This is a terrible Service Pack, like many other I am experiencing some very serious problems after installing SP1.
Cannot open the EMC, big problem!
Not even got to the other potential issues that others are experiencing.
There is a lot of code to check, this is obvious, however to release a much anticipated Service pack which creates so many issues is quite unbelievable, doesn't matter how many lines of code need checked, very very very bad...
I have been trying bring a case to Management for us to upgrade from Exchange 2003 to 2010, this makes it practically impossible for anyone to make a case for upgrading.
I am using virtual machines for my test lab, nice that I can just roll back.
Can't say how bad this is...
Poor poor job...
