Hi,

At my company they have there meeting room configured as a Resource in exchange so you can book it out at the same time of sending out the meeting requests. until recently this worked ok. However now when some tried to accept the meeting request they get the following system undeliverable message

Your message did not reach some or all of the intended recipients.

      Subject:      Accepted: Test
      Sent:      14/03/2011 11:21

The following recipient(s) cannot be reached:

      Contigo Meeting Room 1 on 14/03/2011 11:21
            You do not have permission to send to this recipient.  For assistance, contact your system administrator.
            <armstrong.contigo.co.uk #5.7.1>


I am assuming the issue is a permissions problem however I have given the everyone group full mailbox permissions to see if it is actualy a permissions issue but i still get the same issue.

Our current environment is Outlook 2007 / 2010 and Exchange 2003.

Followed this adivce on the meeting rooms Account and I no longer get any post master errors when I accept a meeting request however It does not show up as people have accepted the request.

Can you show a screen-shot of the Delivery Restrictions settings in your ADUC from a machine with Exchange management installed?

Also, Can you explain what you mean by "It does not show up as people have accepted the request."  What people?  The meeting room?

It seems user might have created the email address manaully, which is not matching with the system policy. Check it

Hi,

Sorry about the vague update anyway what I ment is the meeting request comes through into the users inbox. Then when they click accept they now get no errors. However if you go into the calandar and find the meeting it shows up as no one has accepted. I have checked again this morning and it is still showing up as nobody has accepted. Also just to clarify this a bit the calanadar that I'm looking at is the Calandar of the resource. However I have noticed though that the meeting request appears in the users calandar.

I will get a screen shot of the Delibery restriction settings in Active Directory now and attach to a later post.

The check box for authenticated users will make sure external address are not able to book the resource.  It should be safe to leave there.  The meetings should never originate from the resource, so let's look at this from a different angle:

1) Does the meeting organizer (requester) see that both invitees and resources have accepted?
2) Do other invitees see other invitees and resources have accepted?
3) When looking at the resource calendar, do the scheduled meetings show the free and booked times correctly?

>> I'm looking at is the Calandar of the resource.

so, on the calendar of the resource mailbox, you are trying to view tracking status?
If yes, i would differ that this shouldn't be there\available for the resource-mailbox

Reason: Normally when the Organizer sends-out the meeting-requests..the responses are collated @ the sent-item of the Organizer

Hi,

It is working ok now I get emails saying wether someone has accepted or not now and when I go to the event it says wether or not I have accepted however it doesnt show wether anyone else has accepted. It also does the same whether or not I book the meeting through the resources calandar or through my calandar.

Do me a favor and schedule two meeting requests.  Have one sent to one user only.  Have the other sent to that same user and your resource calendar.  See if you get the same or different results for acceptance notifications.

I have scheduled 2 meetings one through my calandar and one through the resources calandar they both do exactly the same and give any errors. However I still can't see who has accepted the meeting request (This is the case on both meetings i scheduled)

Hi,

I worked out it was 2 issues firslty a permissions issue as the user was part of multiple groups and one group had an explicit deny permission. However the fix I said earlier on also solved the other half of the problem.  Secoundly As e_aravind said it was an issue with the users way of organizing a meeting. I solved this by giving the user some training.
