I have a client using Outlook 2013 in an Exchange 2007 environment. His mailbox is almost full (338 Mb of 2Gb remain)and would like to archive anything older than 1/1/2013 in his mailbox (including subfolders). We are running Outlook in Cached Exchange Mode with the slider set to "All". When we attempt to archive the mailbox it just creates a shell of all the folders in his mailbox but no emails are archived. Archive this folder and all subfoders is selected, I select the top level of his mailbox, enter the date above, check "Include items with "Do not Autoarchive", click OK. I look in his mailbox and there are emails all the way back to 2003 and I don't understand why they aren't archived. Any and all assistance is greatly appreciated.
It puts the email in to a PST file. As far as I am concerned, there is no difference between storing your email in a PST file and deleting it. It will be lost eventually, just deleting it means you know it has gone.
If you have a business need to store that email, then you need to find an alternative. One way would be to simply create an additional account for the user, grant them full mailbox rights and add the mail in to the that second account. That keeps the email in Exchange, where it can be backed up correctly.
Although a 2gb account isn't that large. I am currently working with a client where the average size is 5gb. You could just as easily increase the limit.
