Outlook is always starting in Admin-Mode

Question

Outlook is always starting in Admin-Mode

Carsten Hartmann 1

Hello Community,

I am encountering some problems with Outlook 2016 since I have upgraded our clients from Win7 to Win 10.

The problem is that outlook is always running in admin-mode. I cannot remove the "Run as Administrator" ("Als Administrator ausführen" in the Screenshot) since it is not checked on any files/shortcuts. Also I am missing the Compatibility-Tab on outlook.exe. Fully reinstalling Office is also not an option since we are using like 30+ language packs on all clients which would take forever for to un-/reinstall.

I checked online for solutions but none of them seem to work, most of them using the Comp.-Tab which I don't have.

Looking forward for your ideas :-)

Best regards,

Carsten

Hi @Carsten Hartmann ,
In order to verify your issue, please provide some information:
How do you make sure that Outlook is running as an administrator?
Does the problem occurs to single client or all clients?

When I start Outlook, UAC pops up and asks for higher permissions. Due to this, users can not Drag&Drop attachments into Mails from the Desktop or Network-Shares for example. This problem occurs on all clients that have been upgraded from Win7 to Win10 via MS Upgrade (around 25). Win10 Clients that I've installed manually do not have this problem. Upgraded and manually installed machines do use the same Software, Settings, Plugins, etc, so the only difference is the OS installation method.

Best regards,
Carsten

Hi @ CarstenHartmann-7058 ,
According to my search, I found that this is a know issue occurs when installing Windows updates.
Are these computers logged in with administrator accounts?

If not, create a new administrator account or change the account type and set it as an administrator account .
Here is an article about create an administrator account for your reference
Switch to Administrator account to see if the issue persists.

The User-Accounts are Members of the Administrators-Group. I've just tested removing and adding them back to the group, unfortunately error persists.

Hi @Carsten Hartmann ，
Thanks for yous reply and sharing your test.
So given this case, you may try modifying registry to disable UAC .

Open registry and locate to HKEY_LOCAL_MACHINE \SOFTWARE \Microsoft \Windows \CurrentVersion \Policies \System
Find the entries and set value to 0
ConsentPromptBehaviorAdmin = 0
EnableLUA = 0
PromptOnSecureDesktop = 0

(Important: Follow the steps in this section carefully. Serious problems might occur if you modify the registry incorrectly. Before you modify it, back up the registry for restoration in case problems occur.)

Disabling UAC works. I am not sure if this is a satisfying solution though, disabling UAC feels like a security issue to me.

Well, like I said, disabling UAC is no solution more like a hot fix, this lowers the security of the clients by a lot and we get a lot of files from our customers and subcontractors from all around the world.

On the clients that have been installed with win10 manually the UAC is turned on and the error does not occur, so the issue must be somewhere else.

Hi @Carsten Hartmann ,
If you don't want to disable UAC, you may try to change the UAC settings:
Open the Control Panel, go to User Accounts and then click Change User Account Control settings.
In the User Account Control Settings window, you'll see a slider with four options, choose the setting you want and press OK.
