This portion describes the comprehensive and straightforward approach for troubleshooting Outlook data files that have exceeded the maximum size limit. A warning message appears on your computer screen when Outlook data files approach their maximum size. Don’t panic. Keep reading and follow the solutions as follows:
Delete all unwanted items.
Deleting unneeded emails and other material aids in shrinking the size of the PST files. It resolves the issue where the Outlook data file has exceeded the maximum size.
- You must first load the PST file. Select the items that will be unimportant to you in the upcoming days.
- Afterwards, you may delete all of the highlighted objects.
- Finally, permanently remove the deleted items folder.
However, data files that are no longer required by the user must be erased from an enormous PST file on a regular basis. This is the most basic approach for freeing up PST file space and preventing files from exceeding the maximum size restrictions. Similar data items in the PST file are also eliminated to free up excess memory. This avoids the problem that the PST file has reached its maximum size.
Increase the size of PST file manually with registry entities
Actually, there is a built-in option provided by Outlook to increase the PST file size. If you don't want to delete any files, then this solution could be the best and most appropriate for you. Read the steps as follows:
- 1. Firstly, execute the run command (press Windows + R).
- 2. In the opened window, type "Regedit" and press the OK icon.
- 3. When the My Computer menu opens, double-click on the "HKEY CURRENT USER" option.
- 4. Next, double-click on the "Software" folder and pick the "Policies" option.

Archive the Outlook data files (PST).
You may archive your Outlook files to keep them secure and save a lot of storage space. As a result, to prevent them from clogging up and exceeding their maximal size limit, you may preserve the old times in a dedicated Outlook data file to save them.
However, it should be known to you that if your account links to an Exchange Server, then the Archive and AutoArchive functions may not be present in Outlook. Read the steps as follows if you don’t know how to archive your Outlook data files.

Oversized PST file should be compressed.
This approach is compatible with Outlook 2013 and later editions. You may regain space left by removing objects by using the "Compact Now" function. This function aids in the compression of large PST files. However, Outlook automatically compacts data files if it has more than 20% free space. You may also manually condense the PST file by following the following steps:
- 1. Firstly, navigate to the File tab in Outlook.
- 2. Select Account Settings from the drop-down menu.
- 3. Choose the Data Files tab and then pick the pst file you wish to compress.
