How to troubleshoot the Outlook IM integration for VDI

After uninstalling the Zoom desktop client (including the Zoom VDI Client), my Skype for Business integration stops working.

  1. This is a known issue for Zoom desktop client versions older than the 5.6.6 release and Zoom VDI Client versions older than the 5.5.8 release.
  2. This problem can also be fixed if you install the latest version of the Zoom desktop client or the Zoom VDI Client.
  3. If the user must use a Zoom VDI Client version older than the 5.5.8 release, then run the PowerShell script to repair.

When I use the APPV to deploy the Zoom VDI client after I upgrade to a new version, the Zoom Outlook IM integration does not work.

Can I deploy two different APPV Zoom VDI clients at the same time?

When I use the APPV to deploy the Zoom VDI client, after upgrading to a new version, my Skype for Business Outlook integration does not work.

  1. Ensure that you unpublish the older APPV package before publishing the new APPV package.
  2. Check if you have a mechanism to back up and restore the HKCU registry keys. It could cause the Skype for Business Outlook IM integration function to be broken because the wrong HKCU registry keys are restored, as it points to a non-existing Zoom APPV package location.
  3. If a problem happens, run the CleanZoom tool (updated November 30, 2023) on the impacted system.

Use the CleanZoom.exe for recovering HKLM/HKCR/all users' HKCU registry keys

Use the script skb_repair.ps1 for recovering HKCU registry keys

  1. Download the skb_repair.ps1 file. 
  2. Start PowerShell as an administrator.
  3. Run “set-executionpolicy unrestricted” in PowerShell, and type "Y" to allow this setting.
  4. Run "&.\skb_repair.ps1" to repair HKCU.
  5. The log is in "C:\temp\skb_repair.log".
