Exception on delete items in public folders

I have deleted some items in a public folder and get the following error:

23:23:39 {mail-removed} [Exchange Web Services]  Verschieben von Elementen aus Ordner ‘Public Folders/!Support/’ in Ordner ‘Public Folders/Gelöschte Elemente/’

After a “repair” of the folders the items were gone from the “trash” and appear in the original folder.

Also you can send us logs, to turn on logging go to Menu>Tools>Settings>Advanced>tick EWS logging and try to replicate this issue, then you can send logs to cooper@emclient.com
