For organisations of 50+ people on Microsoft Exchange

Exchange won't automap through security groups. We fixed that.

Grant Full Access to a security group and the permission works — but the shared mailbox never shows up in Outlook. It’s been that way for over a decade, and Microsoft hasn’t changed it. 

SharedConX is the only software that makes automapping work with  security groups.

Every Exchange admin ends up choosing one of these

Direct permissions per user

Automapping works. The cost:

  • ×Every hire, transfer, and departure is a manual change
  • ×Permission structure degrades a little more each month
  • ×Within a few years, nobody can explain half the entries

Security groups, no automapping

The structure stays clean. The cost:

  • ×Users add every shared mailbox to Outlook themselves
  • ×Your service desk explains it — again, and again
  • ×No desktop notifications until it’s set up

Neither is good. Most organisations pick one, regret it, and switch to the other a few years later. Here’s the technical reason Exchange behaves this way →

Keep your groups. Get your automapping.

You keep managing permissions through security groups. SharedConX makes the mailbox appear in Outlook for every group member — and disappear the moment someone leaves the group.

  1. A user is added to the security group — by you, by your IAM system, by your onboarding process.
  2. SharedConX detects the change — the Manager monitors group membership continuously.
  3. The mailbox permission is applied — set automatically, logged completely.
  4. The mailbox appears in the user’s Outlook — no ticket, no script, no user instructions.
  5. Leaving the group reverses everything — permission revoked, mailbox unmounted, automatically.

What you get

Environment analysis

SharedConX reads every existing permission, flags orphaned and duplicate entries, and cleans them up with your approval.

Group-based automapping

Permissions follow group membership. Team changes propagate automatically.

Seamless integration

Works directly with your existing Exchange and Outlook environment.

Complete audit trail

Every permission change is logged continuously — who, when, triggered by what.

Scales with you

Stable from 50-person organisations to environments with over 10,000 mailboxes.

Least privilege

No Domain Admin rights required — limited, purpose-specific permissions.

Automapping or account mapping — choose per mailbox

Automapping

The mailbox appears as an additional folder tree. Fast and unobtrusive — ideal for archives and occasional access.

Account mapping

The mailbox is added as a separate account: desktop notifications, complete search.

Built in a 1,500-mailbox environment

SharedConX exists because we ran into this problem ourselves, managing 1,500 shared mailboxes across roughly 6,000 users. After deployment, administrative effort dropped by up to 70%.

SharedConX automates mounting and unmounting shared mailboxes completely transparently for end users. This takes massive load off the service desk. Thanks to complete logging, time savings and ROI can be demonstrated precisely.Johannes F. — verified review on G2

Not sure it's for you?

If you already have a PowerShell script that handles this and your environment is small, you might not need us. SharedConX vs. custom scripts →
