Extension Manager hooks problem

Dear Colleagues,

We are writing extension manager to Notes, the extension manager traps the following hooks:

EM_MAILSENDNOTE,

EM_NSFNOTEEXTRACTFILE,

EM_NSFDBOPENEXTENDED,

EM_GETPASSWORD,

EM_NSFNOTEUPDATE,

EM_NSFNOTEUPDATEXTENDED,

EM_NSFNOTEDELETE,

EM_SCHFREETIMESEARCH,

EM_SCHRETRIEVE,

EM_SCHSRVRETRIEVE,

In particular we are interested in trapping any attempt of the user to send a note and checking for schedules of a list of invitees of a meeting as well as some other actions.

We are testing our code with Notes 6.02CF2 English version and our Domino Server is 6.02CF2 Japanese.

The extension successfully trap almost all of the above hooks, the problem is we never get the EM_SCHRETRIEVE or any of the schedule messages (EM_SCHFREETIMESEARCH, EM_SCHSRVRETRIEVE) instead the action of “Checking All Schedule…” mysteriously fire the EM_MAILSENDNOTE message.

Any ideas of why the Japanese Inbox never fires the EM_SCHRETRIEVE message, could it be problem with mail file design?

Thanks,

Ron
