Quite simply - for 2003 - 2010, the administrative templates have made these very easy.  

On 2013 - after getting the new ADMX/ADML sorted, I did easily find and disable the email signatures piece (ours is managed elsewhere).  

However - Whether it was provided by Microsoft, or created by the previous admin, we had a convenient ADM template for turning off the ability to modify default stationary, Modify Default Theme and New Mail Using -> More Stationery

This covered all the bases so emails don't go around with pink backgrounds etc. 

Am I restricted to creating a new custom admx template to sort this for 2013?  I suppose I could review the older ones and try to mimic with 2013 in registry and then create the new template but that seems like quite a lot.  If that's the only way though - I'm happy to do it.  Just figured I'd check here first! 

Thanks! 

Hi,

Do you want to disable the button showing in the image below?

If so, please follow the following steps:

1. Open the Group Policy Editor.

2. Locate Administrative Templates > Microsoft Outlook 2013 > Disable Items in User Interface > Custom

3. Double click to open Disable command bar buttons and menu items

4. Select Enabled. Click Show button after Enter a command bar ID to disable.

5. Type 5611 in the Value column.

6. Click OK. Click Apply and Click OK.

7. Restart Outlook. Now, the button will be grayed out.

More information about using Group Policy to disable commands, please refer:

Hope this helps.

Thanks.

Hi Steve,

Outlook 2013!?

You answer only disables the stationary when using 5611 Command Bar ID via GPO ADMX template for the Outlook 2013 so the File - New Items - E Mail Message Using - More Stationary option will be disabled.

But, even with that option being disabled users still can go to File - Options - Mail - Stationary and Fonts and change their Themes in Outlook!

Is there any way to disable the Stationary and Fonts button in Outlook 2013 or the Theme button so users can't change their default email fonts?

Your answer would be greatly appreciated.

Nick, I ran into this same issue with the "File-Options-Mail-Stationary" in our 2013 deployment and solved it by creating a registry preference in a User GPO.

By setting the preference under the "Policies" reg key, a user can choose a different theme, but as soon as they click OK, the setting flips back.

Set these REG_SZ values in GPO (User Configuration\Preferences\Windows Settings\Registry) 

[HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\15.0\common\mailsettings]
"NewStationery"=""
"NewTheme"=""

Nsojka, 

I tried your solution (see image below) but it still won't work for Outlook 2013 users. Any idea why? It work's perfectly for Outlook 2010.

Thanks Nate and sorry about a very late reply. I'll have to test it on our system to see if it works. I should be able to insert the the registry key by settings the values in REGEDIT directly to first see if it works. If it does then I'll proceed to the network deployment via GPO ADDS.
