When arranging a meeting using webmail clicking the 'availability' button
results in a '503 Service unavailable' error. (in mozilla)
When using IE you recieve a different error 'the service is no longer
available'

To my knowledge nothing has changed on the server and this functionality
used to work, although I had never used it.

we have a front end backend infrastructure and you reiceve this error what
ever exchange server you go to, be it FE or BE.

Anyones help would be appreciated
