I have done a list of all the mailboxes--the first one is all blank--the second one is "0"/ext 10---then 14 mailboxes--then 411 then the 900 series boxes (982-999)

I did a "power shut down" in Admin yesterday and shut system down, reseated the DK, then powered back up. Everything came up normal except for the MBs that I can't access. Both visually (in laptop Admin) and aurally(phone admin) the system says that the boxes are there but I can not get into them & the AA gives a "that is invalid entry" when trying to access station from the AA.

Will a plug & play help this?? We have to do something here, we're still on square one.
Thanks
