I have a user who is receiving an error message using Outlook Web Access in Exchange 2007. She says it happens randomly (Since I'm not around her all the time, I can't discredit or verify this.) but this time it was when she was replying to an Email. A dialog box pops up stating that OWA has encountered an error. When I click to view the report I get the following: <!-- /* Font Definitions */ @font-face {font-family:"Cambria Math"; panose-1:2 4 5 3 5 4 6 3 2 4; mso-font-charset:1; mso-generic-font-family:roman; mso-font-format:other; mso-font-pitch:variable; mso-font-signature:0 0 0 0 0 0;} @font-face {font-family:Calibri; panose-1:2 15 5 2 2 2 4 3 2 4; mso-font-charset:0; mso-generic-font-family:swiss; mso-font-pitch:variable; mso-font-signature:-1610611985 1073750139 0 0 159 0;} @font-face {font-family:"Book Antiqua"; panose-1:2 4 6 2 5 3 5 3 3 4; mso-font-charset:0; mso-generic-font-family:roman; mso-font-pitch:variable; mso-font-signature:647 0 0 0 159 0;} /* Style Definitions */ p.MsoNormal, li.MsoNormal, div.MsoNormal {mso-style-unhide:no; mso-style-qformat:yes; mso-style-parent:""; margin:0in; margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:12.0pt; font-family:"Times New Roman","serif"; mso-fareast-font-family:Calibri; mso-fareast-theme-font:minor-latin;} a:link, span.MsoHyperlink {mso-style-noshow:yes; mso-style-priority:99; color:blue; text-decoration:underline; text-underline:single;} a:visited, span.MsoHyperlinkFollowed {mso-style-noshow:yes; mso-style-priority:99; color:purple; mso-themecolor:followedhyperlink; text-decoration:underline; text-underline:single;} .MsoChpDefault {mso-style-type:export-only; mso-default-props:yes; font-size:10.0pt; mso-ansi-font-size:10.0pt; mso-bidi-font-size:10.0pt;} @page Section1 {size:8.5in 11.0in; margin:1.0in 1.0in 1.0in 1.0in; mso-header-margin:.5in; mso-footer-margin:.5in; mso-paper-source:0;} div.Section1 {page:Section1;} --> Client Information ------------------ User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 2.0.50727; .NET CLR 3.0.04506.30; .NET CLR 1.1.4322; .NET CLR 3.0.04506.648; InfoPath.2; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729) CPU Class: x86 Platform: Win32 System Language: en-us User Language: en-us CookieEnabled: true Mime Types: Exception Details ----------------- Date: Tue Dec 8 08:35:12 EST 2009 Message: 'parentElement' is null or not an object Url: https://exchange.mvsd.net/owa/ Line: 1 Call Stack ---------- anonymous() ----------------------- function anonymous() { return (parentElement.offsetWidth - 31) } ----------------------- Dump Event ---------- recordset = null type = error fromElement = null toElement = null altLeft = false keyCode = 0 repeat = false reason = 0 data = behaviorCookie = 0 source = null contentOverflow = false behaviorPart = 0 url = dataTransfer = null ctrlKey = false shiftLeft = false dataFld = returnValue = undefined qualifier = wheelDelta = 0 bookmarks = null button = 0 srcFilter = null nextPage = cancelBubble = false x = 0 y = 0 srcElement = null screenX = 462 screenY = 379 srcUrn = origin = boundElements = [object] clientX = 275 clientY = 189 propertyName = shiftKey = false ctrlLeft = false offsetX = 0 offsetY = 0 altKey = false errorMessage = 'parentElement' is null or not an object errorUrl = https://exchange.mvsd.net/owa/ errorLine = 1 errorCharacter = 1 errorCode = 0 I am not sure what this means so any help that can be provided would greatly be appreciated.Matt Georgetti

Looks like Browser crashed. Is it IE or Mozilla??Raj

Raj, Thank you for the response. It is Internet Explorer 8.Matt Georgetti

Hi, First please try to go to IE-Tools-internet options-advanced-disable script debugging (other) & disable script debugging (Internet Explorer),please ensure that you have tick these two items. Then please verify if you have install S/MIME plug-in from Add/Remove.It will be listed under Microsoft Outlook Web Access S/MIME (2007)".If yes, then please uninstall it. Also as a workaround, please try to add the TabProcGrowth key to 0. After adding this key you should only see 1 IE process in the task manager instead of 2+ processes. This will be like the behaviors of IE 6/7 that run only under a single process. HKCU\Software\Microsoft\Internet Explorer\Main. Besides, please apply SP2 with rollup 1 for Exchange Server 2007. Regards, Xiu

Xiu, I will give those solutions a try. Thank you.Matt Georgetti
