The error message, "Could not edit any of the map's layers. Check to see if a layer or table contains a unique index on a user managed column." appears when trying to edit a personal geodatabase feature class or table.
Edits cannot be made to a personal geodatabase feature class or table that has a unique index on a user-defined field. Also, edits cannot be made if the feature class resides in a dataset where another feature class has a unique index.
