Let’s analyze each scenario based on the given retention policies and Microsoft 365 documentation.
???? Policies Recap
Policy1
Teams channel messages → All Teams → Retain 7 years → Delete automatically.
Teams chats → User1 → Retain 7 years → Delete automatically.
Policy2
Teams channel messages → Team1 → Retain 5 years → Delete automatically.
Teams chats → User2 → Retain 5 years → Delete automatically.
???? Reference: Retention policies in Microsoft Teams
???? Statement 1: The message edited by User1 will be deleted after five years.
Location = Team1 channel.
Policy1 applies (7 years for all Teams).
Policy2 applies (5 years for Team1).
Conflict rule: For retention, the longest duration wins.
Therefore, the message stays 7 years, not 5.
✅ Answer: NO
???? Statement 2: User1 can see the message sent by User2 for up to seven years.
Location = Private 1:1 chat (User2 → User1).
For User1’s mailbox: Policy1 applies (7 years).
For User2’s mailbox: Policy2 applies (5 years).
Retention in Teams chats is per-user, so each participant may have different durations.
For User1, the retention is 7 years.
✅ Answer: YES
???? Statement 3: The message deleted by User1 will be moved to the SubstrateHolds folder.
Location = Team2 channel.
User1 deletes the message, but retention policy (Policy1) applies (7 years).
Retention overrides user deletion: message is moved to the SubstrateHolds folder in the hidden mailbox for preservation.

✅ Answer: YES
