Encryption pass validation failing with error ID 34507, 100025.
Probable cause of this issue could be 1. You are trying to change the encryption pass phrase and the online backup local state has been lost. 2. You are trying to recover files from alternate server for which you forgot the pass phrase.
Check the pass phrase file stored by you while setting the pass-phrase for that server. We recommend storing the pass phrases in standard secured environment. In case you as forgot the pass phrase and also lost the pass phrase file, your data will not be recoverable. This is because Microsoft Online Backup service does not store the encryption key details for security reasons and data can not be decrypted without user providing the pass phrase. You can however reclaim the space by unregistering a server, all the data related to this server will be deleted, and you re-register this server again and start using the online backup feature.
