I'm out of the office until Monday 28th February 2022

I'm under the impression that you're out to get me, so I've left the office until Monday to avoid whatever it is you're planning. 

If you need anything while I'm away, you should contact Carolyn. 

I say "anything", but of course my premature return is off the table. 

I'm out of the office until Monday 7th February 2022

There's a very low probability that I'll be in the office before Monday 7th February. It's so unlikely, that you'd be wise to assume I'm not there.

If you need anything while I'm sure to be away, you should almost certainly contact Jo, who is definitely excellent.
