Microsoft Outlook is one of the most widely used applications for managing personal and professional emails. If you receive Microsoft Outlook Error Tag 7ita9, Error Code 3399811147 when using or opening Outlook, here is how to fix the issue.
What does the Error Code 3399811147 in Outlook indicate?
Error Code 3399811147 is a specific numerical identifier used by Microsoft Outlook to indicate synchronization problems with email accounts. The code acts as a reference, helping us determine the exact causes of the problem and the necessary resolution steps.
Causes for Outlook Error Code 3399811147
Fault in Web Account Manager ( WAM): WAM, or Web Account Manager, is a component of Microsoft Outlook that is responsible for managing the connections between the Outlook e-mail client and web-based email accounts in Gmail, Yahoo, etc. It plays a vital role in handling tasks like authenticating login credentials and retrieving email data. Synchronization errors like Error Code 3399811147 may occur if the WAM is not functioning correctly due to incorrect mail settings, web server problems, etc.
Corrupt Outlook Data File: An Outlook data file stores information about Outlook accounts, including emails, contacts, events, tasks, etc. If the same file is corrupted due to virus or malware infections, improper shutdowns, etc., it can lead to an error. File corruption can prevent Outlook from accessing or processing stored information, failing to send or receive mail or synchronize it.
Incompatible Add-ins: Outdated, improperly installed, or conflicting add-ins may lead to slow performance and data corruption and can stop Outlook from performing its core functions. Such problems may appear as specific error codes, including those.
How to fix Outlook Error Code 3399811147
Although restarting the system may resolve the Outlook Error Tag 7ita9, Error Code 3399811147 at times, in case the problem persists, we can follow the below-mentioned steps to troubleshoot and resolve the issue:
- Repair WAM
- Create a new User profile
- Remove Access Work or School
- Start Outlook in Safe Mode.
1] Repair WAM
Repairing the WAM can help us restore Outlook, thereby resolving the said error, by following the below-mentioned steps:
- Open the Windows PowerShell as an Administrator by typing PowerShell in the Windows Search Bar and then clicking Run as Administrator.
- If the issue is encountered about a work account, run the below-mentioned command in PowerShell:
if (-not (Get-AppxPackage Microsoft.AAD.BrokerPlugin))
{ Add-AppxPackage -Register "$env:windir\SystemApps\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy\Appxmanifest.xml" -
DisableDevelopmentMode -ForceApplicationShutdown } Get-AppxPackage Microsoft.AAD.BrokerPlugin
The above command checks whether the Microsoft.AAD.BrokerPlugin package is installed, and install it if it isn’t from the specified 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 whether the app package is named Microsoft.AAD.BrokerPlugin exists.
Add-AppxPackage: installs an application package
-Register: specifies the path of the package $env:windir\SystemApps\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy\Appxmanifest.xml
-DisableDevelopmentMode: disables the development mode for the package
-ForceApplicationShutdown: forces the Outlook application to close while the package is installed.
- If the account is personal, the below-mentioned command can be entered and executed from the PowerShell prompt since the package is different for a personal account.
if(-not (Get-AppxPackage Microsoft.Windows.CloudExperienceHost)) { Add-AppxPackage -Register "$env:windir\SystemApps\Microsoft.Windows.CloudExperienceHost_cw5n1h2txyewy\Appxmanifest.xml" -DisableDevelopmentMode -ForceApplicationShutdown } Get-AppxPackage Microsoft.Windows.CloudExperienceHost
if (-not (Get-AppxPackage Microsoft.Windows.CloudExperienceHost)): checks if the package named Microsoft.Windows.CloudExperienceHost is installed or not using the –not operator, so the condition is true only if the package is not installed.
Add-AppxPackage -Register “$env:windir\SystemApps\Microsoft.Windows.CloudExperienceHost_cw5n1h2txyewy\Appxmanifest.xml” -DisableDevelopmentMode –ForceApplicationShutdown: Initiates the installation of the application named above package from the path
$env:windir\SystemApps\Microsoft.Windows.CloudExperienceHost_cw5n1h2txyewy\Appxmanifest.xml and disables the development mode after shutting down the Outlook application forcibly during the installation process.
2] Create a new profile
Since the error is known to occur primarily due to corrupted profile data, outdated settings, or application conflicts, creating a new profile can help re-initialize the profile settings to avoid errors arising from the old one. Hence, such a step can help in restoring Outlook’s functionality. To create a new profile in Outlook:
- Open Outlook and click on File > Account Settings > Manage Profiles
- Once the Mail Setup dialogue box comes up, click on Show Profiles
- In the Mail window that comes up next, click on Add to add an email ID to the newly created profile.
- Please enter the Name and mail address, along with the password, twice beside it. Retype the password, click Next to allow Outlook to add the email to the profile, and click Finish once you’ve done so.
3] Remove Access work or school
If the above steps fail to resolve the issue, we can approach the problem by trying to isolate the issue to a specific account. This approach can help us if the error is specific to one 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 issue and address potential conflicts and synchronization problems to resolve the issue. To remove the account:
- Open the Settings app by typing it on the Desktop Search Bar.
- Navigate to Accounts > Access work or school under Settings to select the account and click on Disconnect.
- Restart the system and login with a local account to check if the issue has been resolved.
4] Start Outlook in safe mode
Safe mode allows the Outlook application to be launched with minimal Add-ins or settings. Hence, it can help us identify if the problem is due to any add-in or settings conflict.
If the error doesn’t appear in safe mode, we can confirm that the problem is with Add-ins, and therefore, we can enable the Add-ins one by one to identify the particular add-ins causing the issue. To start Outlook in safe mode:
- Open the Run dialogue box by pressing the Windows+ R key
- Type outlook.exe/ safe and click OK to start Outlook in safe mode and check if the error is coming up.
I hope the post helps to resolve the issue.
What is the error code correlation ID for Outlook?
To fix the Outlook error with a correlation ID, locate the error in the Outlook logs, typically accessible via Exchange admin or Office 365 admin center. You can then use the correlation ID to identify the issue, which could be related to authentication, permissions, or connectivity, and troubleshoot accordingly.
Is it safe to clear Outlook cache?
Clearing the cache in Outlook doesn’t affect your emails and contacts. It just makes Outlook fetch new information from the internet instead of using stored data on your computer. Any needed files will be saved again after you clear the old ones.
