Upgrading to Outlook 2016 from Outlook 2010 Lost Emails: A Step-by-Step Guide to Resolve the Issue

If you have recently upgraded from Outlook 2010 to Outlook 2016, you may have encountered an issue where your emails are lost. This is a common problem that can occur during the upgrade process. However, there are several steps you can take to resolve this issue and get your emails back.

First, let's talk about the iCloud sync issue. If you're using iCloud with Outlook 2016, you may have noticed that it's not syncing as expected. This is because iCloud has switched to version 7 releases, which no longer supports older versions of Outlook. To resolve this issue, you'll need to update your iCloud software to the latest version.

To do this, simply open the Start Menu and type 'iCloud' in the search bar. This should return the 'iCloud Desktop app' as a result. Once you've opened the app, click on the 'Settings' icon (represented by a gear) in the top-right corner of the screen. From here, select 'Check for updates' to ensure that your iCloud software is up-to-date.

If updating your iCloud software doesn't resolve the issue, there may be an error with the APLZOD.DLL file. This file is responsible for syncing data between Outlook and iCloud. To fix this issue, you'll need to download and install a replacement copy of the APLZOD.DLL file from Microsoft's website.

Another possible cause of the problem could be an issue with your Registry settings. If you're still using Outlook 2007, you may need to set a Registry value to make iCloud work properly. To do this, follow these steps:

1. Open the Start Menu and type 'Registry Editor' in the search bar.

2. Click on the 'Registry Editor' result to open the program.

3. Navigate to the following key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\14.0\Outlook\Setup

4. Right-click on the 'Setup' key and select 'New' > 'String Value'.

5. Name the new value 'iCloudSync' and set its data type to 'REG_SZ'.

6. Click 'OK' to save the changes.

Once you've completed these steps, restart your computer and try opening Outlook again. If you're still having trouble, there may be an issue with your iCloud folders. To resolve this issue, follow these steps:

1. Open the Start Menu and type 'File Explorer' in the search bar.

2. Click on the 'File Explorer' result to open the program.

3. Navigate to the following location: C:\Users\\iCloud

4. Right-click on each iCloud folder (e.g., Calendar, Contacts) and select 'Properties'.

5. In the Properties window, click on the 'Security' tab.

6. Click on the 'Edit' button next to 'Permissions for '.

7. Check the box next to 'Full control' under the 'Allow' column.

8. Click 'OK' to save the changes.

By following these steps, you should be able to resolve the issue with your lost emails and get iCloud syncing properly with Outlook 2016 again. If you're still having trouble, there may be an additional issue that requires further troubleshooting.
