What Causes Outlook Error [pii_email_e7ab94772079efbbcb25]?
Outlook has been installed on your computer without any problems. But after several months, you start getting this error. This usually happens when you install new software on your PC. It may happen because of a virus infection or a malware attack.
You should check if there is any suspicious program running on your system. If you have recently updated your antivirus, then make sure that it is up-to-date. Also, try to scan your entire system with an anti-malware tool.
If you suspect that the installation of your Outlook application has been corrupted, you should reinstall the app and see if the error still occurs.
Multiple Accounts on Microsoft Outlook
Occasionally, Outlook does not allow you to open multiple accounts at once.
For example, if you want to use a Gmail account along with a Hotmail account, then you need to close one of them first. Then re-open both of them again. This may solve the problem.
Unable To Connect To Server
You might be facing issues while connecting to the server. In this case, you should check if you have entered the correct information correctly. Make sure that you have typed the right name of the server and its IP address. Also, make sure that you have selected the correct port number.
Other Application Confliction
It is possible that you have another application running on your PC which conflicts with the Outlook application. So, simply remove this application and restart your PC. After doing that, try opening Outlook again.
This error can also occur due to corruption in the cache folder. If the browser stored cache becomes corrupted, this may interfere with running applications. So, delete the cache files from the C:\Users\[username]\AppData\Local\Microsoft\Outlook folder. Restart your PC and try opening Outlook again. If the error persists, then you will have to perform a clean installation of the application.
Temporary Internet Files
The temporary internet files can cause this error. Delete these files and restart your PC. Try opening Outlook again.
In rare cases, you may face an issue with the Internet connection. So, try checking whether the network cable is connected properly. Also, make sure to check for any firewall settings.
Outdated Microsoft Outlook Version
