Then I took the first mail from inbox and putting that in fokus by moving to another folder called (mail in progress).
Then I’m again using Get Outlook Mail Messages activity to read that mail from (mail in progress) and finding the subject.

When Í got the subject… I need to seach again if I have more e-mails with same subject in the (Inbox) and If I have any, Then I need to give categorie as Double and put all those mails one ny one to an other folder called (Duplicate)

Create a new list and use it in Assign activity

ex: New_List = List_Email.Distinct().ToList()

I need to match the mail subject of(Mail in progress) to the mails located in (inbox) and get a list of those to assign a tag and then move to another folder.
