We are in the middle of mailbox migration between Ex2007 to Ex2013 so now we have both Exchange server's present. It appeard that users cannot set OOF messages when they are connected outside of the company. Inside company network and through OWA they can do it without any erros, but externally they're receiving "Your automatic reply settings cannot be displayed..."
Before the migration we didn't had autodiscover entry, and everything worked well, so what happened that now we have lost access to set OOF ?
when I type https://webmail.xxx.com/ews/exchange.asmx I'm receiving note that "You have created a service." and this stands for Exchange 2013 url . When I type https://legacy.xxx.com/ews/exchange.asmx and enter credential I am receiving also xml page so I assume that's correct ?.
On both Ex2013 and Ex2007 for Ews were updated in the following way:
Ex CAS 2007 internal and external URL points to https://legacy.xxx.com/ews/exchange.asmx
Ex CAS 2013 internl and external URL points to https://webmail.xxx.com/ews/exchange.asmx
