I have an installation of an exchange 2003 server running on the domain controller and I' reading emails through Outlook 2007 client with no problems ntil know. Suddenly all emails in Outlook 2007 are shown as plain text. What's wrong? The only think changed on the clients is the upgrade of avg antivirus from 7.5 to 8. Do somebody knows if there is a way to change the way that emails are rendered in Outlook 2007? Thanks in advance.

I do not have OL 2007, but there should be a setting in the options concerning email format, unless there has been a policy enforcing plain text applied by the network admin.

Thank you ERTTED for your reply. I found that the problem was from a new installation of AVG 8.0 free edition, on the client. AVG scans every email and attach a "no virus ...." at the end. I disabled the notification, and it's working fine. Thanks anyway. Stelios

Stelios, I am having this same problem! How did you disable the notification? I can't find it anywhere. Any help is appreciated.. this plain text thing is driving me crazy. Thanks! hadria

Hadria,If you are using AVG 8.0 then just open up AVG and double click on the Email icon (top row on the right). Once the Email preference page loads you can make your changes there using the three check boxes on the bottom. Then Save. Hope this helps. -Justine

When using AVG 8.0 with Outlook 2007 you want emails to be scanned. Do not go to AVG User interface and diable scanning of emails. The solution is to go to tools, Trust Center, Add ins, And at bottom of Window there you manage addins. Click on arrow and show Exchange Client Extentions, Click go, uncheck the box by AVG Exchange Extention. This is the fix which worked for my company. It also works with Outlook 2003. In Outlook 2003 go to tools manage addins and do the same thing. Hope this helps others.

LIfesaver Rick. I have about 80 machines I've loaded with AVG and would have spent DAYS (literally) searching for a solution to this issue. Thank you for the TIP!!!!!

Rick - that got it thank you.

I have wasted many days trying to fix this on the asumption that it was an Outlook / Exchange problem. After finding and reading this all I had to do was disable the "certification" in the AVG advanced settings and it's fixed. Thanks muchly!

Thanks so much for the tip! Worked great. Wesley Jones

By unchecking the AVG Exchange Extension, you are disabling it causing Outlookto no longer use it to scan emails. What you want to do is open the AVG User Interface->click Tools->click Advanced settings...->click E-mail Scanner->uncheck Certify e-mail and then save your changes. This is what ol2ls refered to. ol2ls wrote: I have wasted many days trying to fix this on the asumption that it was an Outlook / Exchange problem.

AVG certifying the email (putting the No virus found.. message at the end of the email), causes some html email to not be seen by Outlook as html but as plain text. I only stumbled upon this recently. I just thought certain people were replying from mobile phones or just replying in plain text since it didn't happen to all my html email.

ChapsI am having the same problem but am running NOD32/64 on my new i7 rig. Not only does it not display HTML properly but sometimes it will bits off of an email altogether so I only get part of the message! It all used to work fine on my old PC but I cannot find the relevant check boxes in NOD - anyone know where to find them so I don't spends hours searching and so I can read my emails properly!Thanks in advance

I'm having the same problem but do not have AVG. Advice?

I found the only solution was to dump AVG. go to http://ninite.com/ and install the free MS Essentials or Avast.Darryl Gittins

As I can read and understand, by disabling the Exchange Client Extension will disable the e-mail virus scan as well, so the best will be to uncheck the e-mail certification. This change will apply only to new incoming messages...?
