Adobe Converter from Outlook - conversion error from micrograms to milligrams

This sounds like a font/character handling issue during the Acrobat conversion rather than an actual unit conversion.

I’d try this first:

1. Open Acrobat and go to File → Print.

2. Select Adobe PDF as the printer and click Properties.

3. Under Adobe PDF Settings, make sure “Rely on system fonts only; don’t use document fonts” is unchecked.

4. Apply the setting and restart Outlook.

5. Convert the email again and check whether 300 μg/mL is preserved correctly.

Adobe specifically recommends disabling that setting when PDF conversion is affected by system-font handling, because it allows the document fonts to be used instead.

If you need a quick workaround while testing it, Outlook → Print → Microsoft Print to PDF should also let you create the PDF without going through the Adobe PDF conversion engine.

Hello team, has there been any updates to this case please? Thank you!

Hello @athletic_passion4d90

I hope you are doing well, and thanks for flagging this. That's an unusual one. I appreciate the specific example.

To help narrow this down, could you confirm:

• What version of Acrobat (not just Reader) is installed alongside Outlook? Converting emails to PDF from the Outlook ribbon needs the full Acrobat PDFMaker add-in; Reader alone can't do that conversion.

• Is the µg character typed as the micro sign or the Greek letter mu? They look identical but are different characters, and Acrobat has known quirks in how it handles them differently during PDF creation.

• Does the same substitution happen if you convert that same text a different way, for example, printing the email to the Adobe PDF printer instead of using "Convert to Adobe PDF" in the ribbon?

• Does this happen with every email containing µg, or only this one?

That will help us confirm whether this is a font or encoding issue tied to the conversion process, or something specific to this message.

We're here to help, just need a bit more info.
