Hi @Carolina P ,
Thanks for your post in our forum. Based on my tests and research, the ability to set a custom reminder time for a meeting is not feasible in Outlook for mac currently.
If you would like to have this feature to be introduced to Outlook for Mac, we recommend you make a suggestion via this link.
Many features of our current products are designed and upgraded based on customers’ feedback. With requirements like this increase, the problem may well be released in the future.
Warm thanks!
