If you have configured Exchange 2013 in hybrid mode then you have probably noticed the appearance of this link. It’s the Office 365 Mailbox creation link.
However, if you have implemented RBAC this link may not show when you’d expect it to.
I ran into this recently when upgrading an Exchange 2010 hybrid environment to 2013. Previously the client had implemented RBAC where members of the helpdesk team were added to the Recipient Management group. In 2010 this allowed the helpdesk team to create and manage mail recipients; both on-premise and in the cloud. However, when this group attempted to use the 2013 management tools the Office 365 Mailbox link was absent.
After some digging–plus some trial and error–we quickly found an oddity. The short answer–it’s all based around one missing role entry. To see that link you need access to the Get-RemoteDomain command. Members of Recipient Management do not have this.[Read more…] about RBAC hides the Office 365 Mailbox creation link
