The connection is unavailable

Hi there,

I have just installed a new Exchange environment and i'm testing all the connectivity.

Following things are working:
Incoming and outgoing mail
Email on android
Email on apple
Webmail (owa)

But i'm running in one issue i had before which i'm not able to solve.
Outlook still can't connect.

I create a email profile, set the outlook anywhere settings and press apply.
Then i enter my mailserver adress and my username.
After that it takes a while and gives me a credential menu where i fill in my username and password.

But after that it keeps loading, and says "The connection to Microsoft Exchange is unavailable. Outlook must be online or connect to complete this action"
Port 443 and Port 80 are forwarded too this environment, and all the "Test Outlook Connectivity" tests are turning out all Green.

EDIT:
My Setup:

All Server 2012 R2 machines
2x DC
2x Exchange 2013 CU9 (in DAG formation)

Internal and External URL's are https://domain.email/.....
Internal DNS has 2 records of domain.email to the internal IP of the two CAS Servers

I Also have a certificate which contains:
autodiscover.domain.email
domain.email
www.domain.email

Anyone who can help me to solve this problem?

Kind regards,
Justin

if your internal outlook is working , you can access OWA without any issues and test connectivity is green, it should work from outside as well. check from different machines from outside. configure new outlook profile

I have already tried in on 3 different locations outside of our network.
Even after trying 2/3 outlook profiles it still does not work.

It's a mystery, but i can't find the issue

I feel really dumb now.

Someone just told me, that i have to use the autodetect function which you get right after typing a profile name instead of doing it manually. This is not supported in Exchange/Outlook 2013
And now it works!

Thanks for the help so far
