Recreate an offline Outlook Data File (.ost)

Some account types, such as Microsoft Exchange Server, use an offline
Outlook Data File (.ost). This type of data file is a copy of
information saved on your mail server. If you encounter problems with an
offline Outlook Data File (.ost), the file can be deleted and recreated
by downloading a copy of your items again. We don't recommend repairing
an offline Outlook Data File, so if your offline data file isn't usable,
you should recreate it.
