I hate Thunderbird.
Mozilla Thunderbird has email, address and calendar function.
As already mentioned for PC Mozilla Thunderbird.
For Android you could take a look at K-9 Mail. For Apple I have no idea
K-9 is Thunderbird Mobile these days. I used to use K-9 but switched to FairEmail. Which incidentally is both open source and European (but doesn't have calendar and contacts - would rather have separate apps for those anyway!)
As Android phone have an integrated calendar functionality and a calendar app, a DAV connector like DAVx5 would then be used to connect to cloud calendars and contacts.
But Mozilla is American right ?
Unlike MS Outlook, Thunderbird is free (as in free beer and as in free speech) and open source and it is a community-driven project. So it is less important where Mozilla Foundation (or their subsidiary MZLA Technologies Corporation) is located.
For Apple it is best to stick with the native e-Mail client Apple mail.
However, this is only mail. Then other things would need caldav and carddav servers.
What do associate with outlook? The complete online suite or the e-Mail programm only? What about calenders and notes?
