"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

HI Jeff,

What email server do you have?

If you connect in Outlook Web App with the same mailbox, do you receive emails?

Hemil AquinoNetwork EngineerCommented:
Sounds like a vague question. You haven't specified any detail related why you cant send and received. It could be many issues such as:

1- No internet in your computer.
2- Your mail server is not connecting to your email hosting.
3- Your Outlook profile may be corrupted, the list continue.

It might happen due to :
Large or over-sized PST file
The wrong configuration of Outlook
Corrupt Outlook data files
Outdated anti-virus programs
Intentional/unintentional user profile deletion
Malware attack
The sudden termination of Outlook
Abrupt shutdown of the system
Poor Internet connectivity

1. Make sure that you are connected to the Internet
2. Make sure that your Outlook email account settings are correct.
3. Delete suspicious email messages from your mailbox.
4. Check your antivirus manufacturer's website for additional suggestions.
5. Configure your firewall software to enable Outlook to access the Internet.
6. Repair your MS Outlook.


To fix it, you can run ScanPST.exe utility provided by Microsoft. Refer below link to locate ScanPST.exe utility in Outlook 2016.

Hope it helps..!!

Since you haven’t described anything detailed in the query, there are two chances for Auto Send/Receive option in Outlook stops working and they are:

1. Send/Receive is Deactivated

- In Send/receive Tab >> Send/Receive Groups >>  Disable Scheduled Send/Receive (if it is enabled.)

2. Corrupt Send Receive Group


1. Go to File >> Options >> Advanced
2. Go to Send Receive section >> click on Send/Receive >> New >> name for New Group >> Ok
3. At Send/Receive Settings, check "Include the selected account in this group"  >> OK
4. Now disable the ‘All Accounts’ group to avoid corruption by unchecking every box
5. Restart Outlook.

If these solution cannot resolve your issue, then it can because of some other issues as explained by other experts. You can use ScanPST.exe tool to fix minor corruptions and can go for reliable commercial utility to repair corrupted Outlook PST file in safe and secure way.

Feel free to ask if you have any further query.

Thanks & Regards

I am agree with Karl's suggestion. Its just a settings issue. It should work, still if same issue persist then try again by disabling add-inns you are using in Outlook 2016.

Try checking whether you are able to receive and send mails from OWA, if yes then the problem is only with your outlook.
Try disabling the cached mode by following the below steps.
File->Account settings->Select your email account-> Double Click on it->under offline settings un check the box Use Cached Exchange Mode ->Next->Ok.
