Delete OST file – Outlook 2010 and Outlook 2013
Often times Outlook issues are solved by simply deleting and recreating the OST file so I made a quick script for our helpdesk folks to get rid of OST file, clear OAB and Remove the Outlook RoamCache folder containing address Autocomplete files.
BEFORE YOU PROCEED: These steps should only be performed by an Administrator who understands the implications of running it.
You could create a BAT file and name it – Delete OST
Once these commands are run, Outlook will start downloading mailbox from the server.
