Just can't get enough of IT

This blog is about mostly anything in IT. But the primary focuses are Microsoft Technologies like Exchange, Office 365, Azure and Cloud Security.

A new Exchange Server Conference is coming to Europe. 

The REAL Exchange Experience

In recent years, the main topics of the major Microsoft conferences have changed more and more towards cloud topics. The simplicity of migrating from on-premises Exchange Server mailboxes to Exchange Online is emphasized at each event. Also, new options have been made available to establish a full hybrid setup with Exchange Online more easily.

Topics covering the stable and secure operation of on-premises Exchange Server organizations have no room at these events. The REAL Exchange Experience wants to address the demand for topics related to the operation of Exchange Server in an on-premises IT infrastructure.

The conference will be held as a 1-day conference in different cities in Europe.

Enjoy Exchange Server 2019!

In Legacy Public Folder World with Exchange Server 2010 it was pretty easy to find the parent path of email enabled public folder:

(Get-MailPublicFolder MAILADRESS | Get-PublicFolder).ParentPath

 

Problem

When you try the same approach with modern public folders using Exchange Server 2013+ EMS, you receive an error.

Get-MailPublicFolder MSTeamsPF@varunagroup.de | Get-PublicFolder

Cannot process argument transformation on parameter 'Identity'. Cannot convert the "varunagroup.de/Microsoft 
Exchange System Objects/MSTeamsPF" value of type "Microsoft.Exchange.Data.Directory.ADObjectId" to type
"Microsoft.Exchange.Configuration.Tasks.PublicFolderIdParameter".
    + CategoryInfo          : InvalidData: (MSTEamsPF:PSObject) [Get-PublicFolder], ParameterBindinmationException
    + FullyQualifiedErrorId : ParameterArgumentTransformationError,Get-PublicFolder
    + PSComputerName        : P01.varunagroup.de

 

Solution

You need to use the EntryId paramater of the Get-MailPublicFolder result.

$pf = Get-MailPublicFolder MSTeamsPF@varunagroup.de

Get-PublicFolder -Identity $pf.EntryId

Name            Parent Path
----            ---------
MSTeamsPF       \Modern Collaboration

Get-PublicFolder does not take pipeline inputs.

When you install a Cumulative Update for Exchange Server 2016 you might receive the following informational message:

MAPI over HTTP, the preferred Outlook desktop client connectivity with Exchange server, is currently not enabled.
Consider enabling it using: Set-OrganizationConfig -MapiHttpEnabled $true
For more information, visit: http://technet.microsoft.com/library(EXCHG.150)/ms.exch.setupreadiness.WarnMapiHttpNotEnabl
ed.aspx

This modern protocol for Outlook has been introduced to Exchange Server with Exchange Server 2013 SP1. The protocol removes the dependency to the Windows Server RPC over HTTP component. The reduced complexity enhances the reliability of the client access protocoll. It's available for quite some time now. 

You can enable MAPI over HTTP on the organization level using the following Exchange cmdlet:

Set-OrganizationConfig -MapiHttpEnabled $true

You can still controll the protocol setting at the user level by deactiviting MAPI of HTTP for certain users, if required:

Set-CASMailbox -Identity [USER] -MapiHttpEnabled:$false

If your IT infrastructue is still not ready for MAPI of HTTP, your IT components pretty outdated. It's time to move forward and to modernize the infrastructure. 

NOTE
Did you know that MAPI over HTTP connects to Exchange Server using TLS to encrypt the connection? Even though that the protocol name is "overHTTP" it literally uses HTTPS securing the connection.


What are you reasons to not enable MAPI over HTTP? Let me know.

Exchange Server 2016Description

The script can be used to assign an application account (e.g. CRM, ERP) send-as permission to user mailboxes to send emails AS the user and not as the application.

This script loops through a membership list of an Active Directory security group. A single mailbox (CRM/ERP service account mailbox) is added to each mailbox (CRM/ERP user mailbox) of the security group members to provide send-as permission. 

The script has been developed as a solution to enable proper functionality with Dynamics NAV 2016.

 

Examples

 

# Assign Send-As permission to crmapplication@varunagroup.de for all members 
# of 'CRM-FrontLine' security group. The mailboxes as hosted On-Premises!
    
.\Set-SendAsPermission.ps1 -SendAsGroup 'CRM-FrontLine' -SendAsUserUpn 'crmapplication@varunagroup.de'
# Assign Send-As permission to ax@granikoslabs.eu for all members of 'AX-Sales' 
# security group. All mailboxes are hosted in Exchange Online!
    
.\Set-SendAsPermission.ps1 -SendAsGroup 'AX-Sales' -SendAsUserUpn 'ax@granikoslabs.eu' -ExchangeOnline

The Excel workbook Public-Folder-Migration-Actionplan-EN.xlsx spreadsheet is supposed to support you during a migration of Legacy Public Folders (Exchange Server 2010) to Modern Public Folders in Exchange Online.

The workbook consists of three spreadsheets:

  • Overview
    The spreadsheet "Overview" is used to define the names of the source and target platform. Additionally, you can define the names of the persons or groups responsible for the on-premises and cloud infrastructure. Those names are used in the second spreadsheet. You can define a start date for the migration project. There is no additonal calculation taking place. The date is just referenced in the second spreadsheet. It's up to your creativity to add automatic calculations. Finally, a summary for each available task status (Open, In Progress, Finished) is provided.
     
  • Public Folder Migration
    The spreadsheet "Public Folder Migration" contains the top down action plan for migration Legacy Public Folders to Modern Public Folders in Exchange Online. The required tasks are grouped and each task can be assigned and the status can be tracked. 
     
  • Lookup
    This spreadsheet is used to provided the task status lookup values.

Screenshot Public Folder Action Plan - Example

If you encounter any issues while preparing for migration or during migration of public folder, I recommend to check the Exchange Server Techcommunity Forum.
