preventing duplicate emails in office 365

If you're using Microsoft 365 email groups to scan a subset of mailboxes in a domain, we can't prevent two scans on each message. If a message is scanned twice, you see duplicate entries in Message History and other reports. In that case you see a log event and rejection in your Sophos Gateway logs, and no event in your Sophos Mailflow logs. In some cases, for example with a real-time block list (RBL) in place, Sophos Gateway blocks inbound emails before we can detect whether a Sophos Mailflow connection exists for that domain. If we detect both connections on a domain, Sophos Gateway forwards incoming messages to Sophos Mailflow for scanning and processing. If you don't disconnect from Sophos Gateway, you're still protected and we prevent dual scanning if possible. What happens if I have both connections active? You must undo any changes you made in your Microsoft 365 domain settings when you originally connected the domain to Sophos Gateway. In Domain details, click Delete domain.

Click Email Security > Settings > Domain Settings / Status.

To delete your Sophos Gateway connection, do as follows. You might want to run Sophos Mailflow alongside Sophos Gateway for a short time to make sure everything is working, but we strongly recommend that you delete the Sophos Gateway connection as soon as possible. If you don't delete the Sophos Gateway connection, your messages could be scanned twice. If you set up a Sophos Mailflow connection to a Microsoft 365 domain that is already connected to Sophos Gateway, you should delete the Sophos Gateway connection to prevent duplicate scans. Update description column to get the value of Description. You can send the email to the people in the Assigned to column or to the people in the Created By column. Set the value as current item: description. Add a condition ‘If current item field equals value ’. Add a workflow on the list to start when an item is changed. Choose list setting and enable ‘ Send e-mail when ownership is assigned’. When create a task item ,add the description column to get the same value of the Description. Add a column named description on the Task list.

If you want to send alert based on the Description column change. If you choose cancel when nothing changes ,it will not send an alert. Do you mean that you created an alert on the Task list to send alert when anything changes ?If so ,when you open the Edit Item page and choose save to close the form
