1. Open Settings > Mail > Sharing and delegation > Mailbox delegation in Zoho Mail.
2. Choose the delegation option and enter the colleague's organisation address.
3. Select Read or Write access. If sending through your identity is required, review the separate Send On Behalf and Send As choices.
4. Send the invitation. The colleague must accept it, then open the delegated mailbox from their account switcher.
5. Run a test message and reply. At an external recipient, inspect the From and Reply-To fields to confirm the chosen sending model.

Decide who handles particular messages, whether the delegate may delete items and how urgent requests are escalated. A delegated inbox can contain unrelated private business information, so choose the scope with the mailbox owner before granting access.

Check where sent messages appear and make sure the delegated identity has the correct signature. The colleague should not need the owner's password or recovery codes.

Return to the delegation list to change permissions or revoke the colleague. Ask them to refresh their session and verify the mailbox is no longer accessible. Review temporary holiday cover after the owner returns.

Sam will cover Ada's customer correspondence during an absence. Confirm the available delegation feature and agree whether Sam needs to read messages, manage them or send through Ada's identity.

1. In Ada's Zoho Mail, open Settings > Mail > Sharing and delegation > Mailbox delegation.
2. Add [email protected] and select the agreed Read or Write access.
3. Review Send On Behalf and Send As separately if replies are required.
4. Send the invitation and have Sam accept it.
5. From Sam's own account, open the delegated mailbox and send a controlled test reply.

Expected result: Sam performs the approved work with the intended sending identity. After the absence, review and revoke temporary access through the delegation controls.

If the mailbox is absent, check invitation acceptance, organisation membership and policy. If it can be read but replies use the colleague's address, inspect the sending permission and selected From field. Do not grant broader rights merely because the first test used the wrong identity.
