A security update issued by Microsoft has caused us some headaches at clients that are Mac and PC based. It looks like the following update has made a security change to the Outlook handles jpg files and this is causing Outlook to have an issue decoding the files when saving from email.

If you open the file from Outlook Web Access or send it to an internet based email it opens fine.

There are a couple of ways to fix this problem.

I recommend that you contact Microsoft and get a hotfix from them for the issue. Just following this link http://support.microsoft.com/kb/951678/en-us and you can request access to the hotfix file. You will receive an email from Microsoft in a few minutes that will give you instructions on how to download and install the hotfix.

You can also uninstall the patch. You can do this by going to add/remove programs and look for “Security Update for Microsoft Office Outlook 2003 (KB945432)” and uninstall that.

Apparently this issue also effect Outlook 2007, but I have yet to see it. If you are having an issue with jpg attachments from a Mac and Outlook 2007 you can request a hotfix for it here http://support.microsoft.com/default.aspx?scid=kb;EN-US;952001

 I needed to uninstall Trend Micro Officescan Client from several computers a while back. The problem arose when no one at the company knew the password set when the software was installed. I found a way to bypass the password prompt that appears the moment you try to uninstall Officescan Client. Open up the registry editor(Start>Run>Regedit) and follow the path and instructions below:

HKEY_LOCAL_MACHINE\SOFTWARE\TrendMicro\PC-cillinNTCorp\CurrentVersion\Misc

On the right pane look for “Allow Uninstall” and then set its value to “1″.

Close the registry editor and run the Uninstall again and it should go through without asking for the password!
