So, let’s get started!

How to Fix [pii_email_e7ab94772079efbbcb25] Error?

There are a few methods that you should try if you are facing the [pii_email_e7ab94772079efbbcb25] error on your Microsoft Outlook client. Here are the methods that you can try:

1. Try Deleting the Other Accounts:

It’s a common scenario where people start getting [pii_email_e7ab94772079efbbcb25] error pop-ups if they use more than one email accounts in their Microsoft Outlook client. In fact, they may also face this if they’re using only one account from any email service provider other than Microsoft. 

If this is the problem that’s causing the [pii_email_e7ab94772079efbbcb25] error on your Microsoft Outlook client, then you should try deleting all the other accounts while keeping only the Microsoft email address active. This is supposed to solve the problem. 

However, we understand that taking this step beats the very reason behind using Outlook in the first place. If you’re intent on using multiple email addresses from one place, we highly recommend switching to the online client/ website version of Microsoft Outlook. In this way, you’re not supposed to face any [pii_email_e7ab94772079efbbcb25] error no matter how many accounts you connect to Outlook. 

2. Clean the Cookies and the Cache Files:

Do you know what the purpose of the cookies and the cache files are? These are files that are created during the first time you run an application, and these are actually the temporary files that you need while running that application.

Although these are meant to be temporary, the software is designed in such a way that some of the temporary files will be stored in your hard disk drive as permanent files. Due to this, no matter when you use the app, it won’t have to build the temporary files over again, ultimately speeding up the process. 

However, sometimes the cookies and the cache files may contain damaged and corrupt files. In such cases, the applications fail to run properly as they keep on resorting to the corrupted cache files. This is also one of the reasons why you may be facing the [pii_email_e7ab94772079efbbcb25] error. 

The solution to this would be to find out the cache files and cookies. Once you find them, make sure that you delete them. Before doing so, you need to turn off the application completely. Sometimes, the application keeps on running in the background even if you close it completely. In such cases, you will see a pop-up that windows can’t delete the files because they’re already in use. 

Open the task manager, and you’ll find that application to be running as a background process. Select it and make it stop working, and then you’ll be able to delete those files. Make sure you delete only the cache files and nothing else.

You don’t need to back up the cache files, as the software will be able to reproduce them once they’re missing. This is why the software might take a bit more time to run for the first time after you delete all the cache files. 

3. Use the Repair Tool:

If none of the methods mentioned above are working for you, then there’s something wrong with the application settings of your Microsoft Outlook client. In this case, there’s no alternative to repairing the client manually.

This is a comparatively easy process. You need to access your control panel first. You will find the control panel button on the bottom left of the screen. It will pop-up right above the Windows button if you tap the windows button. 

Once you go there, you need to select the view as category mode. If you’re using Windows 10, you’ll need to click on the Apps section. After that, click on the programs section. Here, you can find Microsoft Office 365 or Microsoft Outlook from the provided list. 

Click on it, and then the modify button will appear. Click on the modify button and click on online repair. Once you do this, the software will update and repair itself, and this will fix the problem for good. 


These solutions are supposed to work for you, as they work for most people. However, if you’re facing the rare case where these aren’t working for you, you need to contact the support team of Microsoft immediately, and they will surely provide good feedback that works for you. Hopefully, you’ll be able to get rid of the [pii_email_e7ab94772079efbbcb25] error of Microsoft Outlook with these suggestions.
