The email signature when an employee leaves is rarely the real problem. The problem is everything that still carries the person’s name: their mailbox, the address customers keep writing to, a shared inbox that signs off as them, and a template that still lists them. This page is a seven-step checklist for the admin who is handed a leaver’s name on a Friday and wants it tidy by Monday.
These steps follow Google’s help pages on deleting or removing a user and preserving former employee data, both showing “Last updated 2026-10-01 UTC”, and Microsoft’s Remove a former employee series, read in October 2026. None of these pages is about signatures. Where we add advice on the email signature when an employee leaves, it is ours, and we mark it.
Email signature when an employee leaves: the short version
- The email signature when an employee leaves ends with the mailbox: what they set in their own mail app goes when you suspend or delete the account. What is left is mail, shared inboxes and the roster.
- Route incoming mail before you delete anything. Microsoft says not to delete the account if you forward mail or use a shared mailbox.
- Put a handover line in an automatic reply, with a name and an address that will still work.
- Remove the person from any signature tool, and from shared mailboxes that sign in their name.
- Pick a date to switch the forwarding off, and write it in the ticket.
Where a name lives after an employee leaves
Before the steps, list the places a signature can sit. The email signature when an employee leaves behaves differently in each, and closing the account cleans up only some of them.
- The person’s own signature. Google’s page on user signatures (last updated 2026-10-01 UTC) says users can create a personal signature in their Gmail settings. That setting belongs to the mailbox, so it goes when the account does.
- A company footer. Google says an admin-appended footer is something users “can’t change or remove”. Microsoft’s page on organization-wide signatures (dated 7 May 2026) calls any such signature a “disclaimer”. Both are company text, so a leaver does not change them, unless the text names a person (a “contact Priya” line, say).
- A template or roster. If you keep the design in a separate tool, that tool has its own list of people.
- A shared inbox. An address such as accounts@ often replies in one person’s name. Nobody notices until that person leaves.
The same Microsoft page lists a limit that matters for step 6: its rules skip a line whose variable is empty, such as a phone number missing from the directory.
The seven steps for an email signature when an employee leaves
1. Block sign-in first
Do this at the agreed time. Google’s options page says suspending a user blocks access while preserving the data. Microsoft’s series starts the same way, with “Prevent a former employee from signing in to your organization’s Microsoft 365 services”.
2. Decide where the old address goes
Customers will keep writing to the old address for months. Pick one route before you touch the account. This table compares what the vendors’ pages describe.
| Route | Google Workspace | Microsoft 365 |
|---|---|---|
| Forward new mail | Advanced settings, “Redirect or forward Gmail messages to another user”, after you have preserved the data | Users > Active users > the person > Mail tab > Manage email forwarding > Forward all emails sent to this mailbox |
| Keep the old mail too | Transfer Gmail data to another user, or keep an Archived User licence (a paid licence, per Google) | Convert the mailbox to a shared mailbox, which needs no licence while it is under 50 GB |
| Keep the address alive | Add the old address as an alias on another user (Google’s page suggests an alias instead of deleting) | Forward, or use the shared mailbox |
| Time limit | The address is removed 20 days after the account is deleted; you can reassign it before then | Deleted mail and OneDrive content are kept for 30 days |
Two warnings come straight from the pages. Microsoft says that if you use forwarding or a shared mailbox, you should not delete the former employee’s account, because the account anchors it. And Google says that on annual or fixed-term plans, deleting an account does not reduce the number of licences or affect billing.
3. Set an automatic reply with a handover line
This is the visible part of the email signature when an employee leaves, because senders see it first. In Microsoft 365, the page on setting replies on another user’s mailbox (dated March 2024) gives this path: Users > Active users, pick the person, then Mail settings > Automatic replies. For Google Workspace we did not open a help page on this, so we give no menu path. Check Google’s help for your edition.
4. Fix shared mailboxes and groups
Search for the person’s name in shared inboxes and group descriptions. Give each shared address a role signature, which names the team and not a person. Microsoft’s page lets you set automatic replies on a shared mailbox too, so the handover line can live there.
5. Remove the person from your signature tool
If your signatures come from a design tool with its own roster, remove the leaver there, as part of the same email signature when an employee leaves checklist. See the section below for what emailfooter does.
6. Update the people who inherit the work
The email signature when an employee leaves may also change for the people who take over. The successor may need a new title, a new direct number or a second department line. Do it as you would for a new joiner, using the new employee signature setup checklist.
7. End the forwarding on a date
Forwarding is a bridge, and the email signature when an employee leaves is only finished when the bridge is taken down. Write an end date in the ticket and put a reminder on it. The right number depends on how quickly your customers move to the new contact, so treat 30 days as a starting point, not a rule. After that date, a message to the old address should get a clear bounce or the auto-reply, not silence.
A handover line for the email signature when an employee leaves
This is our own wording, with made-up names. A handover line belongs in the automatic reply and, if you like, in the successor’s signature for a few weeks. Keep it short, name one person, and give an address that exists.

Three rules keep it honest:
- Say the person has left. Do not say “on leave” when they are not coming back.
- Name a role or a person who really covers the work today.
- Do not promise forwarding unless step 2 is switched on. “Your message will be passed on” is a promise.
A role signature for the shared address
The email signature when an employee leaves often hides in a shared inbox. When it used to sign off as Priya, change the sender block to the team. The drawn example shows a role signature with the company’s main number and no personal photo.

A role signature tells customers they are writing to a team, and it means the next hand-off needs no edit.
What emailfooter does with the email signature when an employee leaves
emailfooter is the free WordPress plugin we make. These facts come from its code and screens in version 1.2.0, not from a vendor help page.
- The People screen lists each person’s name, email, role and joining date, and lists open invitations, which an admin can revoke. We found no button there that removes an existing person.
- When a WordPress user is deleted, the plugin deletes that person’s company memberships (it hooks WordPress’s user-deletion event). A share link that person made then returns “This link is no longer active”.
- emailfooter does not push signatures into mailboxes. People copy theirs into their own mail app. So removing someone from emailfooter does not stop a signature already pasted into a mail app. Closing the mail account does.
If you want a company-wide footer that no one can edit, set the legal footer under Business info. The plugin says employees cannot remove it. See company email signatures for the wider design choices.
Common mistakes with the email signature when an employee leaves
- Deleting first. If you plan to forward or share the mailbox, deleting the account breaks the plan, per Microsoft’s page.
- Forgetting the alias. A leaver’s address gets reused for a new hire with the same name, and the new person receives the old person’s clients’ mail. Decide the naming rule in advance.
- Leaving the name in the footer. Search your appended footer and your template for the person’s name or number.
- No end date. Forwarding that never ends becomes a second inbox nobody owns.
A short list is easier to keep than a long policy. Put these seven steps in your offboarding ticket, and the leaver clause of your email signature policy gets a procedure behind it.
Frequently asked questions
What happens to an email signature when an employee leaves?
The signature they set in their own mail app stays with the mailbox and ends when you suspend or delete the account. A company footer is not affected. Check shared inboxes and any design tool that holds a roster.
Should I delete the account or keep it for the email signature when an employee leaves?
Keep it while you forward mail or use a shared mailbox. Microsoft says the account has to remain for those options. Delete it once the data is transferred or no longer needed, remembering Google’s 20-day and Microsoft’s 30-day recovery windows.
Do I need an automatic reply as part of the email signature when an employee leaves?
It is the simplest way to tell senders the person has gone and who to write to. Keep it short, name a person or role, and make sure the address works.
How soon should the email signature when an employee leaves be removed?
Block sign-in at the agreed leaving time. Then work down the list in the same week. Our email signature audit guide shows how to check a month later that nothing old is still going out.
