Hi,

 

For how long is chat history kept for in Microsoft Teams? I know with slack it keeps 3months unless you pay for it,

 

Kind Regards,

Judah

I'm not aware of any official document describing for how long chat history is retained. At least it does not appear in the Teams FAQ: https://support.office.com/en-us/article/Frequently-asked-questions-about-Microsoft-Teams-%25E2%2580...
Hi Juan, who should I speak to about this, or is there somewhere else I can find the answer?

Kind Regards.
Judah

Right now it is kept in perpetuity. Forever :)

 

@Ansuman Acharya might be a good person to talk about this.

Solution

Well, technically if you want/need to preserve it indefinitely, you best put the Group/Team on hold. Otherwise it might be possible to delete it, by mistake or deliberately. But yes, as it's stored as part of the Group, there are no limits on it, that we know of.

Thanks @Vasil Michev @David Rosenthal for responses, that's all I needed to hear :)

Hi all. I have just returned from holiday, am looking at my 'Chat' in Teams and my old Chats have definitely dissapeared. To be clear these are Chats, rather than conversations within a Team.

Is there any clarification of how long these chats are retained for?

 

Thanks, Laurie

@Laurie Willis,

 

Have you noticed that in chats there is a Recent option:

recent.PNG

This would indicate that there is also a not recent view of the chats. However this options doesn't seem to be there.

 

Then I tried to search for one of the people that I had a chat with and the older conversations came up.

 

So it looks like by default you only see the last 2 weeks, but search shows all.

Hi.

 

Yes I did notice this, but couldn't see a way of seeing 'non-recent' chats. If I do a search it just seems to return results from all conversations and I can't filter down to chats. Do you get the same?

 

Thanks, Laurie

 

You should see the last 4 weeks of "Active Conversations" - that is if there is constant posting in  channel you will see the last 4 weeks of that thread in the channel.  However, I am noticing this is not the case.  It is more like 24 hours of history is being kept.  In one case I noticed that threads were missing from the same 24 hour period.  If you searched for them by username or by text in the thread you would find the conversation but it was definitely missing when just viewing in the normal channel view by scrolling up to see the history. 

I've opened a ticket with PSS and they have confirmed this is an issue with multiple tenants but have not given an ETA to resolve it.  Will post again here as I get further info.

Has anyone come across a definitive answer for this retention in chat history and in channel conversations?

Microsoft has released the policy to set the chat history.

  • Deletion: Delete Teams data after a specified duration

Teams Retention Policies do not yet support:

  • Advanced Retention policies don't apply to Teams chat and Teams channel message locations
  • Duration of fewer than 30 days
