They will be in your Local Folders. If Local Folders are not visible in the left side-bar with the other folders, you can enable them in Menu > Tools > Settings > General > Show Local Folders.
Thanks. Local folders is selected already. The local folders show in the left hand pain. They are inbox, outbox, sent, trash, junk. Only junk has any content - 1 entry.
You can search for one of the imported messages, then when it is displayed in the search result, right-click on the message preview and choose Properties. That will show which folder it is stored in.
If there are no results for the search, do the import again, but make note of the destination selected in the import dialogue.
I messed around adding and deleting holiday folders in various places. Suddenly all outlook folders appeared! Then your latest response arrived. All now OK. Thanks for your help.
