Hi Dev T!
I think you missunterstood my problem - it worked fine till 4th january, then I installed SP3 and the following hotfixes but since this time it never worked.
So the problem is not ho to configure the exchange agent but I think there is a massive bug in SP3 which causes the error.
I also have troubles to backup files on an other server and here also comes the message, that the files are damaged.
But this isnt true, they work fine and chkdsk find no errors.
Both problems consist at the highest drive letter - I read in a forum of an other user who has similar problems.
Exchange DB and Files from the highest drive letter can't be backuped because of error which are not there.
How can I solve this trouble?
Thank you!
