Emails won't open when in the yahoo mail inbox

Posted on 2013-01-03
Last Modified: 2013-01-13
Our school staff was able to access their yahoo mail in early December.  Now they are coming back from Christmas break and while they get into their Yahoo email account, when they try to open mail it gives them a blank screen.  We are running Windows XP, and we have tried IE8, Chrome and Firefox, all with the same results.  We have disabled the Trend anitvirus and still get same results.  We have cleared Internet Temp files to no avail.  I see that there was a history of this, but it dates back to 2008 and the suggested correction doesn't match current versions.  Please help?   Thank you,  Joni

Are you using a web traffic filter?  I have seen this issue before where a traffic filter was incorrectly categorizing some webmail servers and blocking access, but showing a blank page. Whitelist * if you're struggling to troubleshoot

Thank you, I will be out of my office Friday in meetings all day, but will give this a go on Monday.  I did whitelist within our mail filter but not our web filter.  I will accept solution if it works Monday.  Have a great weekend and I'll check back with you on Monday.

Hi, our fix was to adjust the ASA configuration and to allow longurl-truncate.

Thanks for the help!

The fix was specific to our filter appliance, but the white listing should have worked.
