Exchange Server 2013Exchange Server 2016Description

 

This script has been developed for a custom project with the following requirements:

  • User photos are provided in rectangular format by the HR department and stored in a dedicated folder
  • User photos should be resized automatically to a square format to be suitable for
    • Active Directory thumbnailPhoto attribute (96x96 pixel)
    • Exchange user photo (648x648 pixel)
    • Intrant address book (150x150 pixel)
  • Processed photos should be moved to a processed folder
  • User logon names are used as user photo file names

The script utilizes a self developed C# command line tool, which has been published as open source at Github. The ResizeImage Wiki explains the usage of the command line tool. The application's configuration controls the target size and an optional pixel based offset.

Maybe the script will be useful in your project as well.

Requirements

  • ResizeImage.exe command line tool
  • GlobalFunctions PowerShell module as desribed here
  • Exchange Server 2013+ Management Shell (EMS) for storing user photos in on-premises mailboxes
  • Exchange Online Management Shell for storing user photos in cloud mailboxes
  • Write access to thumbnailPhoto attribute in Active Directory

Examples

The code samples utilize the following folder structure:

  • D:\UserPhotos
    • SOURCE
      Contains all .JPG user photos with file names matching the user logon names
    • AD
      Target folder for tumbnailPicture photos (96 x 96 px)
      • ResizeImage.exe
      • ResizeImage.exe.config (local configuration for Active Directory photos)
    • EXCHANGE
      Target folder for Exchange mailbox user photos (646 x 648 px)
      • ResizeImage.exe
      • ResizeImage.exe.config (local configuration for Exchange mailbox photos)
    • INTRANET
      Target folder for Intranet address book user photos (150 x 150 px)
      • ResizeImage.exe
      • ResizeImage.exe.config (local configuration for Intranet photos)

Exchange Server 2007Exchange Server 2010Exchange Server 2013Exchange Server 2016Description

This script gathers all public folders created during the last X days and exports the gathered data to a CSV file.

The script is not limited to legacy or modern public folders. It can be used with Exchange Server 2007/2010 and Exchange Server 2013/2016.

Use this script to identify users or departments creating to many folders in the public folder hierarchy. The CSV can be used to provide better guidance on public folder usage or can be used for planning public folder content migrations to other team based solutions (aka Shared Mailboxes, etc.)

 

Examples

# EXAMPLE
# Query legacy public folder server MYPFSERVER01 for all public folders created during the last 31 days
.\Get-NewPublicFolders.ps1 -Days 31 -ServerName MYPFSERVER01 -Legacy

# EXAMPLE
# Query modern public folders for all public folders created during the last 31 days
.\Get-NewPublicFolders.ps1 -Days 31

Exchange Server 2013Exchange Server 2016Description

This script helps administrators and support desk personnel to connect an Exchange Server 2013+ using remote PowerShell. You can either connect to a dedicated Exchange Server or connect to a randomly selected Exchange Server.

You can implement the function in your own scripts to connect to Exchange remotely. David Lee has written an excellent post about how to use saved credentials with PowerShell scripts.

Examples

# EXAMPLE
# Connect to the specified server EX01
./Connect-ToExchange.ps1 -Server EX01

# EXAMPLE
# Connect to a randomly selected server
./Connect-ToExchange.ps1
