Its been found that there is a situation when an Exchange Administrator deletes mailboxes from Exchange 2010 and later when try connect from EMC its not able find the AD user to get it connected.
In this scenario please follow below steps for connecting it. In this scenario I was deleting a mailbox going by the name ‘Bad User’.
- Login to server and open ADSIEDIT.
- Locate the user from ADSIEDIT tool and go to properties of user.
- Select the attribute ‘msExchRecipientTypeDetails’ and click on edit.
- Click on ‘Clear’ then on OK
- Make sure that the value changed to <not set> and click on OK
- Go to EMC and locate the deleted user.
- Right click and select connect
- Click on Next
- Click on Brows.. now you will be finding the user
- Fill ‘Alias’ and click on Next
- Click on Connect
- Click on Finish
