"Your file can't be sent because your organization has sharing restrictions in place."
Hello,

I have a user who experiences this error when she tries to share any PDF via Acrobat’s email function.
There is nothing abnormal about her permissions in the admin console, and she gets this error on almost every single PDF she tries to send, so it’s not a permissions issue related to the individual file. We ran an Adobe repair and rebooted her PC. Under Security (Enhanced) “Enable Protected Mode at startup” is unchecked.
These are all suggestions online we tried that did not work. Her version of Adobe is the same as the rest of the userbase yet she (and one other person) is experiencing this. 26.002.21901
Any other suggestions on how to resolve? Much appreciated.
