Not able to publish official brand kits

The most likely issue is that the Enterprise Brand Manager policy isn’t fully configured in the required way, even though the publish button is visible.

Check these items in config.office.com:

1. Open Customization > Policy Management.
2. Select the policy used for Brand Manager.
3. Verify the Elevated role for Brand Managers policy is Enabled.
4. Verify the Security group email address is the correct mail-enabled security group for the brand managers.
5. Verify the policy scope is Tenant / Apply to all users.
6. Verify the policy priority is set to 0.

The documented required configuration is:

• policy scope set to Tenant
• policy priority set to 0
• correct brand managers mail-enabled security group configured

Also verify the group membership:

• Only members of the mail-enabled security group get publish and edit access to official kits.
• Owners only of the group do not get official kit editing and publishing access.

One more timing check:

• After designation as a brand manager, permissions can take up to 24 hours to apply.
• Since this has been almost a week, that points more strongly to a configuration issue rather than normal propagation delay.

If the button is present but stays disabled with “we’re setting this up for you”, the first things to recheck are:

1. the group is mail-enabled,
2. the account is a member of that group, not just an owner,
3. the Brand Manager policy is Enabled,
4. the policy scope is Tenant / Apply to all users,
5. the policy priority is 0.

Once those are correct, designated brand managers should see the publish option become available for organization-wide sharing of official brand kits.
