Retrieving COM class factory for component w/ CLSID failed, error: 80040154

Question:
I get this error when using an ActiveX component in ASP:
Retrieving the COM class factory for component with CLSID {A46E5261-AA56-4767-88CA-DFCED050D09E} failed due to the following error: 80040154.

Answer:
The 80040154 error is a "class not registered" error. Try re-installing the component to make sure it's registered. Optionally, you may register the WebMail2.dll using regsvr32.exe instead of re-doing the install.
