Issue

When migrating Roommailbox bookings to Google Calendars, the migration Tool (GWS) sends RSVP notices to participants’ mailboxes which will cause a lot of confusion and Users keep receiving mailbox notifications for resource Booking.

To Fix this problem A content compliance rule can be set up in the Google Workspace admin console to quarantine such mail notifications.

Solution

Follow the below steps

1. Open Google admin console, URL www.admin.google.com
2. Go to Menu “”and then”” Apps > Google Workspace > Gmail > Compliance.
3. Select the Root OU (Domain name = Root OU)
4. Scroll to the Content compliance setting in the Compliance section, and Click Add another Rule.

1. Content compliance = Give a name for the rule, eg. Block resource calendar notification.
2. Select Messages to affect – Inbound and Internal -Receiving
3. Add expressions that describe the content you want to search for in each message
   • If all of the following match the message, and click ADD
   • Location: Full headers
     Contains text: @resource.calendar.google.com
   • Location: Full headers
     Contains text: ILARL

5.  If the above expressions match, do the following
Quarantine message = Default. (you can create your a quarantine space for different types of emails, refer article on how to create quarantine)
