This repository is the home of several scripts that are developed and maintained by Support Engineers for Microsoft Exchange Server. The scripts are intended for identifying and resolving a wide range of issues that impact on-premise or hybrid deployments and migrations. For more information, see the documentation for individual scripts.

It is recommended to use Visual Studio Code when developing scripts for this project. Opening VSCode at the root of this repo will ensure that VSCode uses the settings in the repro to enforce most of the formatting rules.
Before committing, .build\CodeFormatter.ps1 should be run. This script will apply PSScriptAnalyzer formatting rules, and will show any required changes in the form of a diff output. It's a good idea to set the following setting to avoid erroneous ^M characters in the diff output:
git config core.whitespace cr-at-eol
This repo uses a unique and fairly simple build system to create a single release script from a multi-file
script project. You can check the output of this system by running the .build\Build.ps1 script and
checking the dist folder. This system provides two ways to combine files into a single .ps1.
Dot-sourcing a script inside another script embeds the target script into the source script. For example, placing the following line inside of Script1.ps1 causes Script2.ps1 to be embedded at that point in Script1. Script2 is then excluded from release:
. .\Script2.ps1
You can embed any number of scripts. These could be in the same folder or in a child folder. See the
SourceSideValidation.ps1 script in this repo for an example of this.
Because dot-sourcing works normally at development time, the multi-file script can be run and debugged without building at dev time.
Non-script files can be embedded in a script as well. This is accomplished with the following syntax:
$someVarName = Get-Content .\someresource.txt -AsByteStream -Raw
This command populates $someVarName with the binary content of the target file. You can then use that
data however you like, such as converting it to text or processing it some other way. See the ExTRA.ps1
script in this repo, which embeds a .txt and .html file in this way.
Again, things work normally at dev time and can be debugged without building. However, note that -AsByteStream is only available in PowerShell Core, so PowerShell Core must be used at dev time for this type of script. The PowerShell Core requirement goes away in the release version since the file is then embedded in the script.
