@mhoye I worked at Microsoft for five years. IT departments are as prone to consumerism as mere mortals are.

MS 365 is incredibly slow and unreliable. My self-hosted Postfix/Dovecot is faster and more reliable by a large margin.

Yet IT is told they "need" 365 to "save money" when all it does is enrich MS partners.

Same with "Big Data". People were told they need Hadoop and DataBricks when all they need is Excel or sed/awk.
