Exchange: Renaming of room mailbox, Yeay or Nay?

From time to time we come across scenarios where a meeting room or resource has been removed, relocated or we simply would like it to show another name than the original one in our system.

So, is there an easy way to rename the resource in Exchange and have it reflected in the users calendar for previous bookings?

The answer is Yes, and No.

Renaming of the resource is fairly simple using PowerShell. You have to change the attributes Name, Alias, DisplayName, SamAccountName, and UserPrincipalName.

Set-Mailbox “TestRoom” -Name “NewTestRoom” -Alias “new_testroom” -DisplayName “New Test Room” -SamAccountName newtestroom -UserPrincipalName newtestroom@yourdomain.com

You also have to change the FirstName attribute using the Set-User command:
Set-User “NewTestRoom” -FirstName “NewTestRoom”

So, does this do the trick?

The answer is yes, in regards to new bookings. The problem is that the name change does not reflect in the previous bookings of the resource. The old name will still show in the booking, but if you click on the name of the room, the new name will show in the properties of the resource.

There is no way to change the name of the room without deleting the booking and make a new reservation with the new name. The room is reserved in the system with the old name, and there is no way for Exchange to display the new name in available resources(if you choose Change Room in the booking) without deleting the reservation and making a new one.

Skype for Business Event ID 1034.

After migrating to Skype for Business and removing Lync 2010/2013 pools, you may encounter an event ID 1034 stating that the LS File Transfer Agent encountered an error while accessing a file share.

The file share referenced will be the share on the removed Lync 2010/2013 pool. If you run the command Get-CsCentralManagementStoreReplicationStatus -CentralManagementStoreStatus, you will se an entry of DeletedReplicas that states the server FQDN of your deleted Lync pool/server. If the server is deleted from the topology not to be used again, you can proceed with deleting the server from the XDS database.

 

The easiest way to accomplish this, is to make sure that all Lync server components are removed from the Lync server in question. Simply go ahead and remove the Lync components from the server using Add/Remove programs. Make sure to reboot the server after the removal of the Lync components. The error message in the event log should disappear after this operation.

If this is not successfull, you will have to remove the replica ID’s from the SQL database(XDS).

This procedure from the UC Lobby blog by David Paulino should do the trick.

Issuing certificates with longer validity

Nice post, should be carried out in every environment where internal certificates are in use. Having the Lync/Skype for Business service beeing interrupted every second year because of short term internal certificates is nothing else but annoying.

Rune's blog about things I see and UC

In my previous job as a hired consultant I generally wanted the Lync/Skype for Business servers to have certificates lasting beyond the two year default validity period. Why? Because I, along with the customer, would consider a Lync or Skype for Business solution to have a horizon stretching beyond two years – and therefore issuing a certificate that would expire only after two years would be meaningless.

How to set IPv4 as preferred IP on Windows Server using PowerShell

Nice tip from Ståle Hansen on how to set IPv4 as preferred IP on Windows Server using PowerShell.

msunified.net

IPv6 Internet

Sometimes working with Lync and Skype for Business I see that the services are trying to contact other servers or localhost which returns an IPv6 address. If the service is set to run only on IPv4 the service will fail and not find the listening interface since it is not listening on IPv6. In these cases I do not disable IPv6 but prefer IPv4. This needs to be done in registry and a reboot is required after the change. Do not disable IPv6 on the network card because that will not work.

Here is a simple way to do it using PowerShell

Check the values below for other options

  1. Type to re-enable all IPv6 components (Windows default setting).
  2. Type 0xff to disable all IPv6 components except the IPv6 loopback interface. This value also configures Windows to prefer using IPv4 over IPv6 by changing entries in the prefix policy table. For more…

Skype for Business Online and PSTN Conferencing

As you all probably know, Microsoft has enabled the possibility of having Dial-in PSTN Conferencing in Skype for Business Online. In order to do this, you either have to have an E5 license plan in O365, or you can purchase the add-on for PSTN Conferencing in your excisting E1 or E3 plan.

PSTN Conferencing is a very valuable add-on to the O365 Skype for Business as it will enhance the possibilities of joining meetings without having to use a client.

To read more about PSTN Conferencing, visit this site on Microsoft.com:

Dial-in conferencing in Office 365

Missed Call Notification – Not Working…..

A known problem and the solution 🙂

UC Consultant Blog...

Since November 2015 there has been issues with Missed Call Notification from Lync/S4B to Outlook.
There has been written many blogpost about this, but I will here try to summarize how to fix it – Until Microsoft release a permanent fix for the issue.

The following Windows Update’s are relevant for this issue.

I have been trying to solve this at several customers, but made a breaktrough today.

I have been searching for KB3101496 – Nothing to find!
Searched in Registry clearly shows that the patch is installed, but it’s not visible in Control Panel

Exchange 2013 Event ID 1039: Failed to detect the bitlocker state for EDS log drive ‘C:\’.

I came across this event on an Exchange 2013 CU9 server which I was configuring for a customer.

EventID1039
Event ID 1039, Exchange 2013 CU9

Searching for solutions to this event made me understand that this is something that’s been going on since Exchange 2013 Cu7. The fix is quite simple and does not have any impact on the Exchange system.

Simply disable the Bitlocker check on the drive where diagnostics root directory exists.

Open below file in notepad (run as admin):
C:\Program Files\Microsoft\Exchange Server\V15\bin\Microsoft.Exchange.Diagnostics.Service.exe.config

Change the parameter “DriveLockCheckEnabled” value=”True” to “DriveLockCheckEnabled” value=”False” and save the config-file.

<!– Settings used when checking Bitlocker state of the drive where the diagnostics root directory exists –>
<add key=”DriveLockCheckEnabled” value=”False” />
<add key=”DriveLockCheckInterval” value=”00:00:10″/>
<add key=”DriveLockMaxDuration” value=”00:04:00″/>

Restart MicrosoftExchangeDiagnostics service, and the error message is gone.

Failed mailbox migration to Office 365: mrsproxy.svc’failed because no service was listening on the specified endpoint. The remote server returned an error: (404) Not Found

I was doing a migration between Exchange 2013 and Office 365 in a Hybrid configuration when I recieved the above error message. Couldn’t quite figure out why until I stumbled accross a forum thread that pointed me in the right direction.

This is what you have to check out and remediate if you have this error:

The ExchangeGuids of on-premise users are different to the ExchangeGuids of the corresponding users in Office 365.

Update the online user’s ExchangeGuid to match the on-premise ExchangeGuid and start migration.

1. On the on-premise Exchange server:

Get-MailBox -Identity userID | Select ExchangeGuid

2. In an Office 365 PowerShell session:

Get-MailUser -Identity UserID | Select ExchangeGuid

If the results don’t match, copy the guid result from command 1 and then run the following command in the Office 365 PowerShell session:

Set-MailUser -Identity userID -ExchangeGuid “copied guid”

Start migration:

$Cred = Get-Credential

$s = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell -Credential $cred -Authentication Basic -AllowRedirection

Import-PSSession $s

$OnPremAdmin = Get-Credentials

New-MoveRequest -identity “UPN” -Remote -RemoteHostName “remote host ex OWA URL mail.domain.com” -RemoteCredential $OnPremAdmin -TargetDeliveryDomain domain.mail.onmicrosoft.com
