Hi,
What's your detailed Outlook version and Windows version? And the Exchange version? Did the issue occur randomly or continuously? Please make sure you have installed latest updates for Windows and Office applications.
If you are using Outlook 2016 within Office 365 ProPlus, please click File > Office Account > Update Options > Update Now to keep Outlook 2016 the latest version. You can also click About Outlook to collect the Outlook version.
Additionally, please check the following settings in Outlook 2016:
Click File > Account Settings > Account Settings, on the Email tab, double click your Exchange account, confirm if you are using Cached Exchange Mode. Click More Settings, go to Security tab, make sure the option "Encrypt data between Microsoft Outlook and Microsoft Exchange" is checked. Click OK to save the settings.
If the issue persists with the correct Outlook settings, please go to Control Panel > Mail > Show Profiles to create new profile and reconfigure your Exchange account to have a try.
Regards,
Winnie Liang

I'm afraid I have the same issue. Using Windows 10 64 bit, CONSTANTLY, i. e. automatically updated, using Outlook 2016 (Office 365 subscription) with your own service's Exchange server - so no idewa whiah version this is. I have uninstalled Outlook, reinstalled, with no change whatsoever.
This is extremely aggravating as Outlook is my main (surprise) mail client and I find myself unable to work with it for more than a few hours at a time.
Apart from telling me to reinstall Windows and waste 2 years of my life, does anyone have a solution to this inane situation? I'm seeing a lot of users with the exact same issue, so clearly not a client install problem.
Would be nice to see serious tech support on this one.

If you are running Windows 10, you can perform a "Network Reset" through Settings/Network & Internet. I have this very same problem frequently and have tried the Online Repair and Uninstall/Reinstall, but had no luck with this approach. Resetting the NIC seems to do the trick for me every time. Good Luck!

Are you going through a phone switch (VOIP) to your computer for the physical connection? If so, try using a dedicated switch, or bypass the phone with another drop. Also, be sure that your switchport is set to auto negotiate. If you still have issues, try hard setting an IP address (rather than using DHCP) on your NIC.

Yes! After two months problems with Outlook 2016 exchange server cache connection finnaly the last two posts help me.
1. I have Voip phone connected with my Win 10 PC network.
Go to network option , seek and find reset NIC network.
Then set static ip,gateway,dns in your netwotwork interface.
Restart your PC
2. Now you need to check network interface - LAN connection.
Seek and find Flow control option and set it to disabled.
3. seek and find IPv4 checksum offload and set it to disabled.
4. Hyper V or VMWare
Do you have HyperV or VMWare? If you have need to check out and deselct this service from your network interface.
5. Remove rx & tx check sum from
- flow control
- Ipv4 Checksum
- Tcp checksum
- Udp checksum
- Buffer set it to 128
5. Restart PC and evrething will run as you expected.

How can you propose your answer as the correct when the OP upvoted both BoTech4965 and MightySW as the correct answers that helped him, and stated that in his reply.
