We’re retiring a batch of employee accounts, and compliance wants a local copy of each primary mailbox before the accounts get disabled. I ran the eDiscovery export first. It split one 14 GB mailbox into two PST files the moment it crossed 10 GB, and now the records team has two files to track instead of one.

What’s actually the most reliable way to export Primary Mailbox to PST file without hitting size errors or losing data along the way?<\/span><\/em><\/p>\n<\/div>\n

Once these employees leave the organisation, it creates a need to create a backup of these conversations and keep them preserved for work-related needs. This is when users turn to Microsoft Outlook\/eDiscovery to backup Primary Mailbox to PST. However, a few of them opt for the <\/span>Aryson Exchange Server Backup Tool<\/b><\/a> due to certain Microsoft 365 size limits and permission requirements. <\/span><\/strong><\/strong><\/em><\/p>\n
