This is my msRTCSIP-GroupingID editor. I use it to segregate addresslists in Lync solutions. It takes a commaseparated text file containing Company name and GUID for the addresslist assigned to this Company (filename : groupingids.txt) sample:
I have placed this file on the Lync share for my own convenience. Powershell script Groupingeditor.ps1 loads these values to a listbox. It let you search for users and then apply the groupingID to the selected users.
Next Version will contain possibillities to select entire OU’s and list users containing a spesific GroupingID.
When using booking assistent and roomlist meeting rooms does not always show in the list as expected. One reason for this is that user make a default invitation and by default the meeting time is this morning witch is already passed. Another thing is that default working hour for the meeting room is 08:00 to 17:00 – outside this the room will not show in the roomlist.
Use get-mailboxcalendarconfiguration to get workinghours for a room / mailbox.
