Adding Mimecast to Outlook involves installing the official add-in from the company’s portal. If you are wondering how to open mimecast in outlook, the process is straightforward once you know the right steps. This guide covers everything from installation to daily use, ensuring you can manage your email security and archiving without hassle.

Mimecast is a powerful tool for email security, continuity, and archiving. It integrates directly with Microsoft Outlook, giving you extra features like message recall, large file sending, and advanced search. Whether you are a new user or troubleshooting an existing setup, this article walks you through each method.

Understanding Mimecast Integration With Outlook

Before diving into the steps, it helps to know what Mimecast does inside Outlook. The add-in adds a toolbar or ribbon tab, depending on your Outlook version. This tab gives you access to Mimecast-specific functions like archiving, message tracking, and secure delivery.

Mimecast works with Outlook 2013, 2016, 2019, 2021, and Microsoft 365. It also supports Outlook for Mac, though the steps vary slightly. The add-in is not automatic; you must install it manually or have your IT team deploy it.

Prerequisites For Using Mimecast In Outlook

  • An active Mimecast account with appropriate licenses
  • Outlook installed and configured with your email account
  • Administrator permissions to install add-ins (or IT support)
  • Internet connection for the add-in to communicate with Mimecast servers
  • Supported Outlook version (check Mimecast documentation for specifics)

How To Open Mimecast In Outlook

Now, let’s get to the main event. The exact phrase “How To Open Mimecast In Outlook” refers to both installing the add-in and accessing its features. Below are the primary methods.

Method 1: Install The Mimecast Add-In From The Microsoft Store

This is the most common method for individual users. Mimecast offers an add-in through the Microsoft AppSource store. Follow these steps:

  1. Open Outlook and go to the Home tab.
  2. Click on “Get Add-ins” (or “Store” in older versions). This opens the add-in store.
  3. In the search bar, type “Mimecast for Outlook”.
  4. Find the official Mimecast add-in and click “Add”.
  5. Review the permissions and confirm the installation.
  6. Once installed, you will see a Mimecast tab in the Outlook ribbon.

After installation, click the Mimecast tab to open the add-in. You may need to sign in with your Mimecast credentials. If you don’t see the tab, restart Outlook.

Method 2: Use The Mimecast Administration Console

For organizations, IT admins can deploy the add-in centrally. This ensures all users have it without manual steps. Here is how:

  1. Log in to the Mimecast Administration Console.
  2. Go to “Services” and then “Add-ins”.
  3. Select “Mimecast for Outlook” and configure the deployment settings.
  4. Choose the users or groups who should receive the add-in.
  5. Save the changes. The add-in will appear in Outlook after the next sync.

Users may need to restart Outlook or wait up to 24 hours for the add-in to appear. If it does not show, check with your IT department.

Method 3: Manual Installation Via The Mimecast Portal

If the store method fails, you can download the add-in directly. This is useful for offline installations or custom setups.

  1. Open a web browser and log in to the Mimecast portal.
  2. Navigate to “Personal Settings” or “Downloads”.
  3. Find the “Mimecast for Outlook” installer for your Outlook version.
  4. Download the file and run it as an administrator.
  5. Follow the on-screen instructions to complete the installation.
  6. Open Outlook and check for the Mimecast tab.

This method is less common but works well when the store is unavailable. Ensure you download the correct version for your Outlook (32-bit or 64-bit).

Accessing Mimecast Features In Outlook

Once the add-in is installed, you need to know how to open it and use its features. The Mimecast tab is your gateway.

Locating The Mimecast Tab

After installation, look for the Mimecast tab in the Outlook ribbon. It is usually between the “Help” and “Add-ins” tabs. If you don’t see it:

  • Restart Outlook completely.
  • Check if the add-in is enabled in Outlook’s add-in manager (File > Options > Add-ins).
  • Ensure your Outlook version is compatible.
  • Contact your IT support if the issue persists.

Common Mimecast Functions In Outlook

Here are the key features you can use from the Mimecast tab:

  • Archive Search: Search for emails stored in Mimecast’s cloud archive.
  • Message Recall: Recall or replace sent emails, even if already read.
  • Large File Send: Send files up to 2GB via Mimecast’s secure link.
  • Message Tracking: See if an email was delivered, opened, or blocked.
  • Secure Delivery: Send encrypted emails to external recipients.
  • Hold and Release: Manage quarantined emails directly from Outlook.

Each function opens a pane on the right side of Outlook. You can interact with it without leaving your inbox.

Troubleshooting Common Issues

Sometimes the add-in does not work as expected. Here are solutions for frequent problems.

Mimecast Tab Not Showing

If the Mimecast tab is missing after installation, try these steps:

  1. Go to File > Options > Add-ins in Outlook.
  2. At the bottom, select “COM Add-ins” from the dropdown and click “Go”.
  3. Check if “Mimecast for Outlook” is listed and enabled.
  4. If not, click “Add” and browse to the Mimecast installation folder.
  5. Restart Outlook.

If it still does not appear, reinstall the add-in using the manual method.

Login Errors When Opening Mimecast

When you click the Mimecast tab, it may ask for credentials. If login fails:

  • Verify your Mimecast username and password.

Add-In Slow Or Unresponsive

Performance issues can occur. Try these fixes:

  • Run Outlook in safe mode (hold Ctrl while opening) to test if the add-in works.
  • Reinstall the Mimecast add-in.
