We have a customer who has a public folder which is 96GB but only holds about 300MB of data. We have dismounted the public folder and run ESEUTIL a number of times but only managed to free up a few GB's.
We tried to create a new public folder but were unable to as it was saying one already exists. We copied the contents of the public folder out into a mailbox and tried to delete the public folder but were unable to as it said mailbox database is currently using it as the default public folder database. I have tried going into ADSI Edit as detailed here - http://exchangeserverpro.com/remove-default-public-folder-database-exchange-mailbox-database/
but did not work.
The server is Windows SBS 2011 Standard running Exchange 2010 14.03.0123.003.
What is the recommended way to delete and re-create a public folder in Exchange 2010?
