We have tried various things such as using the inbox repair tool on

still the discrepancy between the size on the exchange server and the
local data. Has anyone come across this problem before and what
solution is there to this?

There will usually be some discrepancy between the mailbox and the OST sizes
which should become more aligned after a syncronization, but I doubt they'll
ever match.
