I have a client with new installation of exchange 2013. Mail flow is working but there are some issues with outlook connecting, current users have a password prompt that wont accept their credentials and autodiscover for new users resolves their names but then also promts for passwords and never accepts them.
What I know and have read about this seems to stem from the fact that the client has a disjoined domain. here is what they have, they are Johannesburg (JHB)
domain name = domain.local
DNS = domain.local and domain.co.za
NetBIOS = domainJHB
Their external mail address is mail.domain.co.za
I have set the outlook anywhere to user NTLM, outlook has been updated to the supported service packs for exchange 2013 ie outlook 2010 with SP2.
I have tried some things in dns, such as remove the autodiscover.domain.local and created a SRV record to point to autodiscover.doamin.co.za. Thus far the only way I have managed to get outlook online is to do a manual setup and make sure outlook anywhere is set up.
any advise would be appreciated.
