When Exchange server is installed a virtual directory called Autodiscover  is created. After the app

Exchange Server serious vulnerability reported

A Security Researcher named Dirk-jan Mollema has recently discovered a vulnerability that affects Exchange and described a way that this vulnerability can be exploited to allow an attacker to obtain escalated privileges. The attack relies on two key components to be successful. Firstly by using a man-in-the-middle attack method against an Exchange Server to perform an NTLM relay attack ( an attacker intercepting the authentication process).

How to find who plays with Exchange Objects

One of the audit tasks that you may need to do while your operation on exchange server is how to find out by whom and when an Exchange Object was Created, Modified, or deleted mainly for troubleshooting purposes.

Disk gets full while migrating to Exchange 2016

A common issue when migrating to a new exchange version is the exhaustion of the log space resulting migration failures. Of course you can not simply go and delete those files because this will lead to more problems than the original one. One migitation to this problem is to run a full backup in order to clear the files and release the space.The other way is to enable circular logging which can be done before you start the migration in order to prevent the problem from happening in the first pl
