Saving new pdf to SharePoint

I have been trying to save a PDF file to my desktop and to my One Drive.  I get "The document could not be saved.  Write error."  I did got to Preferences>Documents> and unclicked Save As optimizes for Fast Web View.  I really don't understand why this is such a problem.  Please advise, because this is not what I signed up for.  I need a program that works without bugs like this that take now an hour of frustration.  Thanks.  Greg Erkins

Hello emily,

They abandoned you here for two days??!!!

I've haven't seen anyone replied to your post yet; hopefully you found a solution.

So, first off, please see the release notes for your version of Acrobat. Adobe published a bulleting addressing security vulnerabilities  21 hours ago for the Classic Track version that you are using

See here: Adobe Security Bulletin

I read a little bit and these are the steps I will share to aid you in some way

Step 1 - Update your Acrobat  version

Step 2 - Please see this link (is a little reduntant to your case but is always good practice to go back to the basics

Access your SharePoint files in Acrobat, Acrobat Reader

And review step by step if you missed something when you were setting up your SP account.

Step 3- Check your browser compatibility first, then  follow some of the  tips here on how to convert files:

Using Adobe Document Cloud for SharePoint and OneDrive

Step 4- Review how did you created your your Share Point site by following these guidelines:

Create a team site in SharePoint - Office Support

How to switch accounts betwen Microsft Account and  Office 365 and compare with Adobe's if it could be a password conflict underlying somewhere.

See here: Where to sign in to Office 365 for business - Office Support

Step 5- This last step I think it is the most significant  since you had to decide which template to use before the SP site was created.

See here :   Create a site - SharePoint

After you identify if you missed something when you created your SP site, like for example, the type of  template that was used, scroll down to paragraph #6 where it says

                     "the Permissions section, select whether you want to provide access to the same users who have                        access to this parent site or to a unique set of users. If you click Use Unique Permissions, you                            can set up permissions later after you finish entering information on the current page."

And dig a little more  about setting up permissions .

Hope this helps and good luck in this journey
