I just installed the product for the first time and I'm going through the initial configuration. I'm attempting to setup the Mail Settings but it appears that the page isn't saving the SMTP password. I enter it in and save it but when I send a test email, I get the following error. 

530 5.7.57 SMTP; Client was not authenticated to send anonymous mail during MAIL FROM [DM5PR1301CA0011.namprd13.prod.outlook.com] 

When I look at advanced settings, the password field is blank even after attempting to save multiple times. I've tried simplifying the password to text only just in case one of the special characters was illegal but that didn't make any difference. 

Can someone please help me figure this out?

Thanks
