Re: 404 error when saving or opening attachment

I have fixed the problem. It seems that IIS 7.5 does not allow double escaping by default, which will cause 404 errors when saving attachments with a 'plus' sign in the filename.

Solution: Modify the 'requestFiltering' attribute and set it to 'allowDoubleEscaping=true'. You can do this by selecting the 'Default website' (if you created your own site for webaccess, select that one) and open the 'Configuration Editor' option. In the 'Configuration Editor' go to 'system.webServer/security/requestFiltering' and set the ''allowDoubleEscaping' value to true. I'm not sure if it's necessary, but I restarted the IIS, Tomcat, and Webaccess services.

After changing this option in IIS, I no longer experience problems with attachments that have a 'plus' in the filename. I hope it helps someone else with this problem.

We are on GroupWise 2012 SP2 running on Windows 2008 R2. Evidently, Novell has still not resolved this issue, as we just had a user email out an attachment containing a "-" as part of the attachment filename... and no one could open it through GW WebAccess. Everyone was getting the "404- File not found, etc." error when trying to click on the attachment link. The regular client could open it just fine.

Your workaround did the trick, though! Thank you for posting! Novell, please fix this ancient bug!

Re: 404 error when saving or opening attachment

Hi spaschall

As far as I am aware this is specifically an IIS issue and not a GroupWise issue. IIS will fail on any website that it is running if you try to access a document with a "-" or "+" etc, unless you have allowed double escaping.
