Trend Micro AV
I have an email issue on our network, it happens only occasionally and to date it has effected 5 users at differing times.
When an email is either replied to or forwarded internally it strips out all the previous content and effectively sends the email blank apart from our internal signatures.
It does not affect all emails sent from any one account, the email will also behave the same if forwarded from the account that received it even if that user has not experienced that problem before.
This is not down to Outlook 2007 message settings as far as I am aware, the settings are set for forwarding and replying to “include original message text”.
If I forward the complete message to myself, it removes the content. If I then forward it to gmail it arrives with everything intact, it also will arrive back into my mailbox complete if forwarded from gmail.
I have disabled Trend on my machine, so effectively this is not the cause. Also I am not running PGP desktop with any encrypted software, as the email I forward from my own account to my account does not go through the gateway I assume PGP is not the culprit either.
If I track the email with the Microsoft Exchange Troubleshooting Assistant, I see the messages that arrived but the byte count is 18259 as opposed 51782 that is on the full email content.
I really need to get to the bottom of this, our business environment is in pensions and having users not being able to forward messages is getting a pain.
I am sure this explanation is about as clear as mud ¿, let me know if anyone needs more info before providing a possible solution to tracking the path of the email to see what the offending software is that is doing this.
Thanks for any assistance in advance.
