Almost any test is affected by this - from a list of 45 tests only two
completed, two more with a little help and increasing the server timeout to over
three minutes.

MWS tests are currently running and have a significantly better score.

I can provide a testing environment, more information can probably only be
gathered by debugging the office code, i already discussed the matter with GH
once but without any usable result.

Symptoms (taken from the test-logs) are:
- Server timeouts
- unknown variable "try" (from try-catch-block)
