i need to access my past sent emails containing 100's hours research over 1000's items, while lost using Outlook Classic.

My laptop was supposed to have Office installed qualifying me for upgrades to windows, etc. After 18months, and numerous downloads, apparently Windows determined i did not quality? as office was only a shell/part loaded version with only very basic programmes. Outlook started to corrupt, and degrade to the point that outwards emails only queued up / inward files also had difficulties.

THEN Windows 11 started to have problems. After many hours with Copilot, trying many alternative solutions, it was that Windows was self-protecting? preventing any repairs. I was advised i need to create a USB boot , loaded with Winnows 11 OS , delete original install and reinstall fresh.

Finally had even more problems, reported to Microsoft, and some diagnostics got Windows operating. too much wasted time, moved to GMAIL !

I hope i am the only one going down this track, but highly unlikely.

I still need to access my old sent reference emails from Outlook. Any advice will be welcomed.

Thanks to everybody. Kind regards, Trevor

    If the old Outlook data was stored locally, the best chance of recovering the sent mail is to find and open the old .pst file in classic Outlook.

    1. Check whether classic Outlook is installed.
      • Importing or opening a mailbox from a .pst file is not supported in new Outlook.
      • If only new Outlook is installed, switch back by turning off the New Outlook toggle, or install classic Outlook for Windows.
    2. Look for the old Outlook data file on the laptop or any backup/USB copy. Common .pst locations include:
      • C:\Users\<username>\Documents\Outlook Files
      • Older Windows/older Outlook setups may also store it under the local Outlook data location.
    3. Copy the .pst file to a local folder before opening it.
      • This is safer than opening it directly from removable media.
    4. Open the file in classic Outlook.
      • In classic Outlook, go to File > Open & Export > Open Outlook Data File.
      • Select the recovered .pst file.
      • Outlook should add it as a separate folder tree, where old Sent Items, mail folders, contacts, and calendar items can be browsed.
    5. If the goal is to move those old sent emails into the current mailbox, use classic Outlook to copy the items from the opened .pst into mailbox folders so they sync online.
    6. If the file opens but Outlook is unstable or reports corruption, try Outlook repair steps:
      • Start Outlook in safe mode: press the Windows key, type outlook.exe /safe, then press Enter.
      • Repair the Outlook profile or create a new one.
      • Run the Inbox Repair Tool on the .pst file.
      • If Outlook itself is damaged, repair Office from Windows Installed apps / Apps and Features using Modify.

    Important limits:

    • A .pst file contains locally stored Outlook data, including POP account mail and exported mailbox data.
    • Moving a .pst file to another computer does not transfer the email account settings.
    • If no old .pst file exists and the old account was not keeping mail on the server, recovery may not be possible from Outlook alone.
