Hello @KatBaylie,
I hope you are doing well, and thanks for reaching out. Sorry for the trouble you had.
Could you please share more details about the issue?
Are you using Acrobat Pro (desktop) or Acrobat Reader/web tools?
Was the previous workflow using Word Mail Merge + “Adobe PDF” (PDFMaker add-in) or a different tool?
Is this happening for all users or just specific machines after the Windows 11 upgrade?
Reasons:
The PDFMaker COM add-in got disabled or unloaded during the upgrade or an Office update.
The Office/Word version was updated to something newer than the installed Acrobat supports, so PDFMaker stopped loading until Acrobat is updated.
Word is running in a mode where the classic COM add-in does not load.
Suggestions:
Re-enable the COM add-in. In Word: File > Options > Add-ins. At the bottom, set "Manage" to COM Add-ins and click Go. Tick "Acrobat PDFMaker Office COM Addin" and click OK. If it is not listed, continue to the next steps.
Check Disabled Items in the same place. Set "Manage" to Disabled Items and click Go. Word sometimes disables an add-in that loads slowly or crashes. If Acrobat PDFMaker is listed, select it and choose Enable, then restart Word.
Update Acrobat to the latest version. Since this started with the Win11 upgrade, the installed Acrobat may predate the current Office/Windows build. In Acrobat: Menu > Help > Check for Updates, install, and restart. This re-establishes PDFMaker compatibility with the updated Office.
If the tab still does not appear, repair Acrobat. Close Office apps, then in Acrobat: Menu > Help > Repair Installation. This re-registers PDFMaker with Word.
Ensure that the Office is updated to the latest available version.
Please note that if it is a complete Enterprise setup, and the apps were deployed by the IT team with any deployment software:
These users need Acrobat Pro or Standard (not the free Reader) for PDFMaker, and Acrobat should be installed and activated on the machine.
If the Win11 image or an Office update rolled out fleet-wide, you may see this across many machines, so it is worth handling the fix (updated Acrobat build plus the COM add-in enabled) in your deployment rather than per user.
If Acrobat PDFMaker Office COM Addin does not appear under either COM Add-ins or Disabled Items, please share:
Acrobat version | Menu > Help > About Adobe Acrobat
Word / Microsoft 365 version and build
Whether Acrobat Pro or Standard desktop is installed
Whether this affects all Windows 11 machines or only upgraded machines

Let us know how it goes, and please reach out with your findings and if you need any assistance.
