How can I mount a data file (pst) in new outlook. In the classic version this is doable through the File menu which is not available in new outlook.

I have the same complaint. I have years of PST files that are part of a projects that required emails to be stored with all data for each specific project. Not having access to those PST files will be a real problem.

New Outlook does NOT have "FILE".

Please go not give answers that are NOT possible!

How do we actually import PST file contents into new outlook. and don't say "Import", the option does NOT exist.

Per this document, PSTs are not supported in the preview but will be coming soon.

Hi anon151,

Good day.

Thank you for posting to the Microsoft Community. We are glad to assist.

I understand your concern regarding mounting a PST file in the new version of Outlook. Unfortunately, the new Outlook for Windows does not currently support direct access to PST files. However, I’ll provide you with alternative steps to achieve your goal:

Import from an External PST File:

• Click on File in the Outlook menu bar.
• Select Open & Export > Import/Export.
• Choose Import from another program or file and click Next.
• Select Outlook Data File (.pst) and click Next.
• Browse to the location of your PST file and select it.
• If the PST file has a password, enter it and click OK.

Use OST Files:

• The new version of Outlook uses a different file format called OST (Outlook Offline Data File) instead of PST.
• OST files serve a similar purpose as PST files and store email messages, contacts, and other data.
• When you connect your Outlook account to an Exchange server, it automatically creates an OST file for offline access.
• You can’t directly create an OST file, but it’s automatically generated when you set up an Exchange account in Outlook.

Provide Feedback:

• Since the new Outlook is still under development, many features are not fully functional.
• If you have suggestions or need specific features, you can provide feedback by selecting Help and choosing Support orFeedback.

In summary, while direct PST file access is not available in the new Outlook, you can import data from an external PST file or work with OST files.

I hope this helps let me know if this is contrary to what you need, I would still be helpful to answer more of your questions .

Best Regards

The frustration is real - and I agree, it feels like a money-grab.

I have M365, but use it through the desktop application as the cloud version lacks features I use daily. Still, mailbox sizes are limited, and archiving for many businesses is a must. In this world of electronic delivery of documents, mailbox capacity depletes rapidly - so offline mailbox for archival purposes becomes a must. (Ah, but that too can be purchased for a price - reoccurring of course). Nah, thanks - I don't mind doing the work and facilitating the backups, but to completely remove my ability to do so - that's unwarranted.

If MSFT wants to sell the service as a convenience, and people are willing to pay for it - great - good for them. But if people want the ability to save their items themselves, MSFT shouldn't remove the ability to do so.

I am back in the prior version - and was able to restore my offline mailboxes for now.... till it gives me trouble yet again.

Hello Misty! Thanks for your reply and interest.

You mention you are back in the prior version and were able to restore your "off line" mailboxes.

I can still open my stand-alone Outlook which I have used for years buy now it keeps telling me via Windows Security pop-up it needs my password. Everything I have tried I get the same annoying message! I used to be very well organized with folders which I can still see but I cannot copy them over, forward them OR do anything with any .pst or.ost files created. This is making me a little crazy!

I am a retired UPS Manager with Information Services background and have relied on Microsoft Outlook since we used an internal application named "SYSM". It was limited and truthfully looked prehistoric but at least it worked!

If you would PLEASE share how you reverted back to the ability to access your folders...I could not THANK YOU enough! I would happily send you a Bouquet of Roses!

I look forward to visiting with folks that have similar issues! Be Safe....Tom
