I would like to build a flow that will create a task reminding me to follow up on an email that I have sent if the recipient has not responded within x days. I only want this flow to run against selected sent mail, not all sent mail.
Here's how I envision it working. I would select a sent message or a message that is being composed to trigger the flow. The MSFT gods would create a task titled “Follow up with <recipient> re email “ <subject>”. The task would have an immediate start date, a due date x days in the future, and a reminder on the due date at the same time the task was created. The system would then monitor my inbox, looking for an email with the same <recipient> and <subject> (unless there is a better way to track my outbound message). If no response is received by the deadline, the previously-created task would trigger. If a response is received, the system should record a note in the task like “Response received - task automatically deleted” and delete the task (or mark it complete if that is easier). That is, unless the task had already been completed or deleted, in which case no change would be made.
My initial thought was that I could achieve this by assigning a specific Category to the sent mail that I wanted to watch, but flow/automate doesn’t seem to be able to trigger based on Categories. I am at a loss as to how else to get started on this (I am a Flow newbie). Any suggestions greatly appreciated!
