Another issue is:

-  Frontend with  2.3.16
-  Backend with 2.4
-  And a account in this backend accesing a shared mailbox
in another backemd with cyrus 2.3.16


The shared  imap mailbox  appears with  a \Noselect flag.
And normally this means the folder can contain child folders, but not messages.


With:

-  Frontend with  2.4
-  Backend with 2.4
-  And a account in this backend accesing a shared mailbox
in another backemd with cyrus 2.3.16

no problem.


My sugestion is  upgrade  MUPDATE first , Frontends after  and
Backends at the end.
