There is a great piece of software called nlconverter. It’s a tool designed to convert Lotus Notes’
.nsf files to
mbox. It rely on win32’s COM/DDE API so it can only be used on Windows.
If you want to extract mails out of your
.nsf database, this might be the tool you’re looking for. Bonus point: it’s written in Python! ;)
Installing Nlconverter and Its Dependencies¶
Here is how I installed
nlconverter on a Windows 2000 (SP4) machine:
- Finally I had to download the latest
icalendararchive, then extract the
- Next step is to download nlconverter itself and extract it:
First thing you have to do is to create an export of your mails as a
.nsf database. Follow the previous link to get the instructions.
Now let’s convert this
nsf to a
mbox. nlconverter’s FAQ tells you to run the
gui.exe program to perform the conversion.
Unfortunately it didn’t work for me:
So I tried the alternative approach by using the command line.
Nlconverter Command Line¶
Again, most of the things I’m writing here are based on nlconverter’s FAQ:
- First, we have to download the
notes2mbox.pyscript from nlconverter’s mercurial repository, as this file is not distributed in the
winnlc-alpha-1.ziparchive I unzipped previously. Let’s put
Now we’ll modify the
notes2mbox.pyscript to set the password (via the
notesPasswdvariable) and location (
notesNsfPathvariable) of the
.nsffile. Here are the modifications I applied:
:::diff — notes2mbox.py.orig 2010-09-02 13:49:58.000000000 +0200 +++ notes2mbox.py 2010-09-02 13:51:24.000000000 +0200 @@ -14,8 +14,8 @@ import NlconverterLib
#Constantes -notesPasswd = “foobar” -notesNsfPath = “C:\archive.nsf” +notesPasswd = “XXXXXXXXXXXXX” +notesNsfPath = “C:\winnlc-alpha-1\kevin-notes-big-backup-part-1.nsf”
#Connection à Notes db = NlconverterLib.getNotesDb(notesNsfPath, notesPasswd)
Before running the script, we have to register a Notes DLL used by nlconverter:
:::bat regsvr32 “C:\Program Files\Notes\nlsxbe.dll”
And make the Python interpreter available system-wide:
Now we can run the
:::bat C:\winnlc-alpha-1>C:\Python26\python.exe notes2mbox.py
If you’re lucky, you’ll get a nice mbox at the end of the process.
But I was not and the
notes2mbox.py ended up with the following error:
Traceback (most recent call last): File "notes2mbox.py", line 21, in <module> db = NlconverterLib.getNotesDb(notesNsfPath, notesPasswd) File "C:\winnlc-alpha-1\NlconverterLib.py", line 43, in getNotesDb session = win32com.client.Dispatch(r'Lotus.NotesSession') File "C:\Python26\lib\site-packages\win32com\client\__init__.py", line 95, in Dispatch dispatch, userName = dynamic._GetGoodDispatchAndUserName(dispatch,userName,clsctx) File "C:\Python26\lib\site-packages\win32com\client\dynamic.py", line 104, in _GetGoodDispatchAndUserName return (_GetGoodDispatch(IDispatch, clsctx), userName) File "C:\Python26\lib\site-packages\win32com\client\dynamic.py", line 84, in _GetGoodDispatch IDispatch = pythoncom.CoCreateInstance(IDispatch, None, clsctx, pythoncom.IID_IDispatch) pywintypes.com_error: (-2147221231, 'ClassFactory ne peut pas fournir la classe demand\xe9e', None, None)
As you can see, I tried hard to make nlconverter working, without any success. But this should not stop you to try. In fact I suspect the Lotus Notes installed on my machine to be crippled or corrupted (can’t really tell). So you may be more lucky than me. In any case, feel free to report any success or failure in the comment section below!
