Hello,
There is an ongoing issue with my Power Automate workflow which apparently can not be solved at all. I have a site on Sharepoint in a list called "Documentation Request". Three times a week, I receive an excel (macro enabled) file from our customer service which contains the new documentation request for each user. I've created a flow which creates the Sharepoint items automatically. Most of the time the flow runs successfully, but there are cases when it stops because it doesn't a specific user (sometimes the error repeats itself 3-4 times in a row). The email addresses are in a table called "NewTasks", in a column called "Owner", and I try to pass the value of each line to Sharepoint to field "Assigned To"
We are talking about only 4 users, the same 4 people must receive their tasks. I've tried using their emails, their name in the database, but the error keeps popping up (The specified user could not be found).

Any idea how to fix it? What did I set up wrong?
Thanks
Attila
