Daniel’s User Query:

Today, when I was checking emails to see if there was any important work-related email, I found that there were only 580 emails present in the desktop view. Whereas, in the web view of the same application (Outlook), there were 1000+ emails present. Then, I learned that this discrepancy will be removed if I fix Outlook not showing all emails issue. I have no idea about the entire problem; how can I resolve this problem?

Introduction: IT administrators rely heavily on Outlook every day – for checking support emails, contacting staff members, resolving issues within their Outlook profile settings, and more.

Symptoms of Outlook Not Displaying Emails and Their Causes

There are a few signs that the administrator notices when they use MS Outlook. These symptoms may be triggered due to various reasons that are tabulated below.

Symptoms	What Does It Trigger
New emails are not getting shown in the Inbox	Outlook might not have synchronised the latest changes, or any applied filter is hiding the messages.
Older emails are missing from the Inbox list	Offline synchronisation settings, filters, sorting, or a changed inbox view can affect which messages are displayed.
Emails appear in Search but not in the Inbox	Messages might actually be located elsewhere – perhaps in some other folder, or even hidden from your inbox right now due to a filter or view preference.
Emails appear in Outlook on the web but not desktop Outlook	The desktop application may have a synchronization, cache, profile, or local data-file issue.
Emails are getting shown in the Other folder	Your inbox splits your emails into two categories – ‘Focused’ and ‘Other’ – based on their priority (a highly focused message could occasionally end up in the ‘Other’ section).
Emails are found in another folder instead of the Inbox	Outlook rules, Sweep, junk e-mail filtering, archiving, or even a manual action might have moved your messages elsewhere.

How to Fix Outlook Not Showing All Emails in Inbox?

There are multiple troubleshooting methods to determine the exact cause of the problem and then resolve it via certain steps. In this section, you will explore the native methods to resolve the issue, and if nothing works for you, a dedicated tool to repair the corrupted PST file is discussed as well.

Method 1: Remove Inbox Filters

Microsoft Outlook folder filters can be a direct cause of items appearing to disappear from an Outlook folder. You might have applied a filter and hidden the emails based on the date received, read/unread status, sender/recipient, importance, and size. This might lead to seeing certain emails in Outlook.

Simple Steps to Remove Inbox Filters

Open the affected Inbox in MS Outlook.
Select Filter and choose All to clear the current message-list filter.
In classic Outlook, select View > View Settings > Filter.
Review the Tasks, More Choices, and Advanced tabs.
Clear conditions that may be excluding messages and select OK.
Check the Inbox again.

Method 2: Check for Emails in Both Focused & Other Tabs

When a user receives an email message, Outlook places the email either in the Focused Inbox or under the Other tab. This separation is based on the importance of the message. So if you don’t find a message under the Focused tab, better to check it under the Other tab.

Steps to Fix Outlook Not Showing All Emails

Open Microsoft Outlook and open the Inbox.
Select the Other tab.
Search for the missing email.
If your email message is present incorrectly, select the message and choose Move to >> Move to Focused Inbox.
To have a single Inbox list, change the Focused Inbox setting in Outlook’s Mail/Layout settings.

Method 3: Check Junk, Archive, and Deleted Items

Your email might not show up in your inbox – perhaps it’s been marked as spam, archived, deleted, or relocated to a different folder. Microsoft does suggest looking at Junk Email, Other, Deleted Items, and some other folders whenever an Outlook.com message seems to have been deleted.

Steps to Check Junk, Archive, and Deleted Items:

Open Junk Email and search for the message.
If it is legitimate, move it to Inbox or use the available Not Junk option.
Check the archive and other folders.
Open Deleted Items and search for the message.
Move a recovered message back to Inbox.

Important: Microsoft says that Outlook.com will automatically delete messages from Junk Email after 30 days – and once deleted, they’re lost forever from that folder.

Method 4: Review Outlook Rules

Outlook rules can automatically move incoming messages to another folder. Microsoft also identifies Sweep rules as a possible reason Outlook.com messages are moved away from the Inbox.

Steps to Review Outlook Rules:

Open Microsoft Outlook and proceed to the Settings option.
In the left pane, click on Mail >> then Rules.
Review rules that move, delete, or archive messages.
Identify any rule matching the missing emails.
Edit or delete the rule as appropriate.
Check the Inbox for new messages.

Method 5: Check Sorting and Conversation View

A changed message-list arrangement can make emails difficult to locate. Your messages might be sorted on the basis of date, sender, size, importance, subject, and category. Even in the Conversation View, the related messages can be grouped together.

Steps to Cross-Verify the Sorting & Fix Outlook Not Showing All Emails

Open Microsoft Outlook on your system and open the Inbox.
Check the current sorting option.
Sort by date to review messages chronologically.
Review whether Conversation View is grouping related messages.
If using classic Outlook, review the folder’s View Settings.

Method 6: Sync Outlook and Check the Connection

There might be a synchronisation problem that stops messages from being displayed in the mailbox or New Outlook not showing old emails. In classic Outlook, labels like ‘Disconnected’ or ‘Working Offline’ show that the Outlook application is not working properly.

Steps to Sync Outlook are as follows:

Confirm that the device has an active internet connection.

In classic Outlook, open Send/Receive.
If Work Offline is enabled, select it to reconnect.
Select Send/Receive All Folders.
Wait for synchronisation to complete.
Reopen or refresh the Inbox and check the missing messages.

Method 7: Check Offline Mail Settings

New Outlook has offline settings that control which mail is available when working without an internet connection. Microsoft states that the default “Days of email to save” window was expanded from 7 days to 30 days. This setting should not be described as an email-deletion limit; it concerns offline availability.

Steps to Check Offline Mail Settings:

Open Settings in new Outlook.
Select General > Offline.
Review the offline folders and days of email to save setting.
Adjust the setting if the required older messages are not available offline.
Reconnect to the internet and allow Outlook to synchronize.

Method 8: Repair the Corrupted PST File Using ScanPST.exe

Your lost emails stored in PST format might be kept in a file that’s corrupting itself. To fix it, you can use ScanPST, also known as the Inbox Repair Tool. It is highly recommended to first have a backup of the original PST file and then only look to repair it.

Steps to Use the ScanPST Tool:

Close Outlook completely.
Locate and open SCANPST.EXE. In supported current Outlook installations, Microsoft lists the Office16 folder as a typical location.
Select Browse and choose the affected .pst file.
Select Start to scan the file.
If errors are detected, select Repair.
Keep the option to create a backup of the original PST before repairing.
Open Outlook after the repair finishes and check the affected folders.
If necessary, run SCANPST again because Microsoft states that multiple repair passes may sometimes be required.

When users ask, “My Outlook Not Displaying Email Body Content”, the issue might be occurring due to the inaccessible PST file only. If you have followed the above steps, your issue has been resolved.

What Happens After Repair?

Microsoft notes that Outlook may create Recovered Personal Folders and Lost and Found folders. Items that SCANPST cannot associate with their original folder may appear in Lost and Found. The tool also creates a .bak backup file that can potentially be used to recover additional items.

Technical note: SCANPST repairs the PST data structure; it does not connect to or analyse data stored directly in an Exchange mailbox. Therefore, it should not be presented as a general solution for every “Outlook not showing emails” situation.

Frequently Asked Questions

Q1. Why are emails visible in Outlook on the web but not in desktop Outlook?

Ans: Sometimes, it might happen that when you check emails in Outlook on the web and the desktop version, the total number of emails appearing is different. This issue might take place due to a synchronisation issue, there being some cached data, filters being applied, or local data files. You just have to compare both application versions and look for the difference in the email volume to detect this issue.

Q2. Can a corrupted PST file cause Outlook to stop showing emails?

Ans: Yes, if the missing emails are stored in a damaged PST file, corruption can affect access to mailbox data. Microsoft’s Inbox Repair Tool (SCANPST. EXE) will scan your PST file for any errors and fix them when it finds a problem. If this tool doesn’t work well, you can use the Aryson Outlook PST Repair tool for the same.

Q3. Why is Outlook not showing emails from a specific sender?

Ans: If there is just a particular sender whose emails are not being shown, check if the sender’s emails are moved to another folder or have been filtered from the Inbox itself. You can search for the sender’s email address and check the Junk Email, Archive, Deleted Items, and Other folders to find the emails.

Q4. Why is Outlook only showing emails from the last 30 days?

Ans: If you are unable to see recent emails in Outlook, check the offline settings and check whether there is any limit to how much data can be stored locally. In the New Outlook, check Settings >> General >> Offline and cross-verify the Days of email to save option. If you increase the available offline period, your older messages will appear in Outlook.

Q5. Why are emails missing from Outlook after changing the account password?

Ans: When you change your password, for security purposes, Outlook needs to authenticate the account again with the new credentials. Now, if the account is not properly synchronised, some emails may not be shown in the desktop version. Sign in again with the new password and check if the issue is resolved or not.

Q6. Does Aryson Outlook PST Repair Tool maintain the original PST folder hierarchy?

Ans: Yes, the Aryson Outlook PST Repair Tool maintains the original PST folder hierarchy during the recovery process. This eventually helps users to preserve the existing folder structure when the recovered mailbox data is saved.
