Hi All. Thanks in advance for your help.

We're having an issue with notification emails not "loading" in Outlook for desktop on Windows. Has anybody else experienced this?

Here's a screenshot https://prnt.sc/1v1gzmx

Notification emails work fine when opened with other clients: Gmail, Outlook online, Outlook on phone, Outlook on Mac. But when I or my clients open the notification emails in Outlook desktop for windows, the email is blank with animated loading dots at the top of the email. 

The notification is the default notification email. My clients and their IT and I can't open these emails, and we've all got different receiving email services. The one thing in common is that we are all using the same client to check the emails. 

I tried support and they weren't able to solve this. I can't imagine I'm the only person who has experienced this issue. Any tips to troubleshoot would be appreciated.
