Hi,
Can you delete the folder if we log onto the webmail interface of your email account?
Besides, we may try to unsubscribe to the IMAP folder and then try deleting it to see the result. To do this, please follow:
1. Right-click on the email address and choose the IMAP Folders command. The "IMAP Folders" window opens.
Click Query.
2. Select the desired folder then click Unsubscribe. An icon appears next to each subscribed folder.
3. Repeat for any additional folders, as desired.
4. Click OK to close the window.
Please let us know the result.
Regards,
Steve Fan
