I wonder whether this will help the already strengthening trend of some governments to unstick themselves from Microsoft (in particular their cloud).

I don't expect a fundamental shift but the boss having no access to his mails certainly seems like something I would bring up quite a bit.

I am certain this is the direction of thought at least for Europeans. IIRC France recently moved away from Microsoft. If right now they do not have this outage, I can only imagine how much it boosts confidence in such decisions

It will help a bit, but it would need much more than 24h to have a real impact. If their service is still down in a week, now we're talking.
