Powerapps mail attachment from SQL/Blob Storage

Posted on by Kollenel26

Hi guys, I've been having some trouble with the following scenario, I recently moved my pdfs from a SharePoint list to a SQL database and have been storing pdfs in a varchar(max) column, this works fine for viewing and saving. However, I now need to send those documents as an email attachment. Using the Outlook365 attachment gives me an error that it is not in blob format. I then created an Azure blob storage container and save the pdfs there, but I do not know how to get the documents from the blob storage into a mail attachment in powerapps, any help would be greatly appreciated

Hi @Kollenel26 ,

Could you please share a bit more about the PDF file data stored in your SQL Table? Is it stored as Blob data?

Do you want to retrieve all blobs (PDF files) from a specific folder in your Azure Blob Storage, and then attach them as attachments of the email?

Based on the needs that you mentioned, I have made a test on my side, please consider take a try with the following workaround:

Set the OnSelect property of the "Send Email" button to following:

Office365Outlook.SendEmailV2( "User1@email.com", "Subject Text Here", "Email Body Message Here", { Attachments: ForAll( AzureBlobStorage.ListFolderV2("Type your Specific Folder Id here").value, { Name: DisplayName, ContentBytes: AzureBlobStorage.GetFileContent(Id), '@odata.type': "" } ) } );

Note: You need to add Office 365 Outlook connection and AzureBlobStorage connection within your app firstly.

More details about sending an email with attachments in canvas app, please check the following article:

Thanks a million, that works, apologies, I am quite new to all this, so I followed one tutorial where I used the add picture control to upload a pdf and then create a file in my azure blob storage, your method works to send the mail but ideally I would like to select one or more out of a folder. for one component of the app.

For the next component: I am creating certificates per candidate using a flow, this updates a varchar(max) column in a SQL database with the Muhimbi converted pdf per learner, now I could create a blob for each of them simultaneously and retrieve them using your code, I would just need to figure out how to filter my blob container. Or if I could somehow upload the SQL column data to the blob storage that would be ideal seeing as I could then create and delete once the mail is sent and keep my blob container empty for neatness sake, I am just not so clued up with the data types, the converted pdf is in the form of "JVBERI0XlJ..." which is a massive text file, I am not sure how to upload that as a blob and then get selected ones back again?

P.S I am using varchar(max) in the SQL table because that is the only way I could get pdfs to display in the pdfviewer in the app, the image type gave all sorts of errors
