Today I found an issue which is pretty common if you search on the internet that the Outlook web Access shows a blank screen instead of the normal logon page.
“Blank OWA Screen after installation of Rollup 3 or 4 of exchange 2010 SP1”
[ note rollup 4 isn’t available for download anymore due bug some issues in the rollup ]
This issue could happend when you install a rollup 3 or higher.
You can solve this issue first to reinstall or install a new rollup version.
Go to the location where you downloaded the latest Rollup of Exchange 2010 SP1
Run the command “ii Exchange2010-KB2509910-x64-en.msp”
The setup wil start.
if the issue still exists after the installation. Than you should check the IIS settings.
Reinstall the IIS features using the following commands:
- Import-Module ServerManager
- Add-WindowsFeature NET-Framework,RSAT-ADDS,Web-Server,Web-Basic-Auth,Web-Windows-Auth,Web-Metabase,Web-Net-Ext,Web-Lgcy-Mgmt-Console,WAS-Process-Model,RSAT-Web-Server,Web-ISAPI-Ext,Web-Digest-Auth,Web-Dyn-Compression,NET-HTTP-Activation,RPC-Over-HTTP-Proxy -Restart
- Set-Service NetTcpPortSharing -StartupType Automatic
When you’ve done this you could check if you see the basic IIS 7.0 page. and than also they https://localhost/owa
If you see the page above. Outlook Web Access should be working fine again.
