So, the generic email I received from Marriott says that transfers from Ultimate Rewards no longer count as a qualifying activity.

Since point sharing, receiving(transfer) does not include in qualifying activity towards Points Expiration date, your date for point expiration is not extended further.

Here is the list I was given.Qualifying Activity

  • Activity based on Arrival Date
• Completed Marriott Bonvoy Events
  • Activity based on Departure Date

• MVW Owners exchanging week or Points
  
• Purchasing Points
  
• Converting Points to Miles
  
• Redeeming Points (including Charitable Donations)
  • Excluding hotel Awards and Travel Packages
