We are running Exchange 2007 SP3 Rollup 6 and Outlook 2010

I am trying to convert a Linked mailbox to a regular mailbox using the Set-User command with argument -LinkedMasterAccount $null but it just does not work. I have tried different combinations but they all error out.

Please help.

This example converts the shared mailbox ConfRoom11LARGE to a room mailbox.

Set-Mailbox ConfRoom11LARGE -Type Room
You can use the following values for the Type parameter:

Regular
Room
Equipment
Shared

you may need to disable the mailbox and connect it again to connect as User Mailbox.

Thanks for the tip. However, disabling the mailbox will remove all permissions on the mailbox, such as Send As, Full Access, folder permissions, and calendar delegation. Is there another way?

Commented:
There is no other way as the mailbox is assigned to a different user. The user you will want to make it a mailbox for will still need the permissions manually assigned when the mailbox is reconnected.

Sorry for the delay in returning, a couple of work emergiencies took all my attention. With regard to the answers, although they not really resolve my problem,  I am accepting JBackes' answer as a reasonable solution.
