Bookings with me through M365 is not syncing with my custom working hours

I am experiencing an issue with Bookings with Me in Microsoft 365 where my custom working hours are not displaying correctly in my shared booking link.

Setup:

  • Org-managed M365 tenant based in the UK
  • I am based in Germany (timezone set to Europe/Berlin in Outlook)
  • Outlook language set to English (UK)

What I have configured:

  • Monday–Thursday: 10am–4pm
  • Friday: 10am–2:30pm

What the shared booking link shows:

  • Monday–Thursday: 8am–5pm
  • Friday was previously not showing at all

What I have already tried:

  • Set working hours in both Bookings with Me and Outlook Calendar work hours settings
  • Verified timezone is set correctly to Europe/Berlin
  • Tested in an incognito browser window (no caching issue)
  • Deleted and re-entered custom hours, saving each day individually
  • After re-entering hours, the settings screen shows the correct times, but the shared booking link still displays incorrect hours

The discrepancy between what is saved in settings and what appears in the shared link suggests this is a sync issue rather than a user input error. Has anyone encountered this and found a resolution? Could this be related to the timezone difference between the UK tenant and my Germany-based account?

    Hi @Lily Bergmann, 

    Thank you for describing your setup and the steps you’ve already taken so clearly.  

    From your description, this does indeed sound more like a sync or service-side issue rather than something misconfigured locally. You’ve already covered the key checks around timezone, cache, and reapplying the settings, so there’s not much more to troubleshoot from the user side. The difference you’re seeing, especially the two-hour shift, could be related to how the service is interpreting timezone or tenant-level settings, but normally it should handle that automatically. 

    Please kindly understand that this is a user‑to‑user community forum. I don’t have access to internal diagnostic tools or backend systems, nor do I have permissions to directly investigate or fix the issue. I can only share suggestions based on research and experience from similar cases in the community, and I truly appreciate your understanding. 

    At this stage, I would strongly recommend that you submit a support ticket with Microsoft. This allows the backend engineering team to review your Bookings with Me configuration, check for any synchronization delays or inconsistencies, and confirm whether this is a known issue affecting your tenant. 

    If you’re not an admin, it would be best to reach out to your Microsoft 365 administrator and gently ask them to raise the ticket on your behalf.

    Tips: You can switch off the Support Assistant as shown in the screenshot, then type a few short characters into the search box and select Get Help. After that, wait for the Contact Support button to appear and click it. At the final step, be sure to clearly describe your request in the description fields so the support engineers can quickly understand your issue and assist you more effectively.   

    Once the ticket opens, a technical support technician can conduct a remote session to investigate the situation, review the backend configurations, and run the necessary synchronization tools to resolve the issue. If further intervention is required, they can refer the matter to a specialized team for in-depth analysis. In this situation it’s very likely the fastest and most reliable way to get a clear answer and proper resolution. 

    Hope this helps point you in the right direction, and I really appreciate the effort you’ve already put into narrowing this down.

    Thank you again for your understanding.

    This behavior is consistent with known limitations and quirks in the “Bookings with me” and Bookings time/availability model rather than a simple user input error.

    From the available information, the following points are relevant:

    1. Bookings and Bookings with me rely on Outlook on the web’s language/time‑zone settings for the booking calendar. If Outlook on the web is already set to Europe/Berlin and English (UK), then the booking calendar itself should be using that time zone correctly.
    2. The self‑service booking page (what is seen via the shared link) has its own regional settings (language and time zone) that are separate from the booking calendar. If those regional settings are not aligned with Outlook’s time zone, the public page can show different hours than what is configured.
    3. Bookings with me also interprets availability based on calendar status (Free/Busy). For example, all‑day events default to “Free” and therefore do not block Bookings with me, even though they visually occupy the day in the calendar. This is a known cause of discrepancies between what users expect and what the booking page shows.

    Given the context, the most concrete, supported steps are:

    1. In Outlook on the web, confirm language/time zone (already done in this case) – this controls the booking calendar itself.
    2. Open the Bookings/Bookings with me page and check the regional settings for the self‑service booking page, ensuring the time zone there matches Europe/Berlin. Misalignment here is the most likely cause of the 8:00–17:00 display instead of 10:00–16:00.
    3. Review the personal calendar for all‑day or spanning events that are set to “Free.” Change such events to “Busy” if they should block Bookings with me availability. This ensures the booking page correctly hides those times.

    If Outlook’s time zone and the booking page’s regional settings are aligned, and there are no “Free” all‑day events affecting the view, but the shared link still shows 8:00–17:00 instead of the configured custom hours, this falls into the category of a synchronization or product issue rather than a configuration problem. In that case, the next step is to open a support ticket with Microsoft 365 support so the tenant and mailbox can be checked for known Bookings/Bookings with me sync issues.

    There is no indication in the provided material that a UK‑based tenant with a Germany‑based user should, by itself, cause the specific 8:00–17:00 vs. 10:00–16:00 discrepancy, as long as both Outlook and the booking page regional settings are set consistently.
