleted emails. If i log on to the owa mailbox i can see that the emails havent been read or deleted. We have this issue for one user with the newest MacBook. It first occurred 4 months ago and i ended up removing the account and resyncing the whole lot which took a few hours due to the size of the mailbox. I've right clicked the folders and told it to resync but it remains the same. Does anyone have any help they can provide please? thanks
The user doesnt want to rebuild the outlook account. Am i missing somthing obvious

I suggest you post your question on Microsoft's own forums for their Mac software as it's their stuff you have questions about:

Outlook Anywhere settings in a Exchange 2013 coexistence scenario with Exchange 2007

I have exchange 2013 and 2007 set up in a coexist environment. At the moment, the few mailboxes I am testing on Exchange 2013 are getting multiple pop ups in outlook and cannot connect to items like Public Folders on 2007. I found an article
that told me to change the authentication method from Negotiate to NTLM and that broke some of my Lync 2013 compatibility issues on users on exchange 2007 (ie conversation history and they got outlook integration errors.) I would like someone to confirm
if the change I am about to make from doing research will help me in my situation.
Current Setup:
Exchange 2007 OA CAS Settings
ExternalClientAuthenticationMethod : Basic
InternalClientAuthenticationMethod: NTLM
IISAuthenticationMethods : {Basic, Ntlm}
Exchange 2013 OA CAS Settings
ExternalClientAuthenticationMethod : Negotiate
InternalClientAuthenticationMethod: Negotiate
IISAuthenticationMethods : {Basic, Ntlm, Negotiate}
New Settings I am considering based on research:
Exchange 2007 OA CAS Settings
ExternalClientAuthenticationMethod : Basic
InternalClientAuthenticationMethod: Basic
IISAuthenticationMethods : {NTLM}
Exchange 2013 OA CAS Settings
ExternalClientAuthenticationMethod : Basic
InternalClientAuthenticationMethod: Basic
IISAuthenticationMethods : {Basic}
Will this work and eliminate my popups?

Hi,
The following TechNet article indicates that:
“In order to support access for Outlook Anywhere clients whose mailboxes are on legacy versions of Exchange, you will need to make some changes to your environment which are documented in the steps within the
Exchange Deployment Assistant. Specifically,
you will need to enable Outlook Anywhere on your legacy Client Access servers and enable NTLM in addition to basic authentication for the IIS Authentication Method.”

Outlook 2013/Exchange 2010 Free/Busy access issues.

Good Day Everyone,
I am running a Win 2008 R2 environment with Win7 users, using Exchange 2010 and Outlook 2013. Last week my users started experiencing issues with being able to view Free/Busy in the Calendar for any other user. I have checked past issues with this with patches
KB 2837618 and KB 2837643. Neither patch is showing as installed and I have tried a nummber of the suggested fixes offered for that issue to no avail. OWA seems to be working just fine.
Our Outlook version is: 15.0.4605.1003
I need a fix for Outlook users and since I havve 140 users, individual fixes are a not realistic option.
Any assistance would be greatly appreciated.

Hi,
Please test if Out of Office feature works well in Outlook. If Out of Office doesn't work either, it should be Autodiscover related.
Once Autodiscover has not been configured properly, the Free/Busy information may not display correctly. If you are also seeing issues with Out of Office assistant, we may assume that you haven’t correctly setup Autodiscover, since these two symtoms are
common when Autodiscover is not configured correctly.
To verify that, please test Outlook Autodiscover Connectivity:
http://technet.microsoft.com/en-us/library/bb123573.aspx
We can also learn Configure Exchange Services for the Autodiscover Service from:

The Microsoft Exchange Administrator has made a change that requires you quit and restart Outlook in Exchange 2010.

Hi,
We have 2 Exchange 2010 servers with multiple roles installed ,also we have setup cas array on the same with help of Kemp load balancer. Both have 1 public folder on each node.
There are few accounts(including mine) those are recently migrated from Exchange 2003 to Exchange 2010 and they are getting intermittantly an error pop "The Microsoft Exchange administrator has made a change that requires you quit and restart
Outlook"
this generally happens when i switch the network for my laptop but not every time 2-3 times in a week.
i already gone through this link but didn't get any solution. Any help is appreciated.

Amit Rawat | MCITP - Exchange 2007/2010| CCNA |MCSE- 2003| Lync 2010|http://blog.amitrawat.net

Hi,
I recommend you check if any Public Folder on one member of a CAS array.
If yes, it will cause the issue.
I had encountered a similar issue.
The Problem exists when an Outlook client connects into a CAS array initial if
it connects to the CAS array member that contains the PF role, then Outlook
Converges all connections and displays both the Public and Private logons as one
single conneciton to Mail.company.com (the CAS array name) When the Clients IP
address changes, and it Re-connects, if it gets connected to a CAS array member
that does not have the PF server, then we get an ECwrong server Response from
Exchange, Outlook in it's reconnect logic Cannot follow the Redirection Result
that contains the correct PF server name, and displays the Error "the Admin has
made a change that requires you restart Outlook"
Finally, move PF to separate server as a workaround.
Hope this helps!
Thanks.

Thanks !
As i started this question saying i have already read these things . If this is the case i am wonder why microsoft didn't release a technet article where it must discussed about CAS array and Public folder confliction.
However, you said
"if it gets connected to a CAS array member
that does not have the PF server, then we get an ECwrong server Response from Exchange, "
I do have PF on both node then why this pop up.. i do understand if only one node has PF and new connection intiated by outlook connecting to other node which doesn't have PF then it will redirect to the node having PF and while doing so there is
the message.
FYI..
I hve two node server having CAS array and DAG configured on it. keep one thing in mind i am using kemp load balancer for CAS array.
I will appreciate all your help if you elaborate in depth.

Outlook 2013 / Exchange 2010 constantly prompting for password

I as well as many users keep getting prompted for User/pass in outlook. This usually happens when I go from LAN to WIFI or from office to home. For example, If I close my laptop (not shut down) and head home then log back in and connect to my
VPN I usually get prompted for my user/pass for outlook. I type the correct user/pass but it does not accept and immeadiatly prompts for me to re enter. If I close down Outlook and re open the issue is fixed however this is not fixing this issue
and the owner of the company is receiving this error as well. I would like to find a solution so that either it does not prompt and automatically updates once it is reconnected with the network via VPN.
Any suggestions?
Thank you

Outlook is simply not good at that with the existing protocols in Exchange 2010. Exchange 2013 uses MAPI over HTTP which may make that experience better.
Switching networks with Outlook open is typically not a good user experience.

Exchange 2003 and Exchange 2010 Coexistence Activesync Issue

Hello,
I am currently on the progress of migrating mails from Exchange 2003 SP2 to Exchange 2010 SP3. Before I can do actual migration, I need to make sure that OWA and Activesync works when Exchange 2010 becomes Internet facing.
Right now Exchange 2003 is Internet facing while Exchange 2010 is internal LAN only. OWA login from Exchange 2010 to a mailbox in Exchange 2003 works fine. However, trying to open a mailbox in Exchange 2003 from Exchange 2010 Activesync fails.
Activesync login from Exchange 2010 to a mailbox in Exchange 2010 works fine, as well as logging in from Exchange 2003 to mailbox in Exchange 2003.
Tests using AccessMyLAN ActiveSync Tester using Exchange 2010 as entry point are inconclusive. The test shows the app successfully contacting ActiveSync version 6.5 which is Exchange 2003, but results in "Activesync detected, but not correctly configured."
Tests using Test-ActiveSyncConnectivity from Exchange 2010 reveals Error HTTP 400 when contacting Exchange 2003. The cmdlet also shows it successfully contacting Activesync version 6.5 (Exchange 2003).
I have searched around, installed hotfix KB937031, enabled Integrated Windows Authentication on Exchange 2003 Microsoft-Server-Activesync, disabled Require SSL for Microsoft-Server-Activesync and exchange-oma, yet I still can't connect to a mailbox inside
Exchange 2003 through ActiveSync 2010. Website Multiple Identities for port 80 has been set correctly. Exchange 2003 has Forms-Based Authentication Enabled and is the one thing we haven't tried disabling yet.
We want to make sure everything works first, then make Exchange 2010 Internet facing, and finally do the mail migration. We do not want to migrate everyone in a single sitting. Please if anyone have ideas any help is welcomed!

Exchange 2010 will proxy ActiveSync for Exchange 2003. For OWA, it will redirect, so you need a legacy redirect URL. You can test all of this internally without changing your Internet connection. For ActiveSync you can use a WiFi connection.

Can't manage distribution group from Outlook with Exchange 2010 or Exchange 2013 mailbox

Hi All,
In my environment we are using exchange 2010 that contains the distribution groups which has been migrated from exchange 2003 environment .On that one of the distribution group is having an problem for the user who had an access to manage DL'S via outlook
but he can't able to manage it.When we add the new user to manage same DL and the new user tries to manage the DL via outlook it happens without any issues.
issue occurs only for the user who has already have the manage access permission on the DL where the group was on exchange 2003 before migrated to exchange 2010.
Reffered blog : http://support2.microsoft.com/kb/2586832?wa=wsignin1.0
We have done all the settings defined on the above mentioned link but still we are facing the issue.
In addition to that , we have forcefully upgraded the DL too by using the below mentioned command.
set-distributiongroup -identity "name of the problematic DL" -forceupgrade
Please all of you provide your valuable suggestions to overcome this issue .

Thanks S.Nithyanandham

Hi S.Nithyanandham,
From your description, I would like to verify if the problematic manager user is a member of security group. If yes, this issue will occur. In Exchange 2010, distribution groups can't be managed by groups, only individual users can manage groups. But in
Exchange 2003, it is possible to use groups to manage a distribution group.
For more information, here is a blog for your reference.

Problems with archive mailbox in Outlook, with exchange 2010+2013 co-existence

Hi!
We have an Exchange 2010 environment plus one Exchange 2013 MBX server meant for archive mailbox purpose. (We are going to upgrade to 2013 but with over 20.000 mailboxes it will take som time. Therefore we need to co-exist with primary mbx on 2010 and archive
mbx on 2013 for some time.)
My primary mailbox is on a 2010 MBX server, and I have today given myself an archive mbx on 2013 MBX server.
When I use OWA, both my primary mailbox and my archive shows up and everything works 100% fine!
But when I try Outlook 2010 or Outlook 2013, only my primary mailbox works. The archive mailbox shows up, but generates an error when accessing it:
"The set of folders cannot be opened. Microsoft Exchange is not available. Either there are network problems or the Exchange server is down for maintenance"
Anyone who knows about this issue? Would we nice to know why it works in OWA but not in Outlook.
Thanks!
Trond Jenssen

Hi，
Please try to recreate a profile to access archieve mailbox.

Outlook 2013/ Exchange 2010 User Mailbox reached Limit and OWA is not reachable

Hello Folks,I have a strange Outlook/ Exchange problem with one of our Users, interestingly it’s the Boss of our company….The Background:- We have 2 Domains @company-1 or @company-2- We have 1 Exchange 2010 Server Version 14.03.0224.002- Till March of this year our Emails where hosted externally, we used to download the Emails every 2 minutes from POP3 Mailboxes into Exchange- We have 18 Users- So every User had a User account on our Exchange and a Mailbox externally- Now we host our Emails our self via MX and DNS Records(mail.company.cc)- The User kept their Exchange accounts, OWA is now working too So far all works well on my little Server farm.The Catch:Usually our users have only one Email address either @company-1 or @company-2 Except our Boss and one other User, they have an Email address in both Domains They have addresses one...
This topic first appeared in the Spiceworks Community

Hi,
I suggest to repair .ost file to check this issue by the following steps:
Exit Outlook.
In Control Panel, click or double-click Mail.
In the Mail Setup dialog box, click E-mail Accounts.
Click the Data Files tab, select the Exchange account, and then click
Open File Location. A file explorer window opens to the location of the data file for the Exchange account. The
Account Settings and Mail Setup dialog boxes will remain open, behind the file explorer window.
Close the Account Settings and the Mail Setup dialog boxes, then return to the file explorer window.
Important: be sure to close these two dialog boxes before you delete the file. If they aren't closed, Windows may display an error message about a conflict.
In the file explorer window, right-click the Exchange data file and then click
Delete. The next time you start Outlook, a new .ost file is created for the account.

No rules in outlook
No Auto archive

Hi,
Can you see the missing emails from OWA?
Have you tried to start Outlook in safe mode to check if any third-party add-ins caused this problem? To do this, press Windows key + R, type
outlook.exe /safe in the Run dialog box and press Enter.
If the issue would be gone in safe mode, please disable suspicious add-ins referring to the following article:
http://office.microsoft.com/en-in/help/enable-or-disable-add-ins-in-office-programs-HA010034127.aspx
Please also check if your virus scanner is integrated with your Outlook. If so, disable it to check the result.
If possible, we can try to create a new mail profile in control panel to check if the issue persists:

Surface + Outlook 2013 + Exchange 2010 + VPN Problem

Ok so the Surface with Outlook 2013 works fine with our Exchange setup when the machine is attached to the network directly. Once it is on an external network and attached via a VPN connection it ceases to operate, and attempting to run Outlook simply results
in a box asking for credentials, which even when typed in correctly are not accepted.
We use many other laptops that are running Windows 7, and a couple that are running Windows 8.1 in the exact same manner, and they operate without issue.
Any ideas?

Hi,
May I first know your Surface version?
If you are not using Surface RT, I suggest you try this:
In Outlook, go to FILE -> Account Settings -> Account Settings -> Double click on the account name -> More Settings -> Connection -> Exchange Proxy Settings -> We can find under "Proxy authentication settings", there are "Basic
Authentication", "NTLM Authentication" and "Negotiate Authentication", I suggest you try "Basic Authentication", then click "OK". Other two authentications can also be tried if the "Basic Authentication"
doesn't work.
I hope the information is helpful.

Outlook 2013 / Exchange 2010 Calendar Invitations blank on recipient side

We have Exchange 2010 and Outlook 2013 for our clients. When our users send calendar invitations to external recipients, some of the recipients are receiving regular emails just containing the notes field and subject. Specifically, when we email
a @hotmail.com or @outlook.com address this occurs. However, when we send an external calendar invitation to @gmail.com, the recipient can see it as a calendar invite and reply with an accept/tentative/decline.
