Email on Lumia 950 error 0x86000c0a

[Windows Central Question]

In past few days this error message comes when trying to sync email. Says "problem syncing eas.outlook.com at the moment. Wait a little while then try again.
Error code 0x86000c0a

Phone is up to date with latest software. Mail eventually comes through after a few trys but then next time same recurs.

Any suggestions how to fix
