Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi, kuaci
Good day!
Thank you for posting to Microsoft Community. We are happy to assist you.
According to your description, the issue of your concern that you keep receiving the reminder emails.
First of all, may I know that how did you set your Outlook to send the reminder emails? (Please share it steps by steps with us that we can find a way to disable it.)
Or there's an easiest workaround for you that you can right click this email and select Junk > Block Sender.
And these annoying emails will go into your junk folder and won't bother you anymore.
If you're willing to use Reminder emails again, please be kindly to share the details of the procedures that how did you set up it or as from the screenshot, its generated from Power Automate, so we also recommend to kindly check this query with Power Automate community site by posting your question on Microsoft Power Automate Community - Power Platform Community, so support expert from Power Automate can check and also suggest steps if its required to do from that site. At this point, your kind cooperation will be highly appreciated.
We're glad to assist you and looking forward to your new updates.
Thanks for your precious time and have a nice day.
