I would like to share a tasks folder with someone outside our organization but I get the attached error when I try.
I've added the email address as a contact in O365 Exchange and I can select the user from the Global Address List but I'm unable to assign permissions to allow that user to view and edit the task folder.
I found where I can add a domain to be able to share a calendar but nothing about any other folders.
It's not a cache issue, I select the user by clicking 'To:' and choosing the contact from there, not from autocomplete.
Anyone have a solution for me? Thanks in advance!
