How to Fix the Missing Email Issue for an Exchange Account on Mac?

Shortly after the release of macOS High Sierra, many users started reporting issues with their Exchange accounts. Specifically, after setting up and synchronizing a Microsoft Exchange account, a considerable number of Mac aficionados have noticed that their mailboxes are empty. Those who do have messages in their mailboxes sometimes cannot see their content, which defeats the purpose of having an Exchange account in the first place.

The aim of this article is to help Mac users to resolve this vexing problem by trying one out of three easy-to-follow solutions.

Rebuild Your Mailbox

Sometimes, Apple Mail fails to either receive or properly display messages. In such cases, it might be helpful to rebuild a mailbox, thereby deleting those messages that are stored on your Mac and downloading them from the Apple mail server. To conduct this easy operation, it is necessary to:

  1. Open Apple Mail and click on the Inbox icon;
  2. Click on the Mailbox tab at the top of the app’s window;
  3. In a drop-down menu, choose the Rebuild

Note that it takes some time to download your messages from the mail server. The more messages you have in your mailbox, the longer it will take to restore them. Also, the mailbox will be empty until all messages are transferred from the server.

Refresh Your Mailbox

Upon verifying the presence of incoming messages via another email account or an iPhone, it possible to make sure that they can be seen in your mailbox by simply refreshing Apple Mail. To this end:

  1. Open Apple Mail and click on the Inbox icon;
  2. Click on the Mailbox tab and select the Take All Accounts Offline option;
  3. Wait fifteen seconds and restore the mail flow by selecting the Take All Accounts Online option in the same tab.

This surprisingly easy fix should resolve the issue with missing mail immediately.

Switch an Email Account

Some Mac users have multiple email accounts that are synchronized with Apple Mail. Even though it is extremely convenient to have several mailboxes for both professional and personal purposes, their ownership can be accompanied by the pesky missing mail issue. The problem is especially pronounced for those who have upgraded their Macs to macOS High Sierra. To restore the proper mail flow, try using an email account other than Exchange. Add the new account to Apple Mail and follow these steps:

  1. Sign in to your preferred email account and click on the Inbox icon;
  2. Once the Inbox folder is opened, quit the application;
  3. Restart the mail app and switch to your Exchange

By simply switching between email accounts, it is possible to remove mail flow bottlenecks, thereby ensuring that no important message is missed.

Update Mac Software

If the issue persists, consider installing the latest software updates on your Mac computer. To this end:

  1. Open the App Store;
  2. Click on the Update tab in the toolbar;
  3. Find Apple Mail;
  4. Use the Update button to install the latest update.

Remove Excessive Messages

An overwhelming amount of messages can prevent you from receiving email via an Exchange account. It is recommended to keep under 5,000 messages in an email account provided by Microsoft.

Disable Automatic Detection of Account Settings

Once in a while, automatic detection of account settings in Apple Mail can disrupt the normal flow of messages. It follows that by disabling this feature, it is possible to fix the missing mail issue that bothers Microsoft Email users. All that needs to be done is to:

  1. Open Apple Mail;
  2. In the Mail menu, select Preferences;
  3. Go to Exchange Account;
  4. In a window that opens, click on the Advanced tab;
  5. Disable the feature by unchecking a box next to the Automatically detect and maintain account settings entry;
  6. Restart Apple Mail.
