    Insufficient resources.
    Most likely insufficient memory, or perhaps a user/application
defined limit on the number of mailboxes.

Hi, All -

This question came up in a class last week and I could not think of a 
good answer.

14.3.1 New()
Mailboxes are created with the new() method.
...
The new() function returns the mailbox handle or, if the mailbox 
cannot be created, null. ...

Under what circumstances could creating a mailbox fail and return null?

Regards - Cliff
