Exchange 2013 SP1 - Error: Your request could not be completed

When trying to log into the ECP I get an:

Error

Your request could not be completed.  Please try again later.   

When I check the event viewer I get:

WebHost failed to process a request.
 Sender Information: System.ServiceModel.ServiceHostingEnvironment+HostingManager/6837052

I am trying to create a Send connector and it gets all the way through but then fails at Select Source Server.   There are no source servers listed.   Why does it not pick up itself?    

As for the error I think this is related to IIS permissions somehow and here is how i have the bindings set:

Default Web Site:

http   80  *

net.msmq   localhost

msmq.formatname localhost

net.tcp 808:*

net.pile )

https exssrv.cas.local 443 *    (With the SSL cert being the Microsoft Exchange built in one)

Exchange Back End 

 http exssrv.cas.local 81 192.168.1.5

http exssrv 80 *

net.pipe *

https  exssrv.cas.local 444 192.168.1.5  (Bound to Microsoft Exchange ssl)

I am connecting to the site internally from https://exssrv.cas.local/ecp

Thanks for any suggestions.. I think I am almost there on the install!   Hoping!

Hi ,

Thank you for your question.

This error was caused by the incorrect site binding, I will give a reference of my test Lab. We add two A records in DNS which the FQDN of CAS and Mailbox could resolve IP address.;

Default Web Site:

Exchange Back End:

Then IIS must be restarted.

If there are any questions regarding this issue, please be free to let me know. 

Best Regard,

Jim

I didnt create the A records though.. what do I have to do to get that in?

Hi HamzaMCSE,

If we have been accessed ECP, we could not create A record.

If there are any questions regarding this issue, please be free to let me know.  

Best Regard,

Jim
