Hello everyone,
I was trying to create a flow to automate creation of Sharepoint list items from flagging emails in outlook.
It worked well with me through the below steps:

However, I noticed some duplication of records, therefore, I tried to manage this issue by fetching the email conversation ID in each share point item in order to use this field as a validation through standard condition as per below flow:

Unfortunately, this did solve my issue but make situation worst 😅 as I ended up with more duplications.

Could anyone tell me what's did i do in this automation? and what is the best way to prevent such duplications?
Best regards,
