Hi,

i have Flow when new Mail arrives it should get the attachments and send them with send an email action.

I have multiple attachments, so i use Array Variable to store them.

I read a lot about the "" around ContentBytes in Array Variable are problematic, but i don't have those.

I tried these scenarios:

{
"Name": "@{outputs('Get_Attachment_(V2)')?['body/name']}",
"ContentBytes": @{outputs('Get_Attachment_(V2)')?['body/contentBytes']}
}

-> can't open file

{
"Name": "@{outputs('Get_Attachment_(V2)')?['body/name']}",
"ContentBytes": "@{outputs('Get_Attachment_(V2)')?['body/contentBytes']}"
}

-> can open file, but it is blank

{
"Name": @{outputs('Get_Attachment_(V2)')?['body/name']},
"ContentBytes": @{outputs('Get_Attachment_(V2)')?['body/contentBytes']}
}

-> can't open file

I add the attachment in the send email action like this:

What am i missing?

Thanks for your help

@LuITS Hi,

You have to use base64ToBinary() function, otherwise outlook can not open the attachment files.

below is for your reference.

code view part:

"value": { "name": "@items('Apply_to_each')?['name']", "ContentBytes": "@base64ToBinary(outputs('Get_Attachment_(V2)')?['body/contentBytes'])" }

screen shot.

The attachments are coming out of the Get Attachments V2 action as base64, you'll need to convert them to Binary to make it work. In your array, use this for the ContentBytes section:

base64ToBinary(outputs('Get_Attachment_(V2)')?['body/contentBytes'])

The reason this is different than the tutorials is because those are using the original Get Attachments action, which encoded the files as binary from the beginning. This was changed in the V2 action.

If this comment resolved your issue, please mark it as the answer to help future users searching for this problem.

EDIT: Ah, stampcoin beat me to it.
