Hello. I am trying to figure out how I can go about doing a restore of emails from SourceOne to mailboxes.  First, we are using Sourceone 6.6.  We had about a 3 day period where we lost emails in Exchange but they are in SourceOne.  Users need these back but right now everyone is using IE 11 and SourceOne 6.6 doesn't work with IE11.  So I can do a search from the server and do a restore for each user but we have about 600 users.  These emails did not make it to shortcut time yet.  So they are just archived.  The problem was our two Exchange servers were not syncing for 3 days and then the log drive on the active failed.  So 3 days of emails are not in Exchange but they did get journaled.  So is there a easy way to select all emails from those 3 days and do a restore back to original location or do I have to do each user at a time?  We are under a time crunch.

Thanks
