It was based in a chemist on Ely High Street but when the lease was not renewed a new premises had to be found.
As a temporary fix, the post office has been relocated to a new temporary home in a car park on the edge of the main shopping area.
Post Office managers admit they do not yet know where, or when, they will find a business willing to take it on.
It comes as many branches seek to save money by sharing facilities with other shops.
