Google Workspace: a group as a Collaborative Inbox
In Google Workspace, a shared inbox is a Google Group with Collaborative Inbox turned on. Members can take a conversation, assign it to someone else with an optional note that is emailed to them, and mark it complete, no action needed or a duplicate. You filter by “Assigned to me” or “Not assigned” from the search bar, and you work in Google Groups rather than Gmail.Google
- An admin turns on Groups for Business and, under Apps > Google Workspace > Groups for Business > Sharing settings, ticks “Group owners can allow incoming email from outside the organization”. It is unticked by default.Google
- Create the group in Google Groups with the support address and add the people who answer. Collaborative Inbox needs conversation history on.
- In Group settings, under “Enable additional Google Groups features”, select Collaborative Inbox.Google
- Set Who can post to everyone on the web, or customers’ mail bounces, and give members the “Who can moderate content” and “Who can moderate metadata” permissions the take, assign and resolve actions need.
The other Workspace option
Delegation: make support@ a user and let others open it from their own Gmail. A Workspace account can have up to 1,000 delegates, with about 40 at once in normal use, and your admin must have delegation turned on.Gmail It needs a user, and so a licence, for the address, and it has no take or assign.
Microsoft 365: a shared mailbox in the admin center
In Microsoft 365, a shared mailbox needs no licence of its own while it holds up to 50 GB; each person who opens it needs their own licensed Exchange Online mailbox. Past 50 GB, or for archiving or litigation hold, it needs an Exchange Online Plan 2 licence. Microsoft supports up to 25 users on one shared mailbox, and Microsoft 365 Apps for business has no email, so it cannot have one.Microsoft
- As an Exchange admin, open the Microsoft 365 admin center and go to Teams & Groups > Shared mailboxes.
- Select + Add a shared mailbox, enter a name, check the address and select Save changes. It can take a few minutes before you can add members.
- Under Next steps, select Add members to this mailbox, then Add members, and pick who answers.Microsoft
- Decide how replies look: Send As makes a reply come from the mailbox, Send on Behalf shows “Sam on behalf of Support”. Sign-in to the mailbox itself stays blocked.
With automapping on, which is the default, the mailbox appears in each member’s Outlook after a restart, and it can be added to the Outlook app on iOS and Android. Anyone can delete a message in it; Microsoft points to a Microsoft 365 group if you need to stop that.Microsoft
Free Gmail: one support account with delegates
Free Gmail has no shared inbox, but delegation gets close: a personal account can have up to 10 delegates. Add them on a computer under Settings > See all settings > Accounts and Import > Grant access to your account. It can take up to 24 hours to work, the invitation expires after a week, and a delegate cannot change the password or use Chat.Gmail
When a delegate sends, their own address appears on the message, and there are no owners or statuses, so use a label per person. The address also ends in @gmail.com; for support@yourdomain.com you need your domain’s mail handled somewhere.
Zoho Mail and host email
Zoho Mail has shared mailboxes under Admin Console > Groups > Shared Mailbox > Create. Set “Who can send emails to your group” to Everyone so customers can write in. Mail to it stays out of members’ personal inboxes, and external members cannot be added.Zoho
Hosting email in cPanel has forwarders (Forwarders > Add Forwarder), which can send support@ to several addresses at once.cPanel That gives everyone a copy, not a shared inbox: each person answers from their own mailbox and nobody sees who already did. Forward to one shared inbox instead.
