I put together some VBA code for Outlook 2007 which has been working predominantly fine.
Its basically designed to check incoming messages and store the subject, body etc into a database and the attachment into a folder. In general, it works fine, but out of 100 messages or so, it drops the odd email.
I previously had a problem where some emails were not being processed and stored in the database, but then discovered there was an issue with illegal characters, which i have solved now, so that cant be it. I’ve compared the emails being dropped to the one’s that arent, in terms of message header, content to and from fields and i cant see any difference between the two emails at all, so am completely perplexed as to why they’re being dropped. When i copy the content of the email and forward it back to the system again, the VBA code processes it fine.
I am pasting the code below (the code links to some modules which are used for checking illegal characters or concatenating strings)

You should add some logging to help track down the problem.
I haven’t used this personally, but maybe give it a go: Log4VBA
Also, you should add error handling:
