The specified object was not found in the store - when trying to send an email

[lee-martin]

I'm getting the following error when trying to send an email through PA

The specified object was not found in the store., The process failed to get the correct properties.

clientRequestId: c032f711-b19a-49e5-8e7b-1540ff7d51b8

serviceRequestId: 53ef2436-2edb-9e25-176f-bffa7a2277ab

I'm using "Send an email from a shared mailbox (V2)"

I've set the email to be sent via a service account.

It fails as per the above error message.  However it was working when originally using a personal account to send the emails from (not mine) - this is an update to that functionality  

I thought it might be because I created the flow/solution using my personal account in dev, then uploaded it still using my personal account into Test. I tried creating a new version of the flow using the Service Account account, but that didn't work.

Can anyone point me in the right direction?

Thanks

I've noticed from playing around with a few things, that the Service Account might not be authorised to send emails from the specified mailbox

Could that cause this error?

Error turned out to be the Mailbox not authorising the service accounts to send email

 Was this a setting on the mailbox itself or a tenant level option?

Hi @lee-martin 

It w ould be good if you could post how you authorize the service.

This should be done with each user account (1-1,000,000,000)...wouldn't it be better automatically?

Look this (but don't is enough):

We did not authorize the service, we changed how the flow worked

Hi @lee-martin 

Could you comment, how did you change the flow, maybe some reference (URL) that I could leave and share, to give as a solution to the problem initially indicated.

Thanks

@lee-martin Could you please share how you specifically modified the flow? We continue to see this error even after trying the "copy the flow and run that" solution that had been proposed in other "solutions" listed in the community.
 @v-liwei-msft this really isn't a "solution" as it does not provide details on what the user did to resolve the issue. Is there a way that we can have an actual solution posted please? 
Thanks!

Similar issue. I am the creator of the flow. I am trying to make it so the email comes from a shared box. I have received confirmation from my admin that I now have "send as" permission and when I send an email from the shared box it shows correctly. However, when I create the flow I am still getting this error.

I solved my issue. You cannot set up the flow with the action "Send from a shared mailbox". Instead, set it up with "Send an email". This set's up the flow to send from your own email. Under advance settings you can then choose to to send from the shared email under the "From" field and also set it up to for reply to go to the shared email by putting the email in the "reply to" field. Once I made this change on the actions the flow worked perfectly since I have "Send As" permission.

Go to the M 365 admin center then go to Tems & Groups then Shared mailboxes. 

Click on the shared mailbox name or create one.

On the right side of the panel enable the 'Manage mailbox permissions' and add the user who is connected to the flow.

This worked for me after about 30 minutes after enabling, hope it helps.
