Outlook worked fine for many years, stopped a few days ago. I have been unable to figure it out so far. Help would be greatly appreciated. I have the same exact problem on 2 computers. I am using Comcast suplied Norton AV
Task 'XXXXXXXXX2@comcast.net - Receiving' reported error (0x800CCC0F) : 'The connection to the server was interrupted. If this problem continues, contact your server administrator or Internet service provider (ISP).'
I experienced the same.
You should delete in Outlook all add-in including integrated plug-in of Norton AV.
When in Outlook you select Tools > Trust Center > Add-Ins ( second line in Trust Center, in the left pan ) you should see whether Norton AntiSpam Outlook Plug-in ( in right pan ) is enabled or not.
You can disable Norton AntiSpam going directly to Norton AV settings AntiSpam > Client Integration finding there: Address Book and Email Clients
turning the switches on/off to off. Later by rebooting your PC you can again in Outlook recheck whether this plug-in was disabled.
Please disable Norton Plugin using the steps below
Under Detailed Settings, click AntiSpam.
On the Client Integration tab, under Email Clients, click on the slider next to Outlook to turn it Off.
Click Apply, and then click Close.
Exit all the programs, and then restart the computer.
Check with outlook after this if you are gettin any error messages.
