"There was a problem sending this message. Please try again later."
Thanks for the useless error message, Office 365. It would be nice to have an option to see what the problem is.
Is it with the recipients' servers? (Many different recipients have this problem, so I am skeptical....)
Is it with your server? (I know you don't like to admit problems....)
Edit: it would be nice to save the message as a draft but it doesn't give that option.
