What I like to do.

erroremails
- backup

Find emails in a folder by a search value (folder erroremails)
If I found it, i read some values out I needed
Now I save the email in a backup folder (subfolder of the search folder erroremails.backup)
Delete emails from erroremails folder

How can I find the subfolder of my folder find
by the SelectFolder(Imap4Folder)

If I use the Imap4Folder for further operations I get no subfolders.

I hope you understand what I mean

I can do it also by procedure imap4folders and subfolders but if I have the Imap4folder of the folder, I like to go the short way.

Hi, if you want to get the sub-folders under the erroremails, you have to use MailClient.Imap4Folders property to get all folders and find the erroremails folder at first.

You can not construct the erroremails folder directly
