How to Fix Outlook Shared Mailbox Not Updating?

A Shared Mailbox in Outlook is a separate post box that many users in an organization can use to send and receive emails. The Shared Mailbox allows all approved users who approach the Shared Mailbox to timetable and view schedule items. In this article, I will discuss the best ways to resolve the Outlook shared mailbox not updating error.

So, let's start!

Part 1: Basic Information of Outlook Shared Mailbox

In this part, I will give you basic information about Outlook Shared Mailbox. So, let's see.

1. Introduce what is Outlook Shared Mailbox

Most of the time, shared mailboxes are used to communicate with clients because multiple users can track and respond to inquiries. After being added by the administrator as a member of the Shared Mailbox, a user can add a Shared Mailbox.

2. Why the Shared Mailbox Not Updating

The Outlook shared folder not updating issue may have several root causes. Following is a list of some of them:

Cause 1: Users might experience the error as a result of the corrupt OST file.

Cause 2: If the large file size is the cause of the slow OST file update.

Cause 3: When users turn off the auto-update feature.

Cause 4: If Outlook's connections to the Exchange Server are lost.

Cause 5: If users experience an interruption while synchronizing.

These are the causes of the Outlook shared mailbox not updating error automatically that users encounter. Let's move on to learning more about the various causes of the error.

Part 2: How to Fix Outlook Shared Mailbox Not Updating?

The methods to resolve the Outlook shared inbox not updating issue are provided in this part. Follow the steps explained in each method exactly.

#Method 1: Check Server Status

The first method to solve the error of Outlook shared mailbox not updating automatically is to check the server status. This is because exchange servers may occasionally go down due to maintenance or scheduled backups. A bad network connection can also stop Outlook from updating the Shared Mailbox with Exchange Server. So, reconnect to your Wi-Fi network and open a web browser to resolve this.

Check the Outlook web app (OWA) to see if the server is up and running. If you can access your Outlook account through OWA, it means the server is up and running. And there is a problem with your system, the Outlook app, or the Outlook data file, i.e., OST.

Check if Outlook is having trouble synchronizing the Shared Mailbox with Exchange Server. To do so, check your antivirus and firewall settings


#Method 2: Outlook Auto Sync Shared Mailbox

The next method to fix the shared mailbox not updating in Outlook error is Outlook auto sync shared mailbox. Here are the steps to do so:
