Hello,I have connected a disconnected mailbox to my admin-user account and retrieved all the emails I needed.After few weeks, I need to connect another disconnected mailbox to my same admin-user account but I can not find it in the list of user available.Do I need to do something to free my admin account and being able to re-use it again to connect disconnected mailbox?Thanks to all in advance for you useful help!

You cannot have two mail boxes for single account. So first you need to disconnect the first mail box from the account and then reconnect the second mail box.How ever you dont need to attach a Admin account for retriving the email. You can create normal domain user, connect the mail box in question and can retireve the email.Raj

How do I disconnect the first mail box from the account ?

Hi, You can use Disable-Mailbox command to disconnect amailboxuser from its mailbox like this: Disable-Mailbox UserEmailID Laeeq Qazi|Snr Software Engineer(Exchange + Sharepoint + BES + DynamicsCRM) www.HostingController.com

Start the Exchange Management Console. In the console tree, expand Recipient Configuration, and then click Mailbox. In the result pane, select the mailbox you want to remove. In the action pane, under the name of the mailbox, click Remove. A warning appears asking, Are you sure you want to remove 'mailbox name'? Click Yes to remove the mailbox. To use the Exchange Management Shell to remove a mailbox To disconnect the mailbox for user "john" from John's user account and also delete the user account, run the following command: Remove-Mailbox -Identity domain\user Raj

Hi, Remove-Mailbox will delete the associated user from AD . Is OP not asking about disconnecting the mailbox instead of removing the user and disconnecting the mailbox? Regards, Laeeq Qazi|Snr Software Engineer(Exchange + Sharepoint + BES + DynamicsCRM) www.HostingController.com
