Org Owners and Org Admins can manage who can invite guests to workspaces in their organization and set a maximum expiration period to make sure membership stays current.
Choose who can invite guests
By default, Workspace Owners and Workspace Admins in an Enterprise Grid organization can invite guests to their workspaces. If you'd like more control over who can invite guests, choose one of the following options:
Org Owners/Admins only
Org Owners/Admins, plus Workspace Owners/Admins
Org Owners/Admins, plus select members
Note: Members who do not have permission to invite guests to your org can still request invitations. When invitation requests are approved or denied, members will receive a message from Slackbot to let them know.
From your desktop, click your workspace name in the top left.
Click Settings & administration from the menu, then choose Organization settings.
From the left sidebar, select Settings. Then, click Organization policies.
Click the Permissions tab.
Next to Guest Management, click Add Policy.
Choose who can invite guests.
Click Save Policy, then Create Policy to confirm.
Set a maximum guest expiration period
Org Owners and Org Admins can set a maximum expiration period for guests to determine when their access to Slack will end. Maximum expiration periods apply to guests invited by members, but Org Owners and Admins sending invitations can choose a longer expiration period if they'd like.
From your desktop, click your workspace name in the top left.
Click Settings & administration from the menu, then choose Organization settings.
From the left sidebar, select Settings. Then, click Organization settings.
Next to Maximum expiration for guests, click Edit.
