Shared calendar for phone users

sbrunner

For many reasons I am trying to replace my Exchange Server with Grommunio. I have now installed Grommunio with the scripts from crpb and connected it to the AD. Receiving and sending mail works.

Now the issue is that my wife still wants my calendar on her cell phone... What is the best way to share the calendar with another user?
So far I have done this under Exchange with a Webcal share. Is this also possible with Grommunio?

Thanks for any advice...

Hey sbrunner, as i think you only have so many (a couple users) you can for one use a public folder for everyone

Of course that isn't your private one..

Another way would be an additional mailbox(with login) you both use or as it's like your boss you could just add the mailbox to her phone and only sync the calendar.

Or you could add an an additional DAV Calendar which she would only need her logindata for as shared calendars/contacts are visibile with that connector.
https://your.gromi.host/dav/calendars/yourmail@domain.tld/ (you have to manually provide the mailbox as only the public folders are visible besides your own)

Thanks for your suggested solutions.
I find the approach of using caldav to access the shared calendar interesting.

However, at the moment I am still struggling with the server giving me a 404 error when I try to access to the shared calendar:

==> /var/log/nginx/nginx-dav-access.log <==
172.16.2.4 - user@domain.tld [20/Sep/2024:20:56:00 +0200] "OPTIONS /dav/calendars/user2@domain.tld/Kalender/ HTTP/1.1" 200 0 "-" "curl/7.54"

In webmail and Outlook it works as expected. I don't seem to have the authorization in caldav. Do these have to be assigned separately or is there another error here? I can't find anything in the docs or the forum.

thanks for your help.

So the "Kalender" is listed if you open up with a browser? Don't try curl, just open it with your "default" browser
https://your.gromi.host/dav/calendars/user2@domain.tld/ where you can click on the fitting thing as seen here:

You can also use `https://..../dav/principals/user2@domain.tld` which can be helpful.

@crpb
Thank you for your answer.
I can access with a browser to the calendar. But when i logon with the 2nd user to my url I don't see the calendar:

on the left side logged in with the 2nd user, on the right side with my own user.

In webmail, however, it works without any problems:

Am I misunderstanding something?

sbrunner I can access with a browser to the calendar. But when i logon with the 2nd user to my url I don't see the calendar:

sbrunner on the left side logged in with the 2nd user, on the right side with my own user.

Uhm, you should just log in with your account that wants to access the "other account" and then when you are logged in browse to like .../principals/ and "add" the "other mailboxes e-mail-address" into the addressbar .../principals/other@mailbox.tld/
Don't switch accounts for that procedure..

Or this should make it clear? 🤔
https:///myaccount@domain.tld:secretpassword@grommunio.domain.tld/dav/principals/otheraccount@domain.tld/

curl --user "myaccount@domain.tld:secretpassword" https://grommunio.domain.tld/dav/principals/otheraccount@domain.tld/

crpb 🤔 sorry I'm lost.
I have done what you suggest, but I only end up on a page with user properties. I can't change any settings on this page:

What I am doing wrong?

If I see it correctly, the DAV functionality of Grommunio is a fork of sabre.io.
Sabre writes in its documentation that the Sharing plugin must be active for the sharing function. However, this is not displayed under the plugins. Could this be the cause?
