how to connect to exchange online single line from powershell.

In this video, I will show you how to connect to Exchange Online with PowerShell using the best method. Exchange Online is the cloud-based version of Microsoft's email and calendar service, and it's part of the Microsoft 365 suite of products. To connect to Exchange Online with PowerShell, you need to install and use the Exchange Online PowerShell module, which supports modern authentication and works for accounts with or without multi-factor authentication (MFA).
The Exchange Online PowerShell module is a set of cmdlets that you can use to manage your Exchange Online organization from PowerShell. You can perform tasks such as creating and modifying mailboxes, groups, contacts, permissions, policies, and more. You can also use the module to run reports and troubleshoot issues.
powershell
$PSVersionTable.PSVersion
Get-Module -ListAvailable PowerShellGet,PackageManagement
If you don't have the required version or modules, you can follow the instructions in this article¹ to install them.
Once you have the prerequisites, you can install the Exchange Online PowerShell module by running this command in PowerShell:
powershell
Install-Module -Name ExchangeOnlineManagement
You may need to confirm the installation and accept the license agreement. If you get an error about an untrusted repository, you can run this command to change the repository trust level:
powershell
Set-PSRepository -Name PSGallery -InstallationPolicy Trusted
Then try to install the module again.
After you have installed the module, you can load it by running this command in PowerShell:
powershell
Import-Module ExchangeOnlineManagement
Now you are ready to connect to Exchange Online with PowerShell. To do that, you need to run the Connect-ExchangeOnline cmdlet with your user principal name (UPN), which is your email address. For example:
powershell
Connect-ExchangeOnline -UserPrincipalName [e-mail]
This will prompt you to enter your password and sign in to your account. If you have MFA enabled, you will also need to complete the verification step. After you sign in, you will see some information about the module and your connection.
You can verify your connection by running some Exchange Online cmdlets, such as Get-Mailbox or Get-User. For example:
powershell
Get-Mailbox -Identity [e-mail]
This will show you some details about your mailbox.
You can also use other parameters and options with the Connect-ExchangeOnline cmdlet, such as:
- `-Credential` to specify a different credential object than your current user.
- `-Device` to use device code authentication instead of interactive authentication.
- `-DelegatedOrganization` to connect to another tenant as a Microsoft partner.
- `-ShowBanner` to hide or show the banner information after connecting.
- `-UseRPSSession` to use remote PowerShell instead of REST API (not recommended).
To disconnect from Exchange Online PowerShell, you can run this command:
powershell
Disconnect-ExchangeOnline
This will close your session and free up resources.
