Causes of [pii_email_d48dafe949943a3da519] Error:

1. Outdated Outlook Version

One of the common causes of the [pii_email_d48dafe949943a3da519] error is using an outdated version of Microsoft Outlook. When you use an older version of Outlook, it may not be fully compatible with your email service provider, leading to compatibility issues that trigger the error.

Clearing the cache and cookies is a simple step that can potentially resolve the issue.

3. Conflicting Add-Ins

Microsoft Outlook allows users to install add-ins, which are additional software components that enhance the functionality of the application.
