    How to force update GlobalAddressList in Office 365?

    This post explains how to manually force and update the global address list in Office 365.

    Updating the global address list requires to have the Address List Management role. By default, nobody has this role.

    1. Assign the AddressList Management role

      • Login with your administrator account to the Office 365 portal.
      • Go to Exchange Admin center, Permissions and admin roles.
      • Create a new role group and assign the AddressList role.addresslistrole

    2. Update the AddressList

    Once you have the AddressList role assigned, you can use the powershell commands to update the address list. You will have to wait for sometime until the new cmdlets are available.

    • First thing, logon to Exchange online using PowerShell.
    • $UserCredential = Get-Credential
      $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirection
      Import-PSSession $Session
    • Run the command Get-AddressList and verify that it’s working. (This may take some to work after creating the role)
    • RunSet-AddressList -Identity “All users”
    • Your address book is now updated
  • DNS broken after Windows Update KB3145126

    I noticed the DNS broke on my servers after Windows Update.

    The problem was KB3145126. Read more about it here.

    After a quick removal and reboot, DNS was operational again.

    To remove/uninstall KB3145126, open powershell and run the following:

    wusa.exe /uninstall /KB:3145126

    Hope this helps.

  • Updating the system time on Server 2008R2 & 2012R2 using NTP Servers

      1. To update, use the command below (2008 and 2012 server compatible)
        w32tm /config /manualpeerlist:"ntp_server" /syncfromflags:manual /reliable:yes /update
        

        change the ntp_server with your source. Check http://tf.nist.gov/tf-cgi/servers.cgi for servers

      2. Restart the time service
        net stop w32time
        net start w32time
      3. Resync the time
        w32tm /resync
      4. Verify your sync status
        w32tm /query /status

    Commands above should be fine if your sources are working correctly and/or your connection is OK (firewall or Microsoft Forefront can be an issue also).

    The commands below can help with troubleshooting

    To list out peers

    w32tm /query /peers

    To list out NTP Sources:

    w32tm /query /source
