Hello Forum,
I would really appreciated if you could help me with this problem.
I need to filter outlook emails following 4 criterion:

  1. unread emails
  2. email having a red category
  3. emails having an excel attachements (xls, csv and xlsx)
  4. emails having differents string patterns in its name attachments or the email subject

to comply with it i used a “get outlook mail message” activity. Moreover, in the properties pannel of this activity i selected ( following options)

  • OnlyUnreadMessage to comply with point 1
  • Filter option to comply with point 2: “[Categories] = ‘Red Category’'”
  • for point 3: i used a “for each” activity after the “Get Outlook mail message” and a else if activity inside the “for each” with this condition:

mail.Attachments.Any(function(x) x.Name.ToLower.Contains(“.xlsx” )) or mail.Attachments.Any(function(x) x.Name.ToLower.Contains(“.xls” )) or mail.Attachments.Any(function(x) x.Name.ToLower.Contains(“.csv” ))

Please look at this picture for details
