VPN and Outlook 365 - Can't send/receive email

I run Windows 11 Home and Office 365 with Norton 360.

My Outlook email accounts are configured to use POP3/Port 995 for Incoming and SMTP/Port 465 for Outgoing, with SSL/TLS for both. This configuration is per the ISP's specification, and one I have used for many years..

I just tried enabling the VPN and have run into the same errors with Sending and Receiving that others have reported.

Here are the change I have tried in order to fix the problem:

1) Disabling the Kill switch

2) Adding Outlook.exe to the Split Tunnel exclusion list.

3) Disabling AntiSpam

4) I attempted to add Ports 995 and 465 to the Protected list, but the program would not allow that.

Is there anything else I can try to get these two products to work?

Re: VPN and Outlook 365 - Can't send/receive email

Norton Support investigated this problem by remote sessions on my system. They tried some things and captured some files and said they would get back to me. They did call a few days ago and left a voice message, but the speech was so rapid my old ears could not understand it. 

Today I was applying some opsys and driver updates on one of my Win 11 Dell XPS 13 laptops. After doing that I ran LiveUpdate and restarted the system. On a hunch I enabled VPN and started Outlook 365, just to see if anything changed.

This time Outlook Send/Receive worked without error! And it works with or without the Split Tunneling exclusion of Outlook.exe. I was also able to recreate this success on my backup Dell XPS 13 laptop.

Although I haven't heard this officially, my guess is that they created and implemented a fix, which I picked up via LiveUpdate. 

Whatever happened, I now consider this problem to be resolved.

Thanks. I tried to protect Ports 995 and 465, but the Norton program wouldn't allow it, explaining that the ports are used by programs other than email..
