I'm in the process of migrating exchange 2003 to 2010 to 2013

Our trial period is going to expire soon and we are having installation issues with Exchange 2013 requiring DNS settings to use Secure Only updates however it is currently set to None and Exchange 2013 will not work with this setting.

Can we extend the original 120 days trial?

Having said that, I can share with you that Exchange will continue to work after the trial period. You'll just be nagged a lot.

Hi Devin,

Almost all of the Microsoft CALS are based on an honor system (until you get audited). No loss of functionality will occur when the Trial Edition expires, so you can maintain lab, demo, training, and other non-production environments beyond 120 days without having to reinstall the Trial Edition of Exchange 2013

As Ed mentioned, the Exchange Admin Center (EAC) will start to show reminders that you need to enter a product key to license the server.

If you want Trial only, do a fresh re-install to avoid any legal trouble.
