After you complete each method, send yourself a test email message to make sure that you can send and receive messages without receiving an error message. If you continue to receive errors, try the next method.
Follow these steps:
-
Start an Internet browser. For example, start Microsoft Edge.
-
Type one of the following addresses in the address bar, and then press Enter.
-
http://www.microsoft.com

Method 2: Make sure your Outlook email account settings are correct
Check your Outlook settings. SeeHow to set up an Internet email account in Outlook 2013 or 2016 for more information.
Suspicious email messages may block your receiving error message in Outlook. If you have any suspicious email message, delete them by using one of the following methods:
-
Access your mailbox by using your ISP's web-based email program. Then, delete the email messages.
-
Contact your ISP and ask them to delete the email messages.
If your antivirus software includes an email-scanning feature, you may have to perform additional configuration tasks to use Outlook together with the antivirus software. For example, you may have to configure the Norton AntiVirus Office plug-in to work with Outlook.
For more information about how to use Outlook together with your antivirus software, go to one of the following websites, as appropriate for the antivirus software that you have installed:
Warning This workaround may make a computer or a network more vulnerable to attack by malicious users or by malicious software such as viruses. We do not recommend this workaround but are providing this information so that you can implement this workaround at your own discretion. Use this workaround at your own risk.
Configure your firewall software to enable the following file to access the Internet:
-
Outlook.exe
By default, port 25 is for outgoing access, and port 110 is for incoming access. If you are not sure about the ports, contact your ISP or system administrator.
More information for McAfee Personal Firewall and Norton Personal Firewall (Symantec)
Go to the McAfee website for instructions on how to configure McAfee Personal Firewall.
Or, you can remove and reinstall McAfee Personal Firewall. This reinstallation process will make sure that Outlook has Internet access, because the process re-creates the program signature file that is used by the firewall.
If you are running Norton Personal Firewall 2002, Norton Internet Security, or Norton SystemWorks software by Symantec, contact Symantec product support for upgrade or reconfiguration instructions to resolve your problem.

Note:This enables you to open the large email message, and remove, resize, and then re-add the attachments before you try to resend the email message again.
-
Delete the message: Right-click the message, and then select Delete.
Important:If you receive the message "Outlook is transmitting the message," close Outlook, and then wait for it to exit. You may have to use Task Manager in Windows to make sure that the Outlook.exe process is complete. Restart Outlook again, and then repeat this step.
