Step 1. Check the Outlook Add-ins:

1. In Outlook, go to File > Options > Add-ins.
2. Click Go next to Manage COM Add-ins.
3. Deselect to disable any third-party add-ins such as Adobe PDF and Adobe Document Cloud as they can conflict with the LEAP add-in (Microsoft add-ins are acceptable).
4. Ensure the LEAP Office for Outlook add-in is enabled.

Step 2. Verify Email and Data File Account Settings:

1. Open Outlook and go to File > Info > click on Account Settings > Account Settings. 
2. This will launch the Account Settings window.
3. Verify that email address in both the Email tab and the Data Files tab is the same one you use to sign into LEAP. Ensure that the email address has a tick next to it. Please note that IMAP/SMTP email accounts cannot be used.

Step 3. Enable Use Cached Exchange Mode to Download Emails to an Outlook Data File:

1. To enable Use Cached Exchange Mode, open Microsoft Outlook > click File > Account Settings > Account Settings.
2. Select your email address and then click the Change button.

   

3. This will launch the Exchange Account Settings window. Under Offline Settings, select and tick the option for Use Cached Exchange Mode.

   

4. Then click More Settings > Advanced tab.
5. Tick to select Use Cached Exchange Mode. Tick to select Download shared folders. Click OK.

   

6. Exit and then restart Outlook. By default, 12 months of your email is available offline, but you can control how much mail is kept offline.
7. If you are still experiencing issues with LEAP and Outlook, please perform an Automation Repair. You may also need to run Outlook as an Administrator.
