I went to add a new email user but this message came up.
You don’t appear to have enough enabled licenses to create a mailbox. If you have recently ordered a license then please wait a little while for this to be enabled and then try again.If you know that you have not purchased enough extra licenses then please buy a new license, or delete an existing mailbox, to re-use its license.
How do I buy a new license?
Cheers
Yes I had this - it's really not at all obvious, when you get that message and try and click on buy new licence it doesnt work.
I had to call and get help, very helpful chap called Ian from BT sent me this which worked a treat. have to say though - not at all obvious!
