Narrative:

We apparently flew 3 flights with this aircraft where both the pilots and dispatch were unaware that the aircraft's CAT 3 status had expired. Aircraft was taken out of storage for this trip. Releases for all three segments were signed before the first flight; and there was no indication in the log history or the first maintenance release that CAT 3 had expired. On touchdown at ZZZ; the maintenance system 'auto-generated' a fault record; and then automatically issued a deferral. We were unaware that this had been entered into the electronic logbook; and must have missed it in the review of the maintenance release for the next (ZZZ-ZZZ1) segment. Dispatch discovered this after we pushed on the last segment (ZZZ1-ZZZ2); but was not able to contact us via ACARS; until after we were airborne. I called dispatcher after landing ZZZ2 to try to figure out what happened; and he looped maintenance control in for additional information. Weather was severe clear at all stations; and I am high minimums anyway; so safety was not compromised by not having CAT 3. The phase of flight/occurrence information above was where we were first informed of the issue by dispatch.
