How to change hanged send/receive group settings

APPLIES TO: Outlook 2016, Outlook 2013

You worked offline for a while, then logged on and pressed F9 to send and receive your messages. A moment later, you realized you’d sent a message from your personal account instead of your work account. You quickly recall the message, and (whew!) the recall succeeds, but you’d rather not do that again.

No problem. You can change your send/receive group settings so you only send messages from specific email accounts.

1. Click Send/Receive > Send/Receive Groups > Define Send/Receive Groups.
2. Click the group you want to change.
3. Change the options. 
   
   
4. For example: If you only want to send and receive mail when you press F9, clear the first Schedule an automatic send/receive every n minutes option.
5. If you frequently work offline, and you check the second Schedule an automatic send/receive every n minutes option, Outlook tries to connect and send and receive your messages at the interval you specify.

If you uncheck the option above that, Outlook won’t send mail from that account when it runs that periodic send/receive operation.
