Two people look identical in Outlook
Recipient Guard steps in when Outlook AutoComplete makes the wrong mailbox look deceptively familiar, for example when display names are the same for different people.
Product
Recipient protection built around real Outlook mistakes
Recipient Guard is designed from the moment Outlook AutoComplete feels helpful right up to the second it helps you select the wrong person's mailbox. The product is focused on protecting your workflow whilst helping it stay efficient and effective.
What makes it useful
- Intervenes before send, not after the mistake
- Shows likely alternative mailboxes with context
- Adds friction only when the recipient choice is genuinely ambiguous
Recipient Guard catches the moment Outlook AutoComplete selects a familiar-looking personal mailbox instead of the intended work or client address.
Where Recipient Guard helps most
The strongest value comes from the patterns Outlook often makes feel safe when they are not.
The prefix matches, but the domain does not
It spots addresses like name@oldcompany.com versus name@currentcompany.com, where one small difference can send the message to the wrong place.
A personal mailbox is selected instead of a work one
That overlap is common in real inboxes, so Recipient Guard treats it as a meaningful ambiguity rather than trusting Outlook to guess correctly.
What the user experiences
- A review dialog when the recipient choice looks risky
- The selected mailbox and why it triggered attention
- Known alternative mailboxes that also appear plausible
- A calmer email experience
Why this matters
Most Outlook mistakes are not dramatic moves but can be dramatic moments. They are ordinary Outlook moments: the wrong John Smith, the wrong domain, your client's personal address, or an external recipient selected too quickly. Recipient Guard is built specifically for those moments.
