We are preparing for our migration to Office 365 (from BPOS). Many of our accounts will be OWA-only users. Managers at these locations wish to block IM functionality.
Is it possible to disable IM functionality from OWA in Office 365?
I understand that you would like to disable the IM functionality from Outlook Web App. To achieve this goal, we need to create a new mailbox policy. I have provided the detailed steps as below:
1. Connect Windows PowerShell to Exchange Online: http://help.outlook.com/en-us/beta/cc952755.aspx?sl=1.
2. Run Windows PowerShell to create a new mailbox policy. For example, to create a new mailbox policy which is named Policy1, run the following command:
New-OwaMailboxPolicy -Name Policy1
Set-OwaMailboxPolicy -Identity Policy1 -InstantMessagingEnabled $false
3. Apply this policy to a user such as firstname.lastname@example.org, run the following command:
Set-CASMailbox -Identity email@example.com -OwaMailboxPolicy Policy1
Thank you for your answer. I really appreciate it.
However, it seems the need to block IM availability in OWA is now in question. If I do happen to proceed with your suggested steps, I will let you know of my progress.
