I had followed this to try to segment my address list. I had used EMS to create second Global list based on query usermailbox and attribute5. I had apply this new gal to only me.
Once log on to OWA, I only saw newly GAL. Once I manually delete it from EMC, now appeared this newly GAL was assigned to all users.
How to change to default GAL in OWA
Please help it is urgent
