If you can follow Daniel's instructions (earlier in this thread) and revert to a previous version of Office without removing & re-installing, you have a much better chance of keeping Outlook intact.
I'm confused. Are you saying I can revert back to a prior version
without first uninstalling the current version?

Tom,
Yes.
Above is a screen-shot of the section of this thread where I found the link to Daniel's article (with more links from within the article) about how to revert
without reinstalling.
I had a few days I could endure without being able to access my business' MS-Access databases, without suffering too much inconvenience. After the Outlook nightmare we endured last year I elected to sit, wait and watch this thread to see what progress might
be posted in solving this Access issue.
When Daniel posted his instructions I read (and saved) them all, printed the pages I would need, took careful notes about my system and Office installation, cleared my schedule for an afternoon and went to work. I disabled Automatic Updates and followed
his instructions to revert to the last-known stable build:
February 1, 2018, Version 1801 (Build 9001.2138)
is what he recommended, and what I reverted to.
Access has been working for me for the past few days.
One related note. For those who need Office-style applications but do not need total and complete compatibility with the latest Office features, and who are upset by the subscription fees and support charges from Microsoft, consider switching to OpenOffice
from the Apache Software Foundation. It is an Open Source application suite and it is
free! {That is NOT a typo.}
"Base", "Calc", "Impress" and "Writer" are the OpenOffice equivalents of "Access", "Excel", "PowerPoint" and "Word" in MS-Office. The more trouble I have with MS-Office, the better Apache OpenOffice looks. I'm studying it in my spare time and I'm saving
my files in formats that can be easily and directly imported into OpenOffice.
