Mac Mail 'automatically' synching with a Hotmail account..?!

[AliceMac]

Hi folks,

I was surfing just now, and hit a 'contact us' button on a website, which automatically loaded my Mac's Mail software as the default application to send the mail (a thing I've seen happen before), and, lo and behold, my ex-bf's hotmail from about the last three years started to load up into it (inbox and sent)! We used to live together and he used to use my Mac a lot, but he isn't that tech-savvy and he wouldn't have knowingly synched his hotmail up with my machine - he must have unknowingly clicked on something quite fundamentally important/inappropriate... Anyway, as all this mail loaded up, I highlighted and deleted it; then it got to about the date we actually split up, I didn't want to see any more, and I just quit the application.

So I guess I have a few questions: how on earth did it happen in the first place; will my deleting loads of his messages on my Mail app be mirrored on his hotmail account globally; is there a way I can disassociate my Mail app from his hotmail (not that I use it, but the temptation to spy on his messages - destructive and pitiful as it is - will, I imagine, rear its ugly head in my weaker moments, and past experience dictates that ignorance is bliss).

Thanks....

Well, setting up a Hotmail account in Mail is easy, literally just type in your username and password and you're done, as is the case with most big email providers; Mail already has configurations for all the big ones. If you just go into Preferences, Accounts, select his account and then press the small minus button underneath that box, it'll delete the account from your computer without affecting his account online.

...it's that simple? Must be what he did without realising it - easy to imagine him doing so

Thanks for the help!
