Hello Vatsal, I'd be happy to help you.
Personally, since I manage a variety of folders for Outlook, what helped me in order to get notified for emails in non-inbox folders in Outlook is to set up a rule that forwards emails that arrive in a specific folder to your inbox. This way, you will receive a notification for the email in your inbox, and you can still keep the email organized in the other folder.
To set up a forwarding rule in Outlook, follow these steps:
Open Outlook and click on the "Home" tab.
In the "Move" group, click on "Rules" and then select "Manage Rules & Alerts".
In the "Rules and Alerts" dialog box, click on "New Rule".
In the "New Rule" dialog box, select "Apply rule on messages I receive" and then click on "Next".
In the next step, select the conditions that you want the rule to apply to, such as the sender, subject, or keywords in the email. Then, click on "Next".
In the next step, select "forward it to people or public group" and then specify your inbox as the forwarding address.
In the next step, you can choose to apply any exceptions or additional conditions, if needed. Then, click on "Next".
In the final step, give the rule a name and click on "Finish".
Once you have created the rule, it will automatically apply to any new emails that meet the specified conditions and forward them to your inbox. You can also set up a separate rule that triggers a specific notification sound or alert for emails that are forwarded to your inbox. This way, you can easily distinguish between regular emails and those that have been forwarded from other folders.
