[Solved] Emails showing in Outbox on the server but not visible in Outlook user’s Outbox?

Summary: Is your local Outlook folder empty, though you have emails in the Outlook server? Read on to know more about, "There are emails showing in Outbox on the server but are not visible in the user Outbox in Outlook client" error, including its causes and possible solutions.

Bugs and issues are common in software, and Microsoft Outlook is no exception. While some of the Outlook errors stem from the software itself, many errors occur due to lack of system resources or external factors.

In this article, we’ll talk about an issue, “There are emails showing in Outbox on the server but are not visible in the user Outbox in Outlook client.” This indicates that the user has emails stored on the Exchange Server but the local folder is showing empty when clicking on the email view in Outlook Client.

Reasons for the User Outlook Outbox not showing Emails Issue

Let’s take a look at the possible causes for this issue.

• Synchronization Issues

A likely cause of this problem is poor or no synchronization between the server and the client. As a result, the client does not download emails and other content from the server.

• Conflicting Applications

Another potential cause of the problem is the presence of applications like antivirus that can conflict with Outlook. Such applications can hinder Internet connection or data transmission, thereby resulting in discrepancies between the local cache and the Exchange Server.

• Low Storage

If your device is low on storage, emails will not be downloaded from the Exchange Server in the local OST file. Therefore, it’s important to have enough space on the local disk for downloading large chunks of email and attachments from the Exchange Server.

• Oversized Local Cache

Sometimes, the local file (OST file) where Exchange downloads all emails for offline use can become oversized, especially if you’ve been storing thousands of emails with attachments. Such oversized files can become corrupted or inaccessible. This could prevent you from accessing your emails.

Solutions to Fix the Issue

Disable the Antivirus Program

If the antivirus software is the cause of the problem, consider disabling it temporarily. Then, try to download the emails. However, make sure to enable it back after Outlook downloads the emails. You can also check for settings and configurations allowing Outlook to access messages while the antivirus is running.

• Locate the OST file. You can find the location in the Advanced tab of Outlook’s Account Settings.
• Copy the OST file to a different location and then delete it.
