Just upgrade to Max 8. On one PC the user cannot send email. The email sits in Outlook's Outbox with the error message:
This message could not be sent because one of the recipients was rejected by the server. Server response: '501 <Joe Bloggs <firstname.lastname@example.org>>: "@" or "." expected after "Joe"'. (Account: 'Me', SMTP Server: 'smtp.mydomain.com', Error Number: 0x800ccc79).
Have changed certain names to protect the innocent.
The user has to edit the email in the Outbox, modify the recipient details to remove the contact name & only have the email address listed. Can send email to the same contacts on other PCs ok. OS is Win2k & using Outlook 2000
