Hello all! I’m hoping this will be something fairly easy and obvious that I’m just missing. I’m working on a script that will create a new mailbox in Office 365. This works great, but what I also would it to do is disable Exchange ActiveSync and OWA for Devices for the newly created user. After connecting to Exchange Online through PowerShell I’ve tried the Remove-MobileDevice and Remove-ActiveSync commands, but in those cases it’s looking for a device to remove, where I need it to disable the settings for a specified user. I’ve attached a screen of the exact setting I’m talking about. ---

For the record, I don’t work with exchange and don’t have direct access to exchange modules so I can’t test this, but here’s what I got from google: To disable ActiveSync for a specific user: ``` Set-CASMailbox -Identity -ActiveSyncEnabled $False ``` To disable OWA for a specific user: ``` Set-CASMailbox -Identity -OWAEnabled $false ``` where \ is a GUID, distinguished name (DN), user principal name (UPN), SMTP address, or alias. Apparently, you can also pipe objects into Set-CASMailbox from Get-User or Get-Mailbox but you’ll have to look into that because the online help for the exchange cmdlets looks pretty awful. ---

That worked BEAUTIFULLY thank you. I’ll play around with what I can and can’t pipe in, but at the very least this accomplishes what I needed my script to do. Thank you! ---

No problem! Just try running ``` Get-Help Set-CASMailbox -full ``` and it should tell you what parameters it accepts from the pipeline via property name or value. ---

Yep, and actually I just tested with `Get-Mailbox -Identity j* | Set-CASMailbox -OWAEnabled $False -WhatIf` and it (theoretically) worked perfectly. ---
