How to Stop TokenFactoryIframe Downloads from Outlook

How to Stop TokenFactoryIframe Downloads from Outlook

The problem concerns users of the online office applications, although there is no official patch yet, you can answer the problem yourself. […]

Users of Office 365’s online applications may experience annoying and frequent downloads of a file called TokenFactoryIframe when accessing their account through a web browser. While Microsoft hasn’t released a solution yet – and it’s not the first time this has happened either – there is a way to stop the downloads.

According to users in a Microsoft support forum (English), the problem mainly occurs with Safari on Mac, but it can also affect Chrome and Firefox on Mac, iPhone or iPad. Since the problem occurs with multiple browsers and platforms, this could mean that it is a problem with Outlook that Microsoft needs to fix.

According to a post by a Microsoft representative, the company is doing research on its page to see if it can find relevant information on this issue.

The temporary solution is to stop the downloads for Office 365. The problem with this solution is that it blocks all downloads. For example, if you use Outlook for e-mails and want to download an attachment, you cannot download it until you change the setting again to allow downloads.

Below are steps to pause downloads in Safari and Chrome.

How to stop Office 365 downloads in Safari for Mac

  1. In Safari, click on the “Safari” menu at the top, and then select “Settings”.
  2. Select Websites.
  3. In the General column on the left, select Downloads.
  4. A list of sites with download permissions will appear in the window on the right. Search for and in the right pop-up menu, select the Refuse option. (If you select the Allow option, a pop-up menu will constantly appear asking you if you want to download the file. With this problem, a download is requested every few minutes).
  5. Close the program settings.

Attention: This will stop all Outlook downloads. So, if you want to retrieve a file from an email, you need to temporarily re-enable the downloads.

How to stop Office 365 Downloads in Chrome for Mac

  3. When you in the See Current Activities section, click on it. If not, click View Permission and Data storage for all sites, and then click .
  4. When you click on click, it should expand. Search for and click on the arrow on the right.
  5. A list of permissions is displayed. Look for Automatic downloads and select the Refuse option in the pop-up menu.
  6. Close the program settings.

What is a TokenFactoryIframe file?

iFrame is a method used by websites to display content. For example, an iFrame is often used when embedding a YouTube video into a website.

It is a widely used item, although it is not known why Office 365 automatically downloads the TokenFactoryIframe file. This file has a size of zero kilobytes and does not seem to have any content.

It could be an error in the HTML code of the Office 365 website and is very likely not malicious.
