An acronym thats used most commonly at our office is 'OOO' which stands for Out Of Office.
This is used across at all levels, when person leaves office during ''official working time'', which is 9 AM to 6 PM.
A mail is sent to all the concerned, with 'OOO' in the subject and an 'eom' (End of Message).
A few samples
OOO - after 1pm today - REACHABLE ON MOBILE (eom)
OOO after 5.00 PM today (EOM)
OOO for an hour and will be back to office - EOM
OOO from 1:00 PM to 2:30 PM -- Reachable on Mobile ----- EOM
OOO from 3:00 PM today
OOO on 03/08/2007 and 03/09/2007.
Now you get the concept ???
