Changing BESadmin maill address in connector

[crawlspace35]

Hi all,
Maybe a stupid question but here it goes.
Im trying to support multiple domains with a single BES, found something that might work: Bug 32836 – support multi-domains in blackberry connector

but hit a snag of sorts.

Is it possible to simply just change the email address of the bes admin in the existing outlook profile to a different one I created on zimbra or must I delete the profile and re-create it.

I ask because simply typing in a new address does nothing, click apply and no response, I have to cancel it.

The initial install was such a nightmare that I am reluctant to delete anything unless absolutely necessary.(lots of problems in the initial setup)

Thanks
