I have a problem when send invitation to a teamsite to user from SharePoint2013 Enterprise. In the Outgoing E-Mail settings I have set a from address [email protected]. In the descpritopn of Mail Settings says “ Specify the SMTP mail server to use for Microsoft SharePoint Foundation e-mail-based notifications for alerts, invitations, and administrator notifications. Personalize the From address and Reply-to address” so the From address might be the one used.
When I invite a user to a site/SharePoint Group I get a mail from myself (my mail address instead of the apps.teamsite…address) saying I invited the user and a mail is also sent to the invited user. Now starts our problem. We have users in our domain from another mail domain with another mail suffix, @yyy.com. Our external mail router is not accepting mail not coming from our internal mail domain. In this case the user inviting a user has the mail address [email protected] and the user inviting gets an error message from the mail router system saying the mail could not be sent. The inviting user gets worried that the access is not working correct. Why isn’t the From Address setting used as the From address? Can this be fixed so the mail comes from the [email protected]?
