Updated to the new Norton 360 this morning. I am now unable to access any email accounts in Microsoft Office 2021 Outlook. Disabled Norton 360 - still could not access any emails as unable to access server. Used Norton uninstall and reinstall. When uninstalled, access to all email accounts restored. As soon as I reinstalled Norton 360, unable to access Microsoft server again. Checked firewall/Program Control settings. All Microsoft Office and Outlook apps set to allowed. Norton support only suggested running the Norton Removal and reinstall again. They have now escalated the query. Meanwhile, has anyone come across this issue and found a solution?
I have the same problem using MS Outlook 365 on Windows 10, but only intermittently. I do not understand why I can receive and send sometimes, but other times, not.
I am using Thunderbird and same thing happened to me. At first I thought it the problem with Thunderbird. I uninstalled and reinstalled the mail client and it worked for some time. At the moment it only works when email protection is disabled. I am using windows 11 professional.
My Outlook 2019 stopped receiving (SMTP) and sending (POP3) last evening but emails were still accessible via webmail. After much back and forth with my email provider, I had to get creative. I found out the same as you. Disabling Norton didn’t change the error. However, disabling anti-spam fixed the problem. Right now, I have email protection turned on but scan inbound and outbound emails turned off. Maybe it will check the attachments, maybe not. The new Norton interface is horrible. Give me back the old Norton 360 any day. Oh, and Symantec is welcome to fix their obvious POP/SMTP problem.
This problem has just appeared with Thunderbird on my computer.
Have they fixed it yet?
Hi Connie. THANK YOU for your feedback - it seems like that is exactly my issue! But I am nowhere near as clever as you!! Could you please tell me (“Dumbo” here) when you disabled anti-spam, was that in Norton? I have looked on the Norton 360 Settings but can’t find Anti-Spam, to turn off. And also “email protection turned on” - is that in Norton also?
Thanks again for your input…
Maybe you’ve solved this by now. I’m sorry that I didn’t notice your follow-up question. This worked for me in Outlook 2019. As mentioned previously, I stopped receiving ALL emails.
Do make sure there’s no remaining anti-spam add-in in Outlook for Norton. That disappeared in favor of managing everything in Norton but still, check that it’s gone or disabled.
In Norton, go to “Settings” and “Antivirus.” There is an “Email Protection” tab. Leave “Email Protection” on but turn off both scans, “Scan inbound emails” and “Scan outbound emails.” It appears that the attachments are still scanned in Outlook but who knows?
I hope this helps. I haven’t had the patience to turn them back on and test to see if Norton fixed the problem.
Typical Gen Digital.
- Fix one thing.
- Break another thing.
- Don’t test the software.
- Release to unsuspecting customers and let them figure it out.
Fixed:
Firewall notifications now work as intended.
Broken:
Email protection (SMTP/POP) with SSL/TLS
You have to completely disable email protection in order for Outlook to be able to receive/send emails, otherwise it returns encryption not supported.
This is a major security issue.
Had a similar issue, had to add a Norton cert as trusted in my mail app.Search for “Troubleshooting email client warnings about invalid server certificates” within Norton support.

I was once in a similar situation. I turned on the email protection for my account and selected the anti-spam option. Uninstalling and reinstalling do not help resolve the problem, but it is good to do that if there are any minor problems.
The wscert.der is a Public key and a private key is required, how do I obtain a private key for all 4 email addresses i use ? @morten_andreassen what did you do to fix this issue ?
