Most “missing” emails have been filed somewhere else.
- Check your Junk Email folder.
- In Outlook, check the Other tab next to Focused at the top of your inbox.
- Search your whole mailbox for the sender’s name or email address.
- If you have rules set up, check one hasn’t moved it: in Outlook, File → Manage Rules & Alerts.
- Ask the sender to check the address they used, and whether they got a bounce-back message.
Still not there?
Raise a request with the sender’s email address and roughly when they sent it. We can check whether it reached us, or was held by the email security filter.
