Just close Outlook and delete/rename old OST file. Then start Outlook and it will create OST again by retrieving all data from your account (IMAP/Office365/Exchange/..).
Or just create a new Outlook profile for your account.

Using scanpst.exe utility you can easily repair your corrupt OST file.I tell you the entire process of scanpst.exe.First, close to “Microsoft Outlook” before using Inbox Repair Tool.
Now follow these simple steps:
Step1: Double click on SCANOST.EXE.
Step2: If your Outlook application is running then it will ask you to close it.
Step3: Else, a new window open i.e OST Integrity Tool. If the tool asks for Profile name then provide the accurate name.
Step4: Now, if you will see a message Connect or Work Offline then click on Connect.
Step5: Select an option according to your priority either Scan all folders or Choose the folder to scan and click Begin Scan.
Step6: Once the scanning process completed you will receive a message OST repaired successfully.
I hope helps it
Thank you!!

There are quite a few solutions with which you can repair your OST files.
One solution is to update your folder. You can right click on the folder and then properties. A dialog box appears and under this dialog box, click the clear offline items option. Then click OK. Now, on the outlook ribbon, go to the send/receive option and click update folder.
Another solution that you can use scanpst. You can run scanpst.exe and then it will check for errors and it would repair them. If the files can’t be repaired it will recreate it.

Microsoft Outlook 2010 doesn’t support manually opening or importing items from an offline Outlook Data File (.ost).
Note: By default, when you add an account that uses an offline Outlook Data File (.ost), the file is automatically created and data from the server is downloaded. Also, if you specify a new folder location for the offline Outlook Data File (.ost), a new file is automatically created. Although not required, you can manually move the existing file to the new folder to avoid the download time that is required to re-create the file. For more information, see Move an Outlook data file.
Outlook Data Files (.ost) are used when you have an Exchange account and want to work offline or use or use the default Cached Exchange Mode. This type of data file is also used for accounts that you set up with the Outlook Connector for Outlook.com (formerly Hotmail). Outlook Data Files (.ost) are always copies of items that are saved on a mail server and don’t need to be backed up like Outlook Data Files (.pst).
Re-create an offline Outlook Data File (.ost)
Offline Outlook Data Files (.ost) are copies of your Exchange information. It is not necessary to back up this file. You can create a new copy at any time.

# Case 1: If the Original MS Exchange Account Has Not Been Changed
Users can follow this approach if they can start the MS Exchange application offline using the old PST file. In this approach, you can recover mailbox from OST file by converting them to PST file.
Follow these steps to restore mailbox from OST & extract emails from them:

Wrapping Up
Open Ost File Outlook 2013
If the situation is favorable, retrieving a mailbox using an OST file can be a simple and straightforward process to perform. But, if there are some challenges like OST file or the Exchange Server is corrupted, then it does not make any sense to go for these workaround solutions. For the complicated cases, it is suggested to employ automated solution given above. The approach makes it easy to recover emails from OST file in 2016, 2013, 2010, 2007.
Oftentimes, Microsoft Outlook users who are leaving their current employer want to take their mail, calendar, or contacts with them and do one of two things: delete the Microsoft Exchange account from their profile without realizing the Contacts are stored in the Exchange account or they take the OST file with them, not realizing it can only be opened using the account that created it.
If you have the OST file but no longer have access to the computer that created the OST or you don't have a restore point, you'll need to use a tool to recover the contents of the OST. A list of these tools is below.

Beginning with Outlook 2013, Outlook was designed to permanently delete the OST data file when the account is removed from Outlook. If you deleted the account from Outlook and did not export the contents to a pst file or copied the OST file, your chances of recovering data is not good. You will need to use software to undelete files from your hard drive, but successful recovery depends on how much time has passed between deleting the account and running the undelete software as Windows will overwrite the deleted files. To see if the OST exists, type or paste %localappdata%microsoftoutlook into the address bar of File Explorer. Many of the companies that have OST to PST recovery software also have file recovery software.
There are number of file recovery programs available, including these utilities from our sponsors: DataNumen NTFS Undelete (Free), DataNumen Data Recovery, Kernel for Windows Data Recovery, and Stellar Phoenix Windows Data Recovery
If your company uses a group policy that blocks PST creation, your choices are limited to exporting calendar and contacts to CSV (or Excel, if you have Excel at home). If you don't have many calendar or contacts, you can forward them to a personal address. If using Outlook 2007 or newer, you can send your entire calendar as an iCal.
Check company policies before taking home the contents of your mailbox.
Restore Exchange Account
If you deleted the Exchange account, you may be able to recover the account if your operating system supports system restore and you only recently deleted the account. If too much time has passed you are less likely to have a restore point available.
This method will also work with IMAP accounts in Outlook 2013 and up IF you have a copy of the IMAP data file.
Outlook 2013 and up automatically delete the account's OST file when the account is removed from Outlook. The only way you'll be able to use this method is if the OST file exists (because Outlook failed to delete it. It's rare, but it does happen.) To check, look for the OST at %localappdata%microsoftoutlook before doing a restore.
- Open the System Restore application. In Settings or the Search field on the taskbar or Start menu, type restore then select Create a restore point in the search results. Click the System Restore button to open the System Restore wizard. You can also open it by typing or pasting rstrui.exe in search field or in the Run command.
- Pick a date just before the profile was deleted then follow the steps in the wizard.
When Windows restarts the account will be back and you can move or export the contents of the OST to a PST. Then either delete the account or run restore again to return to the point made before the restore, after backing up a copy of the newly created pst file.
Method 1: Archive
You may be able to use Archive to move or copy many items to a PST. Users Exchange online archive mailboxes will not be able to archive to a pst.
Autoarchive works best when you want to move almost everything in your mailbox, however, you cannot archive Contacts. You'll need to move or copy contacts to the pst file or use Export.
Set the AutoArchive default in File, Options, Advanced, AutoArchive and apply the settings to all folders. (The AutoArchive button the Folder ribbon allows you to set a specific archive setting for the current folder.)
Then go to File, Tools, Cleanup, AutoArchive to run it.
AutoArchiving uses the last modified date so you'll need to use a low number of days when archiving recent items. In Outlook 2007 and newer, you can force AutoArchive to use the Received Date. See Using Microsoft Outlook's Autoarchive feature
If you use this method and also need the Contacts, you'll need to move them to the new data file.
Method 2: Export to a PST
Although Export is not usually recommended, it works well for moving content from an OST to a PST file. You can export all content from the OST to a PST or just the calendar and contacts. If your company blocks the creation of PST files, export Contacts, Calendar, and Tasks to CSV or Excel format.
You'll use this method if you are moving to a new server and need to migrate your own email (or if the server died and there are not backups). Make sure you start Outlook offline so that you don't connect to the new server; connecting to the new server has the potential to delete the mail in the offline file. Export everything to a pst then remove your account and use auto account setup to add it back to your profile.
Method 3: Move the items to a new PST
Create a new PST in your profile and drag the folders you want to take with you to the PST. This method will preserve custom views and forms published to folder.
Dragging default folders, such as Inbox, Calendar, and Contacts, brings up a message that you can't move default folders. The contents will be copied instead, with the folder named Inbox (1), Calendar (1), etc.
Method 4: Forward by E-mail
If you don't have too many items you want to keep, you can email them to your personal email address. Select the item(s), right click and choose Forward or click Ctrl+F. If you have a lot of messages you want to keep, you could drag them to a folder in Documents, then zip the folder and email the zip file.
If you forward the messages to an account that is opened in Outlook, you can drag attached messages from the incoming message and drop it in the Inbox or another folder.
If you are using Outlook 2007 or newer, you can email the entire calendar as a single iCal, provided you use Outlook or another calendaring application that supports multi-event icals at home. Outlook 2003 and older versions of Outlook do not support multi-event icals.
Backup Ost File Outlook 2013
To create the iCalendar file, you can right click on the Calendar folder and choose Share, Email Calendar. If you want to create the iCalendar file and do something with it later, select the calendar folder, then go to File, Save Calendar.
When you use Email calendar, a dialog will let you choose the date range and other options. If you are saving the calendar to your hard drive, click More Options in the Save as dialog to open this dialog.
The defaults are Today and Availability only; you'll most likely want to use whole calendar and full details. Note that some calendars don't support attachments; if you are including attachment you should save a second copy that does not include attachments.
OST to PST export utilities
If you have an orphaned OST and can't recover the account using System Restore, you'll need to use a utility to export the contents to a pst file.
The free OST2PST utility will only work with OST files created by Outlook 2002 and older. If you aren't sure what version of Outlook you used, try it; an error means the OST is not the correct type.
