sorry . this is not help on this case . bit advance level of feedback need

You need to have a ClientAccessArray for each site in AD.  You can then change DNS in each site to point to its local owa array. Once you do that just go into IIS on each array and set it to the correct certificate for use with the local address or load balanced address.
So if you have in site B1 the array may be arrayb1.org then point it to the DAG or mailbox server it should use. the same for B2, B3 and B4.
Once you have 4 arrays, you can then trick local DNS to think that owa.org is the local address for each AD site. In your case, any array will access the DAG or mailbox servers but from each location.
A bit tricky, but it can be done.

without that option . best option we have to access the mail server in  headoffice via OWA .isn't it
some of the places we  have only 5 mail users except b4 got 20 users . all other users in Head office .
some are giving the option to create the DNS A record pointing to Head office DNS . primary dns zone to abc.com  from the branch network dns server (abc.local). so then users can used the outlook any ware ?

Yes that should be fine, as long as you assign unique addresses to each DNS entry and then bind a certificate for each site to IIS on the CAS server in question.
The smaller sites, can connect to head office and the larger sites will connect to their local CAS array.

Please correct me if I am wrong but, from the diagram, it seems you only have exchange in the head office.

If this is the case then adding a CAS in each site is useless it will only make you spend more money.

Your issue is that the sites are not configured to resolve abc.com domain correctly what you should do is

a. Go to the DNS server of each of Sites B3 and B4
b. Right click properties on the DNS server name -> forwarder
c. configure conditional forwarding to send all abc.com requests towards the DNS server in the head office

yes  Akhater .

 adding  Cas  in each site not worth . that option totly out . sites are not configired to resolve abc.com .
i need to do the conditional forwarders in the  B3 and B4 . somebody told me  separate zone for abc.com in the brach level . it seems to be not correct . that's why i didn't do that . i will try this conditional forwaders .

how about the workgrop dns . how can I setup  the same thing ? is it forwarders or anything else ?

you can configure conditional forwarding on any DNS server no matter if it is workgroup or for a domain as long as the clients points to it it would work

<< With akhater.
I dont think you can configure CAS arrays from branch since they dont have any exchange installation.

Also
Your outlook clients which are not joined to the domain will repeatedly prompt for passwords.

The way to get around that is this.

Please test this on a workgroup:
a) Configure DNS forwarding as per akhater's post above.
b) try to setup Outlook RPC/HTTPS to connect to exchange in HQ.
c) Work around the password prompt issue using the post in above link.

Please post back if you have questions.

i have the same issue .i will try all your method tommorow and see.
still i can go with the OWA access from the branch . isn't it

what do you mean by "i haev the same issue" ? what did you try to do ?

outlook password promt issue

I don't understand you got me lost can you now access OWA https://name.domain.com/owa?

a. Go to the DNS server of each of Sites B3 and B4
b. Right click properties on the DNS server name -> forwarder


c. All other domains and i can mention the ip address or do i have to create the new one called abc.com ?

Do we need any record on the DVS server level as i mentioned to you like mail.abc.com . but i need a new zone to do that . isn't it

create one called abc.com that's it

still i cant access that https://name.domain.com/owa? from the branch level . only https://ipaddress/owa
i am trying to do your conditional forwaders and see . for that i need to know there is a option All other domains and i can put my abc.com ip address  or new ----abc.com -----ipaddress

don't use "all other domians" create one called abc.com and forward it to the abc.com dns ip that's all you need

thank you

Akhater: conditional forwerders ok . now i can resoleve the name from the branch level .
now i am trying to do the outlook anyware setup for the same poeple . coz i think it will more flexible for them.

password promt issue ? sunnyc7 are sure this will work or any other alternate options  ?

Great cur, if you need more help just update this thread

i am testing this client side by login to the remote client computer as administrator and setting up the outlook anyware for test user . i hope no point of login to the remote PC as test user due to branch network in the separate AD. just i want to confirm by setps are correct on outlook anyware configuration.

Still i can't login to the exchnage server via outlook anware from the branch . asking password . I did the following settings. one of the link says 'S1' to enter as server ? what you mean my 's1' . shell i try this ?

following is the way i tried .

e) erase the Server name and type in the name of your DC /  global catalog server
there is no server name to erase . but i add new server entry with my GC server name with FQDN -dc1.abc.com and i have put the username as test . i have to enter the login name

f) leave the password blank and click OK

i am not testing administrator account . i am login to the remote client PC via remote windows session configuring as normal user account . i will try this and update you
thank you

good
