Sounds like MAPI got affected by some software installation. Maybe reinstalling Outlook could fix it?

>About a year ago I started using the MAPIMAIL class in one of my projects which was installed on 8 computers. Testing was successful with both OutLook and OutLook Express.
>I was advised a couple of days ago that on some of the computers, the E-mails are no longer being sent. According to the client, the problem seems to be related to adding other software.
>I was able to re-test on one computer running W95 & OutLook 2000. The Outlook 'Select a Profile' window pops-up as it did before but the E-mail can not be found in the OutBox or Sent folders.
>All assistance is appreciated.
>TIA.
