Outlook MFA issues, asks for "need password" and get blank screen
Hello everyone, Premier support is failing to make an progress, I have had a ticket open for a month now with no luck (Getting escalated to Tier 3 this morning). Here is the scenario We have Conditional Access rule that says if someone accesses Office 365 (All Office) from a Non-trusted Location require MFA. For most people it works fine but we have about 10% of the people who run into a really weird problem in outlook only, all other apps (Skype, Word, etc.) work fine. User opens outlook (2016 current monthly) and it shows the "need password" screen at the bottom and no email is sent/received, when we click on it we see a white box comes up and goes away, it does not give them the option. So kind of stuck there! When you go to File->Accounts and do a Sign-out and then try to sign-back in it comes up with the email window but as soon as you submit the email the window goes away and they stay signed out. Here is where it gets interesting, lets say you put someones email in there that works (but is also part of the same MFA rules), it takes that and then brings up the MFA prompt for original user. Once that user then presses approve (MS authentication app, push notifications) then it signs that user in and email starts flowing again. It seems to work for a couple of weeks and then stops again with the same prompt. We put in all the normal reg keys to enforce modern auth (EnableAdal -1, Alwaysusemsoauthforautodiscovery = 1, disableADALaptopWAmOverrride - 1,Disable AADWAM) but I think it may be something on the username side since putting in another username works.
How to Fix PowerShell Script from Basic Auth to Modern Auth
Greetings, I am not a manager of an Exchange Server, I'm just a guy whose PowerShell script used to work until 9/1/2022. Now it doesn't work per the Exchange Basic Auth to Modern Auth update. I have a PowerShell script that, after pinging a server address, uses Basic Auth to send an automated email via Task Scheduler. Microsoft has deprecated Basic Auth in Exchange Online in favor of Modern Auth, but I do not see clear directions for updating a PowerShell script to use Modern Auth. This is an example of the Basic Auth that I need to convert to Modern Auth: $secpasswd = ConvertTo-SecureString “password” -AsPlainText -Force $mycreds = New-Object System.Management.Automation.PSCredential (“alias AT place dot com”, $secpasswd) Send-MailMessage -SmtpServer smtp.office365.com -Port 587 -From alias AT place dot com -To anotheralias AT place dot com -Subject test -Body test -Credential $mycreds -UseSsl" I cannot find ANY information on how to update this script to use the Modern Auth method. Can someone please point me to an example of a PS script with email Modern Auth being used in a similar script or share the specific code for what I need to do to update and run the above script?
