Two ways to put a shared mailbox in Outlook

Both make the mailbox available. They behave differently once it’s there — and the difference matters more than most people expect.

When automapping is right

  • Mailboxes people check occasionally rather than work in
  • Archives and legacy mailboxes
  • Users with access to many mailboxes


The catch:
no desktop notifications. If a team must respond quickly, automapping alone will frustrate them.

When account mapping is right

  • Mailboxes worked in daily — support, sales, invoicing, dispatch
  • Teams that need immediate notification of new messages
  • Cases where full-mailbox search reliability matters

The trade-off: profile weight. A handful of mapped accounts is fine; twenty is not.

A practical rule: ask whether anyone is waiting for mail in that mailbox. If yes — account mapping. If it’s a reference or archive mailbox — automapping.

You can pick one

SharedConX supports Account Mapping and Auto-Mapping — but only one mode applies per mailbox at any given time. The mode is controlled by the same underlying security group, so you can switch approaches without touching the permission structure itself.
