Flow triggers but Forward an email fails (BadGateway)

(0) ShareShare

Posted on by 2

​​​Hi, I’ve set up a Power Automate flow but I’m having an issue with the forwarding step.

What I’m trying to do: monitor a shared mailbox (acc@_______.co.uk), when a new email arrives with “Expense” in the subject, automatically forward it to my email.

Flow setup: Trigger = When a new email arrives in a shared mailbox (V2), Mailbox = acc@_______.co.uk, Folder = Inbox, Subject filter = Expense.

Action = Forward an email, Message Id = from trigger, To = my personal email address.

Issue: the flow does trigger but the Forward an email step fails with BadGateway.

What I’ve checked: flow is turned on, trigger is correct and detecting new emails, Message Id is populated, I can access the shared mailbox in Outlook.

Question: has anyone seen this before? Could it be permissions on the shared mailbox or an Outlook connection issue? Any help would be appreciated, thanks! 👍

    In this action there is an optional "Original Mailbox Address" field that becomes mandatory when working with shared mailboxes. In the "Original Mailbox Address" field, enter the shared mailbox address (e.g., acc@_______.co.uk) and try again. 
     
     
    Let me know if it worked!
