Situation where tasks in Outlook shared with another user which has worked great for years. Now it's beginning to have sync issues. I expect this is due to the size of the OST file increasing because if it's deleted tasks sync for awhile then begin to fail.
Moving to Microsoft 365 and would like to continue sharing tasks if it works. If it doesn't is anyone aware of an Office 365 service, add-in, product similar to sharing tasks with others users in Outlook?
We also have ToDo now as part of O365.
