What does the Exclamation mark in a message's details in the list column for a folder mean

When I click on a folder, the list of emails in that folder shows what’s in it. No problem yet.
One of the emails in that list has an exclamation mark in the bottom right corner of the detail box in the list of mails. What is that exclamation mark for, and how do I get rid of it?
Otherwise, love the program!

Hi Daniel, this option indicates the message was marked as Important. However this is a user feature, you can mark all your messages as important too, just click on the exclamation mark while composing a new message.

Hope this answers your question.

Hi Paul,

Does that mean the sender is marking them as Important? Is there any way I can get rid of it on received mail?

Hi, yes, it means the sender is marking them as important, unfortunately there’s no option to delete the important mark.

Thank you,
Paul.
