This started recently... All settings seemed good - nothing I know of had changed, I've tried removing and re-adding the Gmail account. I had two Gmail accounts working fine in Outlook 365 until they weren't.

The Gmail accounts seem to add ok - they show "successful completion". And tell me I need to restart Outlook. I close & restart... then I get "The name cannot be matched to the name in the address list" error.

And no new Gmail account listed ...

I have tried removing the OST files - just in case they'd been corrupted...

I looked for updates - none found.

Turned off VPN...

What else can I try? Using a browser to access Gmail works fine. Outlook on my iPhone accesses Gmail just fine...
