New email in shared mailbox trigger skips messages

I'm getting inconsistent results with the "When a new email arrives in a shared mailbox" trigger. 


The trigger is set to monitor a subfolder of a shared mailbox. When a new message shows up in the subfolder, we want to forward it to an external address. Generally, users are dragging and dropping messages from various other sources to that subfolder. 


The flow works most of the time, but for some reason, it skips some messages repeatedly. The messages are standard emails with small attachments of varying types (usually PDF, Word, and Excel). We're not coming close to the max size limit, and the messages don't have any rights management rules applied to them. 


If I test the flow and choose the Use Outlook 365 Data option while old messages are in the subfolder, the flow successfully processes one of the old messages.

Hi @bwcarty ,

Could you please share a screenshot of your flow's configuration?

I suggest you set 'Include Attachments' Field to 'Yes' for a try.

Re: New email in shared mailbox trigger skips messages

Here's the simplest version. I have a more complex version that has Has Attachments and Include Attachments both set to yes, but they both have the problem with skipping some messages that users drop in the folder.
