Download multiple attachments with search condition

Downloads Office 365 email attachments that match search criteria. You can combine conditions (e.g. has attachments only, sent after a date, subject contains text, from a specific sender). Supply SaveFolder and the search parameters in the WITH clause.

Standard SQL query example

This is the base query accepted by the connector. To execute it in SQL Server, you have to pass it to the Data Gateway via a Linked Server. See how to accomplish this using the examples below.

SELECT * FROM download_message_attachments
WITH(
	  SaveFolder='c:\download',	
	  OverwriteFile='True',
 	  MailFolderId='INBOX', --or use mailbox ID
	  UserId='me', --or use "user-id" or use "email"
	  --search mail with attachments, sent after 2023-03-01, subject contains string "invoice" and  from email is microsoft-noreply@microsoft.com
	  SearchCriteria='hasAttachments eq true and sentDateTime gt 2023-03-01 and contains(subject, ''invoice'') and from/emailAddress/address eq ''microsoft-noreply@microsoft.com''  ',
	  EmailBodyFormat='HTML' --or text
)

Using OPENQUERY in SQL Server

SELECT * FROM OPENQUERY([LS_TO_OUTLOOK_MAIL_OFFICE_365_IN_GATEWAY], 'SELECT * FROM download_message_attachments
WITH(
	  SaveFolder=''c:\download'',	
	  OverwriteFile=''True'',
 	  MailFolderId=''INBOX'', --or use mailbox ID
	  UserId=''me'', --or use "user-id" or use "email"
	  --search mail with attachments, sent after 2023-03-01, subject contains string "invoice" and  from email is microsoft-noreply@microsoft.com
	  SearchCriteria=''hasAttachments eq true and sentDateTime gt 2023-03-01 and contains(subject, ''''invoice'''') and from/emailAddress/address eq ''''microsoft-noreply@microsoft.com''''  '',
	  EmailBodyFormat=''HTML'' --or text
)

Using EXEC in SQL Server (handling larger SQL text)

The major drawback of OPENQUERY is its inability to incorporate variables within SQL statements. This often leads to the use of cumbersome dynamic SQL (with numerous ticks and escape characters).

Fortunately, starting with SQL 2005 and onwards, you can utilize the EXEC (your_sql) AT [LS_TO_OUTLOOK_MAIL_OFFICE_365_IN_GATEWAY] syntax.

DECLARE @MyQuery NVARCHAR(MAX) = 'SELECT * FROM download_message_attachments
WITH(
	  SaveFolder=''c:\download'',	
	  OverwriteFile=''True'',
 	  MailFolderId=''INBOX'', --or use mailbox ID
	  UserId=''me'', --or use "user-id" or use "email"
	  --search mail with attachments, sent after 2023-03-01, subject contains string "invoice" and  from email is microsoft-noreply@microsoft.com
	  SearchCriteria=''hasAttachments eq true and sentDateTime gt 2023-03-01 and contains(subject, ''''invoice'''') and from/emailAddress/address eq ''''microsoft-noreply@microsoft.com''''  '',
	  EmailBodyFormat=''HTML'' --or text
)
