Simple question I'm sure many have the answer to.  For some reason I can't find a simple answer.

Is outlook anywhere required to be enabled on Exchange 2007 in a coexistence scenario with Exchange 2013? We have no External Outlook Anywhere cl

Hi,

From your description, I would like to clarify the following things:

1. Outlook 2007 or higher is required for an Outlook Anywhere connection to Exchange 2013, even if the target mailbox is still on Exchange 2007.

2. In a coexistence scenario that still has 2007 Client Access Servers, you need to enable Outlook Anywhere on each legacy Client Access Server.

For more information, here is an article for your reference.

Hope this can be helpful to you.
