I recently got a new computer, and made a backup of all my Outlook .pst files on the old machine. I imported these to the new machine (unfortunately after I already created the email profiles there), and since a few days two of my accounts have not been updated with new mails (even though I can verify through webmail I did in fact receive some new mails).
Checking the mailbox location on the new machine, it points to %user%\AppData\Microsoft\Outlook, and in there, it refers to some .ost file. Ost apparently hints at Offline files, which might explain why the new mails won't show up.
I tried copying my .ost file, followed by removing and recreating the user, but that simply creates a new .ost file. Why would it somehow suddenly switch to that, and how can I fix it so that I will receive new mails again?
Edit: Why the downvote, exactly? I tried describing my issue as well as I could, and provided things I tried. Not sure why that would somehow warrant a downvote.
