I'm using the New Outlook on my new PC. I understand that this app will not read .pst files, for now. For years, I copied and moved my .pst files from PC to PC. I can still read my archived .pst files on my old PC, so not a huge issue.

My question is, what does this New Outlook use for data files, such as for my archives and contacts, and where are they located? Can I create my archive on my storage drive vs my Windows drive, same as I've done forever with my .pst files? I want to be able to copy and move these files same as I did my .pst files. Thanks!

    For the time being, the new Outlook client does not support working with PST files and any related features. Related to that, the new Outlook client only support working with your messages while connected to the server, there is no "offline" mode or local cache. Support is on the Roadmap and will probably come in the next few months, but until then, you will have to use the "classic" Outlook if you want to work with PSTs.

    Hi @Dan Emerson

    Welcome to our forum!

    I agree with Vasil Michev. New Outlook doesn't support any operations on data files. This means that your emails, calendars, contacts, and tasks are stored on the server and not on your local computer. You can't create, open, or move .pst files in the same way that you create, open, or move them.
