If you want to ensure that it will work for any version of Outlook, consider
using late binding as described here

As for your second question, I don't know how to find the default mail
client. I saw the same question a couple of time using Google, but none of
them were answered.

I have made an application where I send Outlook e-mail via Excel. Since
I don't know what version of Excel the user has I need a way to find the
correct reference to the MS object library.

I have seen a reference to a general "obl" that works regardless of
Outlookversion. Does anybody know where I can find it?

How can I check what mailprogram the user is running as standard,
Outlook or Outlook Express? Depending of answer I will use different
code to send mail. If the user is running a mailprogram other than MS I
would like to end the process with a message to the user.

Thanks in advance
