Accessing Outlook .pst files in New Outlook

Anonymous

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?

    Hi blennerhaset

    Short answer is no, you cannot have a pst file or POP3 account in new outlook. I have tried, you can try to set it up using the qdvanced settings when selecting new accounts, click cancel when it tries to auto negotiate with an email server.

    You have to use outlook classic for pst/pop3 accounts and the new outlook for imap only. There is nothing microhard are doing about it and they dont care about us, maybe back in windows 3.1 days they may have cared about us, but now we are force fed.

    Installing Outlook New has no effect on Outlook Classic, they will co-exist and run at the same time. No O365/M365 updates remove Classic Outlook, if you had it, it should still be there. Do you find OUTLOOK.EXE with the rest of the M365 apps Word.exe, Excel.exe, etc.) under this path?

    C:\Program Files\Microsoft Office\root\Office16

    Do you have both icons in your Start menu?

    i just bought a new DELL laptop with Windows 11 and new outlook and there is no way that I can find to move my old outlook pst file from my old laptop. some MS admin in this thread claims you can do it by switching to "classic outlook" but when I try that I get a message saying you can't use classic outlook on a new pc. sheesh!
