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.

    Hi,

    it’s me again, maybe you shoud use these foldernames:

    TASKKILL /F /IM “outlook.exe”
    del “%userprofile%\AppData\Local\Microsoft\Outlook\*.ost”
    rd /s/q “%userprofile%\AppData\Local\Microsoft\Outlook\Offline Address Books”
    rd /s/q “%userprofile%\AppData\Local\Microsoft\Outlook\RoamCache”

    regdards, Frank
