Send-MailMessage attachments bug by Shay Levi

PS> help Send-MailMessage -Parameter att*

-Attachments <String[]>
    Specifies the path and file names of files to be attached to the e-mail message. You can use this parameter or pipe the paths and file names to Send-MailMessage.

Files piped to Send-MailMessage are bound to the Attachments parameter (which accept ValueFromPipeline and also defines a "PsPath" Alias).
That said, the files we pipe MUST RESIDE in the current working directory, otherwise the files path is not honored. Instead, just the file names are used, concatenated with the working directory path, and the command fails..

PS> pwd

Send-MailMessage : Could not find file 'D:\Document1.txt'.
At line:1 char:30

As a workaround we can first set the current working location to directory where the files are located.

PS>Set-Location D:\SkyDrive\temp
PS> dir *.txt | Send-MailMessage -SmtpServer smtp1 -From me@domain.com -to someone@domain.com -Subject Testing123
