Using Adsiedit to Add or Remove E-mail Aliases on On-Premises Active Directory – Office 365

If you are synchronising your Office 365 account with your on-premises exchange/Active Directory, you will know that you cannot edit exchange user properties using the Office 365 administrator portal.
If you try, you will come across this error or a similar one:

The operation on mailbox “X” failed because it’s out of the current user’s write scope. The action ‘Set-Mailbox’, ‘EmailAddresses’, can’t be performed on the object ‘X’ because the object is being synchronized from your on-premises organization. This action should be performed on the object in your on-premises organization.

The reason for this is due to the fact that the AD and O365 are synchronised. Office 365 knows this and does not allow you to make any changes on O365 if there is a corresponding attribute that links up with your Active Directory.

Set a Room Mailbox to Show Details of a Meeting in its Calendar – Office 365

You may notice that meetings with a ‘Room’ mailbox will by default only show a “Busy” status.
Many, including the organisation I work for, wish to have (at the very minimum) the following displayed in the Room’s calendar:

  • Organiser of the meeting, and
  • The subject of the meeting

Below I will demonstrate how to set the permissions so that all meetings (except those explicitly marked as ‘Private’) publicise the above details to all who view its calendar.
