Meeting invites not showing as tentative in calendar / Exchange 2010

I received a call from a user this morning that SOME meetings are not showing up in SOME users' calendars as tentative when they come in.

We're on Exchange 2010 SP3 RU2.  

Here's the situation on this one - invite came in to about four users.  Invite was from an external source.  For two of the users (That I believe were in the office at the time in Outlook), the invite was immediately put in their calendar as tentative.  

The other two users received the invite, but did not get a tentative meeting in their calendar.  The users were offsite and did not have Outlook open.  One user has delegates, one does not; both have iPhones and are using ActiveSync.

The user with the delegate - his delegate opened his inbox, did NOT go to the invite (She says) but as soon as she opened his inbox, the meeting immediately went to his calendar as tentative.

The user without the delegate - no one opened her inbox until I came along.  I went in through OWA to make sure the invite was in her inbox (It was.)  I verified the settings between all of the users both in OWA and EMC to make sure processing was being handled for calendar invites.  All four users are set the same.  Even when I opened this user in OWA, her meeting did not appear in her calendar as tentative.

I finally opened the user's Outlook as herself, and again - the meeting did not go in as tentative.  Meetings that have come in AFTER are in her calendar as tentative, and were in there before I started poking around.

Finally, once I opened the meeting invite in her Outlook (Just double-clicked it), it immediately went into her calendar as tentative.  This didn't happen in OWA, so I have to think something isn't right on the server side.  

Any suggestions on how to further troubleshoot?

Few items worth checking...

1. Do you have cache mode enabled/disabled for all affected users?
2. Do they have Outlook open on other machines (laptop etc.)?
3. Which version of iOS are they on?

Thanks,
Raj

1. Enabled for all.
2. No - they only have laptops and they were not in the office/using them at the time (For the two affected users.)
3. Two affected users are on 7.0.4.  Two unaffected users are on 7.0.1 and 7.0.6 (Soon to all be 7.0.6 if I have my way.)

Does any of the delegates have the affected mailboxes mapped to their profile by and chance?

Are there any rules in place moving the calendar invites to folders other than the inbox upon arrival?

No rules.  The invite was still sitting in the inbox unread when I began troubleshooting.

Re: delegates - remember, one of the affected user has NO delegates,

I would run EXBPA and this is something on client and i dont think this is some issue on server

Has this happened again or can be tested ?

I will run EXBPA - never hurts.  

Hasn't happened since, that I'm aware of, and I doubt we'll be able to easily test/duplicate it.

Not sure how this is client related though.  Meetings should process via the server so they're happening in real-time.  The idea behind putting meetings into your calendar as tentative is so that you don't get double-booked before you can decline/accept meetings.  If you're out of the office for two days. . .   That needs to work.  We did test this with others to make sure it was working properly without Outlook open, so that says server to me, no?

You can try disabling ActiveSync/BES or any other processe that could be reading the mailbox to see if it makes any difference.

The users aren't going to go for shutting down ActiveSync since we can test this issue "on demand."  

Again, this is only happening to a small percentage of calendar invites for a small percentage of users. . .  If it were every calendar invite for a particular user, would be much easier to diagnose.
