Scenario: Organization has throttling policy with recipient
rate limit of 10,000 per day set for the organization. For this org, service
mailboxes aren't throttled. User has 2 mailboxes (primary and service mailbox)
opened in Outlook. User has send-as permissions to the service mailbox but as a
group member.
User tries to send from outlook as service mailbox to
multiple recipients but received error message. see error message below
Undeliverable: your message did not reach some or all of the
intended recipients. This message could not be sent. Try sending message again
later or contact your network administrator. Error is
[0x80004005-000000000-00000000].
Resolution: Advised user to send message using Outlook web
Access. User needs to login to OWA and open the service mailbox. Messages can now be sent without
throttling.
Alternatively, for a user that insist on using Outlook, user
must be given explicit send-as permission to the service mailbox so as to be
able to bypass throttling policy
