UK and US Editions of 365?

Hey folks,

This is going to be a bit of a strange question, but we'd recieved advice regarding some M365 settings, we had bother finding details about what they were telling us, which resulted in us being told that it's probably a difference between the UK and the US editions, that they had been reading from the documentation from the US version.

I've had a look online (as you do) and could only find comparison tables between E3/E5 editions and such, just need some confirmation on what we're seeing so far.

Thanks much all.
