I usually deliver Microsoft official courses around Europe, related to Windows Server, Exchange Server, System Center, Azure, etc.
You can take a look at the live scheduled courses here: https://systemplus.gr/
However, there is another option: you can attend my video courses through the https://mcse.gr/ web site. You get the exact same benefits as in a live course (minus the live instructor, of course): Microsoft official courseware, Microsoft online labs and the ability to watch the course videos unlimited times, in high-def format.
In case you don’t want to pay, you can try to attend my recorded webcasts here: https://mcse.gr/trainingvideos.html
