Is it possible to integrate the CalDAV calendar into the Android Outlook app? Usually, CalDAV calendars don’t appear in the Android Outlook app, so I search for a way to integrate CalDAV into Outlook. I know there is a software called [Outlook CalDav Synchronizer](https://caldavsynchronizer.org/) but it's only for desktop (Windows). There is another app called [DAVx5](https://www.davx5.com/) to synchronize CalDAV, but it's a paid app and I don't want to waste it. Does someone have the experience?

I am trying to migrate from a broken calendar account (no remote sync access, but the phone has all the data cached locally) to a self-hosted CalDAV calendar (connected to by DAVx ). Both calendar accounts are in DAVx, and both are visible in calendar apps. Question: How do you export an existing calendar to another calendar on the device? I have both the "Google Calendar" app and the default Calendar app that comes with LineageOS, but neither appear to support export/import---or at least I cannot find the option. There are _lots_ of calendar events, so we need to do it in bulk. With contacts, it is simple: you can export a .vcs to a file and import the .vcs to another contact account with the "Contacts" app. But with I can't figure out how to do the same thing with a calendar account. Ideas?

When I create an event in Nextcloud Calendar (or through Thunderbird Lightning) while forcing the status as **confirmed**, it is not propagated correctly to Android through CalDAV. I am sure that the event has a good status since when I record it, it looks like that:

When I sync it on my phone running Android 10 (Fairphone 2 running [/e/ OS](https://e.foundation) 1.6, I guess it is done through [DAVx5](https://www.davx5.com) which is included in /e/), the status is not there anymore and all calendar apps ask me if I will participate in the event. The event seen in Android does not have the status anymore (where my email is replaced by MYMAIL@MYDOMAIN):

Any idea what I did in the wrong way or where (Nextcloud/Android/e/DAVX5) to find or report the bug if it is one? By the way, everything is working fine when done the other way (event created under Android and synced to Nextcloud server): status is **confirmed** in the created event.

Android has a bug report Add support for external calendars via iCal / CalDav that prevents you from using a standard CalDAV application. CalDAV-Sync corrects that bug: > CalDAV-Sync is a CalDAV client for Android to synchronize events. Due to its implementation as sync adapter it integrates seamlessly with the native calendar app and widgets.(Also check out CardDAV-Sync) > > Important note for Jelly Bean users: To prevent the removal of your accounts on reboot install this app: > https://play.google.com/store/apps/details?id=org.dmfs.jb.workaround.caldavsync > > This app will create new calendars on your device (one for each calendar on your server account) **How exactly does it solve it?** Is it an alternative synchronisation? Or does it correct the bug?

My calendar is a conglomerate of different event sources (personal, work, etc). I bring them together using the [CalDav](https://en.wikipedia.org/wiki/CalDAV) standard - on Android using the [DAVdroid](https://www.davdroid.com/) application. There is however an event source that does not support CalDav natively: Outlook. On PCs, this is easily manageable with a programme like [DavMail](http://davmail.sourceforge.net/) , that serves as a gateway to Outlook, providing a CalDav interface. I would like to do something similar on Android in order to integrate CalDav event sources with Outlook in the Calendar application. Which method(s) could achieve this goal?

On my phone, I have a calendar synchronized via CalDAV-Sync on a server of mine. On the desktop, I edit them with Thunderbird, and since Thunderbird can associate tasks to a calendar, I was wondering, if is there a way to see those tasks on Android too, since I can already see (and edit) the calendar itself?

I have a Xiaomi Redmi 4X Device with stock Android (no custom OS installation or modifications). I run a Radicale CalDAV server at home and have installed the DAVDroid app (via F-Droid). Inside DAVDroid app, I have set up the connection to my CalDAV server and DAVDroid shows up the calendar, so the connection to the server is fine. Problems occur when I want to use the calendar with the Calendar app on the phone. In the calendar app, I want (i.e. I have) to choose the CalDAV calendar as a "calendar account", but the DAVDroid account is not showing up in the list of available calendar accounts although it definitely exists. (I did some other tests using the aCalDAV app from the Google Play Store and the aCalDAV account shows up and is working). Is there maybe a problem that DAVDroid has because it does not have all the needed permissions? I have no idea how to resolve the issue, so any hints are welcome.
