I’m still attending a weekly meeting for a project I handed over months ago

My contribution to Tuesday’s meeting was, “Nothing from me,” followed by fifty minutes of listening.

I used to coordinate this project. A colleague took over four months ago, and she now handles the suppliers, schedule and decisions. I’m still on the recurring invitation because occasionally somebody asks where an old document came from.

I can usually answer those questions after the meeting. Meanwhile, I have another project whose planning call overlaps with the second half. I keep leaving one conversation early to join another late.

The project lead says it’s useful to have me there “just in case.” I don’t want to sound as though I’m refusing to help after the handover.

How would you propose leaving the regular meeting while remaining available for the history I actually know? What would make the change clear enough that I’m not simply absent next Tuesday?
