Sorry for the noise. It was a problem with one of the accounts.
Now it works as expected. Only one account needed and both cardav and caldav can connect. Tasks also work.
Need to restore calendar events from backup
My calendar events in VistaPrint webmail systematically disappeared. I can not get a resolution from them. Would DavDroid have a backup from Thursday 6/8 that I could restore to then sync everything from that? HELP! Please!!
There is no automatic backup in DAVdroid. You need to make backups on the server side on a regular basis if you protect yourself from data loss…
Thanks, I learned today that Vistaprint does not do any backup on calendar events. Basically, my events are now gone. I am dumbfounded that a company as big as Vistaprint would not be performing backups for its client.
I’m sorry to hear that… DAVdroid is (only) a sync adapter - it does not handle or make any backups, because it’s not the scope of a sync app…
