The Microsoft Teams reminder app works by using a structured system integrated with SharePoint Online. Administrators manage and store all event data in SharePoint lists. Every day, a scheduled Power Automate Flow checks these lists to find upcoming events based on specific date rules. Once identified, the flow sends out notifications to selected recipients through Microsoft Graph or adaptive cards in Teams. For birthdays, the bot sends reminders both one day before and on the birthday itself, while ensuring the person celebrating is excluded from the recipient list using conditional logic. Administrators can easily configure event types, messages, timing, and target audiences—all without needing to change the flow itself. Any updates made to the SharePoint lists are instantly reflected in the reminders, ensuring everything stays fully automated without requiring manual synchronization.

Birthdays and Holidays Reminder Bot for Teams
Description
Introducing Birthdays and Holidays Reminder Bot for Teams, the ultimate solution for seamless team communication!
Birthdays and Holidays Reminder Bot for Microsoft Teams is the easiest way to stay updated on important team events. The bot automatically sends reminders about birthdays, vacations, and other key dates directly. Managed through SharePoint lists, it runs fully automated – no manual reminders needed.
Features
- Birthday reminders. The bot sends two birthday notifications: one the day before and one on the actual date. It excludes the birthday person from the recipient list. This eliminates the need for manual coordination and ensures consistent recognition.
- Upcoming Leaves Notifications. The bot checks leave records in SharePoint and notifies the team in advance. This improves visibility into team availability and supports better workload planning.
- Invoice Reminders to Contractors. The system retrieves invoice deadlines from SharePoint and sends scheduled reminders to external contractors or internal stakeholders. This reduces the risk of missed payments and supports financial discipline.
- Notifications. The bot sends all alerts directly to Microsoft Teams using adaptive cards or plain messages. This ensures high visibility, reduces email clutter, and keeps all updates in the team’s main workspace.
- Data Managed Through SharePoint. Administrators configure and maintain all records in standard SharePoint Online lists. This centralizes control, simplifies permissions, and allows for quick changes without editing the automation.
System Requirements
- Available for Microsoft Teams (Desktop or Web): The bot sends notifications directly to users or channels within Microsoft Teams. The organization must have been enabled under Microsoft 365.
- Packaged as Power Automate (with Environment Access): The solution runs as a cloud flow built in Power Automate. The user deploying the bot must have access to create and manage flows in a Power Platform environment.
- SharePoint Online All data (birthdays, leaves, invoices) is stored in SharePoint Online lists. The solution requires a Microsoft 365 license that includes SharePoint and allows list creation and item-level access.
- Teams Bot (registered in Azure AD) The bot runs as a Microsoft Teams bot, which must be registered in Azure Active Directory. Admins must configure permissions, Teams app policies, and potentially side-load the bot if it’s not published in the App Store.
- Microsoft 365 Licensing equires Microsoft 365 licensing that includes Teams, Power Automate (Standard or Premium, depending on connectors used), and SharePoint Online.
