Freeing up mailbox data after archiving

Users are reaching their Exchange 2010 mailbox quota and archiving. However outlook still reports them as using the same mailbox size .

Read an article that need to do an offline defrag (which I wish to avoid) - or moving mailbox to another database can cause defrag to happen. Have tried this and still no change
reported in outlook - Have tried switching from cached to non-cached mode - still no change.


Thank you.

You could compact the local file too, that may help.

You could take a look at

https://blogs.technet.microsoft.com/rmilne/2013/08/20/how-to-check-database-white-space-in-exchange/

Check the white-space and go from there, also if they are archiving mail, it may take time for it to stub the email.

Mailbox size - it says you have reached quota - so users are archiving - but mailbox size is not going down . I read somewhere that moving the mailbox from one database to another causes exchange to report the correct size - but didnt work for me.

to check the actual mailbox size run the below cmdles in exchange shell:

Get-MailboxStatistics "username" | ft displayname, totalitemsize

This will show to the actual size of the user mailbox. outlook may be showing incorrectly because of cache, but it's also possible that even though the users are archiving they are not archiving enough mail data to make a difference. run the cmdlets to see the correct size despite what outlook shows. if its the same then the user just aren't archiving enough to make a difference. remember emails are generally pretty small so it takes alot to make it shrink at times.

Thank you - running that cmdlet shows exchange still has their mailboxes as the same size as outlook is reporting.
