I migrated all functions and mailboxes to a new Exchange 2013 server with all updates.

I further installed a public SSL certificate. Access seemed fine to all mailboxes.

I clicked on the gear button for all options and some of them return with a page 500 error:

Here are the ones not working:

Set automatic replies:
https://my server/ecp/?rfr=owa&owaparam=modurl%3D0&p=organize/AutomaticReplies.slab

Manage apps:
https://myserver/ecp/?rfr=owa&owaparam=modurl%3D0&p=installed

Change password:
https://myserver/ecp/?rfr=owa&owaparam=modurl%3D0&p=PersonalSettings/Password.aspx

Options:
https://myserver/ecp/?rfr=owa&owaparam=modurl%3D0&p=account

They seem to go to the virtual directory ecp. I checked the virtual directory settings and the External is set correctly to the outside URL (https://myserver/ecp) and the internal is set to an internal URL (https://servername/ecp). Not sure if they both should have the external settings.

Not sure what is going on. I did notice when I setup the SSL cert I choose domains pointing to my external URL of m1.myserver.domain.  I checked the subject alternate domains of the certificate and the only one there is the m1.myserver.domain. The autodiscovery.myserver.com is not listed. Not sure if this is an impact. Also the certificate is setup to use   IMAP, POP, IIS, SMTP. Please advise.

The CAS and the mailbox server on are on the same server.

the options are there when I log on with the account on other machines. Therefore its an issue with the one machine. Everything is available.

Hi,

From your description, when you use the same account to access EAC on other computers, EAC works well. Then EAC virtual directory and the permission are ok. The issue is related to browser. I recommend you use IE browser to check the result.

Hope this can be helpful to you.
