Filter Emails That Do Not Have An Assigned Category Using Graph API

Bryce Mowat 25 Reputation points

Hello, I am fairly new to using Graph API.

Currently, I am using Power Automate to triage emails landing in a shared mailbox, to move them to specific subfolders for actioning.

Occasionally, an email will need to be moved back to the inbox. However, before being moved back to the inbox, these emails will be categorized for specific employees to action.

To prevent the automation rule from running again on previously processed emails, I want to set up a HTTP GET request that filters only those emails in the inbox that do not have an assigned category. How would I do this?

    Hi @Bryce Mowat

    You can retrieve messages without any categories by filtering the categories attribute. You can also use the $count query parameter to count the set of messages returned.

    GET$filter=not categories/any()&$count=true

    Hope this helps.
