Thanks. I played around with the message text and realised that if my message
got too long, this error message pops up. Do you know if the message text is
restricted to a certain number of letters?

I think you've already answered that question through your own experimentation. Trust your results!

Also, the formula I've used: ([country] "other") OR ([other country] "")
didn't work. I tested the form in 'run this form' mode and I chose 'other'
from the[ country] drop down list but the form did not prompt me to enter
something in the [other country] text field. Is there is mistake with this
formula?

Outlook will prompt only when you save the item with Country = "other" and Other Country blank.
