End-to-end configuration of collaborative email infrastructure, SharePoint team sites with permission tiers, and room resource mailboxes — simulating a real-world IT department environment on a live M365 tenant.
Microsoft 365 Admin Center → Teams & Groups → Shared mailboxes
Created and configured a shared mailbox at support@anish.website to simulate a real IT support team inbox. Added David Wilson and Sarah Smith as members, then validated end-to-end functionality — sending emails from the shared address and confirming receipt in a user inbox — all without requiring a dedicated licence for the mailbox itself.
support@anish.website provisioned in Microsoft 365 Admin Center under Shared mailboxes.
David Wilson and Sarah Smith granted Send As and full access permissions to the mailbox.
Test email sent from support@anish.website via Sarah Smith's account; received in David Wilson's inbox.
Opened shared mailbox inside Outlook alongside personal account — demonstrated parallel mailbox management.
Confirmed sent email appears in Support HelpDesk Sent Items folder, not the sender's personal account.
Shared mailbox operates without an assigned licence — cost-efficient for team email scenarios.

Exchange Admin Center → Recipients → Resources
Created a Room resource mailbox (Board Room) via the Exchange Admin Center to enable calendar-based meeting room bookings. Configured auto-accept booking options, then tested the full workflow — booking the room from David Wilson's Outlook calendar and verifying the room's acceptance confirmation reply.
Board Room mailbox (boardroom@anish.website) provisioned in Exchange Admin Center with booking options configured.
Created a "Team Meeting" event from David Wilson's Outlook calendar, inviting the Board Room as a resource.

Exchange Admin Center confirms "Resource mailbox creation successful!" after completing all four setup steps: Resource Setup, General Information, Booking options, and Review
New event created with Board Room (boardroom@anish.website) added as a resource — availability shows as "Available" for the 7:00–7:30 PM slot
David Wilson's inbox shows "Board Room accepted" — the Team Meeting is confirmed on both the user's calendar and the room's calendar for Wed 27 May, 7:00–7:30 PM
SharePoint Admin Center → Active sites → IT Internal Department
Provisioned a private SharePoint team site ("IT Internal Department") for the IT team's internal file storage. Configured a three-tier permission model (Members, Owners, Visitors), created a confidential document library folder with unique restricted permissions, uploaded an IT policy document, and tested external document sharing — all through SharePoint's modern permission management interface.
IT Internal Department SharePoint site created as a private group from SharePoint Admin Center.
Three-tier model: Members (Edit), Owners (Full Control), Visitors (Read) applied at the site level.
"Confidential – HR only" folder created with unique permissions breaking inheritance from the site.
IT policy.docx uploaded to the Documents library and made available to site members.
IT policy.docx shared with an external Gmail account — sharing invitation confirmed.
Users assigned to SharePoint groups (Sarah Smith as Member, David Wilson as Visitor) via the Permissions panel.
