ve just installed Update Roll-up 7 for Exchange 2007 SP1, and afterwards the Outlook Web Access showed a blank page and there was a yellow exclamation mark in the bottom left corner, which stated “syntax error on line 6 of login.aspx”.
I first tried the solution Microsoft provided in this support forum thread, although it didnt work for me.
I had to re-create the OWA Virtual directory.
I accomplished this using these two PowerShell commands from the Exchange Management Shell:
Actually the Microsoft Exchange Team stated the following reminder in the blog post regarding Update Roll-up 7:
“And finally, from the installation perspective, a friendly reminder that the roll-up installer will overwrite any OWA script files if required to ensure proper operation of OWA. So if you have customized the logon.aspx page or other similar OWA pages, you will need to redo any customization after installation of the roll-up.”
My recommendation would be to backup the C:Program FilesMicrosoftExchange ServerClientAccessOWA folder before installing an Exchange 2007 Update Roll-up.
