I have been an Outlook user for a long time and run a business. It

messages from many years ago. Is this a bug or do I need to set
something to keep it from limiting how long or how many it will save?

Depending on Outlook version, which you don't mention, there may be a limit
of 16,384 or 65,536 messages in the Sent Items folder.
