A fatal error occurred when attempting to access the SSL server credential private key.
I have faced the following error at a client when trying to setup a Forefront TMG 2010 array in a work group environment, however this error is not related to TMG itself so you might encounter it in any setup when your server is using Certificates for server authentication.
When building my Forefront TMG 2010 Array the server designated as configuration storage started logging in the the event log the below error every other minute, I did try to issue another certificate for it and even uninstalled and installed TMG again but nothing did the trick.

A fatal error occurred when attempting to access the SSL server credential private key. The error code returned from the cryptographic module is 0x8009030d. The internal error state is 10001.
The solution to my problem was granting the Network Service Read permission on the certificate and this is how I did it
Cannot open outlook 2010 ost file is in use
For some reason recently I started to get the below error while loading my outlook profile. Even though nothing was changed with my laptop configuration.
After digging the problem I have noticed that this behavior is not the same every time I open my outlook profile but It was whenever I am trying to open outlook after having the "Lync client (RC)" running, so what I had to do is that exit the Lync client and end its process if it was running then open outlook 2010. this worked for me.
I have also noticed precisely that this issue is occurring if you close outlook client before system hibernation.
Technically Lync client uses Outlook to sync contacts and as part as of the Office-Lync Integration , so apparently the Lync client is locking the OST file while it is running.
