How To Increase Size Limit Of Your PST And OST Files In Outlook?

By default, starting from the Outlook 2010 version desktop application is able to open .pst files and create .ost which size is not more than 50 GB. If you try to open the .pst file which is more than 50 GB in size, you will receive the following error:

Error

In order to increase the maximum size of the .pst and .ost files that your Outlook can open or create you will need to add or modify the following registry entries:

The MaxLargeFileSize registry entry (default value is 51,200 MB (50 GB))
The WarnLargeFileSize registry entry (default value is 48,640 MB (47.5 GB))

The MaxLargeFileSize determines the absolute maximum size that both the .pst and the .ost files can grow to. After this maximum size is reached, Outlook does not permit the size of the file to grow beyond this size.

The WarnLargeFileSize determines the maximum data that both the .pst and the .ost files can have. After this maximum data is reached, neither the .pst nor the .ost files are permitted to add any more data. However, the size of the physical file may still increase because of internal processes.

Important: it is recommended that the values between the MaxLargeFileSize registry entry and the WarnLargeFileSize registry entry be at least 5 percent (%) so that internal processes are not hindered from continuing.

These settings apply to both .ost and .pst files. If you modify these registry values, this can affect .ost files that are used with Cached Exchange Mode, with AutoArchive, and with .pst. files. If Outlook is configured to download shared folders, the contents of shared folders are stored in the local Offline Outlook Data (.ost) file. If the shared folders contain many items or large attachments, the size of the .ost file may grow significantly.

In order to modify registry entries, follow these steps:

Click Start, and then click Run, type Regedit, and then click OK.
Navigate to HKEY_CURRENT_USER\Software\Microsoft\Office\x.0\Outlook\PST (x.0 corresponds to the Outlook version: 16.0 = Outlook 2016, 15.0 = Outlook 2013, 14.0 = Outlook 2010)
Click PST, and then right-click MaxLargeFileSize in the right pane.
Click Modify, and then type the value in the Value data
Click OK.
Right-click WarnLargeFileSize, and repeat steps 4 through 5.

Note: you may have to create the registry values if they do not exist. If the registry values do not exist, follow these steps to create them:

Click Start, click Run, type Regedit, and then click OK.
Navigate to HKEY_CURRENT_USER\Software\Microsoft\Office\x.0\Outlook (x.0 corresponds to the Outlook version: 16.0 = Outlook 2016, 15.0 = Outlook 2013, 14.0 = Outlook 2010)
Right-click Outlook, point to New, and then click Key.
Type PST, and then press ENTER.
Right-click PST, point to New and then click DWORD
Type MaxLargeFileSize, and then press ENTER
In the Edit DWORD Value window, choose Decimal and type the value in the Value data box, and then click OK.
Repeat steps 5 through 7 to create another DWORD WarnLargeFileSize, and then close the registry.

Value for registry entries should be set in either bytes or megabytes and you will need to calculate it first. You can find predefined values for 100 GB and 95 GB below:

MaxLargeFileSize should be 100 GB = 102400 MB

WarnLargeFileSize should be 95 GB = 97280 MB

Notes:

Despite the fact that you will be able to open .pst files that are larger than 50GB after making specified registry changes, it can still significantly decrease the performance of your Outlook application.
We don’t recommend increasing it to more than 100GB due to the nature of our shared environment.

In old Outlook data file types, the entries MaxFileSize and WarnFileSize were in use. Values under MaxFileSize and WarnFileSize have been used for the old-type ANSI format (an earlier Microsoft Outlook format) data files. The ANSI values are set in byte increments. Please note that since Outlook 2003 version the datafiles are in new UNICODE formats as ANSI format supports 2 GB data file maximum.

The MaxFileSize registry entry (default value is 2,075,149,312 bytes (1.933 GB))
The WarnFileSize registry entry (default value is 1,950,368,768 bytes (1.816 GB))

If the old-type ANSI data file is in use please consider importing this .pst in the new profile. The old type data file has „Outlook Data File (97-2002)“ in the format of the file. If the value of the MaxFileSize registry entry ever exceeds the ANSI 2 gigabyte (GB) limit on either the .pst or the .ost files, the value will be ignored to limit the size to 2 GB to prevent corruption.

This registry hack lets you restore the old right-click context menus in Windows 11

Microsoft has made many changes in the move from Windows 10 to Windows 11, and not all of them have proved popular. One of the more controversial changes — at least aesthetically speaking — is the new-look context menu.

The menu that appears when you right-click on files, folders and the desktop has been given a revamp in Windows 11 and not everyone is happy with it. If you prefer things the way they used to be, there’s a registry hack you can use to tame the context menu.

While some people love the new look, others are less than keen on the fact that the menu is now bigger than before without giving access to any new options. Depending on what you right-click on, some options have been reduced to unlabelled icons, and this has caused a good deal of confusion.

If you are one of those who prefers the way the context menu looked in Windows 10, use the following registry tweak to change the style.

Press the Windows key and R to activate the Run dialog
Type regedit and press Enter to launch the Registry Editor
Navigate to HKEY_CURRENT_USER \ Software \ Classes \ CLSID
Click Edit > New > Key and create a new key called {86ca1aa0-34aa-4e8b-a509-50c905bae2a2}
With the new key selected, click Edit > New > Key and create a new key called InprocServer32
Select the newly created key and then double click the Default entry in the right-hand pane
Do not type anything, but press Enter (you should notice that the data column changes from (value not set) to simply being blank
Either restart your computer, or just restart the explorer.exe process

When you right-click, you should now see a context menu that looks more like it did in Windows 10.

How to Disable VBS and Speed Up Windows 11

Virtualization-based security, aka VBS, allows Windows 11 to create a secure memory enclave that’s isolated from unsafe code. Another built-in feature called Hypervisor-Enforced Code Integrity (HVCI) uses the capabilities of VBS to prevent unsigned or questionable drivers and software from getting into memory. Together VBS and HVCI add a layer of protection that limits how much damage malware can do, even if it gets past your antivirus software.

Unfortunately, VBS and HVCI have a significant performance cost, particularly when it comes to gaming. In our tests, we found that games ran as much as 5 percent slower with these settings on as with them off. Others have seen even bigger deltas; our colleagues at PC Gamer saw drops of 25 percent, though they tested with a 10th Gen Intel CPU when Microsoft recommends no less than an 11th processor.

Simply upgrading to Windows 11 will not turn on VBS, unless you already had it enabled in Windows 10, where it has been a non-default option for several years. So, at the moment, this is a problem few people will actually have.

However, if you do a clean install of Windows 11 or buy a brand new laptop or desktop with Windows 11, you may have VBS / HVCI enabled by default. Microsoft recommends that OEMS have it enabled by default but notes that „some devices that are especially sensitive to performance (e.g. gaming PCs) may choose to ship with HVCI disabled.“ And we know of at least one OEM, MSI, who told us that they would ship their systems with VBS disabled.

If you’re using Windows 11 and performance, particularly gaming performance, matters most to you, we’ll show you how to check to see if VBS / HVCI is enabled and how to turn it off. However, if you’re not gaming, you may want to leave the security in place.

How to Check if VBS is Enabled in Windows 11

Before you start thinking about turning off VBS, you need to find out if it’s on in the first place.

1. Open system information. The easiest way to do that is by searching for „system information“ in Windows search and clicking the top result.

2. Scroll down to find the „Virtualization-based security“ row. If it says „running,“ VBS is enabled. But if it says „not enabled,“ then you’re done.

How to Disable VBS / HVCI in Windows 11

1. Search for Core Isolation in Windows search and click the top result.

2. Click Windows Security and Ok if asked what app to use. A submenu opens.

3. Toggle Memory Integrity to off, if it was on. If it is not on, skip ahead to step 6.

4. Reboot your PC as prompted..

5. Check system info again to see if virtualization-based security is listed as „not enabled.“ If so, you are done. If not, go to step 6 where you’ll disable VBS in the registry.
