    Error "Failed to send notification. Cannot retrieve the Information for application credential key"

    Summary
    Workflows might fail with the following error: "Failed to send notification. Cannot retrieve the Information for application credential key." Additionally, email notifications are not sent and the People Picker control fails to resolve users.

    Solution

    Re-enter the username and password values for the People Picker using PowerShell:

    PS C:\> STSADM.exe -o setproperty -pn peoplepicker-searchadforests -pv "forest:*YOURDOMAIN*,*USERPICKACCOUNT*,*USERPICKPASSWORD*" -url http://*YOURWEBAPPLICATION*

    If you continue to get the same error run the below commands:

    PS C:\> stsadm -o setapppassword -password *USERPICKPASSWORD*

    Operation completed successfully. (expected output)

    PS C:\> STSADM.exe -o setproperty -pn peoplepicker-searchadforests -pv "forest:*YOURDOMAIN*,*USERPICKACCOUNT*,*USERPIKPASSWORD*" -url http://*YOURWEBAPPLICATION*

    Operation completed successfully. (expected output)
