Email and calendar separately
 

Up until now I've been using email services that have integrated calendars - such as Google, Fastmail and Outlook. It sometimes occurs to me to move my domains to one of the very good 'email only' services.

If I did change to 'email only,' is there any smart way to work with a third party calendar so that invitations, meeting details, events etc get easily entered into a calendar? I'm thinking primarily of online services.

If so, what might that calendar be?

Is this even a thing?

I know you've edited your post to clarify, but I'm not exactly sure what you want to accomplish.

Are you saying, for example, because Fastmail has a calendar you would prefer not to use it?

If you are wanting to use an online calendar that is separate from your email, I would suggest moving your domain registrar to Gandi - they offer 2 x 3GB mail accounts free, and with that is included - if you use the SOGo interface - an online calendar.

Thanks, Fredonline and sorry not to be clear.

At the moment I am very happy with Fastmail and like the calendar very much and use it. It occurred that some time in the future I might want to/have to move away from Fastmail. I *think* there are some good email hosts that don't have calendars. It's possible I'm wrong here.

If I had to use one of those, then how do I link it with a calendar?

(The more I think about it the more I realise the question is dumb!)

Yes, Gandi would suit well if ever I came away from .Fastmail. :(

If I'm understanding you, what you want is to be able to send and accept email calendar invitations and have your calendar automatically updated, as happens with Fastmail.

I can't answer with complete authority but I would be very surprised if you could find a webmail service that would support remote calendar updates. If you happened to be using a client (that supports both email and calendar, such as Outlook) then I think it's pretty likely you could make that work with distinct email and calendar services.

In the Apple eco system Mail and Calendar are separated.

A cloud based calendar comes to mind, but I am not sure if it will work out for you.
I am using mainly Thunderbird across several computers, Linux and Mac.
Using a free nextcloud account at woelkli.com, which includes a calendar function.
Also "To-do"-calendars.
I am not getting/sending meeting invitations though, but I don't see shy this should not work with Thunderbird with emal set up.
Syncing nice between all computers (and mobile devices too btw)

Many thanks, Reader. I think I could probably make something of that.
