How do you give secure cover access to a colleague's mailbox?

How do you give secure cover access to a colleague’s mailbox?

You give secure cover access to a colleague’s mailbox with proper delegated permissions or a shared mailbox, granted by your IT team and removed when it’s no longer needed, never by sharing a password. That way client work continues when someone is on holiday or off sick, without weakening security or breaking the rules around who can see what. For an accountancy practice, where a delayed client email can mean a missed deadline, having a safe way to cover is important.

Sharing a login to cover someone is a common but risky shortcut. Here’s the secure way to do it.

1. Delegated access, not shared passwords

We grant a colleague proper delegated access to the mailbox, so they can read and respond under their own login. Nobody shares a password, which keeps the account secure and every action traceable.

2. The right level of access

Cover might need full mailbox access or just the ability to send on someone’s behalf. We set the right level for the situation, so the cover person can do what’s needed and no more.

3. Granted quickly when it’s urgent

Cover is often needed at short notice. Our helpdesk sets up access quickly, so an absence doesn’t leave client emails unanswered while someone is away.

4. Removed when it’s done

When the colleague is back, the cover access is removed, so permissions don’t linger as a quiet risk. Tidy access is part of keeping the firm secure.

A real example: cover sorted quickly

We support a London accountancy practice serving music and entertainment clients where a member of staff needed urgent access to a colleague’s emails while they were away. We granted the right delegated access quickly and securely, so client work carried on. As the user said: “Request sorted quickly, thank you.”

For a London accountancy practice serving music and entertainment clients, this is part of managed IT and security that usually costs about £45 to £100 per user per month, scaling with headcount, your hosted desktop or CCH setup, and the security your high-profile clients expect.
