A tour of Admin for workspace administrators

What each Admin tab does, how usage and limits are shown on Overview, and where to start with a new workspace.

Updated Nov 12, 2026

Admin is where administrators run the workspace. Only people with administrator access see it. The tabs run across the top.

The tabs

  • Overview: your plan, usage and a quick start.
  • Domains: connect and verify the domains your mail uses. See Connect your domain.
  • Users: create mailboxes and manage people. See Users and mailboxes.
  • Groups: group addresses, forwarders and shared inboxes. See Work a shared inbox.
  • API keys: access for apps, scripts and AI agents. See API keys and AI agent rules.
  • Sending: whether mail to outside addresses can go out. Shown when relevant. See Sending status.
  • Mail processing: a health page for each mailbox.
  • Security: sign-in and sharing rules. See Security policy.
  • Single sign-on: your company's identity provider. See Single sign-on.
  • Fraud shield: protection against payment fraud. See Fraud shield.
  • Apps: add "Sign in with PGB Business" to other tools.
  • Vault: set up the vault organization. See PGB Vault.
  • Import: bring mail in from elsewhere.
  • Compliance: retention, legal hold, data protection rules and eDiscovery. See Retention and legal hold and Data protection rules.
  • Data export: a full copy of workspace data. See Export workspace data.
  • Audit log: who changed what and when. Filter it by person (email). Load more shows older entries.
  • Plan & limits: plan, billing, storage and add-ons. See Plan, billing and storage.

You can switch tabs with the arrow keys.

The Overview tab

It shows your Plan and meters for:

  • Mailboxes and Domains. Domain aliases do not count.
  • Storage allocated: the total of every mailbox's size limit. It is how much of your storage pool is promised to mailboxes, not what they hold. When it runs out, lower some size limits in Users, Manage, or add storage on the Plan tab.
  • AI requests this month.
  • Emails to outside addresses today: counts each outside recipient, not each message. Mail between your own domains does not count. It resets at midnight UTC.

It also has Connect a mail app settings for Outlook, Apple Mail, Thunderbird or a phone, and Connect a domain if you have none.

Mail processing

This page needs no action normally. It shows, per mailbox, when new mail was last looked at and the last problem if there was one (quote it to support).

First-week checklist

  1. Connect and verify your domain.
  2. Create users.
  3. Turn on two-factor for everyone in Security.
  4. Turn on the fraud shield.
  5. Set up single sign-on if your company has an identity provider.
  6. Check the Audit log after changes.

Tips

  • Give administrator access to as few people as you can.
  • Hover the information icons in Admin. They explain what each switch does.
