This script has been developed for a custom project with the following requirements:
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.
The code samples utilize the following folder structure:
# EXAMPLE # Resize photos stored in the default PictureSource folder for Exchange On-Premises (648x648) and write images to user mailboxes .\Set-UserPictures.ps1 -ExchangeOnPrem # EXAMPLE # Resize photos stored on a SRV01 share for Exchange Online and save resized photos on a SRV02 share .\Set-UserPictures.ps1 -ExchangeOnline -PictureSource '\\SRV01\HRShare\Photos' -TargetPathExchange '\\SRV02\ExScripts\Photos' # EXAMPLE # Resize photos stored in the default PictureSource folder for Active Directory (96x96) and write images to user thumbnailPhoto attribute .\Set-UserPictures.ps1 -ActiveDirectory # EXAMPLE # Resize photos stored in the default PictureSource folder for Intranet (150x150) .\Set-UserPictures.ps1 -Intranet
When you integrate Skype for Business Server instant messaging with Exchange Server 2013 or Exchange Server 2016 you might encounter the following error in the OWA InstantMessaging log files.

The Exchange Server OWA host name must be the common name (CN) of the SSL certificate used securing OWA communication.
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.)
# 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
You implement shared mailboxes as part of a legacy public folder migration. Access to the shared mailbox provided by dedicated security groups which, in this case, provide access to dedicated sub folders within the mailbox.
The migrated legacy public folder content contained items marked as private.
When you access a shared mailbox as a group member you are not able to see or access private items.
The following two screenshots are used to demontraste the issue:
The Inbox node shows three unread items:
The Inbox detail pane just shows a single read message:
So how to access items marked as private?
The privacy level (Sensitivity) of a mailbox item is controlled by MAPI extended property 0x36.
When an item does have an extended property 0x36, the value is set to 0.
A mailbox is accessed using Exchange Web Services. The EWS endpoint is discovered using AutoDiscover for the selected mailbox.
The item modificatiuon is handled by the following code segment:
var extendedPropertyDefinition = new ExtendedPropertyDefinition(0x36, MapiPropertyType.Integer); int extendedPropertyindex = 0; foreach (var extendedProperty in Message.ExtendedProperties) { if (extendedProperty.PropertyDefinition == extendedPropertyDefinition) { if (log.IsInfoEnabled) { log.Info(string.Format("Try to remove private flag from message: {0}", Message.Subject)); } else { Console.WriteLine("Try to remove private flag from message: {0}", Message.Subject); } // Set the value of the extended property to 0 (which is Sensitivity normal, 2 would be private) Message.ExtendedProperties[extendedPropertyindex].Value = 0; // Update the item on the server with the new client-side value of the target extended property. Message.Update(ConflictResolutionMode.AlwaysOverwrite); } extendedPropertyindex++; }
RemovePrivateFlags.exe -mailbox user@domain.com [-logonly] [-foldername "Inbox"]
Search through the mailbox and ask for changing a item if -logonly is not set to true. If -foldername is given the folder path are compared to the folder name. If -logonly is set to true only a log will be created.
RemovePrivateFlags.exe -mailbox user@domain.com [-foldername "Inbox"] [-noconfirmation]
Search through the mailbox, if -noconfirmation is set to true all items will be altered without confirmation.
It should be noted that this solution is intended for use in migration scenarios.
When providing access to mailbnox delegates you can enable access to your private elements as well. But access to shared mailboxes is not configured using the delegation workflow.
The code has been tested using Exchange Server 2013 CU15.
The program utilizes log4net to log detailed information to the file system. The configuration is controlled by the application's config file.

This scripts checks multiple Exchange Server 2013 OWA web.config files for existence of IMCertificateThumbprint and IMServerName Xml nodes required for Skype for Business OWA integration.
This mostly required after installing a new Exchange Server Cumulative Update.
IMServerName is the FQN of the Front End Pool
IMCertificateThumbprint is the certificate thumbprint of the Exchange OWA certificate
Exchange Server 2016 stores the IM information in Active Directory.
