Cached exchange mode mail to keep offline

Cached Exchange Mode (CEM) is a feature in Microsoft Outlook that allows you to keep your email data offline, while still maintaining a connection to the Exchange server. This mode is useful when you need to work offline or have limited internet connectivity.

Here's how to enable Cached Exchange Mode in Outlook:

For Outlook 2013 and later versions:

1. Open Outlook and go to File > Account Settings > Account Settings.
2. Select your Exchange account and click on the "Change" button.
3. In the "Change Account" window, click on the "More Settings" button.
4. In the "Exchange Advanced" window, scroll down to the "Offline Settings" section.
5. Check the box next to "Use Cached Exchange Mode".
6. Click "OK" to save the changes.

For Outlook 2010 and earlier versions:

1. Open Outlook and go to File > Account Settings > Account Settings.
2. Select your Exchange account and click on the "Change" button.
3. In the "Change Account" window, click on the "More Settings" button.
4. In the "Exchange Advanced" window, scroll down to the "Offline Settings" section.
5. Check the box next to "Use Cached Exchange Mode".
6. Click "OK" to save the changes.

When you enable Cached Exchange Mode, Outlook will store a local copy of your email data on your computer. This allows you to access your email, calendar, and contacts even when you're not connected to the internet. However, keep in mind that any changes you make to your email data while offline will be synchronized with the Exchange server the next time you connect to the internet.

Some benefits of using Cached Exchange Mode include:

• Faster performance: Outlook will load faster because it doesn't need to connect to the Exchange server for every request.
• Offline access: You can access your email, calendar, and contacts even when you're not connected to the internet.
• Reduced bandwidth usage: By storing a local copy of your email data, you'll use less bandwidth when you're connected to the internet.

However, there are also some potential drawbacks to consider:

• Increased storage requirements: Cached Exchange Mode requires more storage space on your computer to store a local copy of your email data.
• Potential for data inconsistencies: If you make changes to your email data while offline and then connect to the internet, there's a risk that the changes may not be synchronized correctly with the Exchange server.

Overall, Cached Exchange Mode can be a useful feature for users who need to work offline or have limited internet connectivity. However, it's important to weigh the benefits and drawbacks before enabling this feature.
