I have to use Office 365 for work so there’s no alternative but I think these ads are just for the non-enterprise version? I use Thunderbird for private use but tbf, I send like 2 emails a month at most. Are there many people that use outlook daily for private use?
I’m not sure what most of this means or how it could affect me, but you’re saying that as an EU citizen, this is not something I should be overly concerned with?
