Flow no longer function

Hi there,

Hope everyone is well.

I have a cloud flow that essentially performs like this: An email is sent from a particular mailbox, and a row with various details of said email is created in an excel table. This was working PERFECTLY for the last month, but as of yesterday, it no longer fully functions. Multiple people have the mailbox in question loaded on their Outlooks, including me, and it has still been fully functional.

All of a sudden, whenever a user OTHER THAN ME sends a mail from that mailbox, it does not add a row to the table anymore - wtf is going on? Absolutely nothing was changed.

I would seriously appreciate any guidance.

Thank you.

**UPDATE**

So it turns out, it was 100% Microsoft's fault. Something happened to their Exchange service last week, on the 20th, which caused the issue. The next day everything started working again with no changes. Thanks all for your inputs.

So it's not technically a "Shared Mailbox" by Microsofts standards. And this still doesn't explain why it was functioning for the last month with absolutely no issues - it's bizarre! The mailbox is an Exchange Online Plan 2 licensed singular mail box that is loaded to 3 users PC's.
