Lotus note – Split .nsf file

I personally don't have experience in with the Domino / AD integration, but I've long thought about it and hope to try implementing it this year. The things I do know is that IBM has a service built to synchronize Domino and AD user/group info in both directions, and that there is a company called PistolStar that appears to specialize in this area.

I would definitely start with the IBM integration service first and see where that gets you. In fact, I'm going to check it out today too.

The little I know of this issue is that this happens normally when someone with Outlook Client sends an email in "Outlook Rich Text" format. (Available to change from Tools|Options| Mail Format|Internet Format).

A non-Outlook client can't read this and just has an email with winmail.dat as an attachment.

We fixed this for people by making the default "Internet Format" on all the clients default to "HTML" if the original was Outlook Rich Text.

In your case one of 3 things is happening perhaps:

1. The company with Lotus Notes are sending their emails out in some form of "Outlook Rich Text" that is broken.

2. The Oulook clients aren't reading Outlook Rich Text format?

3. They are using the "Send as Email" option within Excel/Powerpoint which might generate an Outlook Rich Text email that lotus notes can't handle. Get them to create new mail in Lotus and attach the Excel file like a normal email.

This is not really an answer, but may be useful to narrow it down.
