Windows Mail sync error - Error 0x80072726
Hi,
Since upgrading from windows 8.1 to 10 I am unable to sync any of my email addresses with Windows mail. Every time I click sync, it tries and after a while returns an error code: 0x80072726. I have tried deleting the accounts and recreating them, tried various types, hotmail, gmail etc but nothing works. Googling the issue seems to show a number of users with the same issue, some suggesting a firewall issue.
I have just tried switching off Bitdefender firewall and it now works. Anyone know which rules I need to set up in bitdefender rules to allow mail sync?
