Recover Exchange mailbox

Exchange 2010 mailbox
I have a user that needs his deleted items recovered
Here is what happened:
1. he exported to a .PST file his whole mailbox
This did not export all of his inbox or sent items but he did not notice, it only exported this months emails
2. he also went into recover "recover Deleted items" in his 2013 Outlook and purged all deleted items

On my Exchange I do not have any Exchange brick level backups, I run Acronis 11.5 and backup the whole drive where Exchange is located
D:\Program Files\Microsoft\Exchange Server

Questions
1. is there a way to recover this mailbox deleted items?
2. Any recommendations on mailbox backup s.w. I have 50 users

thanks

Hi jsarinana,
Deleted items are retained within the dumpster till the deleted item retention period. By default it is 30 days. Please check your mailboxdatabase properties.

This is the command. This  will copy dumpster items of Joe to TempMailbox's "Joemail" folder..
Search-Mailbox -Identity "Joe" -SearchDumpsterOnly -TargetMailbox "TempMailbox" -TargetFolder "Joemail" -LogLevel Full

Open in new window


This is the command to assign permission
Get-ManagementRoleAssignment
Add-RoleGroupMember -Identity "Discovery Management" -Member Your.Username

Open in new window

Please check the permission
Get-RoleGroupMember -Identity "Discovery Management"

Open in new window


Maybe you have to log off and log back in for the last one to take affect (Get-RoleGroupMember -Identity "Discovery Management").
