This article describes why emails may not reach their destination or appear in sanitization log files.
The email (eml) size may increase as a result of the sanitization process. The size of the email message may then exceed the size limit set in Exchange Server.
To avoid blocked emails in Exchange servers due to message size limitations, follow this TechNet guide:
Organizational limits apply to Exchange 2016 servers, Exchange 2013 Mailbox servers, and Exchange 2010 Hub Transport servers that exist in your organization. Organizational limits that you configure on Edge Transport servers are applied to the local server.
By default the "Maximum size of a message received" is set to 10MB.
If Exchange is your responsibility change this parameter according to your organization policy. If Exchange is part of the VotiroVotiro Cloudcloud solution, contact Votiro Support.
