No Create Mailbox Option for user in AD

Environment:
Windows 2000 Server, Exchange 2000.

I have a few users that at one point had their mailboxes deleted. Now, when right mouse clicking on their user account and selecting “exchange tasks”, I dont get the option to create a mailbox for them. Only enable IM and remove exchange attributes are listed. There is no choice to create, delete, or move a mailbox.

The mailboxes that I am trying to recreate were deleted months ago. Also, I do have all Exchange task options for most users.

Any ideas?

Thanks.
