We have a customer with a user mailbox that has become unresponsive due to its size. The mailbox is over 14GB. We found that an issue with his blackberry duplicating contacts over and over again - he now has over 750,000 contacts.
We have stopped the BB from syncing but now his mailbox is mostly unresponsive, and the contacts folder never displays at all.
We have logged the user on to a brand new PC and also tried from their terminal server to clean up the contacts but Outlook just hangs.
We need to remove all the duplicate contacts - is there an exchange command shell we can use from the server (SBS 2008) to remove his contacts folder as all attemps we have tried from the client side have been unsuccessful. We have tried Outlook in Cached and non-cahced mode, deleted and re-created the OST - all to no avail.
Any help appreciated.
