Because I suspected an issue relative to Cas Proxy. I changed the owa Internal Url to have a correct FQDN who correspond to the certificate name. From the Server2 it try to open from IE the https://srvexc01.mrsaero.Loc/owa and it works. The contrary too. So the Cas proxy is working but I have still the same issue.

It try to remove all internal urls and external urls form both server owa site

Set-OwaVirtualDirectory -identity « SRVEXC02\owa (Default Web Site) » -externalurl $null
Set-OwaVirtualDirectory -identity « SRVEXC01\owa (Default Web Site) » -externalurl $null
Set-OwaVirtualDirectory -identity « SRVEXC02\owa (Default Web Site) » -internalurl $null
Set-OwaVirtualDirectory -identity « SRVEXC01\owa (Default Web Site) » -internalurl $null

And iisreset for all IIS Server

Well Same issue it is probably not linked to the URL on owa .

After searching. When I try to access from the srvexc02 to srvexc01 (Cas Proxy) I saw each time I try to logon this event on srvexc01

Event code: 3005

Event message: An unhandled exception has occurred.

I will try to delete the owa directory from srvexc01 and recreate it (Boring !!!)

 

[PS] C:\Windows\system32>Remove-OwaVirtualDirectory -Identity « srvexc01\owa (Default Web Site) »

Confirm

Are you sure you want to perform this action?

Outlook Web App virtual directory « srvexc01\owa (Default Web Site) » is being removed.

[Y] Yes [A] Yes to All [N] No [L] No to All [?] Help (default is « Y »): A

[PS] C:\Windows\system32>

 

[PS] C:\Windows\system32>New-OwaVirtualDirectory -WebSiteName « Default Web Site » -Server srvexc01
Name Server OwaVersion
—- —— ———-
owa (Default Web Site) SRVEXC01 Exchange2013

Put the authentication form on it

[PS] C:\Windows\system32>Set-OwaVirtualDirectory -FormsAuthentication $true -Identity « srvexc01\owa (Default Web Site) »
[PS] C:\Windows\system32>iisreset
Attempting stop…
Internet services successfully stopped
Attempting start…
Internet services successfully restarted
[PS] C:\Windows\system32>

After recreation I saw that in the event log : Grrrr


I decide to delete again the owa directory and clean the IIS Metabase

Removing the OWA on srvexc01 and installing iis resource kit / Checking with Adsiedit if the directrory is correctly deleted



Deleted correctly
Launching IIS Metabase


The OWA is correctly removed by the remove-virtualdirectory All seems correct!

OK IISReset and try to recreate the owa directory. Just creating the directory and saw that:


Reboot the server Srvech01

Repositioning this url

Set-OwaVirtualDirectory -identity « SRVEXC01\owa (Default Web Site) » -externalurl $null -internalurl https://srvexc01.mrsaero.loc/owa -FormsAuthentication $true
Set-ecpVirtualDirectory -identity « SRVEXC01\ecp (Default Web Site) » -internalurl https://srvexc01.mrsaero.loc/ecp

Set-OwaVirtualDirectory -identity « SRVEXC02\owa (Default Web Site) » -externalurl $null -internalurl https://srvexc02.mrsaero.loc/owa -FormsAuthentication $true
Set-ecpVirtualDirectory -identity « SRVEXC02\ecp (Default Web Site) » -internalurl https://srvexc02.mrsaero.loc/ecp

And it works ..why ? don’t ask me please
