Error: "Your server administrator has limited the number of items you can open simultaneously" When Manually Archiving a Large Amount of Emails in One Batch with the GFI Archiver Archive Assistant

Author: Luis Fernandes Updated

Overview

When trying to manually archive a high amount of emails, e.g., more than 250, at once via the GFI Archiver Archive Assistant, the emails are not archived.

The Archive Assistant's Outlook.Addon.log debug log file displays the below error message:

"error ","Outlook.Addon","ERROR: Caught exception. ;System.Runtime.InteropServices.COMException (0xA0B40305): Your server administrator has limited the number of items you can open simultaneously. Try closing messages you have opened or removing attachments and images from unsent messages you are composing.

This article provides a resolution for the above-mentioned issue.
