Hi,
I've upgrade two of my customers to Exchange 2013.
On of them was coming from 2007, and the other was already running 2010.
Migration from both of the servers went good.
However with the customer which upgraded from 2010 to 2013 i'm experiencing strange OWA behavior:
When I login to OWA on https://owa.contoso.com/owa, and input my credentials and click sign in: I receive this error:
The page you're looking for couldn't be found on the server.
X-FEServer: JVBMAIL01 Date: 11-6-2014 11:54:48
Fewer details..
-> Refresh the page
In the addressbar, the following URL is displayed: https://owa.contoso.com/owa/auth/errorFE.aspx?httpCode=404
But... when I click: "Refresh the page" of just hit F5, the login proceeds, and my OWA is displayed and working fine.
This behavior only happens with my customer which was upgraded from 2010 to 2013.
The customer which i've upgraded from 2007 to 2013 doesn't experience this problem.
I've matched the IIS settings and redirect/ssl options on both servers. They are the same.
I've tried other users and i've experienced that on one user, the error message didn't appear.
When I try to delete the Exchange atributes from the user, (after exporting the mail to a PST file) and re-add the Exchange attributes, the message is gone. This isn't a solotuion however, since i've got 166 users, and about 150 of them, get the error message.
New users don't get the error.
Anybody got any clues?
