When I try to enable a user account I get an error: “The server is unwilling to process the request.”

This error most commonly occurs when you are attempting to do something that the server’s security policy forbids.

For example, check that you have assigned the user a password in a previous message that complies with any password complexity and history policies you may have in your domain.
