Hello Experts - I'm working on ironing out my SharePoint site and ran into an unusual problem. When my manager logs in and wants to grant rights to staff for a specific page (she is a SP admin) she'll go to the relevant section, add the "allstaff" group by typing in the line which subsequently resolves to her username instead of the allstaff group. The same thing happens if she browses the directory and adds the allstaff group that way. The screenshot below is where the problem appears. When I type in "allstaff" and clieck the Check Name button it resolves normally. When she does it her name appears in place of the allstaff group. Very odd...I checked AD and Exchange, both look fine and this only happens on the SharePoint site.
Any ideas on what might cause something like that to happen?
