Understanding the HubSpot Outlook Ecosystem: Desktop vs. Web Add-in

First things first, let’s clear up a common point of confusion. There are actually two main HubSpot add-ins for Outlook, and knowing which one you’re supposed to be using is super important:

HubSpot Sales Outlook Desktop Add-in: This is the older, traditional add-in that you’d typically download and install as a program on your Windows desktop.
HubSpot Sales Office 365 Add-in Web Add-in: This is the newer, cloud-based add-in that works across Outlook desktop Windows and Mac, Outlook on the web, and Outlook.com.

Here’s the kicker, and this is important: HubSpot is no longer actively developing or improving the HubSpot Sales Outlook desktop add-in due to some big changes Microsoft rolled out with the new Outlook for Windows. They’re actually recommending that most users switch over to the HubSpot Sales web add-in instead. If you’ve just moved to the “new Outlook for Windows,” the web add-in should even install automatically if you had the desktop version.

A big no-no: Whatever you do, don’t install both the desktop and Office 365 add-ins on the same device! They’ll clash big time and cause all sorts of problems with your sales tools. So, if you’re troubleshooting, figuring out which one you should have and making sure you only have that one is a crucial first step.

Common Reasons Your HubSpot Outlook Extension Might Be Stubborn

Before we jump into fixing things, let’s chat about why your HubSpot Outlook extension might be giving you grief. Knowing the root cause can save you a lot of troubleshooting time. Supercharge Your Outlook: The Ultimate Guide to the HubSpot Sales Extension for New Outlook

1. The Wrong Add-in for Your Setup

As we just discussed, this is probably the most common mix-up. If you’re using the new Outlook for Windows or Outlook for Mac, or even Outlook on the web, and you’ve got the old desktop add-in trying to run, it’s just not going to work right. Similarly, if your Outlook is installed from the Microsoft Store, it often won’t play nice with the desktop add-in. you usually need a “Click-to-run” version of Outlook.

2. Add-in is Disabled or Greyed Out

Sometimes, Outlook itself, trying to be helpful, might disable add-ins it thinks are causing performance issues or crashing. Or, the HubSpot icon might be there but just greyed out, making it unusable. This can happen if the Reading Pane is turned off, especially for the Office 365 add-in in desktop Outlook.

3. Login and Connection Hiccups

Even if the add-in is installed, if you’re not properly logged into your HubSpot account through the add-in, or if your internet connection is flaky, it won’t function. You might get stuck in a login loop or see error messages about not being connected. Also, your browser’s third-party cookie settings can mess with the web add-in’s login process.

4. Emails Not Tracking or Logging

This one is super frustrating because the whole point is to track your communications! If your emails aren’t logging or tracking, it could be because the “Track email” box wasn’t checked before sending, you’re sending in plain text instead of HTML, or even because the recipient’s email client or security software is blocking the tracking pixel.

5. Outdated Software or Conflicting Add-ins

If your Outlook isn’t updated to the latest version, or if the HubSpot add-in itself is old, you might run into compatibility problems. Plus, other add-ins you have installed can sometimes conflict with HubSpot, causing it to misbehave. Mastering the HubSpot Digital Marketing Certification: Your Honest Guide to Acing the Exam

6. Firewall or Security Software Blocking

Sometimes your computer’s firewall or other security programs might mistakenly see the HubSpot add-in’s communication with its servers as suspicious and block it, preventing it from working correctly.

7. Permissions and Account Issues

Your HubSpot account needs the right permissions to connect and use the sales tools. If these are off, or if you’re trying to use the add-in with an email account not connected to HubSpot, it won’t work.

Your Step-by-Step Troubleshooting Guide

Alright, let’s roll up our sleeves and get this fixed! We’ll start with the simplest checks and move to more involved solutions.

Step 1: Basic Checks and First Responders

Before you dive into anything complicated, give these quick fixes a try. You’d be surprised how often they work! Ultimate Guide to HubSpot Email Signature Creator

1. Restart Outlook and Your Computer

This sounds almost too simple, but it’s a classic for a reason! Often, a fresh start can resolve temporary glitches. Close Outlook completely, give your computer a full restart, and then open Outlook again. Check if your HubSpot add-in is back in action.

2. Verify Your Login Status

If the HubSpot add-in appears but seems inactive, or if it’s greyed out, make sure you’re actually logged in.

For the Desktop Add-in: Look for the HubSpot Sales icon in your Outlook inbox ribbon. Click it and ensure you’re logged in with your HubSpot credentials. You might see an orange or grey icon in your Windows system tray bottom right of your screen. if it’s grey, you need to log in there too.
For the Office 365 Web Add-in: When composing an email, look for the HubSpot icon often under “Apps” or an ellipses menu. Click it and log in if prompted. Make sure the “Remember me” box is checked if you don’t want to keep logging in.

3. Check for the Correct Add-in Installation Desktop vs. Web

Remember our discussion earlier? This is where it comes into play.

If you’re using the new Outlook for Windows, Outlook for Mac, or Outlook on the web: You should probably be using the HubSpot Sales Office 365 add-in web add-in. Check if you’ve mistakenly installed the older desktop version. If you have both, uninstall the desktop add-in.
If you’re on an older Outlook for Windows desktop version pre-new Outlook: You’ll likely use the HubSpot Sales Outlook desktop add-in.
How to check:
- For desktop add-in: Go to File > Options > Add-ins in Outlook. Look under “COM Add-ins.” If “HubSpot Sales” is listed, it’s the desktop version.
- For web add-in: In Outlook, go to File > Manage Add-ins or Outlook Web App > Settings > Manage add-ins. This will usually open a browser window showing your installed web add-ins.

4. Ensure the Add-in is Enabled

Sometimes, Outlook disables add-ins.

Go to File > Options > Add-ins.
At the bottom, next to “Manage: COM Add-ins,” click Go….
In the COM Add-ins window, make sure the box next to “HubSpot Sales” is checked. If it’s unchecked, check it and click OK. You might get a prompt to log in again after this. Restart Outlook if needed.
If you’re using the Office 365 add-in, check your “Manage Add-ins” section as described in step 3 and ensure it’s toggled “On.”

5. Turn on the Reading Pane for Greyed Out Add-in

If you’re seeing the HubSpot add-in greyed out in Outlook desktop, especially the Office 365 version, check if your Reading Pane is turned off. What Are HubSpot Extensions Anyway?

In Outlook, go to the View tab.
In the Layout group, click Reading Pane and select Right or Bottom to enable it. This often brings the add-in back to life.

Step 2: System and Software Deep Dive

If the quick fixes didn’t do the trick, let’s dig a bit deeper into your system and software.

1. Update Outlook and the HubSpot Add-in

Outdated software is a frequent culprit.

Update Outlook: Make sure your Outlook application is fully updated. Go to File > Office Account > Update Options > Update Now.
Update HubSpot Add-in: While the web add-in updates automatically, the desktop add-in might need a manual check. In Outlook, click the HubSpot Sales menu in the ribbon and look for an option like “Check for Updates”. Ensure you’re running a supported version of Outlook, typically Outlook 2013, 2016, 2019, 2021, or Microsoft Outlook for Microsoft 365 MSO. Some older versions won’t work.

2. Check Outlook Version Click-to-run vs. Microsoft Store

As mentioned, the desktop add-in specifically needs a “Click-to-run” version of Outlook, not one installed from the Microsoft Store.

Go to File > Office Account.
Under “About Outlook” or “Product Information,” you’ll see your version and installation type. If it says “Microsoft Store,” that could be your problem for the desktop add-in. If so, consider switching to the Office 365 web add-in or reinstalling Outlook as a Click-to-run version which usually comes with Office 365 subscriptions.

3. Reinstall the HubSpot Add-in

A clean reinstall can often resolve corrupted files or botched installations.

Uninstall First:
- For Desktop Add-in: Go to Control Panel > Programs and Features or Settings > Apps > Apps & features in Windows 10/11. Find “HubSpot Sales” and uninstall it.
- For Office 365 Web Add-in: Go to File > Manage Add-ins in Outlook. Find the HubSpot Sales add-in and remove it.
Restart Outlook and your computer if you uninstalled the desktop version.
Reinstall:
- For Office 365 Web Add-in Recommended: The easiest way is through Microsoft AppSource. Open Outlook, go to File > Manage Add-ins. In the Office Add-ins Store, search for “HubSpot Sales” and click Add. Follow the prompts. You can also get it from the HubSpot portal under Settings > Integrations > Email Integrations > Outlook Integration.
- For Desktop Add-in if you must use it for legacy reasons: Log into your HubSpot account, navigate to Settings > Integrations > Email Integrations. Look for the “Outlook Desktop Add-in” section and download the installer setup.exe. Run it and follow the instructions.

4. Clear Browser Cache and Cookies for Web Add-in/Outlook on the Web

If you’re using Outlook on the web or the Office 365 add-in, browser data can cause login loops or loading issues. Supercharge Your Inbox: The Ultimate Guide to the HubSpot Gmail Extension

Clear your browser’s cache and cookies. Specific steps vary by browser Chrome, Firefox, Safari, Edge, but generally, you’ll find this in your browser’s settings under “Privacy and Security” or “History.”
Also, ensure your browser isn’t blocking third-party cookies, as this can prevent the add-in from maintaining your login session.

Step 3: Advanced Troubleshooting Tactics

Still no luck? These steps might require a bit more technical know-how or even a chat with your IT team.

1. Check for Conflicting Add-ins

Other Outlook add-ins can sometimes interfere with HubSpot.

Under “Manage: COM Add-ins,” click Go....
Try unchecking other non-Microsoft add-ins one by one, restarting Outlook after each, to see if the HubSpot add-in starts working. If it does, you’ve found the culprit, and you might need to decide which add-in is more essential or look for alternatives.

2. Verify Email Format HTML vs. Plain Text

HubSpot’s email tracking relies on an invisible pixel, which requires emails to be sent in HTML format.

When composing an email, make sure you’re not in “Plain Text” mode. In Outlook, you can usually check this under Format Text tab in the message window.
Always ensure the “Track email” box is selected before sending if you want those notifications!

3. Adjust Firewall and Security Software Settings

Your firewall or antivirus might be blocking HubSpot’s connection.

Temporarily disable your firewall or antivirus software just for a moment, and only if you’re comfortable and know how to re-enable it quickly. Then, try using the HubSpot add-in. If it works, you’ll need to add an exception for HubSpot in your security software. You might need your IT team’s help for this. Ensure your firewall settings allow communication with *.hubspot.com via HTTPS.

4. Repair Your Office Installation

If Outlook itself seems buggy or corrupted, repairing your Office installation might help. HubSpot Demo Login: Your Ultimate Guide to Free Trials, CRM Access, & Test Accounts

Close all Office applications.
Open the Windows Start menu. Search for “Uninstall a program” or “Add or remove programs.”
Find your Microsoft Office or Outlook program in the list, click it, and select Modify or Change.
Choose Online Repair this is more thorough than Quick Repair and follow the prompts.

5. Check HubSpot Account Permissions

Make sure your HubSpot account has the necessary permissions for the sales tools to work with your connected inbox. If you’re part of a larger team, your HubSpot admin might need to review your user permissions.

6. macOS Catalina/Safari 13 Issues Web Add-in Pane Not Loading

If you’re on a Mac with macOS Catalina and Safari 13, and the Office 365 add-in pane isn’t loading, it could be Safari’s security settings.

Open Safari.
Go to Safari > Preferences in the menu bar.
Click the Privacy tab.
Clear the “Prevent cross-site tracking” checkbox. This can sometimes resolve loading issues with web add-ins.

7. Create a New Outlook Profile Mac Users

For Mac users experiencing persistent issues with add-ins, creating a new Outlook profile can sometimes clear out underlying corruption.

From Finder, open the Applications folder.
Ctrl+click or right-click Microsoft Outlook, then select Show Package Contents.
Open Contents > SharedSupport, and then launch Outlook Profile Manager.
Select the Create a new profile button and enter a name for the new profile. You’ll then need to set up your email accounts in this new profile.

Step 4: When All Else Fails – Contact Support

If you’ve gone through all these steps and your HubSpot Outlook extension is still not working, it’s time to reach out to the pros.

HubSpot Support: They have specific tools and insights into their add-ins. You can often send debug logs directly from the add-in itself to help them diagnose the issue.
Microsoft Support: If you suspect the issue is more with Outlook or your Office 365 account, Microsoft’s support team can help investigate.

Remember, the integration between HubSpot and Outlook is designed to make your life easier, not harder. By systematically going through these troubleshooting steps, you’ll likely pinpoint the problem and get back to seamless sales and communication in no time!
