What would cause the text from a string of emails to be removed from the email itself and then be attached as a a0000.htm document?

1. What type of email system is the outside user utilizing?
2. When did the a0000.htm first  appear, i.e. in a REPLY from the Outside user?
3. How many back and forth replies were there and perhaps you can map it out i.e.

INSIDE USER 1 - Sent Message to INSIDE USER 2 & 3 and Outside User 1 (just one outside person correct?)

INSIDE USER 2 & 3 RECEIVE message as constructed
OUTSIDE User receives original message ( as constructed, with htm?)

WHO REPLIED NEXT and then what happened to that reply for all parties.

Follow it until you see the HTM arrive.

I suspect its something with the outside system but walk this through and we can see about tracking it down.

Sounds as though an inline content disposition issue and I am betting its happening outside your environment.  I have seen this happen but not for a long time and usually from a firm that has a really old Exchange system or a Linux SendMail or other mail product that treats the inline message as an attachment.

here is an entry about one such issue http://www.linuxquestions.org/questions/linux-general-1/forcing-email-message-body-inline-not-attached-492130/

Let me know what you discover and we cant continue to work on it if needed but I think the above steps will confirm that its an outside server issue and nothing to worry about.  Maddening yes but not a major issue.  If you indeed see that its an issue on the other side perhaps you can discuss with their email admin if this is an outside firm you work with allot, however if not I wouldn't waste the time IMO

1, The Title mentions 2010 SP1 RU1 and not sure if you are making a statement that "This started happening right after you applied this SP/RU"  OR that it just happens to be what you are running SP level wise?

2. How long has this been going on?

3. Do you know the content that is being removed?

4. Are you running AV on the exchange server or at the SMTP gateway?

5. What is in the a0000.htm file? (Obviously open with an editor, not as a web page to ensure its not a virus load"

6. What version of Outlook?

7. RECIPIENT(S): is this happening to one, user, multiple users?

8. SENDER(S): Are all the emails from specific users, domains, Internal Users only, External Users only etc ?

NOTE: One of the things that may help is analyzing the logs to see if it can shed some additional light on whats happening with these messages check out this article http://blogs.msdn.com/b/scottos/archive/2007/07/12/rough-and-tough-guide-to-identifying-patterns-in-ese-transaction-log-files.aspx

This issue was first brought to my attention after I installed RU1 for SP1

2. How long has this been going on?
We just noticed this issue happing on an email sent to one of my users last week.

3. Do you know the content that is being removed?
The content being removed is the conversation taking place between the 3 recipients.  The body of the email was there last week, when the user went to review the email he noticed the body was gone and only his response was there.  There was an added attachment of A0000000.htm that contained the missing body of the email.  It was a lot of information that contained the back and forth conversation taking place.  I checked the other users computer and the email appeared the same way in her inbox, the body was gone and it contained an attachment with the missing information.

4. Are you running AV on the exchange server or at the SMTP gateway?
 I am running a file level forefront security

5. What is in the a0000.htm file? (Obviously open with an editor, not as a web page to ensure its not a virus load"
The file contains the entire missing body of the email.  The entire conversation that took place is the A000000.htm

6. What version of Outlook?
Both users are running outlook 2007, I do not know what the user outside our organization is running.

7. RECIPIENT(S): is this happening to one, user, multiple users?
So far, only one has been brought to my attention.

8. SENDER(S): Are all the emails from specific users, domains, Internal Users only, External Users only etc ?
The email string was between two users in house and one person outside of our organization.
