Resolving 'Out of Memory' Errors in MS Outlook 2007

Having a large Outlook PST file is never recommended. Not only does it increase the chances of PST corruption, it can also make Outlook slow while performing operations like, sending e-mail, receiving e-mail, or even while opening an e-mail. In Outlook 2007, this slow behavior is most likely to occur when the file is 4 GB or larger in size. Owing to this, Outlook starts behaving abruptly and sometimes, throws error messages. One of the most commonly adopted solutions in this respect is to Split PST File. Certainly other options are also available, including deleting unnecessary messages and compacting PST file.

The slow behavior in MS Outlook 2007 can also be attributed to some computer-related concerns. Many Outlook 2007 users often report that they receive the below or similar kind of error message when working with the application or while opening it:

The 'task_name' refers to the name of task that Outlook is unable to complete.
