Seems since the Beta, that some emails that should be listed when drilling down the conversation view are totally missing.
Found this out when i knew for sure i had not deleted an email (huge conversation view concern), but the email was still not there.
Went to OWA, and the email was in my inbox, but not in outlook. Removing the conversation view displayed it, and it was visible for a bit while the conversation view was enabled, but once collapsed and then drilled back down, it disappeared again.
Totally random... not good.

Hi,

I had the exact same problem with Outlook 2010 Beta, using Exchange 2003 as the back-end. I have disable the exchange cache mode without any effect.
When the conversation view is turned on, some messages in threads are missing. I also checked with OWA and found that the missing messages are in fact in my inbox.
I turned off the conversation view and voilà, the missing messages are back.

Hope this gets fixed in RTM...

I too have had the feeling that the Conversation view does not always show you all the proper emails in a conversation thread.  I use IMAP folders and one of the mailing lists I am on seems to have the most problems.  Sometimes messages simply won't be displayed to me (and I ensure that I click the drill-down arrow twice to ensure the entire message thread is shown) and I have to disable conversations to find an email (the problem seems most prevalent when you get multiple replies to a thread and some of them quote previous emails... Outlook seems to hide the emails it thinks are quoted in newer replies so you don't have to read redundant email text).

I also have a problem where the Conversation view does not properly group all responses in to a single thread, yet Message-IDs are correct and In-Reply-To headers are as well - it simply thinks that some emails are a completely different thread and doesn't group all the emails together properly.  This makes following email mailing lists extremely difficult to do, and I find myself wasting considerably more time trying to read a thread of emails in Outlook 2010 than I ever did with 2007.

Hi, 

I have the same problem, but it is not a bug, it's a feature:

the "missing e-mails" are hidden because they are present in the "reply queue" of each listed e-mail.

if you look closely to your conversation, you will see that some e-mails have a multiple e-mail icon whereas some have a unique e-mail icon.

now if you look closely at some of the "multi e-mail" messages, you will find your missing e-mail by scrolling down the body of this message, you can also use the first/previous/next/last buttons which appears inside the e-mail.

this is an interesting feature, but unfortunately, few people now it and in my opinion, it is kind of annoying: it is unclear (you don't know which email you have actually read or not), messy (there are the usual from /subject fields and the multiple reply prefix symbol >, >> etc.) and not intuitive (you have to go deep inside the conversation to find the right information).

So please, allow to see each thread of e-mail in its entire normal UI as part of a conversation.

EDIT:

To see the "missing e-mails" you will have to expand the conversation by clicking twice (not double click) on the expanding arrow, the grouped e-mails are now shown.

if you clean-up a conversation, all this so-called "redundant" e-mails will be suppressed.

to turn-off the e-mail grouping, just select "Always expand conversations" in View -> conversations -> conversation settings.

Thomas, thank you! I was missing emails like crazy and kept having to turn off conversation view to find the message I was looking for. Your tip saves me a lot of time.
