The option to set the for any SharePoint site access requests has moved around in the last few versions, so I thought I’d post this for those searching through old posts looking for one about SharePoint 2013.
This setting determines who will receive an email when a user requests access to a particular site—usually when the user tries to access the site and is denied. The tricky part is that the for this request is not related to the site owner permissions, it’s just a string.
To find the setting, navigate to:
Site (Gear icon on top-right) > Site permissions > Access Request Settings (in the ribbon)
First use the gear icon in the top-right corner to get to the Site Settings page. If you don’t see the Site Settings link, you probably don’t have sufficient rights to make this change.
Once there, click on Site permissions.
This will open the “Permissions: <site name>” page where you can access the Access Request option from the ribbon at the top of the screen. The option you’re changing is “Send all access requests to the following e-mail address.”
Simply the email address you’d like to use for access requests and you’re done.
