Later versions of Outlook do not have the ability to create a profile without a working email address. Such profiles are commonly used when Outlook is being used only to open PST files that have been created as archives.

Running this command will create such a profile:

Outlook.exe /PIM <profile name>

So, to create a new profile called “snapshot”:

Outlook.exe /PIM snapshot

Remember that Outlook’s search index will have to be built for the data file(s) associated with this new profile so the search function will be limited at first.

The shortcuts located at the bottom of the folder list in Outlook 365 (Mail, Calendar, People, Notes, etc.,) moves to a narrow vertical bar on the left with some of the shortcuts, such as Notes and Folders, missing.

For now, the only fix I have found is a registry entry:

HKCU\Software\Microsoft\Office\16.0\Common\ExperimentEcs\Overrides

Add/change 32-bit Dword:

Microsoft.Office.Outlook.Hub.HubBarcollapsible = 0
