+/**
+ *  Most recent used name and address store
+ *
+ *  Reads and writes most recent used email addresses to central
+ *  repository. Central repository stores key - value -pairs. In this
+ *  case, first 16 bits of a key is used to identify mailbox and last 16
+ *  bits makes key unique for name and address information. Example:
+ *
+ *  Key         Value
+ *  0000 0000   <mailboxId1>                     : integer
+ *  0000 0001   <1. name of mailboxid1>          : descriptor
+ *  0000 0002   <1. email addr of mailboxid1>    : descriptor
+ *  0000 0003   <2. name of mailboxid1>          : descriptor
+ *  0000 0004   <2. email addr of mailbodid1>    : descriptor
+ *  .... ....
+ *  .... ....
+ *  0001 0000   <mailboxId2>                     : integer
+ *  0001 0001   <1. email addr of mailboxid2>    : descriptor
+ *  0001 0002   <1. email addr of mailboxid2>    : descriptor
+ *  .... ....
+ *  .... ....
+ *  FFFF 0000   <mailboxIdFFFF+1>                : integer
+ *  FFFF 0001   <1. email addr of mailboxIdNNNN> : descriptor
+ *  FFFF 0002   <1. email addr of mailboxIdNNNN> : descriptor
