Reasons Why Outlook not sending emails

There are many reasons why Outlook is unable to send emails. Some of them are very common and simple to be fixed, while others can be a bit more complicated. Here are 10 most common reasons why Outlook not sending emails:

1. Junk Email Filters – If you have enabled junk email filters or blocked some senders, your email may not reach its destination.

2. Out of Office Reply – If you have replied to any email with an out of office reply message, then it will not send the message until you remove that reply.

3. Unsubscribe – If someone has subscribed to your newsletter but never received any message from you, then their email address might have been added as a contact in your block list or junk mail filter list. To get rid of this problem, you need to remove their contact details from those lists and then re-send the newsletter again. You can also try deleting all contacts from these lists before re-sending the newsletter again so that there is no chance of adding them again by mistake while managing other contacts too!

4. Autoconfiguration Settings – If autoconfiguration settings are enabled in Microsoft Outlook 2016/2013/2010/2007/2003/XP/2000 then it may cause problems while sending emails.

How to Fix Outlook not sending emails

Outlook is one of the leading email clients in the world, but it can occasionally misbehave. One of the most common issues with Outlook is that it doesn’t send emails, which can be extremely frustrating.

There are several reasons why this may happen. Here’s how to fix Outlook won’t send emails  and get back to business as usual:

Internet Connection

The first thing you need to check is your internet connection. If you have a problem with the network, it can cause issues with Outlook. So, try connecting to a different network and then send an email. If this works, then your problem probably lies with the network you were using before. In some cases, software updates may be causing problems. If you have recently updated your computer or device, try uninstalling it and reinstalling it again to see if that fixes the issue.

Check Your Firewall Settings

If you are using a firewall on your computer or device, then there might be something wrong with its settings. You will need to check these settings and make sure that they are correct so that your firewall does not block any emails from being sent out by Outlook.

Delete your Exchange account and recreate it

If you’re using Microsoft Exchange as your email server, there may be an issue with DNS records or certificates. Try deleting the account from within Outlook and recreating it from scratch. If that doesn’t work, you might need to contact your IT department for help.

Uninstall and reinstall Outlook

Outlook stores a lot of information related to your email accounts on your local machine, so if something goes wrong with your computer or operating system, it could cause problems with sending emails. Uninstalling and reinstalling Outlook should fix this issue almost every time it occurs.

Run a virus scan

If nothing else works, run a full virus scan on your computer using Windows Defender or another antivirus program — anything that might have infected your computer and stopped Outlook working properly should be removed during this process.
