Limitations with multiple domains

When you add a domain to your Google Apps account, you need to keep in mind some limitations so that you can set up the primary and secondary domains correctly. The following topics discuss different features for primary and secondary domains:

Google Apps uses the name of your primary domain as the name for your organization as a whole. This is the organization name referenced in the sharing options that users see. When you add other domains, you might want to change your organization name to a more inclusive name.

Google Admin console:

  • You can't set different policies or configuration settings for different domains. All settings in the Google Admin console apply to all domains that are part of your account.
  • You can specify only one logo for your domains. The same logo appears for users in all domains that are part of your account.

Domain names and aliases

  • Google Apps account merge is not supported. Some current Google Apps customers with multiple domains have separate Google Apps accounts for each domain. Google does not currently support merging multiple Google Apps accounts into a single multiple domain account.
  • Migration from domain aliases is not supported. Some current Google Apps customers use domain aliases for their non-primary domains. Google does not currently support the conversion of domain aliases into multi domain accounts.
  • In the legacy free edition of Google Apps, secondary domains are not supported. The legacy free edition of Google Apps only supports domain aliases. All the other restrictions tied to domain aliases apply.

Account access URLs

  • You cannot create a global URL for accessing Google Apps. Users access Google Apps with a URL that includes the domain name from their email address, for example You can't provide a global URL that users from all domains share.

Google Calendar

  • Secondary domain users can't use the link in a calendar sharing notification email. When a user shares a calendar with users in a secondary domain, the users in the secondary domain can't click the link in the notification email to add the calendar. They must enter the shared calendar address in the Add a co worker's calendar box to add it.

Google Drive

  • You can't restrict sharing to users in a single domain. Sharing options are based on the organization as a whole (or organizational units with some Google Apps editions), not individual domains. With Google Apps Unlimited, Google Apps for Education, or Google Apps for Nonprofits, you can create an organizational unit for everyone at a particular domain and then restrict sharing for that organizational unit.

    To share a document with the users in a single domain (or any other subset of users), create a Google Group that includes all the users and share the document with that group.

Google Sites

  • Searches for sites return sites only in the same domain as the user. For example, a user with an address in a secondary domain will not find sites created in the primary domain.
When you delete a secondary domain, all sites created on the domain are also deleted. To avoid data loss, copy all sites on the domain you plan to delete to other domains. For details, see Transfer a website to Google Apps.

Google App Engine

  • Applications that use Google App Engine are not available for users at non primary domains.
