Question on Issues with Exchange Online
I mean it's a stretch, but did you guys setup MFA at all on your accounts? MFA will cause Outlook desktop to stop working if you don't enable Modern Authentication.
It's possible the multi region stuff doesn't like having modern auth off as well. Check your tenant and make sure you guys use Modern Auth?
Get-OrganizationConfig | Format-Table -Auto Name,OAuth*
Other things I believe changed recently are some old TLS no longer being supported recently could have hit and causing issue? I dunno just tossing a few idea's out.
Hi Chris,
I have MFA enabled on my account, but not the rest as of yet. The output of the command you suggested is OAuthClientProfileEnabled is False.
Thanks for the suggestion. We are a small org, so only a few hundred users... not sure what the whole multiregion thing is as we are 100% stateside... unless its referring to different regions within the US...?
Thanks!
- Oh you said different regions I was thinking the whole different data centers etc. I really think you should try enabling modern auth to support the newer auth methods it should be true. I can find how to enable but quick google search will show you how. And do it for Skype for B at same time. There really isn’t any side effects other than a possible password prompt. Worth a shot and you need it for future state anyway and is recommended to use.
Unless you have old versions of office etc. you’ll need to research that part. - Also. MFA requires modern auth to be on so that would explain if yours is not working.
