Use SSL for Outgoing Connection / Incoming Connection Radio Buttons Greyed Out for CRM Server Side Sync POP3-SMTP Profile

If you need to create a Server Side Sync profile for your POP3 and/or SMTP servers without using SSL for your on-premise CRM 2013, 2015, or 2016 environments you may notice that you are unable to change the option to not use SSL. The radio buttons are simply greyed out and stuck set to “Yes”. This can be problematic if you want to run over basic HTTP.

Luckily, these buttons can be enabled via the following PowerShell commands run on the CRM server:

Add-PSSnapin Microsoft.Crm.Powershell
$setting=Get-CrmSetting ServerSideSyncEmailSettings
$setting.AllowNonSSLEmail=$True
Set-CrmSetting $setting
Get-CrmSetting -SettingType ServerSideSyncEmailsettings
Exit

After the commands are complete, refresh your browser and the buttons should now be active.
