It has been a while since I last had following issue:
A user gets a mail in which there is a link to a document on SharePoint (2007 in this case). On most PC's the file opens nicely in the needed Office application... however, on some PC's the file opens in the browser.
What's the solution?
Well luckily, this is something which seems to happen often, so google soon brought me to the right location:
http://www.shaunakelly.com/word/sharing/opendocinie.html (Tnx Shauna).
So, the user has to indicate that he/she does not want 'browse in same window'... and it'll fix the issue.
Reason:
The link you get in a mail refers to the SharePoint site on which the file is stored. Because it's on SharePoint, the first thing the link does, is to open SharePoint (in the browser) to get the file details (such as location in the database). As a second step, it will open the word file... and with the 'browse in same window' checked, that means it will open in the internet explorer window.
