Hyperlinks Not Working in Excel for Office 365 ProPlus. Excel Details: From your description, I understand the issue is that the hyperlinks in the spreadsheet change when you attach the spreadsheet in an email and send it to others. (if I misunderstand, feel free to correct me.) In the meantime, I would like to confirm the following information to help you do troubleshooting for. The hyperlinks are not working in any desktop email app, viz. Mail, Yahoo, Google, TouchMail. What is more is they do not work in the online versions. Hyperlinks not working when clicking on Outlook 2016 message. There is an inbuilt option in Excel to update Hyperlinks every time the workbook is saved. If these links are updated every time the workbook is saved, chances of the hyperlinks not working is increased. Follow these steps to reinstate the Excel hyperlinks: If you are using Excel 2013, 2016, or 2019.

Many users have reported an issue were they are unable to open hyperlinks sent through email. Upon further investigation, it has been found that the issue was specific to the MS Outlook app and not the mail server.

However, this case could be isolated. Try opening the email through the default browser on your system. If it works well there, then the issue is with the MS Outlook desktop application itself, else it is with the browser or the mail. In case it doesn’t work on the browser either, then try opening it on a different browser or a different system. Try checking other emails which have a hyperlink. Most probably, it should work, unless it is on some unreliable mail server.

The causes behind the issue could be many, so we would troubleshoot it sequentially isolating and removing every possibility of the problem:

1. Search CMD in Windows 10 Search Box and Right Click on it and Run as Administrator

Fix 4] Check issues with the mail server

While this issue has been isolated in the preliminary check, we could discuss it here. If the hyperlink is not working even when we have changed the browser and checked a different email, the issue might be with the email server. A few popular ones like Gmail, Hotmail, etc. are trusted, but many other local companies might offer services without the functionality to open hyperlinks. In this case, the issue cannot be resolved from our end.
