First off, if the co-worker's e-mail made them look stupid, they deserve to know they are retarded...
#2- Outlook still lets you recall e-mails. You just open the sent e-mail and go to "other actions" on the action tab and recall message.

Oh No! The OPs life is totally fucked now! There is no way that they will ever recover from this! /sarcasm over/

Learn to read OP.

Don't you check the subject field of an email? Usually emails will have "FW: ___" if you're forwarding, or "RE: ___" for replying.

+ I agree with #3.

#1: Not all workplaces use Outlook express. What happens if it's a company email?

+ if you're going to mock, you might as well do it on the phone or at home or whatever. At work? Lol what are you, 5?

And that's why you should pay more attention on the internet

i dont really understand this FML. Seems OVERLY dumb, I mean.... you hit reply FIRST, then it goes to the message, then you write it and push send, of course, ESPECIALLY if your making fun of someone, checking to make sure its going to the right place.

im a twelve year old and i have never mocked an email much less made such a stupid mistake or seen anyone do that
as for you saying 12 year olds act up and all because you assume all twelve year olds do act like that, think again

first of all when u hit reply not happens cuz u are replying to the person that send it.. second y would this be a FML if it wasnt sent... this is just a dumb stupid FML...

Do you know how to write in the English language?
Illiterate.

But your a child.

Pre-teens think they are mature. They are not. And I do know, I used to be one.

Nope.

uh yeah you used to be one, probably a long time ago but you dont speak for every single 'pre-teen' out there. seriously. how rude.
