Well, Finally – here comes the complete article of howto deploy office without having Outlook as the default mail client
If you have deployed Office, you probably deployed it either with Outlook or without.
However, if you deployed it with Outlook – you probably wanted Outlook as the default mail-client. This isn’t the case for everyone, and that gave me a headache a while back. Loads of registry hacks and work later (and more work later on) I solved the issue thanks to a techician writing a bat-file resetting the registry keys.
Now I saw this blog-post where the Office Resource team actually will publish an article on howto resolve this automagically.
I wish I had that one year ago.
