What you’re seeing
- Replies sent from the shared mailbox appear in the sender's personal Sent Items folder.
- The shared mailbox's own Sent Items folder is empty or only shows messages from some team members.
- Teammates ask whether a customer has been answered because they can't see the reply.
- Deleted items from the shared mailbox also end up in the person's own Deleted Items.
Common causes
Every environment is different, but these are the causes our engineers find most often:
- By default, Exchange and Microsoft 365 save a copy of sent mail only in the sender's own mailbox.
- The setting that keeps a copy of sent mail in the shared mailbox was never turned on for that mailbox.
- The shared mailbox was added as a secondary mailbox in Outlook rather than as its own account, which affects where sent items are stored.
- A recent migration reset the shared mailbox's sent item settings to their defaults.
Why it matters
A shared mailbox only works for a team if everyone can see the whole conversation. When sent replies are scattered across personal mailboxes, colleagues duplicate responses, contradict each other or assume nobody has replied. When someone leaves the company, their sent replies on behalf of the team can leave with their mailbox, creating gaps in the record you may later need for disputes or audits.

Frequently asked questions
Can we recover past replies into the shared mailbox?
Past messages stay in each sender's personal Sent Items. They can be located there, but fixing the setting only changes where future replies are saved.
Does this affect how customers see our replies?
No. The recipient sees the same message either way; this only affects where your copy is filed internally.
