Outlook / Exchange Online launch issue

 Re: Outlook 2016 Cannot Open Because of Set of Folders Forking... Yay, I just ran into a WTF issue as well with Outlook. User 1 works fine. Outlook 2016, using O365 Essentials licensing. User 2 is on the same PC and can connect the client via IMAP, but not Exchange. Throws this lovely error. Tried a reinstall, Office removal tool, no avail.

 Full reinstall seems to have fixed it. Outlook itself was apparently corrupt.

Yep, PC is on the domain, email address shows correct domain. Verified the user has a mailbox and proper licensing.

Autodiscover passed by running a connectivity test externally. But after installing a Microsoft analyzer on the user's workstation, it failed and said that https://companywebsite.com/autodiscover/autodiscover.xml is interfering. No idea currently who is hosting their company site (already checked their registrar). I'll have to talk to their marketing individual tomorrow.

HKEY_CURRENT_USER > Software > Microsoft > Office > 15.0 > Outlook > Autodiscover . Within Autodiscover add a DWORD (32 bit Value) with the name ExcludeHttpsRootDomain and set the value to 1.

I only know it as Secure Copy Protocol.

 We had to do some weird voodoo to get our Autodiscover to work in a hybrid scenario.

I honestly can't remember what I had to do the one time I did a hybrid setup, as it's been about 3 years. What did you have to do? I create a folder on the local hard drive stipulating what servers to look to. I also create registry entries to force Outlook to use the local file first.
