Select ONLY “Expunge deleted messages” and nothing else, then set the value to purge every 1 days.Then finally choose to purge all folders. Please navigate to the admin interface, select a domain under “Domains and Users” and select the “Purge settings”. Failure to enable this will mean that your mail items will never purge. You must enable the scheduling of the timed event which is primarily responsible for triggering the purge execution. Please ensure that you stop and start the IMAP service each time a change is made here. Any mailboxes that are less than 1GB will be purged during normal operation. So, if you set the value you be 1000000 (KB), any messages marked for deletion on mailboxes over the size of 1GB will be purged out of hours. This is the original mailbox file size before deleted items are taken into account. >0 – defer purge if mailbox folder size (in KB) is greater than the value you set.0 – never defer purge (default setting).

The variable is MaxFolderPurgeSize and its values are: This change can only be made via the Variables at either the domain or system level. It is merely perceived to be deleted by the end user. This, however, does not mean that the message will have been physically deleted from the mailbox as the whole point of this feature is that this is performed automatically, out of hours. With this enabled, when a user deletes a message from a large mailbox it will either disappear from your mail folder or Outlook will strike a line through the deleted item. In Version 14.01, build 3539, Gordano introduced the ability to optionally defer the purge of a mailbox so that this operation is executed behind the scenes out of work hours. This will naturally take some time for a large sized folders and can be severely exaggerated by other factors including a heavily fragmented disk and slow read/write access. The server-side operation that manifests as Outlook being unresponsive, is the entire mailbox, minus the message/s you have deleted, needing to be written out to disk and then reassembled as the new, updated mailbox. The only time you should ever see such a delay is if you are expunging a message from a mailbox that is particularly large in size.

How can I improve this experience for my users? Answer Although the message does eventually delete, it can be several minutes before Outlook becomes responsive once again. Some of my users occasionally complain that Outlook hangs when they delete a message from one of their larger mailboxes.
