Maximum file size to send Outlook. Setting the maximum message size to Outlook Web App. Nontament Size Restriction

This file stores all - mail, contacts, tasks, schedule, etc. This approach is very convenient in the sense that such files can be created as much as you like and transfer them enough to simply transfer from one computer to another. But, unfortunately, there is a small restriction on the use of PST files - it should not exceed a certain limit. However, there are ways to prevent the user about exceeding the size and produce archive procedures in a timely manner. Consider.

PST file restrictions depend on its type. The fact is that starting with the version of Microsoft Outlook 2003, on the equal to ANSI format, you can create PST files in Unicode format. Thus, Microsoft Outlook supports two PST file standards. For each of these standards, its size limit is for the old ANSI format - 2GB limit, for the new Unicode - 20 GB. When installing Microsoft Outlook 2003 and especially 2007 all PST files have a new Unicode format.

It runs the opinion that when the size of the PST file is close to the maximum, Outlook begins to work incorrectly - refuses to open mail and so on. In order to prevent such behavior, special keys in the registry, which we now consider it. For these parameters are installed certain values By default, so you should not hurry to change them - for most users it is not required.

So, we have the following parameters:

Let's help those who help!

MaxFilesize.. The MaxFilesize parameter serves to indicate the absolute maximum size For PST and OST files. Upon reaching this size, an increase in the file stops.
WarnFilesize.. WARNFILESIZE parameter serves to indicate maximum number Data in PST and OST files. After reaching this limit, add data to PST and OST files is not possible, but the physical file size may increase due to internal processes.
MaxLargeFilesize.. The same as the MaxFilesize parameter, but for Unicode files.
WarnlargeFileSize. The same as the WarnlargeFilesize parameter, but for Unicode files.

In the table below, the MaxLargeFilesize and WarnlargeFileSize parameters are related to the Unicode files (new format for large files), and the MaxFilesize and WarnFilesize parameters are to files in ANSI format (former Outlook format). The increment of parameter values \u200b\u200bfor unicode files is carried out in megabytes (MB), and for the files in ANSI format - in kilobytes (KB).

These values \u200b\u200bare installed in the Registry on the next way:

Outlook 2007.

Outlook 2003.

HKEY_CURRENT_USER \\ SOFTWARE \\ POLICIES \\ Microsoft \\ Office.0 \\ Outlook \\ PST HKEY_CURRENT_USER \\ Software \\ Microsoft \\ Office.0 \\ Outlook \\ PST

If these parameters do not exist, then you need to create.

Thus, you can receive notifications in a timely manner when the size of the PST file approaches the critical value. If it happened, you can try to compress the PST file, archive the PST file or make a backup of the PST file.
