I created a folder through eM Client to archive some mails. I did not create the folder through the webmail first though. After trying to move the mails to the newly created folder I received the following messages:
[IMAP] Unable to upload message “[subject of mail]” to folder “[foldername]”. ([SERVERBUG] BUG: Unknown internal error)
This is really annoying. 30-40 of these errors are shown each time I start eM Client. Do you have any idea of how to fix this without deleting all of them?
I have tried moving them back to the inbox folder, but then the foldername just changes to inbox, so it seems like the mails are corrupt or something.
