Microsoft Copilot
Take control of Exchange mailboxes
Rencore inventories Exchange user and shared mailboxes with their storage, quota and last activity, relates each one to its Entra ID user, and lists the redirect rules set on them. A policy flags the mailboxes that redirect mail to external domains, so you find them by rule instead of by ticket.
Exchange mailboxes pile up with no owner and no lifecycle
The questions are the ones you already ask of a Team or a SharePoint site: who owns it, who has access, is it still used, and what happens when it fills up.
Who owns it
Shared mailboxes and the mailboxes of people who left collect over the years. Nobody can say who answers for them.
Where its mail goes
A redirect rule can send a mailbox's mail on to an external domain. Nobody notices until the mail has already left the tenant.
Whether it is still used
A mailbox with no recent send or read activity still holds a licence and still holds data.
What Rencore sees and does in Exchange
Every mailbox in one inventory, related to its user
Rencore scans Exchange mailboxes and relates each one to its Entra ID user, or to the deleted user when the account is gone. The mailbox sits in the same inventory as the Teams, sites and OneDrives of the same people.
- User mailboxes and shared mailboxes as separate segments
- Storage used, quota values with the percentage reached, last activity date, archive flag and send, receive and read counts
- Redirect rules for each mailbox, with their forward and redirect addresses and whether they send mail to an external domain
- Scanned continuously. Findings are as fresh as the last scan
- In a test tenant on 13 October 2026, the mailbox inventory matched the Exchange admin center
A policy for mail redirected to external domains
The finding is a policy with a severity, a category and a trend, so you see which mailboxes send mail out of the tenant and show an auditor that the control is running.
- Mailboxes with external redirect rules: every mailbox with at least one redirect rule that sends mail to an external domain, rated High under Security
- Shared mailboxes and user mailboxes as segments, so you can narrow the inventory to either one
Where Exchange coverage stops
What Rencore does with mailboxes today, and what stays in Exchange.
No convert to shared
Rencore cannot convert a mailbox to a shared mailbox. You find the mailbox in Rencore and make the change in Exchange.
No actions on mailboxes
Rencore has no automation action for mailboxes. It finds and reports them, and the change stays in Exchange.
No quota or redirect rule changes
Quota values and redirect rules are read and reported. Rencore does not change them.
Scan-based, not real time
Rencore detects and reports from scans, and does not block mail flow or sit in the path of a message.

What does Rencore inventory in Exchange?
User and shared mailboxes with their storage, quota values, last activity date, archive flag and mail counts, each related to its Entra ID user, plus the redirect rules set on each mailbox, including whether a rule sends mail to an external domain.
Does Rencore read the mail in our mailboxes?
No field of the Rencore mailbox object holds message content. The object holds sizes, item counts, quota values, dates, the archive flag and send, receive and read counts, plus the relation to the user.
Can Rencore convert a mailbox to shared or change its rules?
No. Converting a mailbox to a shared mailbox, changing quotas and editing redirect or inbox rules are not part of Rencore today. Rencore finds the mailbox and reports it, and the change itself stays in Exchange. There are no automation actions for mailboxes.
Does the Exchange admin center already cover this?
It covers mailboxes, and in a test tenant on 13 October 2026 the Rencore mailbox inventory matched it. It is where you change a mailbox, and Rencore does not replace it. What Rencore adds is a policy for mail redirected to external domains, with a severity and a trend, and a relation of every mailbox to its Entra ID user, all next to Teams, SharePoint and OneDrive in one control plane.
How is Exchange coverage licensed?
Exchange is part of the Digital Workplace module, together with Teams, SharePoint, OneDrive, Viva Engage, Planner and Entra ID. The pricing page has the full plan comparison.
