Just Start and then run and then logfiles. Look for the appropriate website folder and access the log.
is it using a full domain name ? especially after it goes wrong.

you could probably get away with using just webmail as your DNS suffix should be set up to tag .companyname.com onto any address that was not resolved.  This could be working on most machines but a few might not have the suffix set and so would not resolve it.
