(Modifying the title to provide clarity)
I have edited multiple rules in Outlook for Mac and when trying to save the changes I get this error message:
"Rules could not be saved because there is an error in the rules. Edit the rules, and then try to save the rules again."
What? I mean WHAT???
Firstly, I have edited the rules in your UI and clicked OK after each edit, how can there be an error?? Why did you not check for errors when I pressed the OK button? How is it even possible that your UI lets me create a rule with an error, it is not a programming language, it is a user interface!
Secondly, what an ignorant unhelpful error message is this? What is the error? In which rule it is? How do I fix it? The message could have equally read "F... YOU!", it would be equally unhelpful and rude!
Not only did I have to abandon all the changes I made, you have also ruined my day!
I HATE YOU TOO MICROSOFT!!!
