I was using Acrobat DC Pro 2015.

When someone sent me an Acrobat document to sign, it was a simple process to send the signed file back. Those steps were Forward > Address it > Open attachment > Sign > Save (defaulted to where the file is located, which is the Outlook temp folder) > Send. Quick and Easy!!

After upgrading to Adobe Creative Cloud a few weeks ago, Acrobat no longer defaults to the Outlook temp folder. It instead defaults to Recent Folders. This makes the signing process more time consuming.
