How should i configure Outlook Anywere URL's in exc2010 -2013 coxistance?
should i put the same url's on both exchnage servers?
i have a situation where dns record mail.contoso.com is poniting to ex2010 CAS NLB, and all the clients are still on the ex2010 server. i also have two exch2013 cas in round robin configuratiog which dns name is mail2k13.contoso.com.
Shoud i change DNS record mail.contoso.com to point to ex2013 cas servers or should i do it after migration?
