OWA – ‘gtLV’ is null or not an object

OWA – ‘gtLV’ is null or not an object

I was getting the “gtLV’ is null or not an object” message when I replied to an email using our Microsoft Online Hosted Exchange email account. Ironically enough, the problem would always occur when I replied to a new email from a Microsoft support engineer. The email would go through but I would get the “ ’gtLV’ is null or not an object” error message popup on the screen. If I replied to the email again the problem would not occur. A very similar message can be seen in the Microsoft Exchange Server forums where I also posted the provided solution.

After many emails to the very patient support tech at Microsoft (as I would reply and then send an email to let him know if the reply worked or not) we escalated the ticket and I got back the following resolution.

1. type regedit on command prompt or run
2. go to: HKCU\Software\Microsoft\Internet Explorer\Main
3. create TabProcGrowth (string or dword) and set the value to 0

This solution worked for me.  From what I can see at the ie8blog this has the side effect of reducing the protectedmode protection and I think the browser tabs use the same process rather than running in seperate processes.  This is a slight downside, but I doubt many users will care – they’re more than happy to have OWA working.

can’t change ie8 default search provider

IE8 in some situation disallows changing the default search provider. This can happen on workgroups and domains even if the “restrict changing search provider” gpo is not configured.

  • Make sure IE 8 is closed then navigate to registry key: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders
  • Add a new “Expandable String value” inside the above mentioned key with a value name of “AppData” and a value data of “%USERPROFILE%\Application Data”.
  • Reopen IE 8 and see if you still get the error message.
