Frequently Asked Questions

Why does Acrobat crash specifically when using the Office 365 PDFMaker add-in?

This typically occurs due to compatibility issues between specific versions of the Acrobat PDFMaker add-in and recent Microsoft Office 365 updates, or due to corrupted Adobe preference files.

Will repairing the Acrobat installation delete my custom stamps and signatures?

A standard repair via the 'Help' menu usually keeps your user data intact. However, manually resetting Acrobat preferences to their defaults may remove certain personalized workspace settings.

Is there an alternative way to create PDFs if Acrobat continues to crash?

Yes. You can bypass Acrobat entirely by using the native 'Save As' or 'Export' > 'Create PDF/XPS Document' features directly within Microsoft Word or Outlook.
