Sure. I have a few comments.
Why are you getting the MailMessages twice? Typically, you only get the MailMessages one time (possibly with a filter), then do something with it. However, you are trying to Get MailMessages for each individual mail message, which seems wrong to me. So I am asking if you have a reason for this.
Here are some additional suggestions as far as coding practices:
mail.Subject.Contains("MetroFax") or mail.Subject.Contains("Metrofax") or mail.Subject.Contains("metrofax") or mail.Subject.Contains("METROFAX")
You can change this long condition simply by change the string to upper or lower case.
Also, it is good to use Path.Combine() when joining folders and filenames together. This is helpful, because you don’t need to worry about the ending slash mark. Secondly, use either Now or Today as your current DateTime so simplify things a bit
I also usually suggest putting the year first in the date for folder and filenames, because it sorts better alphabetically.
"yyyy-MM-dd" which will put 2019-07-03 above 2018-12-01, whereas, 07-03-2019 will be below 12-01-2018, even though it is a newer date
The Save Attachments looks good, but if you get an error on it, then you might need to check the attachment count beforehand, like
If mail.Attachments.Count > 0
Other than that, I just don’t know why you have that second Get Mail Message step.
Hope that helps.
