Enable antispam functionality on Mailbox servers

9 de Novembro de 2017 – 12:45

Applies to: Exchange Server 2016

Topic Last Modified: 2016-03-28

Use the Install-AntispamAgents.ps1 PowerShell script to install and enable the built-in Exchange antispam agents on a Mailbox server.

The following antispam agents are available in the Transport service on Exchange 2016 Mailbox servers, but they aren’t installed by default:

  • Content Filter agent
  • Sender Filter agent
  • Sender ID agent
  • Protocol Analysis agent for sender reputation

You can install these antispam agents on a Mailbox server by using an Exchange Management Shell script, which is important if these agents are your only defense to help prevent spam. Typically, you don’t need to install the antispam agents on a Mailbox server when your organization uses other types of antispam filtering on incoming mail.

noteNote:
Although the Recipient Filter agent is available on Mailbox servers, you shouldn’t configure it. When recipient filtering on a Mailbox server detects one invalid or blocked recipient in a message that contains other valid recipients, the message is rejected. The Recipient Filter agent is enabled when you install the antispam agents on a Mailbox server, but it isn’t configured to block any recipients. For more information, see Recipient filtering procedures on Edge Transport servers.
  • Estimated time to complete this task: 15 minutes
  • You can only use PowerShell to perform this procedure. To learn how to open the Exchange Management Shell in your on-premises Exchange organization, see Open the Exchange Management Shell.
  • The Connection Filtering agent and the Attachment Filtering agent aren’t available on Mailbox servers. They’re only available on Edge Transport servers, and they’re installed and enabled there by default. However, the Malware agent is installed and enabled by default on Mailbox servers. For more information, see Anti-malware protection.
  • If you have other Exchange antispam agents operating on the messages before they reach the Mailbox server (for example, an Edge Transport server in the perimeter network), the antispam agents on the Mailbox server recognize the antispam X-header values that already exist in messages, and those messages pass through without being scanned again.
  • You need to be assigned permissions before you can perform this procedure or procedures. To see what permissions you need, see the “Transport configuration” entry in the Mail flow permissions topic.
  • For information about keyboard shortcuts that may apply to the procedures in this topic, see Keyboard shortcuts in the Exchange admin center.

PowerShell: Get-ADUser to retrieve password last set and expiry information

2 de Novembro de 2017 – 12:03
Get-ADUser -identity username -properties *
 get-aduser -filter * -properties passwordlastset, passwordneverexpires |ft Name, passwordlastset, Passwordneverexpires
get-aduser -filter * -properties passwordlastset, passwordneverexpires | sort name | ft Name, passwordlastset, Passwordneverexpires

Export the list to CSV so we can work on it in Excel. In this example we substitute, format table (ft) for select-object.

Type:

Get-ADUser -filter * -properties passwordlastset, passwordneverexpires | sort-object name | select-object Name, passwordlastset, passwordneverexpires | Export-csv -path c:\temp\user-password-info-20131119.csv

Office 365 : Password Sync doesn’t synchronize with Azure AD Connect

4 de Outubro de 2017 – 8:48

Verified password sync is disabled via using PowerShell

Following cmdlets have been used to verify above and I noticed password sync was in fact disabled although I checked the option in Azure AD connect setup.

Import-Module ADSync

Get-ADSyncAADPasswordSyncConfiguration -SourceConnector <‘LOCAL DOMAIN NAME>

Enabled password sync via PowerShell

Set-ADSyncAADPasswordSyncConfiguration -SourceConnector <‘LOCAL DOMAIN NAME> -TargetConnector <‘xxxxxxx.onmicrosoft.com – AAD’> -Enable $true

First you will need to download the Free Barcode Font from the following URL
Once downloaded follow the following steps.
1. Extract the ZIP file.
2. Click and Execute INSTALL.exe file.
3. After installation is completed restart your machine.

<asp:Button ID="btnGenerate" runat="server" Text="Generate" onclick="btnGenerate_Click" />

<hr />

<asp:PlaceHolder ID="plBarCode" runat="server" />
</form>

 


 
Imports System.Drawing
Imports System.Drawing.Imaging
Imports System.IO

 

 


Protected Sub btnGenerate_Click(sender As Object, e As EventArgs)
    Dim barCode As String = txtCode.Text
    Dim imgBarCode As New System.Web.UI.WebControls.Image()
    Using bitMap As New Bitmap(barCode.Length * 40, 80)
        Using graphics__1 As Graphics = Graphics.FromImage(bitMap)
            Dim oFont As New Font("IDAutomationHC39M", 16)

            Dim whiteBrush As New SolidBrush(Color.White)
            graphics__1.FillRectangle(whiteBrush, 0, 0, bitMap.Width, bitMap.Height)
            graphics__1.DrawString("*" & barCode & "*", oFont, blackBrush, point)
        End Using
        Using ms As New MemoryStream()
            bitMap.Save(ms, System.Drawing.Imaging.ImageFormat.Png)
            Dim byteImage As Byte() = ms.ToArray()
 
            Convert.ToBase64String(byteImage)
            imgBarCode.ImageUrl = "data:image/png;base64," & Convert.ToBase64String(byteImage)
