Shared booking pages: setup and the mailbox behind them

A shared booking page is a booking calendar for a team: one public page, a staff list of up to 100 people, its own services and its own settings. When you select Create, Microsoft creates a new Exchange mailbox for the page, and that mailbox's email address becomes the page's URL and the sender of every confirmation and reminder. That makes the name and domain the two decisions to get right before anything else. This chapter covers who can create a page, the mailbox behind it, the business information fields and the defaults a new page starts with. For the click-by-click setup, follow the shared booking page setup guide.

Microsoft Learn now calls these "Shared Bookings" and calls the one-person page in Outlook "Personal Bookings", which most people still know as Bookings with me. The differences are in shared Bookings vs Bookings with me.

Who can create a shared booking page#

Five conditions all have to be true. If any one fails, the Create booking page option is missing or returns an error.

Tenant-level changes can take up to four hours to apply. How to restrict creation to named people is in turning Bookings off or limiting who creates pages.

The mailbox Microsoft creates#

Every shared booking page is backed by its own mailbox. Personal Bookings pages don't create one; a 2023 Microsoft Q&A thread confirms the extra mailbox only appears for shared pages, and it's the reason tenants fill up with users called things like "Ben's Booking Page".

Two things here trip admins up.

It isn't a shared mailbox, even though the FAQ says so. The Bookings FAQ states that "Bookings uses shared mailboxes in Exchange" and that shared-mailbox compliance policies also apply to Bookings mailboxes. The FAQ's own PowerShell for finding them filters on SchedulingMailbox, not SharedMailbox, so a script or policy that targets shared mailboxes by type won't find booking pages. Confirm your retention and audit policies cover them by name. What a real shared mailbox can and can't do in Bookings is covered in Bookings and shared mailboxes.

Microsoft documents the default domain two ways. The best-practices article says new pages get an onmicrosoft.com address by default and warns that this "may cause Bookings email notifications to land in recipients' spam/junk folders". The Teams admin article says the organization's default email domain is used. Either way, a Global admin can fix it before pages are created with Set-OwaMailboxPolicy -BookingsMailboxDomain, per policy or for everyone. The custom domain article is explicit that this "will not impact shared booking pages that have already been created". "Custom domain" here means the mailbox domain only; the page still lives on a Microsoft host.

Community reports say booking mailboxes show in the global address list. Microsoft doesn't document hiding them, and the admin side (deleting, auditing, naming) belongs in the admin controls chapter.

The addresses customers see#

The mailbox address turns up in three places, and none of them change when you edit the business name.

Each service also has its own link under Service booking page. In our captures of the public booking page (September 2026), those links take the form …/book/<alias>@<domain>/s/<code>, and the page's own API identifies the business by the same SMTP address. That is why a mailbox rename affects every embed, QR code and campaign link at once.

Business information fields#

Open the page and select Business information in the left pane. Microsoft says this information appears on the booking page "and in messages and reminders sent to them by Bookings".

A page holds one business address, so a business with several sites has to choose between one page per location and one page with a service per location. Setting up Bookings for several locations weighs the two.

Business settings can take up to 10 minutes to show on the public page, according to the services article.

What a new page starts with#

Selecting Create and then Get Started gives you a page with these values. Check each one before you share the link.

If you leave the wizard before Create, Microsoft says nothing is saved.

Organization-wide templates#

There isn't one, as of October 2026. Logo, colours, services, questions and email text are set on each page. The closest options are the clone an existing booking page choice at creation, and the FAQ's suggestion to read one page through Microsoft Graph and create the next from it. The tenant settings under Org settings → Bookings apply to every page but cover access, data collection, indexing, SMS, staff approvals and naming, not appearance. The full comparison is in is there an org-wide template?.

Sharing the page#

On Booking page, Microsoft offers Copy link, social sharing, Email and an embed option that copies the link and an iframe. The tenant settings Block social sharing options and Disable direct search engine indexing change what's available. A service-specific link is in linking to one service, the iframe and its sizing problems are in embedding Bookings, and publishing, branding and access control are in the booking page chapter.

Doing this with BookingsXP#

If the mailbox address in the link is the problem, the BookingsXP hosted page gives you a link at bookingsxp.com/book/<your-name> that shows your Bookings services and times without the address in it, and the embedded widget puts the page on your own site instead. Bookings still holds the appointments and sends the emails from the booking mailbox. You can try it with your page link. BookingsXP is independent and not affiliated with or endorsed by Microsoft.
