Posted on 2023-03-28 by guenni

[English]Microsoft has just unveiled a new security policy for Exchange Online that can block the acceptance of email from insecure on-premises Exchange servers (in hybrid environments). The administrators in question will receive a notification that the on-premises Exchange server is vulnerable.

In the future, this will primarily eliminate systems with on-premises Exchange Server 2007, 2010 and, from April 2023, 2013 that have fallen out of support.

[German]No, it's not an April Fool's joke – it's still March. But as of April 1, 2023, Microsoft's cloud offerings will simply become a bit more expensive. True, it had already been announced in January 2023 – no one really took note of that either.

Posted on 2023-03-24 by guenni

Windows[German]A German blog reader contacted me the other day because he noticed a very crude effect under Windows 10 and Windows 11 in his enterprise environment.

I'll post this case here in the blog – maybe someone from the readership knows something about it or has an idea why the described effect occurs.
