Note Outlook data files may be either personal folders (.pst) files or offline folder (.ost) files.
You may also consider using synchronization filters for Cached Mode profiles to reduce your .ost file size. The following blog post describes how to reduce the size of your local data file by using synchronization filters. (This post applies to Outlook 2007 and later versions.)
This is a stopgap solution and is provided here for reference if you cannot reduce the size of your mailbox. For example, you may be unable to reduce the size of your mailbox if you have to maintain an archive of all sent and received email messages over a span of several years.
Outlook 2013 and later versionsFor Outlook 2013 and later versions, you can also try to use the Sync Slider feature for Cached Mode profiles. This feature lets you control how many months of email messages are synchronized with your .ost file. For more information about the Sync Slider feature, click the following article number to view the article in the Microsoft Knowledge Base:
The following list summarizes expected behavior based on the size of your Outlook data file.
- Up to 5 GB: This file size should provide a good user experience on most hardware.
- Between 5 and 10 GB: This file size is typically hardware dependent. Therefore, if you have a fast hard disk and lots of RAM, your experience will be better. However, slower hard disk drives, such as drives that are typically found on portable computers or early-generation solid-state drives (SSDs), experience some application pauses when the drives respond.
- More than 10 GB: When the .ost file reaches this size, short pauses begin to occur on most hardware.
- Very large (25 GB or larger): An .ost file of this size increases the frequency of short pauses, especially while you are downloading new email messages. However, you can use Send/Receive groups to manually sync your mail. For more information about Send/Receive groups, see the "Are you synchronizing many RSS feeds?" section.
