When trying to open Outlook 2010 after a fresh install on Windows 10, I was receiving the error “Connection to Microsoft Exchange is unavailable”, as well as an error that the .OST file was not valid.
This would cause Outlook to freeze, and if I made it through the freeze, it would show me a prompt to update the Exchange details for my account. Changing the settings did solve the freezing problem.
The Cause: When setting up Windows, I used my email address as the new Microsoft account to log into the machine. Windows oh so helpfully assumed that email was tied to an Exchange account, and auto-created an email profile with Exchange info for that email account.
Every time Outlook opened, the attempt to connect to that “Exchange account” would make Outlook take a looong time to open, freeze things up, and generally make you hate life.
Even if you add other email accounts and make one of the other ones the default, you still can’t delete or modify this oh so helpful account, so Outlook will continue to freeze up.
If you asked my father what Dave’s favorite music is, he would have told you what his favorite music is, and (importantly) he’d think he’s answering the question. If you ask someone why Dave works so hard, he’ll tell you what he aspires to. He might say Dave does it to get rich. That wouldn’t tell you anything about Dave, but it likely tells you something about him. This is important to understanding disputes, and is why listening is so important. For example, the US thought North Vietnam was fighting because they were part of a global communist alliance to defeat the west. The Domino Theory. Because we were at war against that. The Vietnamese were actually fighting a war of independence, and were puzzled why the US, a former colony that fought for its independence, was fighting them. Moral of the story: Unless you ask, you probably don’t know why someone is doing what they do.
