BlackBerry (BIS) users not working after upgrading Exchange Server 2007 SP2 to SP3

Hi All,

I got a chance to work on one interesting issue last week.
The client upgraded his Exchange Server 2007 SP2 to SP3. After upgrading it to SP3 everything was working as it should be, except all there BlackBerry (BlackBerry Internet Service) were not getting Synced and they were getting the below message when they were entering the password.


I reset the password in AD and tried it but they were not working. I created the new mailbox and tried with it but even the new Mailbox is also getting the same error message.

One interesting think I found that when I Enabled the Windows Authentication on OWA Virtual Directory it worked fine for one day but it failed next day
By default Windows Authentication on OWA Virtual Directory is Disabled.

But at the same time when users are using OWA they are able to access the mails.
First i thought that it couldn't be OWA Virtual Directory, but after doing some research found that the problem is with OWA Virtual Directory.

Recreating the OWA Virtual Directory resolved the issue
New-OwaVirtualDirectory -name "owa" -OwaVersion Exchange2007 -WebSiteName "Default Web Site" –InternalURL https://internalURL/owa -ExternalURL https://externalURL/owa

Issue Resolved :)

Cheers,

    Do you mean to say, How to recreate OWA Virtual Directory?
    If you already have OWA Virtual Directory than first you will have to remove it by running the below command.
    Remove-OWAVirtualDirectory -Identity "Owa (#######)" -Confirm:$false

    Once you removed it, than run the command to recreate it:

    New-OwaVirtualDirectory -name "owa" -OwaVersion Exchange2007 -WebSiteName "Default Web Site" –InternalURL https://internalURL/owa -ExternalURL https://externalURL/owa
