Hi Sri,
The e-mail send to outlook integration is a manually executed task from within SAP Business One.
Unfortunately in the current release, there is no automation built in.
Please refer to The SP_TransactionNotification Stored Procedure
There is an option for post (after the transaction os added in SBO) transaction notification that can be used, that you can query information and despatch via an email.
Note that you need to configure the SQL mailer as well for this to work effectively.
Regards,
Kiran
