How Do I Programmatically Disable/Enable Microsoft Exchange Active Sync For All Of My Mobile Users?

  • Artikel

While working with a customer recently, I created a VBScript that leverages ADO to programmatically disable/enable Microsoft Exchange Active Sync for ALL users in Active Directory.  The key to this script is the msExchOmaAdminWirelessEnable attribute.  If you know VBScript, the code below is very easy to use.  You will need to copy and paste this code into your favorite text editor and save as a .VBS file.  Also, this script needs to run on a domain controller and you will need the appropriate privledges to run it.  As always,you should never run this script in a production enviornment without proper testing in a lab first.   I've only tested this on Exchagne 2003, BTW.  Disclaimer: This sample script is not supported under any Microsoft standard support program or service. The sample scripts are provided AS IS without warranty of any kind. Microsoft further disclaims all implied warranties including, without limitation, any implied warranties of merchantability or of fitness for a particular purpose. The entire risk arising out of the use or performance of the sample scripts and documentation remains with you. In no event shall Microsoft, its authors, or anyone else involved in the creation, production, or delivery of the scripts be liable for any damages whatsoever (including, without limitation, damages for loss of business profits, business interruption, loss of business information, or other pecuniary loss) arising out of the use of or inability to use the sample scripts or documentation, even if Microsoft has been advised of the possibility of such damages.

Start of the script:

    Activesync is often confused for OMA which is Outlook Mobile Access. Outlook Mobile Acces is similar
