I'm using access 97 and outlook express to send emails using the docmd.sendobject method. I have this on about 25 computers at my place of work and about five of them are not working. The five computers when I try to send and email tell me they can not send message due to the preceding error. There is no preceding error before the message comes up. All 25 of the computers are using Access 97, outlook express, windows xp with service pack 3. According to microsoft the message should come up due to a security update in Outlook. Outlook is not installed on any of the computers. Whats causing this? Thanks in advance.
