Stop Outlook from Sending Multiple Emails

From last 2 to 3 days, whenever I am sending emails through Microsoft Outlook 2016, my recipients are getting multiple copies to same mail. On the first day only one recipient complained me for the same but, with passing of each day counting of the same complaint got increased. I don’t know why it is happening because I am sending messages only for once. Please can anyone assist me regarding the same? Any suggestion regarding solution of this problem will be highly appreciable. Thanks in advance!

Are you also one of the Microsoft clients, who is facing same sort of problem? Don’t panic, here we are with solution of troubleshooting your issue! The blog is going to describe a foolproof approach through which customers can stop Outlook from sending multiple emails to their recipients.

First Look At the Procedure of Email Transmission

Microsoft Outlook stores all the email messages in an organized manner and enables individuals to view them in offline mode. It fetches typical emails from the server and stores them on the local computer to prevent the use of Internet all the time. The idea of dial-up internet users to work with desktop-based email client is brilliant because emails get automatically exchanged when internet connection is established.

However, the process gets interrupted due to some unknown threat, causing different sort of problems while mailing. One of the most common problems is ‘Outlook is Sending several copies of an Email’. To understand the solution for stopping Outlook from sending multiple emails, first you have to be known from actual email transmission process. So, go through the following statements :

“The email service provider stores electronic mails on a server. When an individual sends you a message, it does not get transmitted directly to your PC. This respective mail first gets stored on the server and when your Outlook detects active internet connection, it fetches the mail from server”

Why Recipients Receive Multiple Emails?

According to the observation of Outlook experts, there exists three major reasons due to which ‘Stop Outlook from Sending Multiple Emails’ trouble occurs. Description of these causes is given below.

Short Time for Send/Receive Connection – Some users set the time duration of Send / Receive connection for very short time, say less than 4 minutes. This is a major cause behind occurrence of the problem because when email is uploaded on the server, it might happen that next cycle of Send / Receiver process starts, before completing the previous one.

Presence of An Anti-virus Software – When Outlook app gets consolidated with anti-virus, it affects the ongoing work of email client. Presence of the misconfiguration settings in between both these apps lead to this problem.

Presence of Slow Mail Host Connection – The working of IMAP and POP accounts takes place on the basis of server timeout. When the internet connection is slow, it could match the specified timeout and hence, submit same mail again on next attempt.

Measures to Stop Outlook from Sending Multiple Emails

Readers need to attempt all the defined procedures one-by-one. The one that fixes the problem at instant is the solution over your problem, and then you don’t have to proceed further.
