Windows 10: Outlook takes 45 seconds to send/receive when connected by ethernet cable, but takes 3...

I use Outlook 365 on a Windows 10 computer. My fast internet is connected by ethernet cable and works great, except when Outlook does a send/receive it takes 45 seconds. If I unplug the ethernet cable, then connect to the same modem by wifi which is slower than the ethernet connection, the Outlook send/receive takes 3 seconds. How can I get Outlook to send/receive quickly when connected by ethernet cable?

Outlook Stuck on Send/Receive

@bartjunited I have one troubleshooting suggestion for you, but it's slightly advanced method to determine a problem, since you so far found no solution it might help you identify a problem. Step 1: Download process monitor: https://learn.microsoft.com/en-us/sy...nloads/procmon Step 2: Download my custom configuration for process monitor, find it in attachment Step 3: Extract archive to your Desktop or some other convenient location Step 4: Run process monitor as Administrator Step 5: Click on File -> Import Configuration menu and import the file from extracted archive called ProcmonConfiguration.pmc Step 6: Click on Filters -> Filter... menu and in a window that appears unckheck "TCP Receive" option and click OK Step 7: Run outlook to be ready to troubleshoot it Step 8: In process monitor click on red "trash bin" icon to clear all contents in process monitor Step 9: In office click on "send\receive" to start mail syncronization Step 10: In process monitor you'll see Cyan colored lines which indicate failed or closed connection or disconnection. In the output you care only about outlook program (ignore the rest), specifically those ports which you configured for your mail in question Make sure that for each such cyan line there is corresponding "TCP Receive" for outlook program If there is no matching "TCP receive" this mean you identified a problem which is that outlook fails to communicate with google for given mail configuration. If that's the case your next step is to reconfigure mail configuration and try again troubleshoot it. You'll know your modification to mail configuration works when you see coresponding TCP receive operation.

 

Ethernet cable not working.

You need to solve your problem one step at a time, e.g. like so:

• Connect your CAT5 cable directly to your router. If it does not work, replace the cable.
• Connect the cable to your TP-Link wall plug. If it does not work, reconfigure or replace the wall plug.

 

Ethernet cable settings

Hi Campbell,

Thank you for writing to Microsoft Community Forums.

Please reply to the follow questions to get a better understanding on the issue:

• What is the model number of your laptop?
  
• Do you have a yellow exclamation on the network icon after connecting the cat 7 cable?
  

However, you can follow the troubleshooting steps from
Fix network connection issues in Windows.

Also, I suggest you to check the laptop manual or laptop manufacturer to know whether the Ethernet port of your laptop supports cat 7 cable.

Hope it helps.
