I have a need program (emailtemplate/emailtemplates.com) I use in XP with Outlook 2000. The vendor went out of business and sooner or later I will need to update. It uses RegEx to parse a highlighted email and rewrite it in a new email.

I upgraded to Windows 10, but Outlook 2000 would not install.

I tried to install the needed program in Outlook 2010, which appeared to install without error, but it does not show up on the ribbon, nor has it created a folder.

Is there any chance to get this working? A switch to tell 2010 to accept a 2000 addon or something? Or perhaps another application that that allows you to write an email parser and write a new email?
