I have twenty years of history in various .pst files. When I first started using Outlook, my single .pst file and all my folders got too large and I was instructed to move some of my folders into new .pst files. These .pst files contain lots of important emails and historic records attached to emails. So I filed all the emails into various folders within various .pst files.
If Outlook will no longer support .pst files, how will I be able to access the .pst files? I understand that Microsoft will no longer support “Old Outlook”. So what can I now do to be able to access these various .pst files? Should i go back to what I was doing originally and move everything from .pst files into folders within my "root" Outlook email? That would put about 4.5G of emails into my New Outlook. How will that work?

I wouldn't use an unfinished product (Outlook new). It's still under development and full of bugs. No one knows how PST support is going to be when it's available.
From the Microsoft 365 Roadmap page I linked earlier:
The initial version of PST support in new Outlook for Windows will enable users to open "*.pst" files (a.k.a. Outlook Data Files), read all e-mail messages within the "*.pst" file, and search e-mail messages within the ".pst" file. This initial support is limited to Mail items and is read-only. All Calendar, Contacts, and Tasks data saved in the "*.pst" files are still there, but they cannot be accessed in this initial version. #newoutlookforwindows
FWIW, both versions will install and run at the same time. Originally, I clicked the toggle and Outlook new installed. I went back into Classic and turned the toggle OFF again. I now have both installed, both run, and the toggle in Classic remains OFF so Outlook New only runs when I launch it.

Thanks. I will stick with classic for a while. I'm an old fashion Outlook guy. :-)
This answer is a non-starter. The main reason people export to PST is because of email storage limitation of 50Gb and 100GB if you use In-Place-Archiving. You can't just put all that historical mail back in outlook!!! The whole point of having a PST file is to hold historical email records for referencing in the future. So being able to mount the file is crucial for I would say every business on the planet not to mention Governments.
No matter what the reason to keep .PST files, they are very important for us. A temporary solution (temporary = forever? ) is to keep both the Old Desktop Client Outlook and the New web based Outlook working side-by-side, each with its own data. All communication with outside email servers would be handled by the New Outlook, having all possible security features, while the Old Outlook should serve as a database, using your .PST files. You can freely import/export between the Old and New Outlook. Just my 2 cents.
I agree, but alas, yes, Microsoft, in its infinite wisdom, has gotten rid of .pst files in newest Outlook. I am currently in a lawsuit and need to access older emails that I filed into .pst folders going back years. Microsoft needs to come up with a better solution.
