Cant move emails to pst files

Hi,

Yes, this is a known issue many users have recently started reporting with the New Outlook. PST support was added earlier, but at the moment the functionality to move or drag items into PST files seems to be broken. Emails often bounce back into the IMAP inbox, exactly as you describe.

A few things you can try:

Check for updates – Microsoft is actively rolling out patches. Go to File > Office Account > Update Options > Update Now to make sure you’re on the latest build.

Use the classic Outlook – For now, only the classic Outlook app (from Microsoft 365 / Office) fully supports working with PST files. If moving emails to PST is essential, switching back is the most reliable workaround.

Provide feedback – In the New Outlook, go to Help > Feedback and report the behavior. The more reports, the faster Microsoft can prioritize a fix.

Unfortunately, at this stage it looks like a regression/limitation in New Outlook rather than a settings problem on your side.

I've just started having the same issue in the last few days so does appear to be related to an update. Ability to use pst folders was one of the features I waited for before trying new outlook so now switching back to classic.

I recently moved to 11 as well and had the same issue.  Because there are several other things I do not like about the new Outlook I decided to switch back to "classic" Outlook (you have that option).  That may not be the solution you are looking for but it does work.  Sidebar - my next feat is to figure out how to get Outlook to default to classic when I open it because it always wants to start with new Outlook and every time you turn it off they ask you to do a survey of why - frustrating after the first few times....................

The PST is most likely corrupted. I would create a new one,  you can do so by exporting the current PST to a new one and name it something else. It also could be too large, or just very old. If it's too big (49 gigs) then you need to create two PST and manually move data around. It's time consuming but PST do tend to get too big and that's the option I help with. 

We are having this issue in our company as well.  We were forced into using the new Outlook due to using a Telus email, but we had been using a .pst file for many years.  Since the .pst is only partially supported in the new Outlook, it now acts as 'storage' and we have been moving emails we need to file into the .pst.  A few days ago they started bouncing back out, even though we get a pop up asking if we want to move the email.  Very frustrating and we hope that Microsoft fixes this, and all the issues for those of us that have been using .pst files in Outlook for years!

This looks like a New Outlook issue, you can rollback to the classic Outlook or try using OWA.
