For months the Exchange module has successfully committed and flushed the
log files from the server. Recently the Exchange log files have not been
flushed from the server despite the fact that the backup flags no errors
and reports everything as successful. I have re-created the job and checked
that I am using the "FULL - flush & commit logs" option in the Exchange tab.
I can not see what else I am doing wrong, does anybody have any ideas?
