I'm using the form since Sales does not answer the phone, e-mails or the 'Contact Sales' form.
My client purchased the "Zimbra Starter Edition for 15 Professional Mailbox pack (perpetual license, no support, no Archiving & Discovery, Zimbra Mobile included)" within the last year.
Now they have reached the 15 user limit and would like to purchase more license and upgrade to "Standard 25 user, Premium Support with Perpetual license".
SALES, please answer this simple licensing question, answer the phone and help us out.
Have a good day.
