Remove existing mailbox and re-create in Exchange 2010/SBS2011

Hi,
 
 I have an existing exchange mailbox that is corrupted and I need to re-create this mailbox from the scratch.
 Can you give me a set of steps to remove ONLY exchange mailbox from the user (I like to keep this user in active directory) and re-create a new mailbox for this user?
  I will export user's email from Outlook into a PST file and import from PST after new mailbox is created.

Thanks.

Use the EMC to create a mailbox for an existing user
You need to be assigned permissions before you can perform this procedure.
In the console tree, navigate to Recipient Configuration.
In the action pane, click New Mailbox.
On the Introduction page, click User Mailbox, and then click Next.
On the User Type page, click Existing user, and then click Add.
In Select User, select the user for whom you want to create a mailbox, and then click OK.
Click Next.
On the Mailbox Settings page, complete the following fields:

Alias   Use this box to type the alias for the user mailbox. If the user logon name contains any characters that aren't valid for the alias field, they will be replaced by underscore characters (_). The alias can't exceed 64 characters and must be unique in the forest. If you're creating mailboxes for multiple existing users, this box will be unavailable and will display the following message: An alias will be automatically generated for each new mailbox.
noteNote:
You can’t use an apostrophe (') or a quotation mark (") in the alias because these characters aren’t supported in email addresses. Although you might not receive an error if you create a mailbox using unsupported characters, these characters can cause problems later. For example, users that have been assigned access permissions to a mailbox that was created using an unsupported character may experience problems or unexpected behavior.
Specify the mailbox database rather than using a database automatically selected   Select this check box to specify a mailbox database instead of allowing Exchange to select a database for you. Click Browse to open the Select Mailbox Database dialog box. This dialog box lists all the mailbox databases in your Exchange organization. By default, the mailbox databases are sorted by name. You can also click the title of the corresponding column to sort the databases by server name. Select the mailbox database you want to use, and then click OK. This is an optional field.
Managed folder mailbox policy   Select this check box to specify a managed folder mailbox policy for the mailbox. A managed folder mailbox policy is a logical grouping of managed folders. When a managed folder mailbox policy is applied to a user’s mailbox, all the managed folders linked to the policy are deployed in a single operation, thereby making the deployment of messaging records management (MRM) easier. To learn more, see Understanding Managed Folders.
Click Browse to open the Select Managed Folder Mailbox Policy dialog box. Use this dialog box to select the managed folder mailbox policy to be associated with this mailbox. This is an optional field.

@Tom
Thanks for the detailed step to create new mailbox.
How do I go about deleting this existing mailbox? Last time when I removed it from Exchange Mgmt Console, I ended up deleting the user from Active Directory and I don't want that.

Don't need to delete till you will be sure all is working OK.
Just go and disable mailbox

OK.
(1) I am exporting Outlook email into PST on user's  workstation PC.
(2) Once PST is created, I will disable existing user mailbox from Exchange Management Console.
(3) I will create a new mailbox and select existing user in Setup Wizard.
(4) Once a new mailbox is created, I will create a new Outlook profile in user's workstation PC and open Outlook.
(5) I will import from PST.

Yes, or you can logon to user mailbox via OWA (new one) to make sure is working before you'll run Outlook.

When I export into and import from PST, is Outlook Autocomplete list (Stream_Autocomplete_0_F4351E026CE8F142B07783036018B2F3.dat) supposed to be restored?
0
Tom CieslikIT EngineerCommented:
Yes, since Exchange 2010 and outlook 2010 Autocomplete list ins placed as hidden email in user mailbox.

Last time when I did the same, it did not come with it. I had to use autocomplete file associated with old outlook profile and rename it to new autocomplete file tied to new profile. I thought that is what happens when exchange mailbox is removed and recreated. We will see how it goes this time.

I will report back on the morning.

Because probably user had Office 2007 or they was connected to Exchange 2007

Outlook 2007 used a separate file (the .n2k file...or maybe it was .nk2...I forget) that you could copy and rename but, as Tom points out, the so-called "nickname" file went away with Outlook 2010 and now exists as a hidden message in the user's mailbox.

I had to manually handle autocomplete list.
