I've just moved into a new job at a new company, one that relies heavily on Outlook. I've never used Outlook on an Exchange server before, and I prefer an analog GTD implementation. Given that I'm pretty much required to use Outlook, I'm wondering whether to migrate my entire system, both work and personal into Outlook. My concern is, how secure is Outlook? Should I be worried about others gaining access to my information? I know I can set events as "private" and such, but what about personal projects, tasks, and contacts?
Unfortunately, I'm not able to install any software on my work machine, so the GTD plugin and other Outlook extensions are a no-go. I'm still coping with returning to a "traditional" file system without desktop search.
