Hello support team ,
We are planning to deploy Exchange 2013 "Exchange 2010/2013 Coexistence"
Just wondering Will there be any disruption of our internal/external email delivery for the OWA Outlook 2010 user access during Exc2013 installation and config ?
We utilize OWA internal / external access and Outlook anywhere has been enabled on exchange 2010.
I just want to make sure our internal/external email on the Exchange 2010 server works, until Exchange 2013 is fully tested ,configured and all user mailboxes have been migrated across.
I understand that Exchange 2010/2013 Coexistence will need to point all Clients access to the Exc2013 CAS server.
Thank you
