where exactly is the pst file? It seems to be saying it cannot reach it, like it is on a server it doesn’t have access to, or group policy is restricting it, or …
Can you move the pst file to you own documents folder and see if that helps?
Thanks for suggestion. The file is saved locally. I’ve even tried re-exporting the file and also copying a small number of emails to a new blank local pst file and I still get the issue.
I’ve found a workaround - I imported the PST file to a local folder and then copied across to the folders of the IMAP folders. The error message seems to be related to eMclient trying to import directly into a mail account folder. Hopefully eMclient can fix this.
