Crucible problem sending email 530 5.7.1 Client was not authenticated

[Piotr Swiecicki]

Seems like the problems with your configuration, please ensure you have configured SSL/TLS (as required by your Exchange server) and username/password correctly, see https://confluence.atlassian.com/fisheye/configuring-smtp-298976823.html . You may also need to enable basic authentication on the Exchange server.

If this still doesn't help take a look at the answer to similar question answered regarding JIRA configuration: Send email problem, Client was not authenticated.  It seems Exchange needs to be configured correctly to allow Basic Auth.

Hope that helps, 

Piotr
