Exchange 2010 Decline When Room is Double-Booked, NO Delegates!!

I want Users to be notified when their meeting conflicts with another meeting as soon as they try to book it.
I don't want automatic approval, no delegates, just simply want them to use their Scheduling Assistant to see when they can book and if it overlaps another meeting it will instantly tell them.
I don't want to select any recipients in the Resource In-Policy Requests or the Resource Out-of-Policy Requests. No Registry Key edit either! Allow conflicting meeting requests is unchecked.
PLEASE HELP!!!!!
Resource Booking in Exchange no longer works like that.
If you want to try to emulate the way it used to work, you to configure direct booking which is done at the Outlook level. That requires a registry key.
http://support.microsoft.com/kb/982774
Direct Booking does not successfully book a resource in Outlook 2010
You need to also open each resource mailbox in Exchange, give the users the correct permissions to place meetings directly on the resource calendars and set the auto Acccept/ decline options in Outlook.
There is no quarantee this will work in Exchange 2013 and beyond.

Exchange Server 2010 Room Mailboxes Double Booking

We are have several room mailboxes setup on Exchange Server 2010 and are having an issue with rooms being double booked.
I have "Allow Conflicting Meeting Requests" unchecked on the Resource Policy Tab but if a user try's to book a room that is already reserved it gets accepted and put on the calendar.
How do I stop this from happening?
Here are the settings for the room:

IsValid                             : True

The most common cause of this issue is that you have both Outlook Direct Booking and AutoAccept enabled. To fix this logon to the Mailbox using Outlook and disable direct booking see (or use a script) http://blogs.technet.com/b/exchange/archive/2013/07/15/a-significant-update-to-remove-directbooking-script-is-now-available.aspx

Exchange 2013 Allows Room/Resource Double Booking (By Design!)

Since upgrading to Exchange 2013 we have noticed a significant increase in users complaining about room double bookings. After a fair bit of testing we were able to narrow the behaviour down to a reproducible scenario.
First things first - we have AllowConflicts set to false on all room and resource mailboxes, so that is not the issue.
The problem manifests if the start date of a recurring meeting series is more than six months in the past.
This is the scenario which we can reproduce:
Find (or create) a meeting room which is configured to not allow booking conflicts (AllowConflicts:False)
Book one or more meetings in the room (or look for existing meetings)
Create a recurring meeting (or use an existing meeting)
with a start date which is more than six months in the past which will conflict with one or more of the bookings created or found in step 2.
The room will accept all instances of the new recurring meeting, even those which conflict with other bookings.
A variation of the scenario is to extend an existing recurring meeting series:
Find (or create) a meeting room which is configured to not allow booking conflicts (AllowConflicts:False)
Find (or create) a recurring meeting with a start date which is more than six months in the past
and which will end soon.
Book one or more meetings in the room in the same time slot as the recurring meeting
for dates past the end of the recurring meeting series.
Extend the recurring meeting from step 2 past the meetings from step 3.
The room will accept all instances of the extended meeting series, even those which conflict with other bookings.
This is new behaviour in Exchange 2013 - in Exchange 2010 these scenarios worked and Exchange didn't allow double bookings.
We opened a case with Microsoft and were eventually told that this new behaviour is 'by design'. We even appealed to the customer advocacy group and the Exchange product team still refuse to acknowledge this as a bug. As a workaround it
was suggested that we reduce the booking window horizon to 180 days, but this does not resolve the issue.
We are not happy; our users are not happy.
I'm posting here to share our findings with other Exchange users who may be seeing this issue, and to ask you to please share your experience and, if possible, contact Microsoft so that the product group might reconsider their position on this behaviour.
Ben Lye

So it seems like I should have been a little clearer - the scenarios above are for reproduction. I know that nobody normally creates a recurring meeting with the start date in the past - that step was just to emulate an existing meeting which was created
more than six months ago.
The current explanation from Microsoft is that Exchange 2013 only checks the first six months of a recurring meeting series for conflicts, so another way to encounter (or reproduce) this issue is this:
Find (or create) a meeting room which is configured to not allow booking conflicts (AllowConflicts:False)
Book a new recurring meeting which starts today and has an end date at least six months in the future.
Create a new single meeting instance in the same time slot as the recurring meeting, but after the end of the recurring meeting series.
Extend the meeting series beyond the date of the single meeting instance
The room will accept the update to the series and the room will be double booked.

Exchange 2010 - Issues with Room Finder not showing available rooms.

Hi,
We are having issues with room finder not populating the room resources that are available inside a meeting request within outlook 2010. It also appears that there is a drop down box that is present in a lot of the other forums and pages that I have referenced
for troubleshooting:
Single Exchange 2010 server version 14.03.0224.002 running all roles. Migrated from previous Exchange 2003 environment and old 2003 server has been decommissioned.
Room mailbox created and all configured resource policies are working correctly for creating meeting requests. A distribution group was created and the room mailboxes added to this DG as per instructions here: hxxp://exchangeserverpro.com/find-meeting-rooms/
. We have recreated the OAB and confirmed that the Room mailboxes are part of this list.
Does anyone have any ideas why the rooms are not showing up in the Room Finder box?
If I have missed any information please feel free to ask for more info.
Thanks, all help will be appreciated.

Hi,
According to your description, I understand that room finder cannot show available room in Outlook 2010.
If I misunderstand you concern, please do not hesitate to let me know.
I want to double confirm whether it works before, or it can’t work after decommission Exchange 2003? How about other Outlook version?
The offline address book (OAB) is generated by Microsoft Exchange Server. In order for the Room Finder feature to work, the OAB must be generated by Exchange 2010 or a later version.
Please run Get-OfflineAddressBook | FL Identity,Server to double check OAB generation server. Also, run Get-OabVirtualDirectory | FL to check URL for current OAB VD and force update OAB.
Then open Test E-mail AutoConfiguration to double check whether Outlook get correct URL.
After above complete, please try to switch to Send/Receive tab, click Send/Receive Groups, and then click Download Address Book.
Thanks

ICal, Macbook Air, and Exchange 2010

I have a user whos iCal is not syncing with Exchange 2010. When creating a new event, it gives the message "iCal can't save the event "xxxx" to the Exchange server. The account "xxxx" currently can't be modified. To discard your changes and continue using the version of your calendars that's on the server, click Revert to Server. To save your changes on your computer until the problem is resolved, click Go Offline."
The user is on a 2011 13" Macbook Air, 1.86 GHz Core 2 Duo. Snow Leopard 10.6.7, iCal 4.0.4. Mail and Address Book sync fine. The calendar works fine from the users iPhone, Outlook Web Access, and Outlook 2011 on the computer.
I have tried deleting the account, deleting all caches, and recreating it, but it still doesn't work. I created the account on my Macbook and it works fine, no problems syncing over wired or wireless connections. Macbook is also on 10.6.7, iCal 4.0.4. So I was thinking it was an account issue. I created a new account on the Macbook Air, set up the exchange account in iCal, and I get the same problem as on the original account, no syncing.. I have everything set up exactly the same as on my Macbook, but the Macbook Air refuses to sync. This error only appears when an event created on the Macbook Air is in the calendar. It pulls events from the server fine, but once an event is created it refuses to cooperate.
Do Macbook Airs just not play nice with Exchange?

This is not an issue with the Macbook Air. I have had this same problem since upgrading to Lion. One solution suggested (from MacRumors.com forum reply) was to
1) Open iCal and go into the iCal Menu/Preferences. Go to Advanced tab and enable Time Zone Support. Close iCal
2) Open System Preferences and click on Date & Time. Click on Time Zone tab and enable the checkbox for auto detect time zone.
I did this several times without success before I finally got rid of the errors. I have been error free for 3 weeks, but today the error is back (with no apparent changes made by me). I'm still struggling to get rid of it now.

Conference Room issue, double bookings allowed even though AllowConflicts is set to False

Hi. I used ADsi Edit to completely delete/remove my public folders database. I now run Get-PublicFolderDatabase and it doesn't find one, so I think I have completely removed it. My issue is that all my conference rooms are now allowing double bookings
even though AllowConflicts is set to False. I'm pretty sure I have jacked this up due to deleting the public folder database. What should I do to correct this? Thanks. John

Exchange 2010 deployment in Exchange 2003 Environment

Hello,
I have recently installed Exchange 2010 in an Exchange 2003 environment. I need some help migrating all my settings over to Exchange 2010
-- mailboxes, recipient policies, offline address book, free/busy, etc.
I have looked at these following TechNet sheets for assistance, but getting a bit confused:
http://technet.microsoft.com/en-us/library/aa996719.aspx (Exchange 2013 System
Requirements)http://technet.microsoft.com/en-us/library/ee332348.aspx (Upgrade
from Exchange 2003 Client Access)http://technet.microsoft.com/en-us/library/aa998186.aspx
(Exchange 2003 - Planning Roadmap for Upgrade and Coexistence)http://technet.microsoft.com/en-us/library/ee681662.aspx (Install
Exchange 2010 in a Mixed Exchange 2003 and Exchange 2007 Organization)
I have two domain controllers. Exchange 2010 is not installed on a DC, but Exchange 2003 is on one of them. I want to eventually decommission
the Exchange 2003 environment and implement and Edge Server in its place. Exchange 2010 is installed on a Virtual Machine. It's running SP3, the latest service pack. Exchange 2003 is on a physical machine and it's running SP2.
Please help me simplify what exactly I need to do to migrate 2003 configurations over to 2010.
Thank you for you much appreciated assistance.

Hi
I would install a new DC and seize the MSO roles to the highest server. Remember you can install server 2012 but not R2 yet.
You can setup your connectors on exchange 2010 to send/receive mail to the internet. make sure your ISP allows the new server.
You can also setup a routing group connector so that mail flows from EX2003 to EX2010 and vice versa during your transition period.
Remember to replicate your public folders to the new server and if you have a lot of data be patient. Once you happy with everthing then decomission the old DC.
Hello,
All FSMO roles are transferred (not seized) on my Windows 2008 R2 Standard Domain Controller. I transferred all the roles off my Windows 2003 Domain Controller. The W2K3 DC is also my Exchange Server 2003 SP2. I specifically did not want to
install Exchange 2010 on a DC. It's on its own member server.
Should I make the Exchange 2003 Server a Front-End Server when I create a routing group for mail flow to Exchange 2010? I want to eventually implement an Edge. Also, can I have mail flow from the Internet directly to the Hub and bypass the Exchange
2003 mail flow?

Unable to SEND mail using Activesync in Exchange 2010 server on iPhone or Windows Mobile 6.1

Hi All,
We've been setting up a new SBS 2011 server for a client this week. Everything is working, except the staff have 4 x iPhones to connect with Exchange ActiveSync.
There are 2 x iPhone 4's and 2 x iPhone 3Gs's. We can setup the Exchange accounts on each of the phones and they are all able to sync mail and calender etc with the server.
The problem we have is when any of them try to send mail from the phone, it gives an error : "Cannot Send Mail - An error occurred while delivering this message" and it sits in the outbox on the phone.
The newsgroups and forums are littered with people having issues with IOS4 and Exchange 2010 but most of these are from June-August 2010 when IOS4 version was around 4.00 or 4.01
A lot of these people had iPhone 3 handsets running with IOS 3.1.3 which worked with Exchange 2010 but when they upgraded to IOS 4, they had this problem sending mail.
It seems that for most of them, the fix came in the form of IOS version 4.1 which fixed the send issue for them.
We have a variety of Hansets and IOS versions (including an iPhone 3Gs running IOS 3.1.3) but are unable to send mail from any of them:
iPhone 3Gs    IOS 3.1.3
iPhone 3Gs    IOS 4.3.3
iPhone 4       IOS 4.3.3
iPhone 4       IOS 4.3.5
I was surprised that the iPhone 3Gs running 3.1.3 was unable to send either as nearly all the forums etc I read with this issue said the iPhone 3's worked with that IOS version.
Today we used a test iPhone 4 handset from our office to connect to an almost identical Small Business Server 2011 we setup two weeks ago for another client.
The test iPhone 4 was able to connect, Sync and Send email on that server but when set it to connect to this SBS 2011 server, it gets the "Cannot Send Mail" message the same as the others. So clearly the handset is working (on the other server at least),
it must be something misconfigured in this Exchange server right?
We ran the Exchange Remote Connectivity Analyser on the Exchange server and got green ticks across the board.
Outlook Web App and Outlook Anywhere both work normally. Everything we can test on the Exchange server works except sending from any iPhone.
Having said all that, I just setup a Windows Mobile 6.1 handset to sync with the Exchange 2010 server as a test, and it appears to have the same issue.
It will connect & Sync Mail, Contacts and Calendar but if trying to send an email from the phone, it will just sit in the outbox.
Does anyone have some insight into what the problem may be?

Further to this .. I found the solution on a MS Exchange 2010 support forum.
It was not a certificate or firewall issue, looks as thought the “Accepted Domains” in Exchange Mgmt Console –
Org Config – Hub Transport cannot have any spaces in the name field.
I had some spaces and the emails were not downloading fully and able to send. Once I removed the spaces from the Name field and
restarting the Exchange and IIS services emails were now being sent and received ok.

No Free/Busy Information for Exchange 2010 users in Outlook 2010 client, 2010 OWA shows this information fine

I have looked for hours and hours on Google and this web site for this type of issue and nothing seems to help.
Problem:
On my new Windows 2008 R2 /Exchange 2010 server with IIS7 installed, I can use Outlook 2010 client to login and send and receive e-mail but when I try to busy search internal Exchange users I get no information (cross-hatch), but the sender of the Meeting Request
can see their own free/busy information fine. And OWA users can see free/busy information fine, as can Outlook 2003 client users against this Exchange 2010 server when logged in.
I don't know if I have a certificate problem with regard to IIS7 or Exchange 2010, I did not create my own certificate , it is just what was installed by default when I installed and configured Win2K8 server, IIS7 and Exchange.
On the Windows 7 workstations with Outlook 2010 client, I am not logging into the Exchange 2010 server DNS domain, if that makes any difference. On these workstations I can ping "autodiscover.my.exchange.server.com" and my.exchange.server.com
with no problem. I even used this Microsoft KB to install a new _autodiscover dns entry, but it did not help :
When I turn on logging on my Outlook 2010 client, I see this in my C:\Users\Administrator\AppData\Local\Temp\1\outlook logging\20131208-135658864-fb.log :

Hi,
How many users encounter this issue, all users with Outlook 2010 or some specific users?
According to your post, the Error code 600 indicates that your Autodiscover service is working well. as for the certificate mismatch issue, we can also following the KB below to resolve it:
http://support.microsoft.com/kb/940726/en-us
The Free/Busy information in Exchange 2010 is using the Availability service to
retrieve it. Please directly access
https://mail.mydomain.ae/EWS/Exchange.asmx in IE and see whether a proper XML file is returned.
Or we can go to

Exchange 2010 anti-spam does not work after uninstalling Forefront

I installed Forefront Security for Exchange for testing, and later removed it because I couldn't afford to let Forefront use over 1GB of RAM on my server. After removal, the built-in anti-spam wasn't working anymore. I discovered that content filtering had been disabled, so I re-enabled it but spam still sails on through. I reinstalled the hub transport role and enabled anti-spam, but the spam keeps on coming. I checked the headers on incoming email for SCL and PCL stamps, there are none. What else can I check that Forefront may have monkeyed with?

Hi,
Thank you for the post.
Before going any further, I’d like to confirm whether you have installed Forefront Security for Exchange(FSE) on Exchange 2010. In fact, it cannot be installed.
As far as I know, you should install Forefront Protection 2010 for Exchange Server (FPE) on Exchange 2010. When you installing FPE, the opt into antispam will disable Exchange's basic content filtering agent as FPE installs its own content filtering agent. And uninstalling FPE will not re-enable this agent so you will have to do so manually.

Exchange 2010 Management Role loading slowness

Hello,
I'm new to the company I currently work for and relatively new into IT, and one of the first issues I have noticed here is how incredibly slow Exchange 2010 is when loading.
I'm aware there are numerous topics covering this issue after having done many checks on search engines, however most of them seem to advise going to IE and un-checking the boxes defining Certificate Revocation or other solutions that I haven't found to
be applicable, at least not to my knowledge. I have tried the first suggestion but found this made no difference.
We don't get any error messages when loading but it is generally a little slow, however the issue is where it says "Getting management role information for: domain/user info etc...", at the end of the progress bar. It will sit there for
6 minutes before finally loading and allowing me in. This happens every time you use it also, not just the first time, whether it's on the local machine of anyone in IT or on the server.
I've checked the server's available resources and it seems to be more than enough, although it is a virtual server so I'm not sure whether that changes what the issue could be.
Would anyone be able to help point me in the right direction of what I could be checking for? Sorry if this is a really vague question or I've not provided enough detailed information, but any help would be really appreciated. I'm sure one of the more experienced
members of my new team could take a look but I figured I'd try and make a good impression!
Apologies if this is in the wrong forum section also.
Thanks very much

Hi
Thanks for the reply.
We're on Exchange Server 2010 SP3 (14.03.0158.001), as far as I can tell it's all up to date.
Server specs:
OS - Server 2008 R2 Enterprise, 64bit
RAM - 32GB
Processor - Intel Xeon E5-2690 @ 2.90GZ, 16 Cores, 16 Logical Processors
There's 433 mailboxes in total, spread over 19 databases (a database for each department), 17 of those being mounted and active.
Once I'm into the management console and can use the various features, the performance is generally fine, it's just that initial loading where it hangs.
Thanks

Outlook 2010 / Exchange 2010 prevent double room booking

Hi,
I have a problem with double-booking of rooms in my company. I've read pretty much everything I could find on this subject and I'm still not satisfied. I setup a room in Exchange with these settings:
- Resource Booking Attendant: disabled
- Allow conflicting meetings: disabled
- Delegate of the mailbox: UserDelegate
- Users who are allowed to submit in-policy requests that will be automatically approved: Selected recipients (none)
- Users who are subject to approval by delegate (within in-policy): all users
- Users who are allowed to submit out-of-policy requests: selected recipients (none).
I believe this is supposed to work like this: everyone can request a meeting and every meeting request has to be accepted by a delegate (UserDelegate in this case). There are no conflicts allowed.
However, it doesn't work that way. Let me give you an example of how it does work.
User1 requests a meeting in a MeetingRoom1. UserDelegate accepts the meeting, and everyone can see in MeetingRoom's calendar that the room is booked (permission set to default=reviewer). Then User2 requests a conflicting meeting at the same time and the
same room. It is not automatically rejected and can still ask for approval. UserDelegate still receives a request and CAN agree to it - even if there is conflict. Sure, there is a notification of a conflict, but room can be double booked anyway.
Let's say UserDelegate sees the notification of a conflict and rejects the meeting. User2 get an email that says his meeting was rejected, but in his calendar the meeting is still on. It doesn't disappear. It leads to conflicts, when 2 users show up at the
MeetingRoom1 and they both claim they booked the room - which is true, even though one of them was rejected. He didn't realize, since the meeting was still active in his calendar...
If I enable Resource Booking Attendant the User2 request would be denied automatically and the notification would be sent, but the meeting remains in the calendar. Besides, I don't want it to be enable, since it automatically agrees to all meetings if there
is time and space for it. I have a UserDelegate who's supposed to decide who gets the room.
I tried to EnableDirectBooking=1 in registry in Outlook, but it doesn't work. Users still can requests the meeting.
So, in short: I don't want users to be able to book an already booked room. Can you help me with that? I can provide screenshots and EMS if you need me to.

Hello,
Declined meeting will stay in the organizer's calendar. This behavior is by design. It is convenient for the meeting organizer to check the meeting information, change the location to another room and send updates for other attendees. If the organizer want
to remove this meeting, he needs to decline the meeting and send decline updates to other attendees.
Since this issue is more related to Exchange side, I'd recommend you post your question to the Exchange forum for further assistance:

Exchange 2010 resource mailbox double booking issue..

Hi,
I have moved the meeting room mailbox from exchange 2003 to 2010:
set-Mailbox -Identity:<resourcename> -Type:Room
but after that, the meeting room can be double booking in the same time.
I have tried folllowing command, but it's failded.
Set-CalendarProcessing -Identity <mailbox identity> -AllowConflicts:$false
Thanks.

Hi Martina,
I appreciate this is an old post, however if you do pick up on this could you please advise on your statement from the above:
"Even if the room sends a Decline, as it should when a conflict is found, you will still see that meeting request in your own Calendar."
This is the exact behaviour happening at a customer of ours at the moment. However they don't want the meeting requests to appear/remain in the Calendar of the person trying to book the meeting room.
Do you know of a way to stop this behaviour?
Do you know if the meeting request is only populated in the Calendar of the user who tries to book an appointment in the resource calendar or does this appear in other perspective attendees Calendars?
Many Thanks,
Matt.

Exchange 2010 Room Calendar Permissions are too permissive when Default is set to None.

Help! Room Calendar permissions are too permissive when Default is set to None.
We are a brand new Exchange 2010 shop, and have setup several conference rooms. Many of them are restricted to specific groups to book via In-Policy Requests using Resource Booking Attendant. The Room Calendar permissions for most
rooms shows only two options for the Default access: None and Full Details. Default is set to None, yet if someone opens the room calendar in Outlook (& they are not part of the In-Policy restrictions) they are able to see the full meeting details
(even open the meeting for full details). How is this possible when by default they should not have any access as it is set to None? Some rooms would not be a problem for clients to see the details, but some rooms like Executive rooms need to be
locked down so that others cannot see the room details - None.
I also found this, although it did not make a difference. If I create an Outlook profile for the room and login as the room calendar in Outlook, go to File, Options, Calendar, Resource Scheduling, Set Permissions I get different default options:
None, "Free/Busy time", "Free/Busy time, subject, location" and Full Details. Why do I have more options in this view rather than the Room Calendar Permissions? I looked at two rooms and both Default options were set to "Free/Busy
time", so I changed these settings to None. Still the clients can view the full room calendar details. What are we missing to get the room calendar locked down so it is not displaying details to everyone?

Only the default groups and Exchange Admins have Full Access to these items, so that is not the issue.
-MailboxFolderPermission 1RP07AWest:\Calendar cmdlet and it shows the same access I see when I open the calendar in Outlook and view the Permissions as shown below - Default is set to None.
As I stated in my last reply the only thing that finally forced it to be blocked is changing the Resource Scheduling permissions under Options > Calendar for that room mailbox. If I have to do that for each room calendar, it's going to
take considerable time to change each one. Is there a cmdlet to allow me to access and change that setting as well?
