Before ForEach loop, use Message Box and print below value and check it whether its printing any value or not.

                                mails.Count

I think mails is Null. Please run in debug mode and see what is the value for mails.

From the debug mode I see “messages” (the next variable after mails ) holding the list of mail messages.

In your ForEach please use that variable instead of mails.

If mails is what you intend to use: mails should be of type List (System.Net.Mail.MailMessages). The output from the activity above it (the get mail mesage activity) should be assigned to mails.

May I know in what type of variable did you saved output of Get Outlook Mail Message activity ?

Is it System.Collections.Generic.List<System.Net.Mail.MailMessage> or not ?

System.Collections.Generic.List<System.Net.Mail.MailMessage>

Yes,Iam using this variable only.

Then mails.count should work if mails is of type List. Could you please show me screenshot of mails variable type ?

I think you should be using for each item in messages. Please give that a try. mails is of type Ienumerable in your case.

You need to store Get Outlook Mail Messages activity output in messages variable but not mails.

Do one thing. Delete all variables and go to output section under properties of Get Outlook Mail Message and press Ctrl+k and enter name like mailMessages and then check it.
