Alert Emails are not being received to Shared Mailbox - They are received without issue to a named persons mailbox

jasonf1971, are you referring to when a shared mailbox is a recipient it doesn't receive it or if the shared mailbox is the account you have defined as the SMTP account for auth to send from?

Yes what i am reffering to is the shared mailbox / email address is the recipient for the email alerts..... for as i am aware the smtp account is the noreply solawinds account 

jasonf1971, when you simulate it does it show as sending successfully and then you never receive it? to be honest as far as SolarWinds goes it doesn't make any distinction between the two. It is completely transparent to SolarWinds if one is a shared mailbox, a distro list, or a user mailbox. As long as its a valid email it should send. I would also talk to whoever is in charge of your mail to see if they can run a message trace or look at the shared mailbox settings. It is entirely possible that they limited who that mailbox could receive mail from. 

yes simulates without issue shows as sending successfully 

jasonf1971, yup at this point id reach out to whoever is in charge of mail to run a message trace and look at the mailbox settings. 

ok thank you

For anyone coming across this, check to make sure the shared mailbox is configured to "allow messages from outside the organization" (Office 365) or from unauthenticated users (on-premises).
