Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
After some testing, One Drive and the Autosave feature only worked intermittently. I read a post about changing the mtu setting for the network adapter. The article is: http://www.techkhoji.com/some-websites-not-loading-in-vpn-problem-fix/amp/
Following the article's instructions I lowered the mtu to 1472, which worked for me. After the adjustment One Drive and autosave worked properly, and websites that wouldn't open did.
I'll keep testing, but for now the mtu size change appears promising.
The article also mentions changing DNS settings if mtu change does not work. Instructions are given for that, too.
Amazing StephenRappaport thank you!
I can't begin to say how long I have sought a resolution to the Microsoft account sync issue whilst using NordVPN.
Having followed the suggested fix from **http://www.techkhoji.com/some-websites-not-loading-in-vpn-problem-fix/amp/** and lowering my MTU from 1500 to 1472 on my Ethernet & WIFI adaptor (not the the NordVPN adaptor), I can report that my Microsoft office sync issue has been resolved.
I have also ensured that all my TCP/IPv4 connections are pointing to Google's DNS 8.8.8.8 & 8.8.4.4
I hope this feedback helps others in a similar situation.
