We are applying emergency exchange server maintenance on 03 march 2021 starting from 21:00 CET.

There should be no downtime as the updates roll out redundantly over our exchange clusters.

The emergency updates are to address the recent chain of Exchange security updates released and reported by Microsoft: https://msrc-blog.microsoft.com/2021/03/02/multiple-security-updates-released-for-exchange-server/

Due to the serious nature of the security patches we have chosen to launch the maintenance as soon as possible and not even wait till after midnight.

The updates roll out is expected to last till 02:00 AM 04 march 2021.
