Out-of-Office (OOF) messages have to follow the compliance rules as regular email communication. This is not necessarily a known fact to end users.
If a company does have a strict compliance policy regarding external OOF messages you can use the following solution to establish a strict and simple to use OOF configuration.
Only specific employees are supposed to send OOF messages to external recipients. All other employees are supposed to send internal OOF messages only.
The solution consists of two PowerShell scripts.
The first script is used to remove any exisiting OOF rules created by a user using the Outlook OOF Rule Wizard. This is required to avoid any strange behaviours in regards to OOF messages being sent even if OOF is deactivated. The most common reasons for such a behaviour are migrated OOF rules created by previous Exchange Server versions.
You can read more about scripts here:
You can use the follow command line example, if you want to automate the execution of script 2 using a scheduled task.
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -version 3.0 -command ". 'D:\Program Files\Microsoft\Exchange Server\V15\bin\RemoteExchange.ps1'; Connect-ExchangeServer -auto; "D:\Scripts\Set-ExternalOOF\Set-ExternalOOF.ps1 -RemoveRights"
This script searches for OOF rules created by users using the Outlook rule-tab in the OOF assistant and deletes exisiting OOF rules.
In preparation to configure compliant Out-Of-Office (OFF) settings for users, any existing OOF rule needs to be deleted. The script will use either an exisiting Exchange Server EWS library or the Managed EWS library installed using the default file path.
This is the first of two scripts for the complete solution. Find the second script here.
The script access the mailbox rules using Exchange Web Services. Therefore the account executing the script either needs to have ApplicationImpersonation rights or full access to the user mailbox.
# EXAMPLE 1
# Find any existing OOF rule and write results to log file
# EXAMPLE 2
# Find and delete any existing OOF rules in all user mailboxes and write delete actions to log file
# EXAMPLE 3
# Find and delete any existing OOF rules for user SomeUser@varunagroup.de and write delete actions to log file
Remove-OOFRule -Mailbox SomeUser@varunagroup.de -Delete

This script sets the mailbox ExternalOofOptions to 'External' for members of a given security group.
ExternalOofOptions for users that are NOT a member of the security group will be set to 'InternalOnly'. If required the script will set the ExternalAudience to None and will delete an existing OOF message.
Controlling the ExternalOofOptions and ExternalAudience settings has been implemented to follow dedicated company compliance rules.
This is the second of two scripts for the complete solution. Find the first script here.
# Run script with default settings
Troubleshooting Active Directory Federation Services is a tedious tasks for any administrator. Therefore, I've started this blog post to have a comprehensive overview of information sources.
The following list provides links for Active Directory Federation Services troubleshooting:

This script fetches emails from a given monitoring mailbox by searching email messages for a given subject string. In this case email messages sent by the ENow Management Suite (http://enowsoftware.com/). Status messages are parsed to extract Disk Performance alert data for further processing in Power BI.
The mailbox is queried using Exchange Web Services (EWS). The EWS endpoint is identified by AutoDiscover.
The script exports the following columns for further processing:
You can easily adjust the script to fit your requirements. Search for other message subjects and parse for other content in the message body.
# Run script using default parameters
This example shows that P04 and P08 have exceeded the critical and warning state disk performance thresholds more often than the other servers.
The next example shows the same date in a different report.
