Report Onedrive sync error 507978 in Android Posted February 22, 2020 · Edited February 22, 2020 by EricK Update on troubleshooting tried I'm having a similar issue in Empass for Android. Empass says my storage limit has been reached for OneDrive and it fails to reauthenticate. I followed the instructions to disconnect and renamed the vault in OneDrive to 'oldvault' but when trying to resync Empass to OneDrive it fails giving a message in Enpass "The sync with OneDrive was cancelled by the user." But I did not cancel it. Then trying again Enpass is stuck back on the error message saying my OneDrive Storage Limit has been reached. I confirmed that I have storage available in OneDrive by copying a file successfully into OneDrive. I pay for 1TB in my OneDrive and space is not a problem. I noticed Enpass updated recently... is there a bug in the app?!? Please Help - I need my password manager to be syncing!
