Thanks so much for a great article! I was wondering if you can give any troubleshooting on this part:
Your copy confirmation should always indicate that you are copying matching directories (e.g. Local Folders -> Inbox to Gmail -> Inbox). Any time it doesn’t match up (e.g. Local Folders -> Inbox to Gmail -> Inbox -> Inbox or any other odd variation) you need to cancel the process and redo the Copy To operation.
When you say "redo the Copy To operation", does that mean simply going back into the Local Folders, right-clicking, choosing "Copy To..."--> "destination@gmail"-->"correct folder" again? Because I am getting this exact error over and over again, and I don't know what to do differently. Each time the confirmation box tells me it's "firstname.lastname@example.org --> folder --> folder."
And if I go ahead with the copy, it does copy there, because if I search for an old-gmail email in the new-gmail, it will find the searched-for email. However, I can't find those emails simply by navigating to the folder. If I'm looking AT the destination folder in the new-gmail folder tree it doesn't appear to have any emails in it, nor any sub-folders to expand. It's very confusing.
