Solutions to “Cannot Send Emails From Outlook”
If you can not send emails from Outlook, try the below-mentioned solutions.
Solution 1: Send Again The Email
If you have been sending the email, but it was not being sent to the recipient, you should give it one more try. Generally, unsent emails exist in the “Outbox”. So, go to the “Outbox” and search for the email that you want to send. Once found, right-click on it and choose the “send” option.
Now for the confirmation, you may go to the “sent” folder and check whether that specific email resides there or not. If the email is present there in the “sent” folder, that clearly states that the email has been sent.
Solution 2: Check Internet Connection
To use Outlook, it is essential to have a proper internet connection. If you are connected to the internet but the status (located on the lower right side of the Outlook) states “working offline”, “disconnected”, “trying to connect” etc., this clearly means that you do not have a working internet connection.
To make the internet connection work again, you need to follow the below instructions.
- Reconnect to the internet
- Contact your ISP (Internet service provider) for non-availability of the internet
- Click on the Send/Receive button located under the Send/Receive tab at the top menu.
- Go to “https://fast.com/” and check whether the internet is working or not.
Solution 3: Recreate Email Profile
There is a need for this solution if your profile has gone corrupt. It is quite simple to create a new profile, and it is all up to you whether you want to delete or keep the old profile.
To do this, exit Outlook and follow the below steps.
- Step 1: Go to the Run command by pressing the win key + R. An image similar to the below will be visible.

- Step 11: After submitting all the values, click on the “Next” button and wait till the process gets complete.
This way, a new profile will be created. Relaunch the Outlook application and try sending the email once again, check if it resolves the issue or not.

Solution 5: Enable The TCP/IP Protocol
If the above solutions did not work, you may try enabling the TCP/IP Protocol. To achieve this, follow the below steps.
- Step 1: Press Win key + R, a dialogue box will open up
- Step 2: Type “ncpa.cpl” in the text box and choose the “OK” button.
- Step 3: A window similar to the below one will be opened. Right-click on the network adapter and select properties.
- Step 4: Under the networking tab, check the box in front of Internet Protocol Version 6 (TCP/IPv6). If it is checked already, leave it as it is.
- Step 5: Click on the “OK” button
After following this solution, try sending the email using Outlook and check whether the emails are being sent normally or the issue still persists. In the latter case, you may opt for the next solution.
Solution 6: Switch To Another Email Service Provider
Microsoft Outlook is the best email client as it has a bundle of features and is not confined to emails. If it is not functioning properly in your case, you may try switching to another email client. There is a huge list of email clients like Mozilla Thunderbird, Mailbird, Apple Mail, etc. You may prefer any of it according to your choice.
Solution 7: Examine Port Number
To send an email, outgoing mail server settings are required the most. But generally, ISP (Internet Service Provider) keeps port 25 blocked, which is needed for outgoing mail servers. So, you should contact the respective ISP and ask them to resolve the issue and also ask them to enable port 25 if not enabled.
Solution 8: Check Daily Quota of Sending Emails
If the daily limit of sending emails has reached, you will not be able to send emails anymore. So, in this case, you should wait for the day to end and should try sending the email the next day.
Solution 9: Avoid Attaching Large Files In Email
While attaching a file to the email, you should check the size of it. If the file is large, try splitting it into small sizes and later try sending the email. The maximum size limit for an email attachment lies at 10MB. If the attachment size exceeds it, you will not be able to send the email. So, have a sharp eye on attachment’s size.
Solution 10: Resolve Error Code, If Any
While operating Outlook if Outlook is not working, or you are facing any error code on the screen of the computer, you should first resolve that specific error code and later check whether Outlook is sending the email or not.
Solution 11: Cross-Check Recipient Email Address
Sometimes it is possible that the entered recipient email address is wrong or misspelled. In this case, you need to double-check the email address. Once you are sure about the recipient’s email address, go ahead and send the email.
