How OST file becomes inaccessible?
When ost file is created, an encryption key is generated which binds the file with the profile for which it is made. This encryption key protects OST file from being accessed by other profile. So, if in any case profile to which ost file belongs, is deleted then, user will not be able to access ost file. This will make OST file orphan. And when you will try to open orphan OST file, outlook will report an error. Thus making it inaccessible. Another main reason is OST file synchronization error.

Other reasons such as virus intrusion, or file size issues may leads to inaccessibility of OST file in Outlook.
