i am facing an odd issue since updating exchange 2013 to fix a comon hybrid configuraion error.

I cant access outlook web app from internal network. from outside however it jsut working fine. is there an issue with bindings?

my internal domain is .local and external is .com

Hi Riaz,

Thank you for your question.

Is there any error when we login on OWA?

Are the outlook anywhere and autodiscover  available in internal?

Are there any errors in event id? I suggest you post error to ibsexc@microsoft.com for our troubleshooting.

We could run the following command to check internal url:

Get-OWAVirtualDirectory | Select ExternalURL,Identity | FL

If the URL is wrong, we could refer to the following link configure internal URL for OWA:

Get-OWAVirtualDirectory -server <EXCHANGE SERVER NAME> | Set-ECPVirtualDirectory -InternalUrl https://mail.DOMAIN.local/owa  

If the issue persist, we could check certificate for OWA by the following link:

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

Best Regard,

Jim

Jim I messe with virtual directory links and now I can send email out to outside world but cant recieve emails from outside. as i mentioned my internal domain is mydomain.local and outside domain is mydomain.com.

the OWA is accessable from outside world by the live link which is webmail.mydomain.com but its not from inside with that live link. IT IS tho with local link.

trying to fix that I have messed up the virtual directory links and now cant recieve emails. all tests pass all green with exchange connectivity analyser SO I have no idea what the issue is.

Acctually the incoming emails issue is resolved as I had removed the internal FQDN from the cert i re downloaded the cert with FQDN as one of its sans and all the emails came throug all at once:)

however i sitll cant figure out why cant access OWA from inside network jim
