Now that you're receiving the emails, you'll want to set up filters to help you declutter your Outlook Inbox. While Outlook will automatically apply the "Sent" label to emails you send from Accelo (since the sender address is, well, you), the byproduct of the BCC notifications is a lot of unwelcome noise in your inbox. To cut this out, you can set up rules in Outlook so that emails you send skip the inbox get marked as read and optionally have them assigned to a separate folder.
To configure a rule to declutter your Outlook inbox:
Click the Settings gear at the top-right corner of your Outlook screen.
First, give your rule a name.
On the Add an action dropdown, first select the Mark as Read option. Next, click the Add another action option.
