Thanks for your report,

The failing migration Version3001Date20230307113544 is three years old.

Did you delete some rows from oc_migrations (that would explain why the migration runs again)?

Thanks for the quick response. No i i did't delete any rows. Do i have install nextcloud again? Do you have a solution for the problem. I didn't use mail till now. Greetz, Guy Op di 31 mrt 2026, 21:52 schreef Daniel ***@***.***>:

Should be enough to reset the mail app: https://github.com/nextcloud/mail/blob/main/doc/developer.md#resetting-the-app.

This will remove all existing data for the mail app.
