In Contacts I have some duplicate folders and it seems impossible to delete or rename them

Unable to delete or rename folders in contacts

If you are referring to Local Folders > Contacts, this is a system folder and cannot be deleted.

If that is not what you meant, can you maybe post a screen shot indicating which folders you want to delete, and who your contacts provider is.

Unfortunately you cannot delete or rename a Google System folder.

The only way to remove this error from re-appearing is to remove the Gmail account from eM Client, then add it again. Then try and avoid changing it again. :wink:
