Use the Corporate Mailbox feature to send OnceHub notifications from your company's corporate Office 365 account instead of the default mailer@oncehub.com. This brands your email communications, providing a more professional experience for your guests and users. 

Note: Depending on your plan type, you may need to purchase the Security and Compliance Add-On to make use of this feature.

Impact of Enabling the Corporate Mailbox Feature for Your Account

Once connected, all scheduling notifications sent to Guests and Hosts will originate from the designated corporate email account.

Only an Administrator or the Account Owner is authorized to configure this feature. Once configured, it will apply to all Users within the account.

Note: Microsoft is discontinuing the basic authentication protocol necessary for Corporate Email functionality with Office 365. Should connection via SMTP prove unsuccessful, it is recommended that each user utilize the alternative option detailed at the conclusion of this article.
