exchange 2010 user unable to archive mail

Hi all,

I have a question in regards to a user unable to execute a correct archive of his user email that are stored on exchange 2010. The users for some time now starting in Outlook 2007. This has been a challenge for about 3 years. We want to archive up to 2 months. I have tried the following with no luck:

1.  Used older version of outlook to release email, outlook 2007, 2010, and current 2013.
2.  Tried the default 14 day waiting it out, exchange not recycling correctly.
3.  Used Regedit to archive according to delivered date not modified date
4. Moved mail data to another Mail Store, in same forest

No other user is experiencing this issue. Over the last 8 years his email seems to never decrease in size at all regardless of the time we archive. If we manually estimate his emails in 2 months and take in account calendars its total size approximately  4 GB of data, the server is telling us 16 GB of data.

Thanks all.

If it works for all users except that one, I would suspect an error with his mailbox (those mailboxes become corrupted sometimes).

The easiest fix will be to export all mailbox items to a PST file, delete the mailbox, create a new one and import back the information. The only issue, you could have what this approach is with the scheduled meetings – they might lose the connection with the meetings in the other users’ mailboxes, meaning the user will not be able to reschedule an existing meeting. You might also lose some corrupted items during the export process so be sure to compare the content (message count) of all folders before deleting the corrupted mailbox.
