If the mailbox structure has been successfully created already and your 
problem really is just the mbtype listed in the mailboxes database, I 
think you should be able to rectify this by sending an ACTIVATE command 
to the mupdate server for the affected mailboxes.

http://tools.ietf.org/html/draft-siemborski-mupdate-04#section-9.1

For example, using mupdatetest:

$ mupdatetest -m GSSAPI your.mupdate.server.com.
S: * AUTH "GSSAPI"
S: * COMPRESS "DEFLATE"
S: * PARTIAL-UPDATE
S: * OK MUPDATE "your.mupdate.server.com" "Cyrus Murder" "v2.3.16" 
"(master)"
C: A01 AUTHENTICATE "GSSAPI" {752+}
...snipped...
S: A01 OK "Authenticated"
Authenticated.
1 ACTIVATE "user.testuser" "your.cyrus.backend.com!u1" "testuser lrswipcda"
1 OK "done"
2 logout
2 OK "bye-bye"

Thanks,

Dave
