If the Add-in is not showing your list of locations and possibly showing an error like the one below... 




...try these possible fixes in the sequence shown.

Method 1: Hit the refresh button


In many cases, a refresh is all that's needed.


Method 2: close and re-open the Add-in


If that didn't work, try closing the Add-in:



...then pick it from the ribbon menu or the waffle menu depending on the platform you are running on. If you can't find the CloudFiler icon, following this guidance: Add-in is not appearing



Method 3: Re-start Outlook

Outlook sometimes fails to respond to all Add-ins and you can test this by trying other Add-ins such as Microsoft's own Viva Insights. If you get the same error shown at the top of this page, close Outlook and re-start it.


Method 4: Clear the cache and force the Add-in to refresh


If the Add-in is running an older version of the software despite colleagues or other devices running the latest version, it's likely to be because the local cache is not clearing. 


To clear the cache you will need DevTools running side-by-side with Outlook - don't worry, you won't need to touch any code.


Right-click over the CloudFiler Add-in and pick 'Inspect' from the menu. This will open DevTools.


Position the Outlook and DevTools windows side-by-side so that they are both visible.


Disable caching

Select the Network tab and then check the Disable cache checkbox


Refresh the Add-in

Next, pick on one of the filing tiles. Nothing will happen but it's important that you do this as we need the next command to be directed to the Add-in.

Next, hold down the CTRL and SHIFT keys on the keyboard and press the 'R' key. 


This forces a refresh. If you did it correctly, the CloudFiler Add-in will re-load and you will see the liquid 'spinner'. If that doesn't happen try the steps above again.


You should now have the latest code and can close DevTools.


Method 5: Delete Outlook's cached folders and install 32-bit Outlook

If that does not resolve the problem. This next method is likely to work.

Outlook maintains cached content in the following two places. You can safely delete these as Outlook will simply re-create them. There also appears to be an issue with 64-bit Outlook. So clearing these caches and then running 32-bit Outlook clears the problem.


  • %localappdata%\Microsoft\Office\16.0\Wef\  
  • %userprofile%\AppData\Local\Microsoft\Outlook\HubAppFileCache


Here are the steps:


  1. Close all Outlook windows
  2. Uninstall Outlook
  3. Open Windows File Explorer and paste in the first path in i.e. %localappdata%\Microsoft\Office\16.0\Wef\  It will look like this:

  1. Hit Return on the keyboard
  2. You should then see a number of files and folders similar to this (they won’t be the same):

  1. Before you delete anything, make sure that the path matches what is shown here:

  1. Select ALL of the files and folders and delete them
  2. Repeat for the other path shown above
  3. Install 32-bit Outlook
  4. Re-start Outlook



Method 6: Clear the Edge Browser cache

If neither of these work, consider clearing the Edge Browser cache.

There may be reasons why you don't wish to do this, so please check with your IT support people.


Steps:

  • Close Outlook
  • Clear the cache
  • Re-open Outlook.


Note that you may need to adjust the Time Range.
