by the way ost file may broke any time


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.
