The server likely does not have Microsoft Outlook installed. The Outlook Object Library requires Outlook to be installed (and often a mailbox configured). On servers, prefer using Exchange Web Services (EWS) or Graph API instead of the Outlook COM object.

Method 3: Register the DLL Manually (If File Exists But Is Unregistered)

Sometimes the file is present but its COM registration is corrupted.

  1. Open Command Prompt as Administrator.
  2. Navigate to the Office16 folder (adjust for your bitness): 
    cd /d "C:\Program Files\Microsoft Office\root\Office16"
  3. Register the Outlook library: 
    regsvr32 OUTLVBA.DLL
  4. You should see a success message: “DllRegisterServer in OUTLVBA.DLL succeeded.”
