* Obtain the Message Header: Ask the CEO to provide the full email header of the affected messages.
* In Gmail, this can be done by opening the email, clicking on the three dots in the top right corner, and selecting "Show original".
* Analyze the Header Using Google Workspace Toolbox:
* Go to the Google Workspace Toolbox.
* Paste the email header into the toolbox and analyze it to identify where the email might be flagged as spam and why.
* Email Log Search:
* Log into the Google Admin console at admin.google.com.
* Navigate to Reports > Email Log Search.
* Conduct a search using the sender's email address, date, and other relevant details to trace the message route.
* Analyze the logs to see where and why the message might have been marked as spam.

* Update Active Directory: Since your organization syncs directory data from Active Directory to Google Workspace, any changes to user data need to be made in Active Directory first.
* Change Primary Email in AD: Change the user's primary email address in Active Directory. This will ensure that the new email address is synchronized with Google Workspace.
* Change Last Name in AD: Similarly, change the user's last name in Active Directory. This ensures the updated name is synchronized correctly.
* Sync Changes: Wait for the next synchronization cycle of Google Cloud Directory Sync (GCDS) to update the changes in Google Workspace.
* Verify Changes in Google Workspace: After the sync is complete, verify that the changes to the user's email address and last name have been successfully updated in Google Workspace.
