La sincronizzazione delle cartelle è fallita a causa del seguente errore: An access token must be provided to use GOAuthRequestFactory () "

Buongiorno, da 5 giorni non riesco a sincronizzare le caselle Gmail: " 14:37:52 MailClient.Storage.Application.OperationException: La sincronizzazione dell’elenco delle cartelle è fallita a causa del seguente errore: An access token must be provided to use GOAuthRequestFactory () "

Hello Felice,

Unfortunately we provide support only in English. 

If I understand correctly, you have issues with Gmail OAuth. It might be one of the cases when after an update eM Client has difficulties while authentication to Gmail after an update. Please try deleting this account and then add it again to see if it helps your issue.

Regards,
Russel
