o365 Outlook in Citrix opening up but with a white box

[Stuart Jewell]

Any assistance would be greatly appreciated, only recently when opening microsoft outlook in citrix, the authentication box is blank so the user cannot enter their password. symptoms for this happening is that the user changes their password and then they get the blank authentication box when opening outlook. I would assume that the old AD credentials get cached in the user app data folder in the UPM folder causing this to happen.

 

It has only started happning for the last couple of weeks and any user changing their password becomes affected by this.

 

does anyone have a workaround or a permanent solution to this issue?

Hi Stuart,

I assume this is happening on Windows Server 2019? If so, it's a known issue with the AAD Broker Plugin, which MS has not yet fixed.

The only workaround that I know if is this Powershell script, which fixes/resets  the AAD Broker Plugin during login:
 

if (-not (Get-AppxPackage Microsoft.AAD.BrokerPlugin))

{ Add-AppxPackage -Register "$env:windir\SystemApps\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy\Appxmanifest.xml" -DisableDevelopmentMode -ForceApplicationShutdown }

Get-AppxPackage Microsoft.AAD.BrokerPlugin

You should configure it as a login script or an external task in WEM.

You don't mention what OS you are working on here, but the most common solution seen is to add this to a PowerShell login script:

if (-not (Get-AppxPackage Microsoft.AAD.BrokerPlugin)) { Add-AppxPackage -Register "$env:windir\SystemApps\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy\Appxmanifest.xml" -DisableDevelopmentMode -ForceApplicationShutdown } Get-AppxPackage Microsoft.AAD.BrokerPlugin

thank you all for the quick responses its on Windows server 2012 & 2016 images

Hmmm....I can't remember ever seeing this in 2012 R2 and 2016. Is anything getting logged in the event viewer, when the user launches Outlook?

[Dennis Parker]

Haven't seen the issue on 2012 personally, but on 2016 clearing credentials from credential manager would usually clear it up. Upgrading Office to newer releases stopped it from happening as well, when they stopped using credential manager to store Outlook credentials.

thank you all for the quick responses does anyone know or point me in the right direction of how to get the AAD.brokerplugin on the 2012 r2 image, seems like microsoft didnt have that installed on it ?
