How can I filter messages in a Teams chat to a specific range accurately?

Question

I would like to get Teams chat messages in an API call, but filtered to a specific date-time range. For some inexplicable reason, the filter based on the message's createdDateTime property does NOT allow specifying a start/lower boundary (ie, greater than). It only allows upper boundary (end of range/less than). If you look at the documentation for it, the query parameters allowed for filtering are lastModifiedDateTime and createdDateTime. However, only lastModifiedDateTime allows specifying greater than (gt) and less than (lt). For createdDateTime, only less than (lt) is allowed. There is no explanation for why this is.

How can I accurately get messages that were sent within a specific date range? The lastModifiedDateTime gets affected if the user edits their message, if other users react to the message with emojis, etc. That opens too many possibilities of getting inaccurate results (ie, messages can either be missed or incorrectly included).

Hello Joel Silver,

Thank you for reaching out to Microsoft Support!

According to the documentation, createdDateTime supports only lt operators, as you stated.

After the query there is a parameter that uses search, I hope it is useful for you, please see the documentation for details:

Hope this helps.
