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.

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

Users are reaching their Exchange 2010 mailbox quota and archiving. However outlook still reports them as using the same mailbox size . <br />
<br />
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 <br />
reported in outlook - Have tried switching from cached to non-cached mode - still no change.<br />

Thank you.
