Hi Lawrence,
Thank you for contacting us. Based on your description, you're using remote desktop protocol (RDP) to access your office computer. And in your office computer, you have set up an SAS program to generate and send emails via Outlook automatically. But recently
these emails stuck in Outbox folder until you log in the office computer.
Does your office computer never sleep or hibernate? To my knowledge, if the computer is in sleep or hibernate mode, the network will disconnect by default. That could be a possible cause. In this scenario, you can try to disallow the computer to go into
asleep mode or open Group Policy to allow network connection in sleep mode to check if it helps.
1.
2. Press Win + R and type "gpedit.msc", then navigate to Computer Configuration > Administrative Templates > System > Power Management > Sleep Settings.
Besides, for the further analysis, I'd like to collect the following information.
1. What's your Outlook desktop client version? Please capture a screenshot via File > Office Account > About Outlook.
2. Does this account an Office 365 account?
Regards,
Marvin
