How to Fix "Connect-MsolService: Unable to Complete This Action. Try Again Later" in 2025

Have you ever tried connecting to Microsoft Online Services using PowerShell, only to hit a frustrating wall with the error: "Connect-MsolService: Unable to complete this action. Try again later"? If so, you’re not alone! This pesky issue has been tripping up IT admins and tech enthusiasts alike, especially in 2025, as Microsoft continues to evolve its cloud ecosystem. But don’t worry—I’m here to guide you through this like a tech wizard with a magic wand (or at least a solid PowerShell script!).

In this ultimate guide, we’ll dive deep into why this error happens, how to troubleshoot it step-by-step, and—most importantly—how to fix it for good. Whether you’re a seasoned IT pro or just dipping your toes into Azure AD management, this article is packed with unique insights, practical solutions, and a sprinkle of humor to keep things light. Let’s get started and banish that error once and for all!

What Does "Connect-MsolService: Unable to Complete This Action" Mean?

Before we jump into fixes, let’s break down what’s going on. The Connect-MsolService cmdlet is a PowerShell command from the MSOnline module. It’s your key to managing Microsoft 365 or Azure Active Directory (AD) services—like user accounts, licenses, or domains—straight from your command line. When it works, it’s a breeze. But when you see "Unable to complete this action. Try again later", it’s like the universe telling you, “Not today, buddy.”

This error typically means PowerShell can’t establish a connection to Microsoft’s online services. It’s vague, annoying, and leaves you scratching your head. But here’s the good news: it’s usually fixable with a little know-how.

Why Does This Error Happen?

There’s no single culprit—it’s more like a rogue’s gallery of tech gremlins. Here are the most common reasons in 2025:

• Authentication Issues: Your credentials might be off, or multi-factor authentication (MFA) is throwing a curveball.

• Outdated Modules: The MSOnline module might be stuck in the past while Microsoft’s servers are living in the future.

• Network Glitches: Firewalls, proxies, or just plain bad internet can block the connection.

• Deprecation Drama: As of 2025, Microsoft is phasing out older tools like MSOnline in favor of Microsoft Graph. This could be a nudge to upgrade.

• Service Outages: Sometimes, Microsoft’s servers take a coffee break, and you’re left waiting.

Now that we know the “why,” let’s roll up our sleeves and tackle the “how” with some expert-level troubleshooting.

Step-by-Step Solutions to Fix the MSOLService Connection Error

Ready to kick this error to the curb? Here’s a detailed, foolproof plan to get Connect-MsolService working again. Follow these steps in order, and we’ll have you connected faster than you can say “PowerShell wizard.”

Step 1: Check Your Basics—Credentials and Internet

Let’s start simple. Even tech experts trip over the basics sometimes!

• Verify Your Credentials: Double-check your username and password. If you’re using MFA, make sure you’re ready to authenticate with your second factor (like a phone app).

• Test Your Internet: Open a browser and visit portal.office.com. If it loads fine, your connection’s good. If not, fix your Wi-Fi or yell at your ISP (politely, of course).

Run this quick test in PowerShell:

Connect-MsolService

If it prompts for credentials but still fails, move to the next step.

Step 2: Update the MSOnline Module

In 2025, using an outdated MSOnline module is like trying to play a 4K game on a floppy disk—it just won’t work. Microsoft deprecated the Azure AD and MSOnline PowerShell modules in 2024, but they’re still functional (barely) until March 30, 2025. Let’s make sure you’ve got the latest version.

1. Check Your Current Version:

  Get-Module -ListAvailable -Name MSOnline | Select-Object Name, Version

If it’s older than 1.1.183.66 (the last stable release), time to upgrade.

2. Update the Module:
   Open PowerShell as an admin and run:

  Install-Module -Name MSOnline -Force -AllowClobber

If it’s already installed, this forces an update. Say “Yes” to any prompts about untrusted repositories.

3. Import the Module:

  Import-Module MSOnline

Try connecting again:

Connect-MsolService

Still no luck? Onward!

Step 3: Handle MFA Like a Pro

Multi-factor authentication is great for security but can mess with Connect-MsolService. Here’s how to deal with it in 2025:

• Use Modern Authentication: Older versions of MSOnline struggle with MFA. After updating (Step 2), you should get a modern login prompt instead of a legacy one.

• Test Without Credentials: Run Connect-MsolService solo. It’ll pop up a login window where you can enter your details and complete MFA.

If you’re automating scripts and can’t deal with prompts, consider switching to Microsoft Graph PowerShell (more on that later). For now, test this:

Connect-MsolService

Success? Great! If not, let’s dig deeper.

Step 4: Troubleshoot Network Issues

Your network might be the silent saboteur. Here’s how to sniff out the problem:

• Check Proxy Settings: If you’re behind a corporate proxy, it could block PowerShell’s connection. Run this to bypass it temporarily:

 $Proxy = [System.Net.WebRequest]::GetSystemWebProxy()

 $Proxy.Credentials = [System.Net.CredentialCache]::DefaultCredentials

• Test Connectivity: Ping Microsoft’s servers:

 Test-NetConnection -ComputerName "login.microsoftonline.com" -Port 443

If it fails, your firewall or network admin is the next stop.

• Disable VPN (Temporarily): If you’re on a VPN, disconnect and retry.

Now test:

Connect-MsolService

If it’s still a no-go, don’t panic—we’ve got more tricks.

Step 5: Switch to Microsoft Graph (The 2025 Way)

Here’s the big news: Microsoft wants you off MSOnline and onto Microsoft Graph PowerShell SDK. As of March 30, 2025, MSOnline is on life support—security fixes only. If the above steps fail, it’s a sign to modernize.

1. Install the Graph Module:

  Install-Module -Name Microsoft.Graph -Force

2. Connect to Graph:

  Connect-MgGraph -Scopes "User.Read.All", "Directory.Read.All"

This pops a login window. Sign in, and you’re in Graph territory!

3. Replace MSOnline Commands:

• Instead of Get-MsolUser, use Get-MgUser.

• Check Microsoft’s migration guide for equivalents.

Why switch? Graph is faster, more secure, and future-proof. Plus, it might dodge your connection error entirely.

Step 6: Check Microsoft’s Service Status

Sometimes, the problem isn’t you—it’s Microsoft. In 2025, service outages are rare but not impossible.

• Visit the Microsoft 365 Service Health Dashboard.

• Look for issues with Azure AD or PowerShell connectivity.

If there’s an outage, grab a coffee and wait it out. Otherwise, proceed.

Step 7: Advanced Fixes (For the Brave)

If you’re still stuck, let’s get technical:

• Clear PowerShell Cache: Corrupted files can cause chaos. Uninstall and reinstall MSOnline:

 Uninstall-Module -Name MSOnline -AllVersions

 Install-Module -Name MSOnline

• Use a Different Machine: Test on another computer to rule out local issues.

• Event Logs: Check Windows Event Viewer under “Applications” for clues about the failure.

Retry:

Connect-MsolService

Preventing the Error in the Future

Congrats—you’ve (hopefully) fixed it! Now, let’s keep it from coming back:

• Stay Updated: Regularly update your PowerShell modules.

• Embrace Graph: Transition to Microsoft Graph for long-term stability.

• Monitor Network: Keep an eye on proxies and firewalls.

• Backup Credentials: Use a credential manager to avoid typos.

FAQs About "Connect-MsolService: Unable to Complete This Action"

Why is MSOnline deprecated in 2025?

Microsoft is pushing Microsoft Graph for better security and features. MSOnline gets security fixes only until March 30, 2025.

Can I still use Connect-MsolService after March 2025?

Yes, but it’s risky—unsupported modules might break anytime.

What if MFA is required for my account?

Update MSOnline or switch to Graph, which handles MFA seamlessly.

How do I know if it’s a Microsoft outage?

Check the Microsoft 365 Service Health Dashboard.
