I have a staff who must click to show hidden chat content in individual chats with another staff. We have a company retention policy of 1 year, however the chats are only 2-3 weeks old. Is it possible to reset this per account to get it working as expected?

    Okay yes I just saw this in my own environment and was tinkering around wondering when this happens or why. I finally discovered it. This didn't happen before recent updates, but now, if a user "hides" a conversation then goes back to it or someone sends a message in it, it will by default hide past conversations and give you that message you referenced. If the user unhides or doesn't hide the conversation, this doesn't happen. So this is due to the manual step of the user hiding a conversation and not retention. I verified this myself on my computer.

    Hope this helps!

    Hi @AdamYV

    I am not sure your meaning of reset Teams chat history. Do you mean you want to delete the previous chat history or archive chat history?

    If you want to see these chat and don't want to hide it, you could select Teams Chat Bubbles icon to open the chat list. Find the name of the conversation you want to pin. Then, select More options More options button > Pin. This ensures that the chat stays at the top of your list. If you change your mind, just select it again and unpin it.

    Setting up Retention policies for chat will help in my opinion.
    Follow the steps below to set a retention policy for chat for individual/selected/all users

    1. From the Microsoft 365 compliance center, select Policies > Retention.
    2. Select New retention policy to start the Create retention policy configuration, and name your new retention policy. For the Choose the type of retention policy to create page, select Adaptive or Static, depending on the choice
    3. If you chose Static: On the Choose locations to apply the policy page and select Chat as follows. Select your choices for users to be selected.

    4. On the next page, you can select the retention time needed and other choices as you are looking for

    I fear no-one is understanding the issue.
    I'll try again:

    ISSUE WITH TEAMS APPLICATION: CHATS with Individuals are automatically hidden (MUST click to reveal)
    There is a 1 year retention policy - HOWEVER - the chats are less than 1 year old

    Has anyone resolved this issue before?
