Communicated something confused and not up to date? (8)
I believe the answer is:
'communicated' is the definition.
(I've seen this before)
'something confused and not up to date?' is the wordplay.
'something confused' becomes 'mess' (something messy or confused).
'and' is a charade indicator (letters next to each other).
'not up to date?' becomes 'aged' (old).
(Other definitions for messaged that I've seen before include "Contacted" , "communicated" .)
