Problems with Exchange Profile

Hi,

i am sorry for my bad english, i hope you recognize my problem:

We have a XI 2.0 with SP3 installed,

now i need to change settings in the Exchange Profile via <http://host:port/exchangeProfile>, in the past with SP2 no problem so far.

With SP3, if i try to save a changed value, the value is not replaced, if i try to import a new profile there is the same effect.

Is there anybody who had the same problem?

Many thanks in advance!
