Bookings page not reflecting time off blocks

Question

Bookings page not reflecting time off blocks

Kelli Wallace 0

my bookings page calendar is not reflecting any time off blocks that have been added for my staff.

It reads only their available hours that reside within their staff profile.

Any thoughts?

Hi @Kelli Wallace,

Thank you for the detailed description regarding the synchronization issues you are experiencing with Microsoft Bookings.

It appears the system is currently reflecting only the working hours defined in the staff profiles while failing to account for time off blocks. Furthermore, the inability to select the option for Office calendar events to affect availability points to a few specific configuration triggers.

I have outlined some steps to help locate the potential causes and suggestions to resolve this:

1/ Confirm how the staff member was added (internal vs guest/external).

The primary reason the option for calendar events to affect availability becomes unavailable is the account type of the staff member.

Internal users: These accounts reside within your Microsoft 365 tenant and allow Bookings to read free or busy data.
Guest or external users: If staff are added via external email addresses, Bookings frequently lacks the permission to access their Exchange calendars.

If your staff are currently added as guests, their Outlook blocks will not automatically flow into the Bookings schedule.

2/ Try to add time off directly in Bookings.

If you need to block availability immediately and cannot utilize Outlook synchronization, you can manage this directly within the Bookings application:

Navigate to the Bookings calendar.
Select the option to add time off.
Choose the specific staff member and define the required date and time range.

This method effectively overrides other settings and ensures the staff member is not bookable during those periods.

3/ Regarding enabling full Outlook synchronization

To allow Outlook events to dictate availability automatically, the staff members should be set up as internal tenant users. By readding them using their internal Microsoft 365 accounts, you will be able to select the setting for Office calendar events to affect availability within their staff profiles.

It is also helpful to ensure that the various layers of scheduling settings are aligned:

Organization business hours.
Individual staff working hours.
Availability settings within the specific service being offered.

Please be aware that calendar updates may experience a brief delay before they are reflected in Bookings. Additionally, factors such as time zone discrepancies or the configuration of multi day services can sometimes impact how personal calendar availability is accounted for.

I hope this helps address your concerns. If you have any additional questions, please don’t hesitate to reach out.

Thank you. The 'Add Time off" is not working as it should. staff are still showing available regardless. They are showing available to services they are not assigned to as well.

Hi @Kelli Wallace,

Thank you for the update. If the Add time off feature is not successfully blocking availability and staff members are appearing as bookable for services to which they should not be assigned, this typically indicates an issue within the configuration or assignment layers of Microsoft Bookings rather than the time off entry itself.

To begin the troubleshoot process, please verify the bookings calendar and staff selection. Please confirm that you are editing the correct Bookings calendar that supports your public booking page. Within the Add time off entry, double check that the affected staff members are explicitly selected for that specific time range.

Building upon the calendar verification, it is important to validate the service to staff assignments for each offering. If a service is assigned to multiple individuals, the system may still show availability if any one person in that assigned group remains free.

After that, you can review booking logic and auto assignment settings. Misconfigurations in service assignment logic can cause unexpected behavior. Please reconfirm that each service has staff assigned explicitly and that the assignment method is set appropriately, such as using Assign automatically only where applicable.

Furthermore, please recheck staff working hours to ensure that availability is not being inadvertently reopened. Verify whether staff availability is driven by general business hours or custom hours. It is important to ensure that availability is not being reopened by overlapping schedule layers or a lack of defined hours for a specific day.

Finally, please allow a short period for these updates to propagate through the system. Availability changes can occasionally take several minutes to reflect accurately within the Bookings interface.

If you are still able to reproduce these availability issues after confirming the service assignments and time off entries on the correct calendar, I recommend opening a support ticket (if you are not admin, please contact your IT admin to request a support ticket on your behalf). This will allow for a formal server side investigation of your Bookings mailbox configuration.

Thank you for your patience and understanding.

Thank you for your help.

I did notice that the system takes several minutes to reflect changes.

I have the availability across the board set as bookable when staff are free.

If I add one day of availability and then the time off blocks, it will read correctly.

Any more than that and it starts reading available for those time periods regardless of if assigned to the service or if a time off block is present.

I will have my admin put in a help ticket for someone to assist.

Hi @Kelli Wallace,

Thank you for that specific observation. The fact that the system honors time-off blocks for a single day but fails over a longer range suggests a logic conflict in the Availability Hierarchy, where service-level settings may be overriding individual staff calendars.

I recommend providing these final details to your admin to include in the support ticket:

1/ Verify service availability overrides

Check if the service has "Custom availability" rules active. If a service includes a date range override, the system might prioritize those broader settings over individual staff "Time off" blocks when multiple days are selected.

2/ Unassigned staff visibility

Staff appearing for services they aren't assigned to typically points to a synchronization lag or a phantom assignment in the back end.

3/ Provide technical details

To expedite the investigation, include the following in the ticket:

The specific Service and Staff names affected.

The distinction between the "one-day" success and the multi-day failure.

This will help the support team determine if this is a localized sync issue or a broader tenant-level issue.

I appreciate your patience and understanding.
