Attendees added to a meeting or appointment show “No information”
I had an Outlook 2010 problem where the user would add attendees to a meeting or appointment but their schedule would either show “No information” or it would endlessly try to read their data.
The attendees data and email showed correctly in there entries and sometimes they could be added and it would work alright.
I tried several repairs that are too long to list but the eventual fix was removing the names from autocomplete on the address line and letting them re-add. It has worked consistently since then.
