I encountered a problem while trying to sending an e-mail using the "envelope" icon in Adobe Acrobat Reader. I looked around in other posts in the community and I realized that this is a frequent problem and no one can resolve it.
That's the current situation:
While trying to send the PDF as an attachment using the embedded feature, the message "An error occurred while sending mail" appears.
Can you help me?
I was able to fix this issue by enabling Cached Exchange Mode in Outlook.
Be sure that Outlook is open in the background before you select 'Attach to Email', otherwise you may be prompted to sign into Outlook. If you have Outlook open alreadty and you're prompted to sign in, you should be able to close out of the sign-in box without receiving the error as long as Cached Exchange Mode has been enabled.
Be sure to restart Outlook after enabling Cached Exchange Mode before testing if the fix worked.
Hope this helps.
This worked for me! Cheers
in my case, resolution was to totally uninstall and reinstall Office suite.
Yesterday it worked. Today I tried to to email as an attachment and it didn't.
After some pick-and-shovel work on google I found that "repairing" Microsoft Office fixed it for me.
