A company with a 4 trillion dollar market cap can't be bothered to perform some basic testing of OS updates against major enterprise apps like Exchange ? This wouldn't be acceptable even for a small startup. There is no apparent awareness of or concern for the outages, grief and impact to business that you continue to cause for support staff as well as end users.
You'd have a hard time convincing most people that have been supporting Exchange for a long time that this wasn't deliberate and that you don't have an ongoing disdain for on-prem users.
The Exchange team provides as little help as possible and sound more like attorneys every year. Strangely, your fanboys continue to say "thank you".
