Hi, We have done Exchange 2007 SP3 patching recently however after patching OWA users are unable to login (through RSA token authentication) Any known issues / patched causing this problem?

please refer to http://support.citrix.com/article/CTX126090 Dhruv

we are using RSA token authentication for external users which is not happening after patching Also for many users continuos username and password are observed

One more issue is there in Exchnage 2007 SP3. If you are using VSS backup with CCR then you may encounter issue of log purging after backup. To resolve this issue you must install RU1 or RU2 of Exchage 2007 SP3. Hope this info will help you !Anil

The only I have heard is OWA not working after going to Exchange 2007 SP3. I would highly suggest testing in a lab environment prior to your installation.

Quote: “many users continuos username and password are observed” The login window keeps asking for the credential (Username and Password) after you have entered them already, right? Please check if there’s any error event in the application log on the CAS server after reproduced the issue Please check if there’s any related trace in the IIS log on the CAS server after reproduced the issue Please increase the diagnostic logging level of the OWA related components on the CAS server Diagnostic Logging of Exchange Processes Resources: “Known Issues” section in Release Notes for Exchange Server 2007 SP3 IIS and File System Settings for Outlook Web Access How to Configure RSA SecurID for Outlook Web AccessPlease remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.
