Block Senders and Mark Messages as Junk in Outlook
The quickest method to handle individual spam emails forwarded from your Bookings account directly within your inbox.
By manually blocking the senders or marking the emails as junk, Outlook's filtering system learns to prevent similar external messages from cluttering your primary inbox.
Open your Outlook desktop or web application and find the unwanted email that was forwarded from your Bookings calendar.
Right-click the spam message in your inbox list to open the context menu.
Hover over 'Junk' in the menu, then select 'Block Sender'. The email address will be added to your blocked senders list, and future messages from them will be automatically moved to the Junk Email folder.

Frequently Asked Questions
Why does my Bookings calendar automatically forward emails to me?
Microsoft Bookings automatically provisions a background user account for each new calendar you create. By default, it forwards any incoming emails directed to this calendar address to the owner's personal inbox to ensure no client communications are missed.
Can I completely disable email forwarding from a Bookings account?
Yes, but this typically requires a Microsoft 365 administrator. An admin can use Exchange Online PowerShell to access the specific Bookings mailbox and disable the automatic forwarding rules, though this means you will have to check the mailbox manually for client replies.
Do I need a paid license for the Bookings account to change its spam settings?
Generally, Bookings accounts function as unlicensed mailboxes. However, if an administrator needs to log in directly to adjust specific mailbox-level rules, delegate access, or apply advanced Exchange configurations, a temporary license may need to be applied.
