Microsoft Outlook hangs at "Loading profile..." (solved)

Problem:

• Outlook hangs at blue splash screen with "Loading profile..." and never opens.

Software involved:

• Win 10 64-bit 10.0.10240
• Office 2016 64-bit 16.0.4229.1029
• IMAP account hosted with GoDaddy (imap.secureserver.net) - only item in profile (.OST backed, default settings)

Solutions that did not work:

• Creating a new Outlook profile
• Clearing out all MAPI config from the registry (renaming HKLM\SOFTWARE\Microsoft\Windows Messaging Subsystem )+reboot
• Deleting all Outlook folders under %USERPROFILE% dir
• Renaming out all Outlook registry settings under HKCU
• Doing a full repair of Office 2016
• Setting up under a fresh user account
• Starting Outlook with /SAFE parameter
• Disabling IPv6 (create DWORD HKLM\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\DisabledComponents set to 0xffffffff)+reboot
• Clearing out Windows Search (ControlPanel->IndexingOptions, unchecking Outlook, 'Delete+rebuild' on advanced tab)

Solution that did work:

• Disconnecting the network, then reconnecting when Outlook was open.

  Launch Outlook, wait for blue splash screen stuck at "Loading profile..."

  Launch an Administrator command prompt. (Start, type CMD, press Ctrl+Shift+Enter, say Yes.)

  IPCONFIG /release at command prompt.

  Outlook opened up

  IPCONFIG /renew at command prompt.

  Clicked "Send/Receive All Folders" - sync completed normally.
