Solution: Remove resiliency registry key

Resiliency registry key for Outlook is new for Outlook 2002. If no problems are encountered, the Resiliency key is deleted. If one of the many tests that Outlook makes at startup fail, TermSrvCopyKeyOnce subkeys are written under Resiliency key and is not deleted. If the key remains, the next start of Outlook gives the prompt.

Step 1: Open Registry Editor (regedit) with Administrator right.

Step 2: Check if Resiliency key exists: HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Terminal Server\Install\Software\Microsoft\Office\16.0\Outlook\resiliency.

Step 3: Delete Resiliency key if found.

Note: Backup registry key before delete.
