How to Fix Mac Outlook Error Code 19723: Easy Solutions
Mac Outlook is a popular desktop email client among Mac users, widely used as an efficient client-server application. However, like any software, it can encounter some common issues, especially when operating in server environments. Many Mac users report receiving error messages while using Outlook for Mac. These errors usually occur due to mismatches between the application’s settings, network problems, or synchronization issues with the server. Fortunately, such errors can often be resolved manually using straightforward methods. Additionally, this article will introduce a more effective solution to help you fix Mac Outlook error 19723 seamlessly, which is discussed in detail later.
Outlook for Mac is one of the most popular desktop email clients designed by Microsoft specifically for Apple’s macOS. It works seamlessly with various versions of Microsoft Exchange Server including 2010, 2013, 2016, and 2019 making it a reliable client-server application for many users.
However, like its Windows counterpart, Outlook for Mac can experience several well-known issues when connected to server environments.
Whenever an error occurs, Microsoft assigns a unique error code to help identify the problem. One such error is code 19723, which appears when Outlook struggles to sync with the Exchange server. This error can cause you to lose access to your stored data, leaving you unable to send or receive emails. Naturally, this halts your workflow and disrupts business operations wherever Outlook is used.
An example of this problem is the error message: “could not synchronize record Outlook 2011 Mac.”
In this article, I will explain what the Outlook for Mac 19723 error means, what typically causes it, and provide a detailed, step-by-step guide to help you fix the issue efficiently.
What Is Mac Outlook Error 19723?
This error typically occurs when a user migrates emails from another Exchange Server or email client to Mac Outlook 2011 or 2016, and those emails contain calendar invitations. When this happens, Outlook displays the error message “Could not synchronize record” (Error 19723) and may cause the program window to crash unexpectedly.
The fix for this issue is straightforward: you need to locate the migrated emails that include calendar invitations and remove the attachments related to those invites. After deleting the attachments, ensure that you also clear them from the Deleted Items folder, as leaving them there might continue to trigger the error.
What Causes Error Code 19723?
The root cause of this error lies in how the Exchange server synchronizes items with a macOS-based Outlook client. Specifically, during the Move-Item action in the Exchange Web Services (EWS), an incorrect ChangeKey attribute is returned for the moved item. This mismatch leads to the synchronization failure, triggering the Outlook 19723 error.
Microsoft has acknowledged that this synchronization issue affects not just Outlook for Mac, but other related products as well.
Symptoms and Signs of Error 19723
- Your Outlook program window crashes when the “Could not synchronize record” error appears.

- Your Mac experiences significant lag or slow performance.
- Occasional freezing of your operating system.
- Corrupted operating system files can also contribute to this error.
- Running too many background applications can cause Outlook to lag, freeze, or crash.
By understanding these causes and symptoms, you can better troubleshoot and resolve Outlook Mac Error 19723 to restore smooth email synchronization.
