How to resolve blank screen issue Exchange 2010 SP1 rollup 3/4

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 Exchange Administrative powershell and “Run As Administrator”

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.
