Hi, i've a SharePoint Server 2010 and im new to it. I've setup the Email-configuration how it's described here: http://technet.microsoft.com/en-us/library/cc263462.aspx#section5 Now the Problem is, that i can't send emails, cuz the of the following Error: "The e-mail message cannot be sent. Make sure the e-mail has a valid recipient." My Server is implemented in an AD, i set the Administrators account email as reciepient, smtp server ip: 10.xx.xx.xx . So what i have to do, that my SharePoint Server can send emails? I only want to send some, firstly ;) Thanks in advance.
