It would be VERY useful to have a synchronizable calendar between various desk top and mobile devices. Thank you!
Yep, I need a calendar too. I'm on O365 and want to switch it over completely to Protonmail, but lack of calendar prevents it.
Yes, I've de-googled my phone this week and am doing well with all alternatives other than calendaring. If protonmail had a calendar that could sync with the android's google calendar (which isn't signed into google with), that would be fine if you don't want to add a protonmail calendar itself. Thanks!
This is one of the many features we need to move completely away from G suites with customized domains.
