Peoples App / Sync with T-Online

Hello everybody, can anyone give me an advice how to sync (two way!) my contacts with my email-account (T-Online)? → Xperia XA2, SFOS 5.0

you need to add a CalDAV and CardDAV Account in settings with your credentials and server settings and choose “Synchronisation” Two Ways, choose an update interval and select the checkbox contacts

Thank you very much! Works fine with calendar, but not with contacts (same settings)???

when you open “extended settings” in the pulley menu of the account there is “path to adress book” maybe you have to enter something there. For my posteo account it does work without explicit path, but maybe T-Online has a different setting

You could try to add “/.well-known/carddav” in the extended setting for CardDAV, that seems to be their path

Interestingly synching contacts works now, but only oneway (T-Online → XA2); and the synched contacts can neither be updated nor deletd.
