When sending the email is
a. not being copied to the sent box and remains in the Outbox
b. this means the email is being sent several times until I delete it or copy it to another directory
c. I have checked the settings and emails are set to 'copy to sent box' when they have been sent
d. I have checked the time settings and these are correct
e. Outlook reports an error on sending but does not give further details of the nature of the error
The sent box does have 25000 items in it so I transferred them to another directory but Outlook won't let me delete the emails which have remained in the sent box
Can anyone advise on how the emails can only be sent once and transferred from the outbox to sent box? Also how to delete the emails that are in the sent box?
Thanks
