delete folders in Deleted Items

[#1]

I'm using PlusNet Webmail, and after clearing out many folders on my desktop I find they've been sent to the Webmail app online and appear under "Deleted Items".

I can empty each subfolder by right-clicking and selecting "Empty" but this is laborious and the folders remain. Is there any way to delete the folders? I've tried every combination of Shift, Ctrl and Del I can think of, but they don't work. Thanks.

Culling mailbox contents

If you need to clean out your mailbox, may be because it is over quota, then as well as tidying up the inbox, you need to also look at the SENT ITEMS folder and then afterwards clear out the TRASH folder. However some times webmail performance can make this process very tedious, particularly if the delete action (actually a move to the trash folder) fails.

If you primarily want to delete emails, you can mitigate delete performance issues by doing an "immediate" delete (rather than a move to trash for deletion later) by holding down the SHIFT key when pressing the DEL key. This works in both webmail and most PC based email clients. WARNING SHIFT+DEL is not recoverable so be certain absolutely, that you do not need the email before pressing the buttons!

Alternatively, in webmail (Round Cube) Settings -> Server Settings there are some options worth exploring controlling how deletes are performed...

1. Flag the message for deletion instead of delete
2. If moving messages to "Deleted Items" fails, permanently delete them
3. Compact Inbox on logout

Setting these options and using them together will avoid the over heads of moving items to the trash folder when you wish to delete them. They will simply be greyed out and remain in the inbox list. After logging out of webmail, they will then be removed from the mailbox.

Whilst this might be highly proficient, it needs to be used with care, for when they are gone, they are gone. Note also that Plusnet house-keeping clears out the trash folder weekly.
