Microsoft SUCKS at communication! Always have and don't seem to want to change their ways.
I heard about the fix from Karl Donaubauer. I never heard about it from Microsoft.
Even if you check the official page on the subject, https://support.microsoft.com/en-us/office/access-is-unable-to-close-and-leaves-lockfile-active-b2dce32b-b8b0-41f1-ba40-7876e524d9da , as of the writing of this reply, there is no mention of the new build or that it resolves the issue. They still have it indicating to use the TL workaround (with no instructions on how to create them, especially for runtime users!).
All I can say, is I totally relate to everyone's frustrations. We, the MVPs, have brought the same issues up to Microsoft for years, and yet here we are, nothing ever changes. That is why I try to post such issues on my own blog as it takes Microsoft days to publish anything, which is sheer madness. The problem is I'm not being paid and I end up spending a tremendous amount of time doing so.
I don't know anymore than you why Microsoft is so slow, unresponsive. Why even when they internally know about the issue, the support agents don't and are still advising users incorrectly. ...
This, and many other bugs, clearly illustrates just how disconnected Microsoft is from its community and how poorly managed their fixes webpages are. It has also clearly demonstrated major internal communication and testing flaws that exist in the testing and release processes which have been ongoing for years now, with no signs of ever being fixed. Don't expect anything to change!
Fun times we live in.
