Server timed out, Server busy errors in OWA. Have had it from a random number of users its not consistent or repeatable that Ive seen.

we use the same FQDN for both internal and external owa access (mail.blah.com)

Most of the reports are from folk accessing from external as we use outlook 2010 internal (no problem with outlook either internal or external)
