meaning of the symbols in sent items folder display

[nguzeldere]

Hi, I could not find information about the symbols seen on the sent items
folder display. For example some messages have an envelope figure with a
circled letter i on the envelope. Where can I find a list of descriptions for
sucy signs? Thanks in advance....

This means that the item contains additional information like for instance
tracking information. Open the message by double clicking it to see the
additional info.
