Recently a customer was getting the error code; 0x80070005-0x000004dc-0x00000524 when trying to email ‘sent as’ from a newly created shared mailbox.
After searching online I found a lot of potential solutions like;
– Make sure only Full Access and Full control are set as permissions, do not use sent on behalf aswell.
– Start Outlook in safemode
– Create a new Outlook profile
– Use the OWA
The only thing that worked was using the OWA, but then I saw that ‘Show in global addresslist’ was set to ‘No’. When I changed this to ‘Yes’ it was working again!
I hope this helpes you out and saves you some time.

Thanks so much, You’re awesome this helped me a lot
This is still valid in 2021.
Office 365 Environment. One of our techs deployed a script to Hide any non active OU AD users from the GAL.
The mailbox was a former full user in the non active OU that was converted to a shared mailbox.
Microsoft was no help in troubleshooting this and sending as the shared mailbox worked in OWA but not local Outlooks.
It worked! Thank you for the solution! “Send As” problem was with Outlook and Power Automate and this solves both!
