Select an email from your inbox, then pick the CloudFiler button on the ribbon menu. This will open the CloudFiler menu in Outlook.

If you can't see it. The first thing to do is select an email and then pick the waffle menu from the head of the preview:

NOTE: New Outlook and Outlook Web Access can fail to remember the pinned state of add-ins. So even though you have pinned it, when you next run Outlook the add-in has gone. If that happens just follow the steps above to re-enable it.


NOTE: The Add-in to Outlook only works with Microsoft Exchange email accounts. So it should work fine with most school, college and university accounts as well as your business account, but won't work with other email servers such as Gmail


WARNING: If you have added a business email account to a virgin installation of Outlook, the Add-in will not appear until you then close and re-start Outlook


Desktop Outlook - Add-in frame appears but content is blank

For reasons best know to Microsoft, even though the Add-in is a small block of code, the first attempt to run an Add-in can lead to it being partially loaded. Leave it for 2-3 hours then re-start Outlook. It should then load as normal and will be fine thereafter.


Mobile phone - extreme case

If your phone has an expired SIM card, the Add-in will not load. Replace the SIM card with one that you know works or remove it completely, whilst ensuring that the phone has a data connection via wi-fi.



Is your Outlook up-to-date?

Most people will have Outlook set to automatically install updates but if you have turned this off you may need to update Outlook to gain the support for Add-ins. To do this:


  1. Click File on the pull-down menu: 

  1. At the bottom of the sidebar menu, click Office Account and then the Update Options button:

  1. Select the option that best meets your needs and once Outlook has updated, close and re-start it, then try to run CloudFiler again.


CloudFiler still not showing in Outlook desktop?

The CloudFiler icon will normally appear automatically but if it hasn't appeared within a sensible period, you can find it by selecting All Apps from the Outlook ribbon menu,

 then select Add-Apps,


from the menu on the left select Built for your org and then CloudFiler

Then pick Open




No Add-ins are showing

We have seen situations where Outlook is not showing any Add-ins including Microsoft's own Viva Insights. These were caused by the customers' firewalls blocking a specific Microsoft.com URL.


You can test whether the URL is blocked by pasting this URL into a browser:


https://titles.prod.mos.microsoft.com/config/v1/environment


If it's contactable it will respond with:


{ "statusCode": 401, "message": "Unauthorized" }


Otherwise you will get an error as it will timeout.


The solution was to unblock the URL at the firewall.
