For IT administrators managing Office 365 and Exchange Server, having control over mailbox folder-level permissions is a crucial task. PowerShell, a powerful scripting language developed by Microsoft, offers a convenient and efficient way to control access to specific mailbox folders for users within an organization, including the calendar folder. In this article, I will detail...
The Office 365 Substrate uses Exchange Online mailboxes to store a lot of data that users never see. The data is used by the substrate for different purposes, mostly to make it easier for features to get to relevant information. Microsoft doesn’t document exactly what is stored, where it is stored, and how it is used, so we must poke around in the innards of mailboxes to see what we can discover.
Microsoft has started to flag its intention to deprecate the Search-Mailbox cmdlet. It’s probably the right time to remove this cmdlet from Exchange Online because Office 365 compliance searches can serve the same purpose. At least, compliance searches can do most of what Search-Mailbox does faster. Some functionality gaps need to be filled before we can bid adieu to Search-Mailbox, but its time is coming.
The PST is now a very old file format. Originally introduced to give users the ability to store email moved from their Exchange mailbox, the need for PSTs disappeared years ago because Office 365 users have massive mailboxes. Despite this, some organizations persist in allowing people to use PSTs.
Migration of legacy archives like Enterprise Vault are often left as the last part of the journey from on-premises servers to Office 365. A wide range of third-party migration tools are available, but many complex twists and turns await the unwary as they cope with journal reports, archive mailboxes, splitting and explosions, and the sheer amount of data to be migrated. It’s an interesting problem to solve.
