Do you have a Outlook object model matching your Outlook version? Maybe you could generate one with 'makepy' and check if using this makes any difference.

Ok. I’ll take that as good news.

I have been able to reproduce this exception through the IDE debugger by just running msgstore.py by itself. It appears that the call to MAPIMsgStore constructor (in function test) is returning successfully, and it looks like valid data. The exception happens on the next line, in the store.GetFolderGenerator function. I can’t seem to generate a valid folder (store_id and entry_id tuple). The store_id and entry_id are strings. Are they supposed to be encoded as something else in Python3 in order to work with pywin32 and mapi? Byte strings don’t seem to work. The call originally had mapi.BinFromHex in NormalizeId, but that doesn’t seem to work with Python strings, or byte strings. Because NormalizeId isn’t generating something useful, the call to _OpenEntry a few lines later, which calls _GetMessageStore, which calls session.OpenMsgStore, fails.

I’m not familiar enough with this Outlook Add Ins or the pywin32 library to guess a next step. Could this be a permissions issue? I’d like to think not, since the 32 bit version of Outlook works with Spambayes, and, with the 64 bit version of Outlook, the MAPILogonEx call seems to work.

That exception looks more like we can't access the message store rather than a 64/32 bit mismatch. It may be that you need to enable MAPI access or something similar but I'm afraid I've never used newer versions of office. Googling for MAPI_E_INVALID_ENTRYID with Office 365 is probably the best path forward.

    One thing I’m suspicious of (and I hope I’m wrong) is if the
    problem is the win32 related modules. I’m doing this on a 64bit
    machine, trying to get this to work with the 64bit install of
    Outlook (Office 365). Could that be my problem? Should I be
    looking for win64 related modules? (Do any exist? I didn’t see any
    on pypi.org? Or is that also a wrong direction?) At this point, I
    don’t know enough about COM or 32bit vs 64bit to know what to try
    next.

    Thanks in advance,
