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:
- A recent CU update has been applied without a matching version of Messageware Software
- A recent CU update has been installed without running the CU installer with proper elevated administrator permissions
SOLUTIONS
- Check for an update from Messageware by accessing our support download page
- Check release notes for the currently installed version
- If a Microsoft CU Update has been installed without running the installer with elevated admin rights, please uninstall the update and reinstall with the correct permissions
