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.
