Common Problems When Exporting Office 365 Emails
#1. Export option is missing or greyed out
The available export options depend on the Outlook version, account type, permissions, and Microsoft 365 configuration. If you are using Outlook on the web, you may not see a complete mailbox export option. Try the desktop Outlook workflow instead.
#2. Older emails are missing from the PST
This is commonly related to Outlook’s synchronization settings. Microsoft states that Cached Exchange mode can restrict the export to the items currently stored in local cache. Change the setting to download all email and allow synchronisation to finish before exporting.
#3. Sign-in problem
Microsoft 365 account may require modern authentication or additional verification. If Outlook cannot authenticate the account, complete the organization’s sign-in and MFA requirements before starting the export.
#4. The mailbox is very large
Large exports can take considerable time and require sufficient disk space. For eDiscovery exports, Microsoft recommends dividing very large searches into smaller batches when necessary.
