difference between COM Add-ins and Plug-in

[masani paresh]

Hi,

Could any one please tell me is there any differences between Outlook COM
Add-ins and Plug-ins? Also How could I change my VBA macro to Outlook Add-in
or Plug-in? Which language (C# or VB) would be preferable to write this.

Thanks in advance,
Paresh

Try asking in microsoft.public.outlook.program_addins

COM Addins can be written using any language that can support COM automation
and normally use the Outlook object model, although they can use other API's
also.

What you call plugins are written using Extended MAPI and can only be
programmed in unmanaged C++ or Delphi. You also have to know a lot of
Extended MAPI to do anything like that (long learning curve), and they are
probably going to be deprecated.

I'd stick with a COM addin unless you really know Extended MAPI, know C++ or
Delphi, and don't care about compatibility going forward.
