Hi, that sounds like more than a simple console shortcut issue. Since both EMS and Toolbox are affected after an Exchange SE upgrade, I would first validate the server health and support state before chasing individual snap-ins.

 

Good next checks:

 

1. Run the latest Exchange Health Checker script and review any red/yellow findings.

2. Confirm the server OS, Exchange build, and installed security/hotfix updates are all supported together.

3. Try opening EMS directly as an Exchange admin from an elevated session.

4. Check the Application log and Exchange setup/update logs for RBAC, WinRM, serialization, or PowerShell endpoint errors.

5. Re-run Exchange setup in recover/repair only if the health check points that way.

 

If you can share the exact EMS error text and the Exchange build number, that will make it much easier to separate an RBAC/PowerShell endpoint issue from an install or update issue.
