I responded to the popup requesting that I upgrade from version 6 to version 7. My email and contacts showed up in the new version, but my calendar, which was under Local Folders, is gone. The new calendar is completely empty. This is especially upsetting because I don’t know everything that was in it. (That’s why I used a calendar program and did regular backups!) Is there any way to get my calendar back? I tried importing Local Folders from version 6 but got nothing.
Same problem for me…my calendar was not imported from the old version when I upgraded to version 7
Here is the error message I get when trying to import Local Folder Calendar from eM Client 6
