To delete mail for a space, you require 'Remove Mail' permission which is assigned by a space administrator from the Space Administration screens. See Space Permissions or contact a space administrator for more information.
Only a space administrator can delete all email messages for the space simultaneously.
To delete mail for a space,
Go to the 'Browse Space' view.
Go to the 'Browse Space' view. There are two ways to browse a space:
Go to a page in the space and select the option you want from the 'Browse' menu. The corresponding tab of the 'Browse Space' view will open.
Or click the icon next to the space name on the Dashboard. The 'Pages' tab of the 'Browse Space' view will open.
Go to the 'Mail' tab. A list of messages in the space is displayed in reverse chronological order.
Delete an individual email by clicking the trash icon beside it.
If you are a space administrator, you can delete all email messages within a space simultaneously by clicking on the 'Delete All' link at the top of the mail view. Deleted mail is stored under 'Trash' and can be restored by a space administrator from the 'Space Admin' tab.
Email messages deleted using the 'Delete All' option cannot be restored.
