Hello Led Gardner1
Good day! Thank you for your contribution to the Microsoft community. We will be happy to help you.
I've read your thread and got some background information about your script. Based on your description, you want to removing duplicate emails automatically.
We also did other tests and consultations on my side and I'm afraid I haven't found a way to do it. It seems that this is currently not feasible. When dealing with duplicate emails in Modern Microsoft, it's important to note that there isn't an automatic feature to remove them. This means that you will need to manually identify and delete the duplicate emails.
We understand your concern about this feature, that it helps you improve your efficiency in such a busy daily work schedule, but since it is related to the design of products, it is highly recommended that you submit your valuable feedback directly to the Microsoft product development team by accessing the help of your dedicated app > submit feedback or by publishing on Idées · Community (microsoft.com) for feature requests.
If there is anything we can do or if you have any other concerns, please do not hesitate to contact us. Your satisfaction is our top priority, and we're here to support you in any way we can.
We apologize for any inconvenience this may have caused and appreciate your understanding and patience.
Your kind understanding is greatly appreciated.
Sincerely
Shajia Afrin | Community Moderator
