Problem
You’re attempting to configure the email server settings in Citrix Command Center but notice that you receive the following error when you save the configuration:
Error
Connection to mail server failed, provide accurate mail settings
Solution
While there could be several reasons why this error is thrown, one of the more common causes I’ve seen at clients is that they’ve configured their anonymous receive connector correct to receive mail but had forgotten to uncheck the Require that all senders are authenticated option:
… for the Microsoft Exchange distribution group they’ve specified in the To Address:
If Require that all senders are authenticated option for the distribution group is required to be enabled then a receive connector that requires authentication should be created and user credentials should be filled in for the Configure Email Server Settings.
