Calender remainder on Shared Group

Hi @Nishith Konchady 

Based on my research and testing, I would like to share the insights I have gathered so far, in addition to what Q&A Assist has already confirmed regarding Microsoft 365 group calendars not sending Teams meeting notifications: 

1/ In the context of Teams meetings, attendees are required. If no attendees are added, the entry is treated as an appointment rather than a meeting. For meeting events, adding attendees allows the reminder to appear as expected. 

2/ For receiving reminder notifications, Microsoft provides an official workaround for shared mailboxes by adding them as a separate account in Outlook. This approach allows reminders to be surfaced correctly. 

 You can find the detailed steps here: Add a shared mailbox as an additional account in Outlook Desktop | Microsoft Learn 

There is also a possible workaround within the Microsoft 365 group context. You can send an email related to the meeting. By applying the Follow in Inbox option that best fits your needs, you will receive email notifications in your personal mailbox. This can help ensure you are reminded of the upcoming meeting through email notifications. 

I understand that these workarounds may not fully align with every scenario. With that in mind, I strongly recommend sharing your feedback through Ideas · Community.

This is the official channel for submitting suggestions and ensures your feedback is reviewed by Microsoft’s product teams, where it can help influence future improvements. 

I hope this provides some additional insight. Please feel free to share any updates after reviewing the information. 

Note: Please follow the steps in our documentation to enable e-mail notifications if you want to receive the related email notification for this thread.

Reminder pop‑up alerts are controlled by each user’s own Outlook client and mailbox, not by the Microsoft 365 Group calendar itself.

For Microsoft 365 Group calendars:

• Events placed only on the group calendar will not generate reminder pop‑ups for members unless those members are explicitly added as attendees or add the event to their own calendars.
• There is no tenant‑ or group‑level setting to force reminders for all group members without listing them as attendees or having them add the event to their personal calendars.

To have reminder alerts, each user must either:

1. Be added as an attendee to the meeting, or
2. Add the group event to their personal calendar (for example, from the group calendar view in Outlook), where their personal reminder settings will then apply.

The behavior described in the question (reminders without adding users as attendees or to their own calendars) is not supported.
