macOS 10.15.4 Internet Accounts Intune device not recognized
ollie_bk Still no fix. Microsoft and Apple would need to acknowledge the issue before a fix will be worked on. If someone from Microsoft is working on this then please acknowledge here so that we can know this is being worked on.
If this is happening only for some people and not for others then I'd imagine that it has to do with a conditional access requirement that affect some people and not others.
Microsoft pushed Company Portal 2.3.200301 as part of the Slow Ring sometime on 6 April; once the update is installed, it looks like for us, authenticating first while on the corporate VPN (so Conditional Access doesn't apply) allows to get a more durable OAuth token even once disconnected from the corporate network (tested by a few of my colleagues over the past few hours, now testing on my machines).
Update: it looks like the issue persists after all, I had to re-authenticate after about an hour. Sorry about the false hope.
Update 2: the workaround seems to work for users that have a single macOS machine (with or without iCloud Keychain enabled) but fails for users with multiple macOS devices + iCloud Keychain sync, presumably because the Keychain sync attempts to copy the original OAuth token to other Macs, triggering the re-auth. Nope.
