How do I mark emails that I have replied?

[Guest]

In my Outlook, in the flag status column, the flag status showed in my Inbox
the messages I had repllied. I accidentaly remove/delete it and now I can not
find the way to put it back. Thus, I have to go to "Sent emails" to check
what emails I have replied which is to time consuming.

I would like to know how I get the flag status column back and how to set it
in such way that the emails I have replied are showed/marked/distinguished as
already replied.

Thanks in advance

Right-click on the column headers and use Field Chooser to add whatever
column you want.
