Hello,
I was trying to use de Send Outlook Mail Message but my attachments are bigger than 4MB, so I found the new Office365 package that has a bigger limitation.
But when trying to send to multiple e-mails I encounter the error below.
βToβ property of SendMail in Office365 activities package is String array. So you need to set String[] type variable (like arrStr = {"a@exmplae.com","b@example.com"} ) or use Split method like SendMail.Split(";"c)
