SYMPTOM

During opening OWA page, the following message is displayed:

Internal error: version compat error VCE001

 

CAUSE

 

Messageware has recognized that the Exchange version has changed, and there may be a compatibility issue.

 

Two common causes are:

  1. A recent CU update has been applied without a matching version of Messageware software
  2. A recent CU update has been installed without running the CU installer with proper elevated administrator permissions

 

Solutions

 

  1. Check for an update from Messageware by accessing our support download pages
  2. Check release notes for the currently installed version
  3. If a Microsoft CU update has been installed without running the installer with elevated admin rights, please uninstall the update and reinstall with correct permissions
