Hi @Neeraj Kumar
If you make use of the POP3/SMTP VBO, and Exchange is your target mail server, I would start to look at alternatives. I hope to have a new version of a POP3/SMTP VBO available in the November timeframe, but it will be based on MimeKit
instead of the regular SmtpClient
object within the .NET Framework.
Microsoft Graph is certainly an option, but introduces its own set of issues you'll need to consider. One of the biggest has to do with the size of attachments. There are two different ways to add attachments to a mail in Graph: Direct
and Upload Sessions
. Direct attachments can be no bigger than 3MB. Attachments via Upload Sessions max out at 150MB. We still need to investigate this a bit further, but my understanding is that if you have something larger than 150MB you would likely need to upload that file to OneDrive and then include a link to it in your email.
As we gather more information we'll post it on the Community.
