“I like Outlook because of its integration with other Office applications.”
That’s a great feature.......if you are a hacker. Send an email, have it fire off a program and BAM pwn3d!
That's not what I'm doing. I'm using it for mailing labels and such. Christmas lists, envelope labels, that type of thing. I send nothing via email from an office application (other than Outlook).
But I do want to import contact information when using Word, for the purposes outlined above. If Thunderbird integrated with OpenOffice, and had all the features of Outlook, I'd be interested.
