I recently upgraded to Office 2016 Preview from Office 2013. I had several POP / IMAP and Exchange accounts that all worked fine prior to the upgrade. After the upgrade the POP / IMAP accounts work fine but non of the Exchange accounts work. I got the following message "Outlook cannot log on. Verify you are connected to the network and are using the proper server and mailbox name. The Microsoft Exchange information service in your profile is missing required information. Modify your profile to ensure that you are using the correct Microsoft Exchange information service" Ok, so deleted the account and tried to set it up again however, under "Add Account" there is no longer an option to set up an Exchange account. There are only two options: 1) Outlook.com or Exchange ActiveSync compatible service or 2) POP or IMAP. The Microsoft Exchange Server or compatible service option is missing?

I had the same problem as the OP. Here's how I got Outlook 2016 to work without needing autodiscover.
I could still remember the name of the Exchange 2010 CAS Array that my Outlook profile was configured to connect to under Outlook 2013.
First I pinged that server to get the IP address of the server, then I opened my the file c:\windows\system32\drivers\etc\hosts in notepad as an administrator and added the following line:
'IP address of the server' autodiscover.myemaildomain.com
i.e. 192.168.1.123 autodiscover.mydomain.com
Then I saved the hosts file and reopened Outlook 2016 and everything connected fine.
This will probably only work inside your companies network. It relies on the casarray/server hosting your mailbox having autodiscover running on it even if the DNS records aren't published. If you don't know your casarray's name find a colleague who has Outlook 2013 still running and look at the name of the server that's configured in their profile.
Good luck.
How to find is autodiscover running on mailbox server or not?
You can open a browser and enter the URL https://cas_server_name/autodiscover/autodiscover.xml and see if you get any XML response but the easiest way is to try what I've suggested and see if it works. If not it's either been locked down by the administrator or it's not running/configured.
You need to query the CAS (client access server) not the mailbox server but that's the server that would have been configured in your old Outlook 2013 profile.

Why should end users have to enter programming code to get applications to work right? Doesn't our subscription to Office 365 (formerly purchase price of a license) pay for that kind of engineering?
