Exchange 2010 - Unable to verify account information


  • I am getting the same error on my newly installed Exchange 2010 "Exchange Account Unable to verify account information." My existing Exchange 2003 is working just fine using different URL (i.e.,  The new Exchange 2010 has a url of

    Someone posted that they resolved it by removing the OWA redirection on exchange 2010.  How do you this? This may fix my problem too. Thanks!

    I solved the problem by resetting virtual directory in CAS and creating a brand new Activesync.

     Thank you for reply.

  • Could you please paste the output of Get-OWAVirtualDirectory |FL?

    Also, do you have any page redirect enabled on CAS servers?

    Could you please check the application log on CAS servers to see any related errors?

    Is this a problem with all users? If yes where are their mailboxes, Exchange 2003 or Exchange 2010?

  • Hello Mr. Naphade,

    Here's the information.

    I did redirect  OWA to so that I can allow my users to still connect to my exchange 2003.  This works after I enable the form based on exchange 2003. 

    No errors on application log

    The active-sync on iPhone does not work to all users on Exchange 2010.  Users on Exchange 2003 still works using the external url.

    Current external URL on Exchange 2003 -

    Current external URL on Exchange 2010 -

    Everything is functioning on Exchange 2010 (i.e., Outlook, OWA, email flows) except for Active Sync.

    Note: I replaced with our domain name.

  • Just to follow-up on the Exchange 2010 Standard/iPhone 4 error:  "Exchange Account - Unable to verify account information." 

    Could the problem be that I don't have a 3rd party trusted certificate like Verisign? Can the self signed certificate work on iPhone 4?


    When I perform the the error relates to SSL Certificate.

    Certificate validation failed.

  • This could be one of the reasons why iPhone is kicking you off all the time however. I would recommend try turning off your redirection of OWA page for some time and check what happens.

    I was looking at Exchange2003Uri value in the OWA vdir configuration and that seem to be okay as far as your mailboxes are on Exchange 2010 already. You might also want to trust the internal CA certificate on your iPhone store. Keep us posted about how it goes.

  • Hi,
    Here is my suggestions to you.

    Configure the right Exchange2003Url on the owavirtualdirectory
    Set-owavirtualdirectory owa* -Exchange2003Url

    Change the IP Address for so that it has the same one as Today it has the same IP as webmail.

    FBA Authentication doesn't seem to be configured on Exchange 2003. Make sure it is!

    For ActiveSync to work, you need a trusted certificate. That is also true if you are using Outlook Anywhere.
    I wouldn't get a SAN Certificate from Verisign, cause I think they are overprized.
    You can get a UCC certificate from Godaddy for 216$ (3year) and the names you seem to need is

    Common Name:


    DigiCert has a nice tool to create the Certificate request that I recommend you to use.
    DigiCert's Exchange 2010 CSR Tool

    And last but not least, remove the redirection you have configured in IIS on the Exchange 2010 Server

  • After performing the above steps indicated by Ms. Martina, problem still the same - Unable to verify account information on iPhone 4.

    This problem still exist on newly installed Exchange 2010 and coexistent with Windows 2003/Exchange 2003 server.  All is working fine except Active Sync for users on Exchange 2010 database.  Users on Exchange 2003 are working fine so as Active Sync on Exchange 2003.

  • Hi Relfe,
    As far as I can see, you still don't have a trusted certificate installed.

    Have you run ExBPA?

    I solved the problem by resetting virtual directory in CAS and creating a brand new Activesync.

     Thank you for reply.
