In compose mode, most email programs won't allow you to use the links in your email signature.

I am composing an email and I can't click on any links or social media icons If you use your mouse, you may miss out on some of the vital code needed to make your signature work correctly. Don't use your mouse, only use Ctrl + A (hold the Ctrl button and press A at the same time) to select all of your email signature.

More than likely, you have used your mouse to highlight the html email signature file in the browser. My email signature doesn't look right when I paste it In order for your email signature to work in both the desktop and iPhone/iPad app versions of Office 365, you will need to install it directly into the webmail's settings. The way the browser extension works is that it injects the HTML from your email signature directly into the browser page, it does not save it to Office 365's settings. If I use the browser extension, will my email signature work with the Office 365 iPhone/iPad app? If you experience this issue at any stage, please follow our web extension installation instructions as an alternative. Office 365 used to have a character restriction limit on email signatures, however they have since removed this. I get an error saying my email signature is too long. If you have tried our Instructions or Browser Extension instructions for installing your email signature in Office 365 and you run into any issues, please read through this troubleshooting guide before contacting Support for further help.
