Irritating one-sided policies by Microsoft applications ...
When you launch MS outlook it performs some action that may be really irritating... one of this is that it changes the default mailto action and associate it to outlook. I actually have 2 email clients on my desktop, we are migrating to outlook from novell groupwise, and I want to use groupwise until migration is complete... but once I launched outlook... no more mailto.... I've tried with several configurations such as the default mail application, but none has worked. So I've decided to change the mailto association directly inside the registry:
Go to HKEY_CLASSES_ROOT\mailto\shell\open\command
Change the value of the (Deafult) string
For outlook it may look like this: "C:\PROGRA~1\MICROS~2\OFFICE11\OUTLOOK.EXE" -c IPM.Note /m "%1" for Novell groupwise it is something like that: C:\Novell\GroupWise\gwmailto.exe /%1
