How to fix the error Outlook not updating inbox automatically?

Here is a comprehensive list of possible causes for the error ‘Outlook inbox not updating’ and how they can affect the working of Outlook.

1. Slow or unstable internet connection: If your internet connection is slow or unstable, it can prevent Outlook from connecting to the server and downloading new emails. This issue can cause Outlook to stop syncing emails and updating the inbox.
2. Outdated Outlook version: If the Outlook data file is moved or deleted from its original location, Outlook may not be able to find and access it, resulting in the error message. This can happen if the user accidentally moves or deletes the file, or if the file is moved by another program or process.
3. Corrupted Outlook profile: If your Outlook profile is corrupted, it can prevent your inbox from updating. You can try creating a new Outlook profile or rebuilding the OST file in Outlook to fix the issue.
4. Incorrect email account settings: If Outlook is not connecting to the Exchange server, your email account settings are most likely incorrect, which can prevent Outlook from updating the inbox. Check that your email account settings are correct and up to date.
5. Large mailbox size: Sometimes, conflicts with other programs or add-ins can cause the error message. For example, antivirus software, backup software, or third-party add-ins may interfere with Outlook and cause the data file to become inaccessible.
6. Full storage device: If the Outlook profile is corrupted or misconfigured, the application may fail to access the linked data file, leading to error messages. This can occur if the profile settings are accidentally changed or deleted, or if the profile becomes damaged due to software issues or unexpected crashes.
7. Corrupted Outlook data file: If your Outlook data file (OST) is corrupted, it can prevent your inbox from updating. You can try repairing the corrupt OST file or creating a new data file to see if this fixes the issue.
8. Antivirus software: If the user upgrades or downgrades the version of Outlook, it may cause compatibility issues with the data file, resulting in the error message. This can happen if the user upgrades to a newer version of Outlook that is not compatible with the data file format or if the user downgrades to an older version of Outlook that cannot read the data file.
9. Firewall settings: If your firewall settings are blocking Outlook from connecting to the server, it can prevent your inbox from updating. You can try temporarily disabling your firewall to see if this fixes the issue. If it does, then you may need to configure your firewall to allow Outlook to connect to the server.
