How can ArchiveOne help with poor Outlook performance due to high item counts in mailbox folders?

ArchiveOne Enterprise, all versions


Most Outlook performance issues are not the result of large mailbox size (defined as a mailbox that is 2 GB or larger), but instead the number of items in the folder or folders that are being accessed on the server. Having many items in a folder adversely affects performance because operations in those folders will take longer. In particular, performance is largely influenced by the number of items in the critical path folders such as Calendar, Contacts, Inbox, and Sent Items. This is a known issue described by Microsoft: Outlook users experience poor performance when they work with a folder that contains many items on a server that is running Exchange Server.

ArchiveOne can help with these performance issues by applying an Archive and Delete policy action to Calendar, Inbox, and Sent Items folders. These items would be indexed and searchable by the end user as this information would be in the archive. The item count of these critical path folders would be reduced as the items in the mailbox would be deleted after archiving.

To do this you can create a policy to search both the Inbox and Sent Items folders for items that were delivered more than 2 years ago (for example) and action those items with "Archive and Delete the original".


You can also archive and delete old calendar appointments, that are not recurring, so that they are searchable as well.

The end user would have access to these items not through the normal seamless Outlook view as the original item would be deleted after archiving. Instead they would go to the Search Archive folder in their mailbox to locate these items.
