Organizations, and teams within organizations, often have several different email threads going in all directions at one time. It’s easy for lines to cross, information to get lost or overlooked, and for communication to break down. Site mailboxes enable you to store team or project-related email in one place, so that everyone on the team can see all communication.
On the Quick Launch, click Mailbox.
The site mailbox opens as a second, separate inbox and folder structure, next to your personal email account. Mail sent to and from the site mailbox account will be shared between all those who have Contributor permissions on the SharePoint site.
Tip: Did you know you can also use a site mailbox to collaborate on documents?
Add a site mailbox as a mail recipient
By including the site mailbox on an important email thread, you ensure that a copy of the information in that thread is stored in a location that can be accessed by anyone on the team.
Simply add the site mailbox in the To, CC, or BCC line of an email message.
You could even consider adding the site mailbox email address to any team contact groups or distribution lists. That way, relevant email automatically gets stored in the team’s site mailbox.
Send email from the site mailbox
When you write and send email from the site mailbox, it will look as though it came from you.
Because everyone with Contributor permissions on a site can access the site mailbox, several people can work together to draft an email message.
To compose a message, simply click New Mail.
This will open a new message in your site mailbox.
