Exchange 2010 : Enable Resource Booking Attendant (in place of auto accept agent)

In a previous article I explained how to install and configure the auto accept agent (for exchange 2003)

Now, you have migrated your users from 2003 to Exchange 2010.

Some of your users was configured with Auto Accept Agent.

You want those users do the same they do in Exchange 2003.

1) Set the attribute IsResource for these users

In Exchange Management Shell, type:

Get-Mailbox -Identity YourMailBox | ft Name, IsResource

If result in IsResource will be FALSE then convert this mailbox with second command:

Set-Mailbox -Identity YourMailBox-Type Room

2) Activate the Resource Booking Attendant on the MailBox

In Exchange Management Console > Recipient Configuration > Mailbox > Properties

You can see now new Resource tabs have appeared.

Hit on Resource General and check "Enable the Resource Booking Attendant..."

Hit on Resource Information Tab and configure as you want.

You can remove it by running 'Remove-MoveRequest -MoveRequestQueue 'YourExchangeMailboxDatabase' -MailboxGuid MailboxGuidOfTheAccount'.

Access to the path ExchangeSetup\LPVersioning.xml is denied

If you encounter the message "Access to the path ExchangeSetup\LPVersioning.xml is denied" when installing Exchange 2010, it is possible that you try to do it via a copy of the installation DVD in a share or locally on the server (in the case of a virtual machine for example).

Then mount the iso in the VM and restart the installation process

Time configuration in a Windows Domain

Let’s go on with some configurations on Windows Server 2003 or higher OS:

- to configure the Domain Controller with the PDC Emulator FSMO to another time source, run:

w32tm /config /manualpeerlist:PEERS /syncfromflags:manual /reliable:yes /update
w32tm /resync /rediscover

Please set for PEERS the time source as listed above, either with it’s ip address or DNS name. If more then one is needed separate them with a space in between and don't forget the quotes: ""

Internet Time servers you can find here:

-->w32tm /config /manualpeerlist:"" /syncfromflags:manual /reliable:yes /update

- to configure a domain computer for automatic domain time synchronization, run:

w32tm /config /syncfromflags:domhier /update

After that you have to run:
net stop w32time
net start w32time

- to reconfigure the previous PDC Emulator, in case of transferring/seizing the FSMO to another Domain Controller, run:

w32tm /config /syncfromflags:domhier /reliable:no /update

After that you have to run:
net stop w32time
net start w32time

If you have to reconfigure a Windows 2000 Server Domain Controller, the steps are different after transferring/seizing the PDC Emulator role to another Domain Controller:

- you have to modify the "Type" value to "Nt5Ds" without the quotes under this registry key:

HKLM\ SYSTEM\ CurrentControlSet\ Services\ W32Time\ Parameters\

If you have problems with the time service configuration, because too many changes where done in the registry or you like start fresh on a computer, then you can reset the time service to a default state the following way. Make sure to use an elevated command prompt, to have full administrative permissions. Then type in the following commands:

net stop w32time

w32tm /unregister

w32tm /register

net start w32time
