Okay, we had office alternatives, but in none of those I see an alternative for outlook. Is there anything similar? Would appreciate if could you the same on my phone and computer.
Unlike MS Outlook, Thunderbird is free (as in free beerand 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.
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.
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
But Mozilla is American right ?

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?
Sogo.
Its a Web-Client. You host a webserver hosting sogo and sogo instead connects to your mail provider as a client.
Mail, Calendar and Contacts are possible.
I hate Thunderbird.
