“Some of my
clients complain that they receive multiple copies of emails that I send to
them. This creates duplicate emails in their Outlook inbox which is quite
disturbing for me. However, it does not happen every time I send a mail with
attachments but generally 8-9 copies of a message are sent to them from my end.
How
can I solve the problem of Outlook sending emails more than once and stay
assured that my client’s inbox do not get piled up with duplicate emails?”
If you are one amongst those who are troubled that
Outlook sends multiple copies of same email, then here we are going to talk
about some of the solutions that might help you out! Basically, this problem is
connected to virus integration with Outlook or when send/receive cycle is
disturbed due to short Server timeouts.
Anti-Virus
For Outlook: Yes or No?
Over the time, it has been noticed that anti-virus
programs have negative effect on Outlook performance rather than doing anything
good to it. Meanwhile, it is important to know that MS Outlook has built-in
filters to detect spam or virus threats with emails and so there is no need as
such to integrate virus scanners with the application. It would end up with
more problems indeed. So, it is better to uninstall anti-virus integration
with Outlook.
Short
Send/Receive Interval for Emails?
When your recipients
complain about Outlook email received multiple times, the other reason could be
short time period set to send and receive messages (generally less than 5
minutes). When a mail is sent, there is a time-interval taken by the email to
get uploaded on mail Server and possibility is that a new send/receive cycle gets
started before the previous one ends. This will generate a backlog for the
send/receive cycle which has to be successfully processed.
In some of the bad scenarios, the message get stuck in
outbox and gets continuously resubmitted for sending. This creates duplicate
emails in Outlook inbox of the receiver when the sending is completed.
By default, the send/receive cycle is processed every
30 minutes but this value can be changed. Set the value for “Schedule an
automatic send/receive every” at-least 5 minutes. If there are multiple
accounts in Outlook, then it should not be lower than 10 minutes. To change
send/receive interval:
Outlook
2007:
In “Tools” menu, move down to “Options”.
Click on “Mail Setup” tab and “Send/Receive”
Outlook
2010/Outlook 2013
In the “File” menu, move to “Options”
Click on “Advanced” and the “Send/Receive
Outlook
Server Timeout Setting
When Outlook is configured with POP3 or IMAP, they work
according to Server timeout. The main role of Server timeout is to instruct Outlook
when a connection should be considered “lost” when there is no response from
the Server. By default, this time is 1 minute and it should be at-least 5
minutes. Such scenarios also results in Outlook message stuck in outbox issues
when attachment or overall message size is large.
