New Outlook is good, both for yourself and 766 third parties.
@Shrigglepuss I wonder how up to date that 766 number is… just one external party would make me uneasy, 766 makes me want to scream…
@Shrigglepuss BTW, is that for the Outlook Web Application, or the Outlook app? Because if it is the latter, I want to send them to the GDPR faster than you can say cheese…
@juandesant It's the new app they're beginning to roll out to everyone to replace the old Mail and Calendar app (and regular Outlook I think, but not looked too deeply into it yet)

@Shrigglepuss OK, but this is Windows only for now, right? Using Mail.app and Fantastical on macOS because I hate the new Outlook with a passion…

It is a pity the old Outlook Express for Mac (which was based on the Claris Emailer codebase, if I’m not mistaken) was lost…

@juandesant I thiiiink the new Outlook is just a progressive web app under the hood so probs also coming to macOS too
@Shrigglepuss The new Outlook severs you up with email adds, stopped using it when it incessantly kept trying to beg me to change new outlook. Now using Thunderbird as my mail client.
@Shrigglepuss @juandesant The New Outlook is a web app and that's why you see that window: it puts a lot of data on Microsoft's servers. Probably it will substitute the old Outlook for Windows and Mac but that depends on reactions by corporations: they hate radical changes in UI and like to manage their data.
