[Evolution] Archive function

[Bradley G Ward <barnoo bigpond com>]

Hi everybody
Can anybody tell me how to utilise the button on the top tool bar that
says"Move selected messages to the archive folder for the account"?  I
do not have an archive in my folder list by default, creating one does
not make this function usable.  I can't see this mentioned in the
"Help" anywhere although it may be in there somewhere.  I am using
Evolution 3.28.5 on Ubuntu0.18.04.1.

Thanks for any help that may come my way.

B
