Hi all I'm a support engineer at Menzies Aviation, and I have a query for all you experts out there! Recently we have been deprovisioning accounts in Active Directory that haven't been used for X amount of time. One of these accounts was deprovisioned and permanently deleted recently. We immediately got a call from a user complaining emails had stopped coming through...it turns out the account was just being used as an email address while the computer itself was using a different I.D. So, to cut a long story short, we created the account again, set the exchange account up and so on. Since we have done that, if the user has an Excel sheet open and does the following: clicks the menu clicks send clicks email Excel actually opens up the email without any problems and the file is attached, but when it's sent...it just doesn't get received by anybody. There's also no mail delivery failure and so on. This doesn't apply if: I send an email to the address from my outlook with an attachment The user sends an email from the PC/email account in question manually to itself So it seems to be a strange Excel only issue...hence me posting within this section. I hope the above makes sense, if not...fire any questions my way and I'll do my best to answer them. Regards John
