A Collection of PowerShell Scripts and One-Liners to Use With Exchange Online
Not enough for a cookbook, just some recipes.
This repo is for anyone who manages Exchange Online using PowerShell. All the recipes solve a common administration problem. Use this information in any way that improves your process. If you want to know more about why this repo was created, read the FAQ.
You need a Microsoft 365 or Office 365 Subscription with access to Exchange Online. In addition to Exchange Online access, you may also need permissions or management roles assigned to your account. Review Microsoft's documentation on Exchange permissions here. If you need a test environment, sign up for a Microsoft 365 Developer account and use that tenant for testing. To execute commands, you must be connected to Exchange Online using the Exchange Online PowerShell V3 module. If you are not connected, you'll receive an error message.
