In Outlook 2016 some users may noticed dual entries in the Room List:
TheÂ roomÂ listÂ behavior that we seeÂ Â inÂ Outlook is by design. When weÂ use aÂ RoomÂ ListÂ Â for a meeting, itÂ is storedÂ inÂ theÂ Â Most Recently Used entriesÂ inÂ the registry. When we create a new meeting, we will see this MRU entryÂ inÂ the top of theÂ RoomÂ ListsÂ . The sameÂ RoomÂ ListÂ will be seen againÂ inÂ the drop down which is accessed from the Exchange Server/ Online.
To prevent theÂ duplicateÂ entries seenÂ inÂ theÂ RoomÂ List, create the below registry entry with blank data to disable theÂ Â Most Recently UsedÂ Â RoomÂ ListÂ inÂ Outlook.
If these entry already exist just empty the values.
After Outlook Restart:
Â Only single instance of the rooms list now showing! 🙂
