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?
Using New Outlook on Windows for personal email, calendar, and contact management
Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
How has it stopped working? What kind of account(s) do you have, POP, IMAP, Outlook.com/Hotmail/Live mail/MSN mail, or Exchange Server and who is(are) the provider(s)?
Problem is that “Classic “ outlook has stopped working! I cannot login and haven’t been able to do so for months!!
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. :-)
Outlook New is the web-based client that is replacing the Windows 10/11 Mail and Calendar app and is supposed to eventually replace Classic Outlook Desktop. Classic Desktop is the Outlook that has been around since 1998, is part of Office 365, and uses .PST files.

That is really strange because I have all 3 mail apps installed, Outlook 2016 (part of Office 2016 Pro suite), Mail app (default Windows 10 mail) and Outlook (new) app. I can use any app I want. Clicking each app launches that exact app. It does not take me to Outlook (new) app at all. Never.
I don't understand why people are complaining about being forced to use Outlook (new). It may have something to do with the environment. I sign in to Windows Active Directory domain in the LAN and my account has no Admin privilege.
