An outdated version of Outlook

Possibly the most common reason this error is encountered is because of the version difference. The server may be compatible with an updated version that you may not have installed yet, therefore making your Outlook version outdated. To fix this, allow the software to install an updated version when prompted. If the software does not update automatically and does not prompt updating, consider reinstalling the software.

Clear the cache and all cookies

Another common reason for the error is the cache and cookies in the computer. They are often the cause behind many different errors encountered with web-based applications.  Sometimes, odd behavior has been noticed from Outlook caused by the temporary data held in the cache and cookies.

Log out of other accounts

This one is the first one to look out for if the previous two are not helping. A lack of synchronization between the different accounts can cause this error. And the lack of synchronization can be caused by signing in from too many accounts on this software.

To solve this, simply keep the account you use most logged in. Then sign out from the rest of them. This makes it easier for the software to keep track of all the data linearly. Rather than having multiple sources of data to synchronize.

Use the web version on the browser

The software version that is directly installed on the PC has unique features. While this is true, many errors and bugs accompany it. Be that as it may, the same is not true for the web-based version of the browser. The browser eliminates errors that come along with the desktop version of the software.

This makes it much easier to use the Outlook software and is perhaps the optimum way to use it. For individuals and users who use Outlook on a daily basis, this is the optimum way to use it, especially those who use it for corporate and business purposes. 

Try contacting Microsoft’s support team

If none of the solutions so far have worked, it should be noted that no one understands the Outlook application more than those who made it! There are different ways to contact the support team behind Microsoft. At their contact site, they offer a phone number, which is 1-800-936-5900 according to their website.  that you can call for a voice call.

This may prove to be tedious or cumbersome, as the calls often have a queue. The easiest way to contact them is through their mail, or by using the Get Help Application that comes with Windows. There, you will be prompted to interact with the virtual agent, and later on, if the issue is not solved, a live chat support member will be acquainted with you.

Remove and reinstall the software entirely

This is when you can conclude that the issue that your software is encountering is too vague under the circumstances. The best solution now would be to uninstall the application and delete all cache if they are present on your system. This means that none of the methods above have worked.

And now you will have to sign in to your client newly after having installed it. Tedious as it may be, this is highly likely to solve the issue, as it is with a lot of other web-based software.

Switch to a different mailing client

While Outlook is great, if the issue still cannot be solved, it may be time to let it go. Various other e-mail clients are used widely, across academic, corporate, and business platforms. Thunderbird, Postbox, and Airmail are some great other alternatives to Outlook. If you are a Windows user, it is highly suggested that you try to solve the issue in Outlook, as it is also a Windows (Microsoft) product.

There are some small benefits that you can get with Outlook on Windows just because it is on that operating system. But indeed, if all else fails, consider switching to alternative mailing client software or applications. 


These were some easy solutions to the error [pii_email_c75373ce5b34bf577425] that is encountered on Microsoft Outlook. It may seem like an easy error to fix from the description above, but it can prove to be super inconvenient if users get it frequently. The error can render someone’s ability to send e-mails useless if they are fully dependent on Microsoft Outlook for their daily mailing activities.

With that said, I hope you were able to solve the [pii_email_c75373ce5b34bf577425] error and the issues that were encountered along with it. If none of the steps have worked, it may be effective to consider the last one. I hope you found the steps to be helpful.
