We have a customer with Office 2007 and needed to set up an Office 365 account. Auto Discover was looking for the server, so I put in “outlook.office.com”
The following web link gave great detailed instructions for manually configuring the mail server.

I had to install an older copy of Office 2010 Pro Plus on a Windows 10 machine that got reset because Windows Automatic Repair was stuck in loop.
I installed Office and started with adding their Godaddy Office 365 account into Outlook. During the install I ran into error 1719, but got past it. Here is how I did it. Fix error 1719.
Outlook couldn’t just set up the email. Godaddy has a program specific to setting up their Office 365. I found the program here.
https://www.godaddy.com/help/outlook-setup-assistant-windows-set-up-email-automatically-19938
The program ran into issues.
When I tried to run their link “Open Office Setup” I got the following error.
I needed to upgrade the Outlook 2010. This lead me to this page.
I downloaded and ran the update “KB 2687521“. After I ran the update I ran the Godaddy assistant again and I got this error.
This time when I clicked to “Open Office Setup” the setup opened and ran. Outlook opened and I was able to get the two email accounts set up.

We had a customer get their Office 365 email account compromised / attacked. The password was reset and the user could send email she just didn’t receive them.
I went into her online Office 365 account and verified the issue. This page lead me to the fix.
Their advice to check the mail flow helped me solve the issue.
You need to go into the individuals account and click on the setting gear icon in the upper-right: 
Scroll down to “Your App Settings” and click on “Mail”.
On the left-hand side menu, in the “mail” section, click on “Inbox and sweep rules”. Go through the rules to see if there is a rule that is causing your issue.
The attacker set up a rule for the emails to go to the “deleted” folder. A common practice.

We had a rough time with a customers Outlook 2016. It wouldn’t start and would give us the “Cannot start Microsoft Outlook” error. We repaired the OST and reinstalled Office 2016, but this didn’t fix the issue. It would seem like the error was fixed, but after a restart the issue would come back.
We used the following link to lead us to the right resolution.

We then downloaded the repair tool from this page.
We ran the tool and got the following message.
Which lead us to turn off IPV6.
