Email Manager offers several advantages over the standard SharePoint / Teams preview:
Email Manager typically shows an email in 1 s whereas it may take several seconds using the standard viewer.
- View attachments
Email Manager allows users to view email attachments (Office, pdf, jpg, ...) directly in the browser.
This improves user productivity and reduce security/compliance risk by keeping content in the cloud.
- Support for emails with msg attachments
Email Manager support viewing of msg attachments (and their attachments) directly in the browser.
- Extract email metadata during uploading
This requires a one-off configuration and is fully transparent for end-users.
- Tagging emails
Emails of interest can be tagged for future processing (move to other location, add metadata, ...) during viewing.
- Date/time in local time zone
Email Manager shows sent and received dates in the local time zone (unlike the standard preview which uses UTC).
- Quick navigation
Optimised for handling large number of emails by offering previous/next buttons and the option to jump to a specific email.
- Preview emails that are not rendered by the standard SharePoint viewer.
- Attach SharePoint / Teams document(s) to a new email.
Email Manager's speed to display has the drawback that it does not always render emails with fancy formatting (e.g. with colored texts, tables, fancy B2C emails, ...) in their original lay-out.
