how can we enable the notifications for a shared mailbox, please support.)

To enable notifications for a shared mailbox, you may need to check the settings in your Microsoft 365 admin center. Here are some steps you can follow:

1. Access the Microsoft 365 Admin Center: Sign in to the Microsoft 365 admin center.
2. Navigate to Groups: Select Groups > Active groups.
3. Select the Shared Mailbox: Find and select the shared mailbox you want to configure.
4. Check Group Settings: Ensure that the settings allow notifications to be sent to members of the shared mailbox. You may need to adjust settings related to email notifications and permissions.
5. Member Subscriptions: If members of the shared mailbox want to receive notifications, they should subscribe to receive copies of all the email messages that are received by the group. This can be done in their individual mailbox settings.

If notifications are still not coming through, ensure that the shared mailbox is properly set up and that there are no restrictions in place that might block notifications.

Whether notifications for shared mailbox are available in Classic Outlook depends on how the shared mailbox is being accessed. If you have been granted Full access permissions on the mailbox, it's best to configure it as additional account instead of having it automapped or added as additional mailbox. You can do this via File > Add account > enter the shared mailbox address > enter your credentials when prompted to authenticate. This in turn will enable Outlook to treat the shared mailbox as any other "regular" account and enable notifications and all other features you might be accustomed to. Let me know if you need more detailed instructions.

Alternatively, you can add the shared mailbox's Inbox to favorites, configure rules for notifications and some other workarounds, depending on your configuration. Check out this article for more details: https://robert365.com/article/new-mail-alert-for-delegate-or-shared-mailboxes
