Hello We have recently moved some people to Exchange 2010 from 2007. One of them is saying that she is getting duplicate Calendar entries in her mailbox which makes it really hard to work with. Initially, we thought it was an issue with cached mode/OST file, so we switched her to Online, but she is still getting this issue. Same happens in OWA. Does anyone know a good way to: i. Remove the duplicates ii. Stop this happening again

Remove the duplicates There's no "good" way to do this. You can restore a backup to a recovery storage group and then remove all the items from the calendar in the active mailbox and them replace them with the items in the mailbox you restored -- but that loses the meetings/appointments made since the backup. So maybe sort the appointments by data and remove only those prior to the onset of the problem and then replace the same date range from the restored mailbox. Otherwise it's a manual task to manage this. >ii. Stop this happening again Is there a mobile device acting on the calendar? Some other client that's possibly "echoing" the appontments back to the Exchange server? --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

If the duplicates were created all at once, then the easy way to remove them is to use the "Created" date. Change the view in the calendar to Category/List View and then add the field "Created". The duplicated contacts will have the same creation date. Simon.Simon Butler, Exchange MVP Blog | Exchange Resources | In the UK? Hire Me.
