Hi,
We are running Project Server 2013 on-premise and would like to share a project site-sub site / document library folders or individual files to external users. Contractors / Vendors/ Customers.
When I try to share a site / folder or document I enter in the external users email address ex. user@gmail.com
But when I click OK the following message appears.
"Sorry, you are not allowed to share this with external users."
How can I enable sharing externally. Can you please send me the exact steps?
Thanks
