Now, a query arises that why “Outlook could not start last time” error occurs? Well, this issue usually arises with installed Terminal services that are running currently. As Outlook starts, it generates the following key in its registry:

HKEY_CURRENT_USER\Software\Microsoft\Office\10.0\Outlook\Resiliency (HKCU)

If there is no problem during startup of MS Outlook, this key becomes deleted automatically. Otherwise, if any error is detected in Outlook startup testing, subkey under resiliency becomes created and Outlook prompts same warning message as stated above.
Sometimes while the terminal server is in install mode, any program deletes subkey from resiliency key and this key is copied to down mentioned the location of HKLM:

HKLM\Software\Microsoft\WindowsNT\CurrentVersion\TerminalServer\Install\Software\\
Microsoft\Office\11.0\Outlook\Resiliency

Now, when again Outlook tries to access the key via Terminal server application mode, it finds it missing. Then, Outlook search for the key in HKLM and when it gets TermSrvCopyKeyOnce under Resiliency, it replicates the resiliency key again into HKCU.
Therefore, Outlook always searches for the resiliency key and after getting it, Outlook prompts the same warning message.
