So my boss made a comment that he thought the entire IT department could read his e-mail one day. We recently switched to Office 365 and as many mail administrators know it is possible to grant yourself access to other user’s mailboxes and poke around in most e-mail systems, Exchange included. There are valid reasons for this like when a person has an assistant or multiple people using a shared mailbox.
Regardless the question came up, what if I DO NOT want anyone else to see an event on my personal calendar, especially if I provide access to my mailbox to other users. Luckily in Outlook and Exchange Web App this is fairly easy to do. After all you probably don’t want to let you assistant know you are going for a colonoscopy but you still want other employees to simply know you are out of the office!
When you compose a new message in Outlook simply mark the button that says “Private” on the ribbon. This will hide the details in your Free/Busy information and will by default hide it from anyone who has read permissions to your calendar. Please note however that anyone with at least read permissions could get access to the details if they were technically inclined.
