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?

    I have the premium version. But why would I use cloud storage when I have 25 years worth of emails in .pst files working perfectly in the Old Outlook? And backup up . Anyways, how does it work? I have 13 .pst archived files dating back to 2000. Each set has 10-20 folders. How does it merge those in? For instance, if I have a folder called 'Finance' in each .pst file will i end up with 13 'Finance' folders or will they all merge into one?

    I am sorry if this is not timely, but I am also very worried about PST file support. I too, have years of backups with critical information stored, locally, on my own hardware.

    By 'backup', are you being clear that my backup(s) can be made to local hardware/disks? or is this forcing a backup to the cloud? Its critical to me that the information stay local on my own hard-drive(s). Is this possible? If so, can you please go through the steps to do this?

    I am afraid to upgrade to the new outlook until I can successfully import my PST files and move ALL of my data to another location locally if the PST support goes away. Its now end-June 2025 and I haven't seen too much.... was expecting full disclosure on how to do it by End-Year 2024.

    Please be very clear about what we can do, as I am sure that there are many people in this situation. (again, I dont want to rely on cloud storage, and need to get ALL my data moved back to local storage /hardware on my site in a format that will be readable / usable for the near future....

    thanks
