Restrict/disable outgoing emails from Acumatica to not land in the “Sent Items” of Outlook

Hi ​@Avishka ,

Based on how Acumatica integrates with Microsoft Exchange, there isn't a direct setting within Acumatica to prevent outgoing emails from being saved to the Sent Items folder.

When Acumatica sends emails through an Exchange or Office 365 account, it typically uses the Exchange Web Services (EWS) SendAndSaveCopy method. This method is designed by Microsoft to ensure a record of the communication exists within the mailbox, so a copy is automatically placed in Sent Items.

Recommended Workaround

Since this behavior is hardcoded into the interaction with Exchange, the most effective and common workaround is to manage this on the Exchange/Outlook side:

Create an Exchange Mailbox Rule: You can set up a server-side rule in Outlook or Exchange Admin Center for that specific email account. Configure the rule to automatically move or delete items from the "Sent Items" folder if they originate from Acumatica (for example, by filtering based on a specific subject keyword, the sending application, or by applying it to all emails if the mailbox is used exclusively by Acumatica).

Hope above helps!!
