No contact from Microsoft but it seems the majority of the targets are US based. So long as you keep MS updates regularly installed you should be ok. You can find out more here to check how secure your setup is:

Hi if you are referring to the latest Microsoft Exchange hack in the news this week.

Microsoft Exchange online as part of 365 is not affected.

The affected versions are all on premises versions;

Microsoft Exchange Server 2013
Microsoft Exchange Server 2016
Microsoft Exchange Server 2019

A defence in depth update for Microsoft Exchange Server 2010 has also been released. Organisations running an out-of-support version of Exchange Server should update to a supported version without delay.

Follow the advice here if you have on premise Exchange

if you need anymore help please message me.

Best Regards

Enabled multi factor authentication and you will have greater protection.

Strangely I received a Microsoft text message yesterday with an authorisation code. So someone has tried to change something but have failed.

As above, I would highly recommend using authentication with an app (such as Authy or Aegis) where you need to generate a code.

Text message authentication is risky.
