This looks like the booking is being created successfully on the backend, but the user-facing confirmation step is failing afterward.

If the meeting appears in the calendar despite the error, I’d check the browser/network response at the final submission step and whether the issue reproduces across multiple users and browsers.

Since others are seeing the same behavior and basic cache/browser tests haven’t helped, this may be a Microsoft Bookings service-side issue rather than a local configuration problem. It would be worth checking Microsoft 365 service health and opening a support case with the affected booking page URL and timestamp.

Hi Helen,

Since the appointment is being created successfully and the meeting invitation is received, the booking transaction itself appears to be completing correctly. The error message may be occurring during the final confirmation step in the Microsoft Bookings web interface rather than during the actual booking process.

As an end user, please try the following:

Test the booking page in an InPrivate/Incognito browser window.
Test with a different browser or device.
Clear browser cache and cookies.
Verify whether the issue affects all users or only specific users.

If the behavior persists across multiple browsers and users while appointments continue to be created successfully, you should reach out to your IT admin and ask them to run the following command in PowerShell.

# Connect-ExchangeOnline
# Check current status 
Get-OrganizationConfig | Select-Object BookingsEnabled, BookingsPaymentsEnabled, BookingsSocialSharingRestricted
 
# Enable Bookings if it is off 
Set-OrganizationConfig -BookingsEnabled $true

If the issue persist, the most effective next step is ask your IT admin to use their admin credentials to submit a support request through the Microsoft 365 Admin Center on your behalf and providing the screenshots of the error.

This route ensures that a Microsoft support engineer can initiate a remote session to investigate backend configurations, run advanced diagnostic tools, and, if necessary, they can request to escalate the case to specialized teams with access to internal systems and logs. These backend resources are essential for resolving issues that go beyond what’s visible in the user interface.

I hope this helps you resolve the issue quickly. If you have any questions or need further assistance, please feel free to share them in the comments on this post.

We are having the same issue. Have tried all recommended solutions with no impact. THis feels like a systemic issue as there are others I have spoken too that just recently stated experiencing the same issue.

thanks for any incite you can provide.

Hi Jim,

I think it would be best to ask your IT administrator to open a support request with the Microsoft Support team through the Microsoft 365 Admin Center. Since this issue appears to be affecting multiple users, it may be related to a service-side problem that requires further investigation by Microsoft.

hello @Ivory

Opened a support ticket when I was sure it was not just us. Issue is not currently showing in the active issues being worked on. Appreciate the suggestion.

Hi Jim,

I appreciate all the effort you've put into troubleshooting this. At this stage, it would be beneficial for Microsoft to investigate the issue. Additional reports from affected users can help increase visibility, so I would suggest that Calot report it as well.
