Get email from shared mailbox - Invalid Mailbox ID

[Jasong911]

When a new email arrives in shared mailbox it triggers the flow.

I want to get that email data and do things with it, but the step "Get email (V2)" can't find the Mailbox Item Id.

Need help, any ideas?

this was working previously.

It's strange that I get a green light on "when a new email arrives" so it's definitely authenticating to that shared mailbox and registering a new email arrival, but when I try to get email, it fails regardless of my selection of message ID types

Thank you in advance

Hello.

do not use "Get email" but use GRAPH request instead.

[Jasong911]

can  you please point me towards some reference materials?

Thank you.

That got complicated/I'm out of my league quick. I'm excited to learn about graph, but need a solution that's within FLOW's plug and play components, and doesn't require me learning a new technology. 

This was working perfectly in flow, and I can't figure out what's changed.

Dear @Jasong911 ,

>This was working perfectly in flow, and I can't figure out what's changed. 

Are you sure? The action "Get email (V2)" is aimed for getting email from your personal mailbox but not from the shared mailbox.

>...need a solution that's within FLOW's plug and play components...

As far as I know that's just impossible.

If you'll find a way to do that "within Flow" please let me know.

Regards,

Victor

Thank you again for your wisdom... I can see where using Graph could be a game changer.

This was indeed working two weeks ago - with the standard Outlook Get email part. Was that a fluke/happy accident/bug?

Now it seems when I add that outlook web part, I'm getting an authentication issue, and I'm unable to "fix connection". 

could it be an permissions issue with that con

@Jasong911 I am having the same issue since Monday where it started failing and had been running successfully for the last 5 months. I have a step which marks the shared mailbox email as 'Read' using the MessageId of the outlook item and that step has been failing for some reason- Invalid Mailbox Item Id.

Flow team, any help would be appreciated

@sidkasat  and @Jasong911,

forgive me for my being so bored,  but previously you have just exploit the bug.

Here is a citation from the doc:

Shared Mailbox Support

Except for the operations with shared mailbox in their titles, the other operations do not support shared mailboxes as of yet. 

Do you see "shared mailbox" in this title: "Get email (v2)"?  I don't.

@Jasong911 , I noted that you  have used the deprecated action "Get email" instead of "Get email (v2)". It might be a source of the problem.

The same MS documentation recommends:

 As a workaround, you will need to use Invoke an HTTP request action under HTTP with Azure AD connector. When creating a connection for HTTP with Azure AD connector, input text https://graph.microsoft.com/ for both Azure AD Resource URI and Base Resource URL connection parameters. Once created, you can refer to Outlook mail REST API to set URL and optionally the request body to call its shared mailbox APIs. Note that some of the Outlook functions will only be available on beta version of Graph API. HTTP with Azure AD connector is a premium connector and will not be available if you are having free plan of Microsoft Power Automate.

I started getting this same issue starting 4/19.  This flow has been running for 6 months many times a day with no issues.  When a document is received in a shared mailbox I am getting the email and it is throwing the error.

Did you get any other info on this?

[sidkasat]

@SPDevelKMT No currently there is no more info on it. I have just removed the task of marking the email is read in my flow so it doesn't show as Failed. Still waiting to hear back from the Flow team on what changed

Another solution was found on another thread about the same issue. 

Change the password of the shared mailbox itself and create a connection for Outlook Office 365 using that new password. Change any action to use that connection and it'll work. 

[VictorIvanidze]

Hi @jonathanford,

could you please give more details?

As far as I know, a shared mailbox has no any password as it has no  linked account.

[jonathanford]

Sure thing; shared mailboxes do in fact have users attached to them. From admin.microsoft.com you can search for your shared mailbox display name or address and change it from there. That's what I did and it worked beautifully once I added the new connection. 

[VictorIvanidze]

So all you have done is changing the primary address of the shared mailbox? 

Please confirm.

What should I do if I need the old address and do not want to modify it?

[jonathanford]

No, you do not change the primary address of the mailbox. You simply change the password for the user associated with the mailbox itself. This doesn't change delegate access in anyway. 

[VictorIvanidze]

It seems I finally understood. You have changed the password of the user who runs the flow and who has access to the shared mailbox.

If so, please don't be offended but it's not a solution at all.  Imagine this user is your boss 😉

[jonathanford]

Nope; not what I did. For example, you have a shared mailbox called shared@domain.com. With shared@domain.com there's actually a user associated with it. Go to admin.microsoft.com and search for shared, you'll find the user. Click the key and reset the password. You don't have to worry about this interrupting anyone's delegate access to this mailbox. Go to Flow: click Data on the left side then Connectors. Now click New Connection at the top. Search "Outlook" select Office 365 Outlook. Enter shared@domain.com and the password you created and create the connector. Now go to your broken flow and click the three dots beside the failing action and select the new connection you just created.

>For example, you have a shared mailbox called shared@domain.com. With shared@domain.com there's actually a user associated with it.

No sir. The shared mailbox has no linked/associated users.  

>Go to admin.microsoft.com and search for shared, you'll find the user.

Please show me a screenshot where a user exists in "shared". There are only shared mailboxes in my "shared".
