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.

Andrioid 4.4.4 Galaxy S5 and Exchange 2010 / Active Directory issue

I have posted this here because I don't see a category for Exchange 2010 which is what we currently use and I am not sure where else to post it. Please redirect if needed. Thanks in advance.
I am an IT Tech and I am trying to connect my phone to my email using the standard email application on the phone, with no success.
I was convinced for a long while that it was my phone.
I tried everything I could with the phone and restricting background data and everything but nothing worked.
I type in the credentials and it accepts them and shows me the mailbox but then it never loads the mail and folders.
I must have gone through this process 100 times and occasionally I get a message saying the certificate is incorrect do I want to accept it anyway.
I view the certificate and it is for another domain. When that doesn’t happen I just get pushed from checking the server setting and then it moves right to the settings of the mailbox.
However I don’t get the warning like I did when I created a new mailbox and AD account.
Create new exchange mailbox/ AD account – This worked, but ultimately I want my current user name and mailbox to work.
I don’t want to move to a new one if I don’t have to – I created a new mailbox which intern created an AD account.
After this was done I attempted to sync this account with the phone.
It worked first time without a problem. After the phone checked the server settings it gave me the warning that I was going to have to let the server control the device like it always does.
It also made me accept the System Administrator settings.
I sent a test email to and from it with no problem.
There are other people on our server with Galaxy S5’s and other Android based devices and I have added mail to their devices just like I would my device and they have no problems at all.
I have matched up the mailbox settings and AD settings and everything is the same for the most part.
It is bound to be a little different because I am an IT Tech so obviously I have more than the others, but I don’t feel like additional security should not allow me to add to my mailbox to my device
Other things I tried through the process, with no success, in no particular order are:
Tried connecting my account from different devices
Disconnected and recreated mailbox
Deleted and recreated AD account
There is one thing I noticed in the security tab of the AD account, other people using our mail system and Android based devices have something called
Data Sync. That is some sort of contact in AD
I guess. I cannot find any information about it and when I add it to my security tab, it will not stay.
After I close AD and check back 15 minutes late it is gone.
I am trying to describe this the best possible way. Has anyone experienced similar issue?
If there is any further information needed feel free to ask.

Then I would firstly suggest visiting the Remote Connectivity Analyzer Website to check common availability to your mailbox. Just run through the test.
I ran this test as suggested two different ways. With my user name and password and then a second time with the mail server. Both times in failed all tests with the exception of the following three:
Attempting to resolve the host name in DNS.
Testing the TCP port 443 on host to ensure it's listening and open.
The Microsoft Connectivity Analyzer is attempting to obtain the SSL certificate from remote server on port 443.
All three of these passed. I am not sure what most of this means, but we have people in the company a variety of different devices that connect with no problem. For this reason I believe this problem is localized to my AD account or my mailbox,
I have matched up settings with people that I know have the same device and use it on a daily basis with no problem and can not find anything different.

Exchange 2010 Active Sync issues

I know I've posted a lot lately, but the issues keep rolling in with this upgrade. Since upgrading to Exchange 2010, I have 2 users ( that have come forward thus far) saying they are unable to add exchange mail back onto their phones.
When I go into EMC to look at it and right-click on the uses it shows the option to manage mobile device. Usually when there is no device paired, that option doesnt come up. When I go into manage mobile device, it shows that there is no device
listed. If I run Get-ActiveSyncDeviceStatistics -Mailbox:"alias" I get the same result. It shows no device. I think this is locking the user out somehow from being able to add exchange back onto their mobile device.
I have also tried removing their email box from the server, then re-attaching it. I get the same results each time. They can add exchange to their phones, but when it tries to download mail it gets "Cannot get mail. Connection to the
server failed." Even after they were able to add their account into their phone.

Since you had ActiveSync devices on these accounts on the old system, the tools know those devices existed. However, you can't manage them until you connect through the new system. Is your Exchange 2010 system the one that handles the inbound
ActiveSync connections? Downlevel systems can't support any
mailbox connections to newer systems.

Exchange 2010 address book issue.

We're using Exchange 2010 in our organization. My old database got corrupted so i created new mailbox and add existing users to it. Now the issue is, before users type other usernames in outlooks address bar and mail gets delivered to the recipients, now
they have to select users from "To" list in outlook and have to add them to the address bar, if they type the recipient name rather selecting from the list then the mail don't get delivered. What is the issue? Any idea why this happening?

Hi
As per the information and details provided by you, to solve the problem of address book in Exchange 2010, please follow these steps: -
Enable web-based distribution for the OAB to your client access servers
– If you are upgrading from Exchange 2003 to 2010, this step is a must.
Change the mailbox server that’s responsible for generating your OAB to an Exchange 2010 mailbox server –
This is important whether you are migrating to Exchange 2003 or Exchange 2007.
I hope this information will be helpful for you.
Thanks and regards

Exchange 2010\Outlook Mail issues

Hi,
I am having some issues with mail disappearing and outlook not updating. The issues are:
When sending an email from Outlook it appears in the sent items for 30 seconds in Outlook and then disappears. It never shows up in OWA The email does send though. If an email is sent via OWA the email appears and stays in both OWA and Outlook. This is
happening in Outlook 2010\Exchange 2010
Updating issues on random folders in Outlook. This is happening on both Outlook 2013 and Outlook 2010 different users with the same Exchange 2010 back end.
Both users have cached email forced. I have tried rebuilding the mailbox locally.
Cheers,
Zac Avramides

Hi,
Thanks for your detailed information about the symptom.
It seems the issue is more related to the Outlook client since OWA works fine. I suggest we can follow the checkpoints below:
1. Rebuild Outlook profile.
2. Disable any third-party firewall or AV programs.
3. Run Windows in Clean Boot.
4. Run Outlook in safe mode by “Outlook /safe”.
What’s the result now?
Thanks,

Exchange 2010 calendar sharing issues

I am getting several reports of users not being able to open a calendar shared to them by their manager. I have checked the calendar permissions on their managers computer which all look like they are able to read it.
The manager is using Outlook 2013 to share out her calendar. the users are using various avenues, either on an iPad or through OWA. I'm at a loss of where to check for additional issues on this. Any suggestions or ideas for you brilliant people?

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.

Exchange 2010 Outlook Anywhere issues

I have an Exchange 2010 cas server that works fine with OWA internally and over the internet, and Outlook Anywhere works fine internally. When I try to access it outside the office though, the authentication prompt just keeps coming up for any user I try
it on. I have used the connectivity analyzer, and it gives me what I've pasted below. I have disabled OA and uninstalled the RPC, rebooted and installed again and set it back up, with no luck. I've also tried both NTLM and Basic setups on the server side,
and they both give the same error from outside the office. I also have checked my firewall settings, and everything is good. The only thing I can think of is that my reverse proxy is causing an issue. We have RHEL 5 with apache doing reverse proxy. Everything
else works though, so I'm not sure why OA wouldn't?
RPC Proxy can't be pinged.

Hello
501 is an internal server error.
Please browse RPC virtual directory from outside, and see if you are getting a default response - Which should be a blank page.
If you are not getting a blank page, then you need to troubleshoot that first - May be re-install RPC over HTTP.

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.

Moving an Exchange 2010 VM - Any Issues

I need to move an Exchange 2010 VM from one office to another. Using Live Migration over my WAN link is out of the question, Live Migration to a Windows 8.1 box isn't possible and bringing a host back to the original office is doable but a pain. So,
I would like to export the VM from the current host, transport it to the new site and import it there. Are there any issues with exporting/importing an Exchange VM that I should be aware of?
Thanks
Bert

OK, it sounds like I can try it, then.
I asked because I tried to do an export/transport/import of a DC and that failed miserably. I just wasn't sure if Exchange would puke if I tried it with it. I know that the process works fine with basic Windows boxed but beyond that, I'm not
sure.

Exchange 2010 Mailbox move issue

Hi
I have moved around 100 mailboxes from DB to other DB in the same server.
Now all these mailboxes are in Disconnected state.
The problem is, these mailboxes are appearing twice under disconnected mailbox window. One is from old db and other is from New DB.
The reason for the same shows for Old DB is Soft Deleted and for new DB is Disabled.
IS this a general behaviour? Currently when the user access the mailbox, it says its locked for moving.
How can renable these mailboxes and make user accessible? Do i need to wait till retention period over?
I have set the deleted mailboxes rentention to 2 days. Will this make mailboxes active after 2 days?
regards Sundaresan.C

Yes this is general behavour; Soft Deleted mailboxes - introduced in Exchange 2010 SP1
more info can be found here; http://technet.microsoft.com/en-us/library/dd298174(v=exchg.141).aspx
This example purges the soft-deleted mailbox for Phil from mailbox database MBD01.

Visio 2007 standard and Visio 2010 standard compatibility issues

Have a Visio File that peoplle using 2007 Standard can open and view, but when using 2010 Standard thhe drawing is not viewable, all the drawing properties are there but the drawing can not be seen

Hi,
I have some questions about the issue:
1.Did both of the Visio 2007 and Visio 2010 installed in the computer?
2. If we open and view the file in the different computers, how did you transfer the file? By email, physical storage or the other?
If we had two computers, I recommend you copy all the
content from the special file to new blank Visio 2010 file to test.
If you sent it through Email, the file may be damaged. Please follow the link to troubleshooting the issue:

If the issue still exists, as Mr.Paul said, upload a sample in the thread.

Exchange 2007 and 2013 Co-existnec - ActiveSync Issue

Hi
We have introduced Exchange 2013 servers in our existing Exchange 2007 environment. We have a customized Exchange 2007 ActiveSync setup i:e we created a custom separate website in IIS for ActiveSync to serve the ActiveSync devices. After the introduction
of Exchange 2013 CAS servers, when we installed the new certificate on them and configured the virtual directory with ActiveSync URLs, the Exchange 2013 servers seems to be receiving Activesync requests but they can't just proxy it to Exchange 2007 for some
reason. following Warning is logged on Exchange 2013 servers:
[Eas] Marking ClientAccess 2010 server MIA-EXCAS01.utg.uvn.net (https://mia-excas01.utg.uvn.net/Microsoft-Server-ActiveSync) as unhealthy due to exception: System.Net.WebException: The remote server returned an error: (503) Server Unavailable.
at System.Net.HttpWebRequest.GetResponse()
at Microsoft.Exchange.HttpProxy.ProtocolPingStrategyBase.Ping(Uri url)
We still need to install new Certificate on the Exchange 2007 servers. Wondering what could be the issue here, can Exchange 2013 proxy the connection to Exchange 2007 on a custom website ? or it looks for one under Default Website?
Can the absence of new certificate (meaning certificate mismatch) lead to this issue?
Thanks
Taranjeet Singh
zamn

Actually 2013 can proxy ActiveSync to 2007
Please follow this.
1. Set AutodiscoverInternalURL using this command for every CAS server
Set-ClientAccessserver -identity -CAS1 -AutodiscoverInternalURI
https://mail.yourcompany.com/autodiscover/autodiscover.xml (for FQDN , using your CAS NLB name if exist)
2. Set OWA virtualdirectoy (2013) via EAC
Internal URL : https://mail.yourcompany.com/owa External URL : https://mail.yourcompany.com/owa
3. Set ECP virtualdirectory (2013) via EAC
Internal URL : https://mail.yourcompany.com/ecp External URL : https://mail.yourcompany.com/ecp
4. Set OAB virtualdirectory (2013) via EAC
Internal URL : https://mail.yourcompany.com/OAB External URL :
https://mail.yourcompany.com/OAB
5. Set EWS virtualdirectory (2013) via EAC
Internal URL : https://mail.yourcompany.com/EWS/Exchange.asmx External URL :
https://mail.yourcompany.com/EWS/Exchange.asmx
6. Set ActiveSync virtualdirectory (2013) viaEAC
Internal URL : https://mail.yourcompany.com/Microsoft-Active-Sync
External URL : https://mail.yourcompany.com/Microsoft-Active-Sync
For 2007
1. Set AutodiscoverInternalURL using this command for every CAS server
Set-ClientAccessserver -identity -CAS1 -AutodiscoverInternalURI
https://mail.yourcompany.com/autodiscover/autodiscover.xml (for FQDN , using your CAS NLB name)
2. Create DNS record
legacy.yourcompany.com = your CAS2007 NLB (if exist)
3. Set OWA virtualdirectory (2007) via EMC
External URL = https://legacy.yourcompany.com/owa
4. Set ActiveSync (2007) via EMC
Internal URL = https://serverFQDN/Microsoft-Active-Sync <<<< Using for proxy
External URL =
https://legacy.yourcompany.com/Microsoft-Active-Sync <<<< Using for redirect
5. OAB via EMC
External URL = https://legacy.yourcompany.com/OAB
6. EWS via Exchange shell
External URL = https://legacy.yourcompany.com/EWS/Exchange.asmx
FYI

Exchange 2010 & Ipad Sync Issues

I have a user that started having problems syncing up his Ipad to his exchange account. He has an Android that he can sync okay. He syncs the Ipad okay but the Inbox shows that he has no email. So far he is the only one in our
environment that has reported any issues. About 3 weeks ago I upgraded our exchange environment from SP1 to SP3, this weekend I updated SP3 to rollup 5 which did not fix the issue. Here are some trouble shooting steps I have tried to no avail:
Deleted partnership from Exchange
Deleted phone account from OWA
Deleted account from Ipad and readded - will sync gets message "No Mail" in Inbox
I do notice that when he re-synced no partnership showed up in Exchange or OWA
Made sure Inheritable Permissions box is checked in AD
Get-CASmailbox information matches mine, mine works fine.
I can sync okay on my Iphone, I had him use my Iphone to sync his account and he gets the same "No Mail" message.
