I have been an XP user for (many) years and have just bought a new laptop with Windows 7 Home Premium (64-bit). I successfully imported all my old OE mail folders into WLM, appearing as "Storage Folders" in WLM under "Imported Folders". So far no problems.
I have traditionally separated my OS and data files (including e-mail) on separate partitions so I used the trusted method of moving the Mail Store location. As expected as soon as I closed WLM, all my e-mails & account details were moved to the new location I specified.
Next time I booted the laptop every time I closed WLM, I kept getting a message telling me the files in the store could not be moved. On checking the mail store location, it had reverted back to its original location in C:\users.....
As I did not know which store WLM was actually using I created another new directory and moved the mail store location again. It seems to be working now but I have 2 lots of folders, one set in the original default location and one in the new specified location.
Has anyone come across this issue (I have searched and not come up with anything) and assuming the problem does not manifest itself again, am I safe to delete the files from the default location?
