Hey guys. Anyone having problems with using shared mailboxes in their flow?
Specifically the user does not receive any email from the shared mailbox, and then the flow would fail with the error "Specified Folder not found"
See the screenshot:
flow Error 
Approval Flow
After approval, the user should receive an email notifying that the request has been approved. It is sent from a shared mailbox.
I've read a similar post here.
https://powerusers.microsoft.com/t5/Building-Power-Apps-Formerly/Specified-folder-not-found/td-p/162424
It says the user is SENDING from the shared mailbox. But for me, the user is RECEIVING from the shared mailbox.
I've tested several things before posting:
1. Changed the user permission in the sharepoint list to full control
2. Created similar flow with same process to test the approval
3. removed user permission in sharepoint and add the user again with full control
4. removed permission in powerapps and add the user again
5. Gave full access to user in shared mailbox
Edit:
We tested it with two users. They have the same Office 365 license. One user does receive the email from shared mailbox, but the other does not.
We have both added them to have full access to the shared mailbox. Anything else we can check on these users?
I've done the things above and still the user cannot receive email from shared mailbox, and then the flow would fail.
Anyone have ideas?
Much appreciated, thanks!
