I am not experienced in VB but have received help in the past. One part of the code for sending emails from Access through Outlook that I received in the past is
strEmail = """" & .Column(1, varItem) & ""
where the information that is picked up from Column 1 is either simply '***@gmail.com' or '***@Gmail.com; ***@talktalk.net'. This has worked in the past but today where there is only one email address in this field everything works OK but it throws up a problem then there are 2 - the message reads 'Run-time error 2205. Unknown message recipient. the message was not sent'. If I copy the 2 email addresses from the field and paste them into Outlook there is no problem sending an email to both. Has something happened in some download from MS that is causing this problem? Does the wording of the strEmail cause the problem? If so, can it be modified simply to handle either 1 or 2 email addresses?
