Hi. I am trying to add Site Mailbox to my site, but when i try to enable the feature from Manage Site Features i get this error message:
Farm
The feature being activated is a Site scoped feature which has a dependency on a Farm scoped feature which has not been activated. Please activate the following feature before trying again: Site Mailboxes 3a11d8ef-641e-4c79-b4d9-be3b17f9607c
Any ideas as to how i can fix this? (I have exchange server setup and incoming/outgoing emails (to documents etc is working just fine..)
