Solution 1Recommended

Sign Out and Re-Sign Into Acrobat Reader and Outlook

Refreshing your account sessions can resolve temporary syncing glitches between the PDF app and the email client.

Authentication or syncing errors between your PDF reader and Microsoft Outlook can sometimes cause interface elements, like the send button, to disappear. Logging out and back in forces the applications to re-establish a fresh connection.

Sign out of Acrobat

Open the Acrobat Reader app on your iPad, tap your profile icon at the top right, and select the option to sign out of your account.

Sign out of Outlook

Open the Microsoft Outlook app, navigate to Settings, select your configured email account, and tap 'Delete Account' or sign out.

Restart the device

Power off your iPad and turn it back on to clear any temporary background cache.

Sign back in

Launch both apps and log back in with your credentials to refresh the app connection, then try sharing the PDF again.
