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?

    OK so I've just started using new Outlook and if I was to import my email archives ie pst files in order to do a search, I would have 32GB of data in my new Outlook which is silly. What I would have to do is import each archive separately and then delete same but it's not clear how I do that? Equally, my emails are archived within each pst file in different folders. Are the folders preserved when I import them?

    If you do not want to subscribe to a paid Microsoft 365 plan to get Classic Outlook, then you might want to consider buying a license for Office Home & Business 2024. https://www.microsoft.com/en-us/microsoft-365/p/office-home-business-2024/cfq7ttc0pbm7 This includes Outlook 2024. The latest version of the full featured, Classic, desktop, stand alone, perpetual license Outlook.

    I have avoided converting to New Outlook specifically because it won't support my years' of PST files.

    I was dismayed this morning on opening Outlook that it prompted me again to switch to New Outlook and then told me something like:
    "If you avoid the switch now, you will automatically be switched the next time you start Outlook."

    After reading much of this thread I did a search (in Firefox using DuckDuckGo):
    "is there something other than outlook that can read pst files"

    That returned various hits including one at Coolutils Converter Blog titled
    "8 Best Ways to Open a PST File Without Outlook in 2024"
    The link to that is: https://www.coolutils.com/blog/ways-to-open-pst-file-without-outlook/

    I haven't tried any of the methods there yet but figured I'd share it here for others.

    Unfortunately this results in an "unknonw error" when attempting to move messages to / from archive PST files.

    This will become a major showstopper and will need to move to ZOHO, VNC or something other than Microsoft - with >20 years of emails that will need to be able to access. It's untenable to put these back into the root as one of your suggested remedies - so would respectfully suggest to inform dev team that they need to figure out a way to bridge and maintain continuity.

    Thanks for trying though.

    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.
