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 Outlook 2013, which I presume does not support the modern authentication?

    If your Outlook supports modern authentication, reconfigure your Outlook classic/desktop app to use Exchange type connection to access your mailbox. You can still open the PST file using Outlook classic/desktop app AND access your mailbox at the same time.

    So, how do I access my archived PST files with Outlook.com/Live mail/Hotmail/MSN mail? Or do I have to use one of the third-party clients?

    Jmac

    As of September 16, 2024, NO version of Outlook, past or present, Classic or New, will support a POP connection with Outlook.com/Live mail/Hotmail/MSN mail. Basic authentication was turned off eliminating any connection from any email client program that does not support OAuth2. Further, unlike Gmail and Yahoo, Outlook.com/Live mail/Hotmail/MSN mail, does not allow enabling MFA and the use of an App Specific Password. If your Outlook build is 11601.10000 or later, the only way to use it with Outlook.com/Live mail/Hotmail/MSN mail is with native Exchange server protocol which you get if you let Outlook setup the connection. If you have an older build, you cannot use Outlook at all as older clients do not support Oauth2 at all and will not connect since Oauth2 is now required for Exchange server protocol as well.

    Outlook.com/Live mail/Hotmail/MSN mail still supports POP and IMAP via OAuth2. Outlook build 11601.10000 supports OAuth2 for IMAP connections ONLY, which means you can use it with Yahoo and Gmail on IMAP natively without MFA and an App Password. POP connections with these services will still require MFA and an App Password. In spite of this, Outlook.com/Live mail/Hotmail/MSN mail will still not allow connections from Outlook 11601.10000 or later via IMAP, even though these later versions DO support Oauth2 for IMAP.

    For Outlook.com, POP3 and IMAP are now the province of third-party clients. If you REQUIRE a POP/IMAP connection, Mozilla Thunderbird, eM Client, and Mailbird all support Oauth2 and should be able to give you a POP and/or IMAP connection to Outlook.com/Live mail/Hotmail/MSN mail. All three of these have facilities for importing .PST files.

    Classic Outlook no longer accepts valid Microsoft ID and password on POP or IMAP Microsoft accounts. Just keeps asking me to re-enter. Outlook.com works fine. Microsoft is provider.

    Won’t even let me set up a new profile, as it doesn’t accept password.

    Tried reinstalling Office but still the same.

    I am aware of a lot of people on this forum with same problem.
