The committee made a decision not to pursue backward compatibility, which probably made a lot of technical issues easier but leaves us with difficult problems now that we’ve procrastinated and there’s no time to ease into things.
Traffic running on IPv6 equipment is invisible to IPv4 equipment in almost every way. “The problem is, IPv6 is not particularly compatible with IPv4. Here’s what I had to say about procrastination: I wrote two articles to prepare everyone for the IPv6 revolution: First Rumbling Of The Coming IPv6 Transition and IPv6 And Really Large Numbers.

The result is that you will likely not notice any difference whatsoever if you disable IPv6 today on a Windows computer in the United States. It will require such a disruptive shift at all levels that everyone affected has been procrastinating and making loud LA LA LA noises for quite a long time. Its successor, IPv6, has important technical advantages and it will have a large impact on modern networking when it is fully implemented. The original address system, IPv4, is still in widespread use, and it’s used almost exclusively in the United States. There are two Internet Protocols used to carry information around the Internet. If you get back IPv6 addresses, then you might fix the problem by disabling IPv6. Try pinging on a computer where Outlook is disconnected. The chances are it will resolve itself eventually but that might be anywhere from an hour to a day to never. It can start in the middle of the day while the computer is logged in, or it can start after the computer wakes up or is rebooted. It happens to computers that have been happily connecting to Office 365 for weeks or months or years. It’s limited to the Microsoft Office 365 servers other IPv6 DNS name resolution works fine. When that happens, Outlook cannot connect to the Office 365 servers. (3) Is this a good idea? (Spoiler: No, but it’s easy and it works.)Īs far as I can tell, some computers stop being able to resolve the IPv6 DNS address for.

If you’re in that position, try disabling IPv6 on the network adapter handling the Internet connection.

The company credit card used for Office 365 hasn’t expired, the user password hasn’t expired, the computer’s Internet connection is normal, the wi-fi is working, all the usual suspects have been eliminated. Phones are still sending and receiving mail. Outlook shows Disconnected or Trying to connect.The specific problem that I’m describing happens this way: I’ve dealt with it several times in the last year or so, mostly in the last few months. Outlook 20 can occasionally lose their connection to an Office 365 hosted Exchange mailbox. But if you’re not sure, don’t do anything to your computer without the support of your trusted IT support person.)
