How to eliminate Outlook OST Calendar from the OST file?

OST files can get duplicated due to several reasons,

Some of the most common ones include:

• Multiple Email Accounts: If you have multiple email accounts configured in Outlook, each account may create its own OST file, resulting in duplicate files.
• Synchronization Issues: Sometimes, synchronization issues can cause OST files to get duplicated. This can happen when the synchronization process is interrupted, or there is a problem with the Outlook data file.
• Virus or Malware Infection: A virus or malware infection on your computer can cause OST files to get duplicated, as well as corrupt or damage the existing files.
• Software or Hardware Errors: Errors in software or hardware components can also cause OST files to get duplicated. For example, an error in the Outlook application or a problem with the hard drive can cause duplicate files to be created.
• Manual Creation: In some cases, users may manually create duplicate OST files without realizing it. This can happen if they copy an existing file or create a new file with the same name.

Duplicate OST files can consume valuable disk space on your computer, leading to performance issues. Therefore, it is recommended to regularly clean up duplicate files and ensure that your Outlook data files are properly synchronized and maintained.

To eliminate the OST Calendar from the OST file in Outlook, you can follow these technical steps:

• Close Microsoft Outlook if it is open.
• Press the Windows key + R to open the Run dialog box.
• In the Run dialogue box, type "regedit" and then click OK. The Registry Editor will launch as a result.

Go to the following route in the Registry Editor:

• HKEY_CURRENT_USER\Software\Microsoft\Office\xx.0\Outlook\Options\Calendar

Note: Replace "xx.0" with the version of Outlook you are using (e.g., 16.0 for Outlook 2016, 15.0 for Outlook 2013, etc.)

• In the right-hand pane, locate the value named "DisableCrossAccountCalendarSyncing".
• If the value exists, double-click it to modify its value data to "1". If the value does not exist, create a new DWORD (32-bit) Value named "DisableCrossAccountCalendarSyncing" and set its value data to "1".
• Close the Registry Editor.
• Restart Microsoft Outlook. The OST Calendar should now be eliminated from the OST file.

Note: It is recommended to create a backup of the Registry before making any changes. Also, modifying the Registry can cause serious problems if not done correctly, so it is important to follow the steps carefully.
