Causes of Outlook error 3399811147

 Failure in Web Account Manager or WAM: WAM, Web Account Manager is the component of Microsoft Outlook responsible for maintaining the connections between the Outlook email client and web-based email accounts on Gmail, Yahoo, etc. It plays a crucial role in handling tasks related to login credential authentication and email data recovery. Synchronization errors like error code 3399811147 can occur if WAM is not working properly due to incorrect email settings, web server issues, etc. Corrupted Outlook data file: An Outlook data file stores information about Outlook accounts including emails, contacts, events, tasks, etc. If the same file gets corrupted due to virus or malware infections, incorrect errors, etc., it can lead to an error. File corruption can prevent Outlook from accessing or processing the stored information, which can result in failure to send or receive mail or synchronize it.

How to Fix Outlook Error Code 3399811147

 Although restarting the system can resolve Outlook error code 3399811147 at times, in case the problem persists, we can follow the steps mentioned below to fix the problem:

•  Repair WAM 
• Create a new user profile
•  Delete Access Work or School 
• Start Outlook in Safe Mode.

1] Repair WAM 

Repairing WAM will help us restore Outlook, thus resolving the said error, with the following steps:

•  Open Windows PowerShell as administrator by searching for PowerShell in the Windows search bar and then clicking Run as administrator.
• If the issue occurs with the worker account, run the following in PowerShell: 

if (-not (Get-AppxPackage Microsoft.AAD.BrokerPlugin)) { Add-AppxPackage -Register "$env:windirSystemAppsMicrosoft.AAD.BrokerPlugin_cw5n1h2txyewyAppxmanifest.xml" -DisableDevelopmentMode -ForceApplicationShutdown } Get-AppxPackage Microsoft.AAD.BrokerPlugin The above command checks if the Microsoft.AAD.BrokerPlugin package is installed and installs it, if not, from the given path.

If(-not - Negates the result of the previous command, making the condition true if the package is not installed. Get-AppxPackage Microsoft.AAD.BrokerPlugin - Checks if the application package named Microsoft.AAD.BrokerPlugin exists. Add-AppxPackage - Installs an application package -Register - Specifies the package path $env:windirSystemAppsMicrosoft.AAD.BrokerPlugin_cw5n1h2txyewyAppxmani fest.xml -DisableDevelopmentMode - Disables development mode for the package -ForceApplicationShutdown - Forces the Outlook application to close while the package is installed If the account is personal, the below mentioned command can be entered and run from the PowerShell command prompt as the package is different for a personal account if(-not (Get-AppxPackage Microsoft.Windows.CloudExperienceHost )) { Add-AppxPackage -Register "$env:windirSystemAppsMicrosoft.Windows.CloudExperienceHost_cw5n1h2txyewyAppxmanifest.xml" -DisableDevelopmentMode -ForceApplicationShutdown } Get-AppxPackage Microsoft.Windows.CloudExperienceHost if (-not (Get-AppxPackage Microsoft.Windows.CloudExperienceHost) ): Checks if the package named Microsoft.Windows. Installing or not CloudExperienceHost uses the –not operator, so the condition is true only if the package is not installed.

Add-AppxPackage -Register "$env:windirSystemAppsMicrosoft.Windows.CloudExperienceHost_cw5n1h2txyewyAppxmanifest.xml" -DisableDevelopmentMode –ForceApplicationShutdown: This command starts the installation of the application package with the name mentioned above from the path $env:windirSystemAppsMicrosoft.Windows.

Since the error is mostly known to occur due to corrupted profile data, outdated settings, or application conflicts, creating a new profile can help reset the profile settings to avoid errors arising from the previous one. So, this step can help restore the functionality of Outlook. To create a new profile in Outlook: Open Outlook and click on File > Account Settings > Manage Profiles Once the Mail Setup dialog box appears, click on Show Profiles In the next window – Mail, click on Add to add an email ID to the newly created profile.
Enter the name and email address, along with the password, twice next to it. Re-enter the password, click on Next to allow Outlook to add the email to the profile, and click on Finish once done.

3] Remove Access from Work or School 

If the above steps do not resolve the issue, we can address the problem by trying to isolate it to a specific account. This approach can help us if the error is specific to a particular account or if the problem is with the Outlook application itself.

Removing access to work or school accounts can also help us isolate the problem and address potential conflicts and sync issues to resolve the issue. To remove the account:

•  ‌Open the Settings app by typing it in the desktop search bar.
•  Navigate to Accounts > Work or school access in Settings to select the account and click Sign out.

• Restart the system and sign in with a local account to check if the issue is resolved.

4] Start Outlook in Safe Mode

 Safe mode allows you to start the Outlook application with minimal add-ins or settings. So, it can help us identify if the issue is due to any add-in or settings conflict.

If the error does not appear in safe mode, we can confirm that the issue is with the add-ins and hence, we can enable the add-ins one by one to identify the particular add-ins causing the problem. To open Outlook in Safe Mode: ‌

• Open Run dialog box by pressing Windows key + R ‌
• Type outlook.exe /safe and click OK to open Outlook in Safe Mode and check if the error appears.
