Why OOF and not OOO?
Heh, I’ve wondered about this for years but never took the time to dig into it. When referring to being out of the office, why does it get shortened to “OOF” and not “OOO” as seems logical?
Like most things, it turns out this is a legacy from a previous technical definition. According to the Exchange Team Blog:
OOF was a command used in the days of Microsoft’s Xenix mail system, which set a user as ‘Out of Facility’ - ie Out of the Office. The usage of the term ‘OOF’ just stuck.
