Import a pst file into new outlook

An unbelievably stupid solution I agree. One upgrades to the New Outlook and finds that one can't import old emails without reverting to Old Outlook. Either their development team is on some substance or we may be heading for a cunningly planned increase in subscription to get our files into the New Outlook. Poor show Microsoft.

What if the classic/new toggle does not exist?

Near as I can figure out - if the Option to Switch to Classic is not available and you are using the latest Outlook (New) from the MS Store or as installed/updated in Windows 10/11, then you do not have Microsoft 365 Outlook Classic installed. The Online/Cloud Outlook does not qualify, you must have one of the MS 365 subscriptions in order to get and install the MS 365 Outlook Classic. Obviously, older MS Office Outlook versions 2016, 2013, 2010, etc also do not trigger the "Switch to Classic" option in the Outlook (New). As I stated previously, in 2023 the MS Office 365 version of Outlook had an update that added a toggle between the normal/classic and a brand-new User Interface that MS was previewing. At some point the MS 365 Outlook was updated to only use the New Interface and that toggle within the MS 365 Outlook was removed. Also, at some point the stand-alone, shipped with Windows and avail from the MS Store version of Outlook (new) became available or your installed version was updated to the latest version. I suppose that an option was included in this new stand-alone Outlook to show the "Switch to Classic" button if the MS 365 Outlook was installed on the desktop. Remember that the MS 365 "Office" version of Outlook, which requires a Subscription is totally different than the stand-alone email client that ships with Windows, and that Microsoft name-changed from MS Mail and Mail and Calendar to Outlook (new). Remember, there have been two "Switch to Classic" buttons - the first was the toggle that allowed you to preview and switch back and forth between the normal MS Office 365 Outlook user interface and the new user interface that MS was previewing prior to the early 2024 switch to the new MS 365 Outlook (classic) user interface. The second "Switch to Classic" was a one-way button added to the Windows email client Outlook (new) to launch the MS 365 Outlook Desktop (classic) if both are installed. In order to get back into the Windows email client Outlook (new) you need to re-launch it. You can have both installed, configured and running, though the Windows Outlook (new) does not leave copies of your Pop3 emails on the server and there is no way to enable that, so you may have trouble keeping the two local mailbox stores synchronized - switching to IMAP will solve that, since the messages are left on the server. At some point, MS may remove the "Switch to Classic" button from the Windows email client version of Outlook (new) but, as I said it does not do much except launch the MS 365 Outlook (classic) desktop app and should not be confused by references in older Help articles that indicate the presence of a "Switch to Classic" toggle in Outlook - they are talking about the older MS Office 365 version of Outlook from before the change to the new MS 365 Outlook user interface.

Just bought a windows 11 new computer. There is no toggle switch on my new version of outlook. How do I dump this and get the old version. I have lots of saved emails stored on my old computer. I have exported the PST file to a portable hard drive and need to import this to my new outlook.

Phillip, only the Outlook Classic that comes with "MS Office" - standalone or MS 365 - has the ability to use PST files at this time. There is a possibility that the Outlook (new) from the MS Store or pre-installed with W11 will get updated to use PST files - I have seen March 2025 but who knows for sure. See my older post below for more detail. I am still using my Office 2013 for just this reason, until it makes sense to switch over to MS365 or possibly the latest standalone Office version. I have also looked into some utilities to batch convert my PST stored messages into PDF files, since printing each as a PDF would take forever.

It is possible though there is usually some cost for the utility if you want the better automation and organization capabilities than the Free or trial version.

I hope this answers your question, though it may not resolve your issue,

Tim
