What do icons next to mail mean?

For example envelope with purple arrow is replied mail, but what about others? I failed to find this in online help.

Hi, what others do you have in mind, the envelope with blue arrow pointing to the other side than the replied one, means the email has been forwarded, but there’s not many more icons, except unread message which is a sealed yellow envelope.

Can you maybe make a screenshot of the other icons you have in mind?

Thank you,
Paul.

Thank you for reply. I was interested in blue arrow because I couldn’t figure what it was, but thanks to you now I know. I’ve tried to generalize my question, so I’m not even sure if any other icons exist.

Ok, I’m glad I answered your question, if you have any other questions or issues with the application, let us know. We’ll be happy to help.

Thank you,
Paul.
