Right after Thunderbird Updated on Friday, I could no longer attach a PDF to an email using the "send file as an email attachment" function on Adobe Acrobat XI. A message comes back that says: A specified recipient type is invalid. My IT department says that it is because Adobe Acrobat XI is no longer supported and that when other programs are updated they may no longer work. Is there another answer that will allow me to continue using the attach tool tab in Adobe Acrobat XI?

We have some reports that re-installing 60.5.2 after an auto-update works: Download the installer from https://www.thunderbird.net/ and run it.

There is a known bug: Located a bug which is currently receiving much attention. It describes the issue you seem to be experiencing.

Assuming you are currently running Thunderbird version 60.5.2

If the above info on reinstalling Thunderbird 60.5.2 does not work for you then..... As this is an important thing which you are probably using a lot, I suggest you uninstall the Thunderbird program via Control Panel > Program and Features select Thunderbird and click on 'uninstall'.

Then download a fresh install for previous version and report back on whether this works ok.

Choose the appropriate version eg: Windows OS either win32 or win64. Note win32 will work on both 32bit and 64 bit computers.

then choose prefered language Download the file, run and install.
