Problems with Recurring events syncing to fastmail server

[Daniel G]

I created a Recurring event using CalenGoo on Android. Then several days later, I deleted a single event using CalenGoo on Android. I get the following error in the Erroneous events section of Changes to upload: "Error: Read only calendar? Error 403".

 I am able to create and delete single events without any problems.

The calendar server is a CalDAV server for fastmail.com.

Thanks

Dan

Hi Dan!

It looks as if the event was uploaded correctly:

Feb 26, 2026 11:33:18 AM: CalDAV save event 2
Feb 26, 2026 11:33:20 AM: Sync finished successfully at Thu Feb 26 11:33:20 MST 2026

Maybe we can see more in the CalDAV log. Please open "Settings > Information > CalDAV log" and turn "Active: CalDAV log" on. Then try to delete a single event of that recurring event again. Wait for the sync to finish and then open "Settings > Information > CalDAV log" again and check if you can see the upload and maybe an error there.

Thank you very much!

Kind regards

Dominique

I turned on "Settings > Information > CalDAV log". It shows Enabled: CalDAV Log with a check mark next to it.

Then I deleted a single event and looked at the CalDAV log and it still said "No events were logged.". 

I then did a manual sync and the log still said "No events were logged."

I thought this was weird, so I deleted a non-recurring item to test if it was logging. I received this info in CalDAV Log. 

Note that I removed my email address.
