OWA

Question

Can we disable the 'Bcc' option in OWA through office 365 admin center..?

Answer 1

Hi Jishnu,

No, there isn’t any policy or rule to disable the ‘Bcc’ option in Outlook Web App. One related option is “Always show Bcc” button if you select “Another user” option in Exchange Admin center. Once this button is disabled, the Bcc column will show as minimized button when users create an email.  

Here are the steps:

1. Sign in Exchange Admin Center with an Office 365 admin account.
2. Select “Another user…” option on the Upper right corner.
3. Select an user account and choose OK.
4. Navigate to settings > mail and disable the “Always show Bcc” feature.

If the above steps don’t archive your goal, we suggest you submit your feedback to our related team via this link: https://outlook.uservoice.com/forums/313228--outlook-on-the-web-office-365. Many products' features/services have been designed based on customers' constructive ideas.

Thanks for your understanding.

Thanks Barry & Solar-Eclipse..

Can we disable the same in OWA for mobile device..?

Answer 3

*Set-MailboxMessageConfiguration *****@domain.com -AlwaysShowBcc $true

Note, that just determines the default behavior, whether BCC is shown or not shown when a new message is created. A user can still manually add BCC recipients even if set to $false.

So the answer to JISHNU MOHANDAS's original question, is No you can't turn off BCC for your users.

Answer 4

Hi Jishnu,

There is a PowerShell command to disable BCC feature for one single user. To apply the PowerShell command to multiple users, we recommend that you seek help from our TechNet support engineers. They are more familiar with the PowerShell commands. Here is the link: https://social.technet.microsoft.com/Forums/office/en-US/home?forum=outlook

Also, the PowerShell command I found is:

*Set-MailboxMessageConfiguration *****@domain.com -AlwaysShowBcc $true

Note: You need to connect to Exchange Online PowerShell before performing the above command.
