I'm trying to setup the following.
This person has already an existing mail adress from company 1 (tenant), we are trying to create a shared mailbox from company 2 (tenant)
He wants to use his existing mailbox from company 1, to receive all mails as a copy from company 2 (Shared mailbox).
I've tried to forward all mails in the shared mailbox to an external mailbox.
I've put myself as full control of the shared mailbox - opened the outlook in owa enviroment -settings - mail - account - forwarding.
After setting this up, sending a test mail to see if everything worked, all admins in the tenant received a low severity alert message:
Details: MailRedirect. This alert is triggered whenever someone gets access to read your user's email.
Description: This alert is triggered when someone in your organization creates an email forwarding or redirect inbox rules using Outlook web app or Powershell -V126.96.36.199
I couln't find any alert policies that i can adjust to stop this alert message from sending to our admins.
Is this a single alert message? to warn admins, or wil this alert acquire everytime a mail gets forwarded?
I've also tried a different method through the admin exchange panel directly in the shared mailbox but the mail adress cant be found, this mailbox is already added as guest in the contacts as you can see.
