I get the error ’Error: unable to save settings’ when updating settings in the old Webmail

This problem is typically caused by a corrupted user setting file. This problem can be resolved by deleting this file.

  1. The user should close Outlook, any other mail applications, and WebMail.
  2. On the mail server, go to the user's mail directory.
  3. Find the settings.usr file, and delete it.

The user should then be able to log in and not experience this error. If the error persists, contact Kerio Support.
