As Reddit user Odd_Raisin3205 asked: My father recently upgraded to Windows 11 and has over 15 years of Outlook email archives. All data is stored inside a PST file that is larger than 1GB. He does not use a Microsoft account or an Outlook.com email address. Outlook now says a Microsoft 365 subscription is required to access PST files. Is there a way to import PST to new Outlook without Microsoft 365 while keeping all emails intact?

However, the newly developed Outlook may have some limitations concerning PST import. In case the importing process is not possible using its built-in options, it is recommended to try a specialized tool, MSOutlookHelp Outlook Converter, for accessing and transferring the required information.
If the Outlook program cannot open your PST files, you can always consider using alternative options that depend on what exactly you want to do.
In case your archives include many emails, you may choose a PST converter, as it will allow you to view everything without using Microsoft applications at all.
Microsoft allows the import of PST files using Classic Outlook. The new Outlook experience doesn’t provide the PST import facility provided by the Classic Outlook version.
A way around this problem is to revert to Classic Outlook, perform the PST import operation, and then use Outlook to view the mailbox. But you will have to install Outlook to get the process done.
With the native procedure being quite tough, there may come the need to find an easy method for accessing the PST files. MSOutlookHelp Outlook Converter offers you a solution to open, migrate, and convert your PST file without using Outlook’s import functionality. The program works with large PST files and ensures that the emails, attachments, contacts, and folders are preserved during the entire conversion process. You can also convert PST file to MBOX for cross-platform access.
