Connecting to Exchange Online using PowerShell can often be challenging, especially when you want to avoid the overhead of using a web browser. Many IT professionals prefer a direct method to automate their processes. This article will guide you through the steps to connect to Exchange Online using your credentials without a browser.
Understanding the Problem
If you've ever needed to connect to Exchange Online programmatically but were frustrated by the requirement of browser authentication, you’re not alone. Many users want a straightforward method to log in with their credentials directly from PowerShell. Here’s the original code you might have encountered:
# Attempt to connect to Exchange Online via browser
Connect-ExchangeOnline -UserPrincipalName [email protected]
While this code attempts to connect to Exchange Online, it prompts the user for browser authentication, which may not be ideal for scripts or automation.
Correcting and Simplifying the Connection Method
To connect to Exchange Online without launching a browser, you can use the -Credential parameter along with a stored credential object. Below is an improved version of the code that can achieve this:
# Store your credentials securely
$UserCredential = Get-Credential -Message "Enter your Exchange Online credentials"
# Connect to Exchange Online
Connect-ExchangeOnline -Credential $UserCredential
In this modified code, the Get-Credential cmdlet prompts you to enter your username and password securely. This information is then passed to the Connect-ExchangeOnline cmdlet without requiring browser-based authentication.

Practical Example: Automating User Mailbox Management
Let’s say you want to automate the process of retrieving mailbox statistics for multiple users. Here is an example script:
# Store credentials
$UserCredential = Get-Credential -Message "Enter your Exchange Online credentials"
# Connect to Exchange Online
Connect-ExchangeOnline -Credential $UserCredential
# List all mailboxes and display their size
Get-Mailbox -ResultSize Unlimited | ForEach-Object {
$Mailbox = $_
$Stats = Get-MailboxStatistics -Identity $Mailbox.UserPrincipalName
[PSCustomObject]@{
DisplayName = $Mailbox.DisplayName
TotalItemSize = $Stats.TotalItemSize
ItemCount = $Stats.ItemCount
}
}
# Disconnect from Exchange Online
Disconnect-ExchangeOnline -Confirm:$false
This script connects to Exchange Online using the credentials you provide and retrieves mailbox statistics for all users, displaying their display name, total item size, and item count.
Benefits of Connecting Without a Browser
- Automation: Ideal for scripting and scheduled tasks where user input is not feasible.
- Security: Protects credentials from exposure in browser sessions.
- Efficiency: Streamlines the process, making it faster to execute commands without unnecessary prompts.
