I had the same issue with the Adobe Acrobat DC on a PC of one of our users. Tried several things, until I bumped into the following known issue on site of Adobe: "Send Mail. Problem: Not able to use Outlook's other windows while outlook Draft message window is active (launched through Send File as attachment).[3829341]".
So, I closed a draft message in Outlook and ... bingo ... send via email worked in Acrobat!
Is there a solution on this issue? - we're haivng alot of users with this issue. Have tried multiple things, but nothing a probally working for us. Such as, reinstallation Adobe, checking for missing updates, disable cloud savings and installed 64-bit instead of 32-bit.
All computers are fully updated to 21h1. It worked for a while, when we installed the 64-bit version, but stopped again...
This is very unstable, and we hope that there will be a fix soon.
We ave having this issue at my company as well. Multiple people across multiple departments! Also this same blank bug is happening when the user trires to save as the pdf also!
Can you tell me how you disabled cloud saving? Ive been googling it for an hour and havent found anything useful and cant find the settings that are mentioned.
We apologize for the inconvenience caused to you and we are actively investigating the issue you have started facing with the latest Acrobat update.
Would like some more information from you -
1- Do you see blank view when you click on Home->My Computer or Home->Document Cloud also?
2- Could you please check what is the folder path shown in "CEF_DIR" key at the following registry - (if you have Adobe Reader) HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Adobe\Acrobat Reader\DC\Installer or (if you have Adobe Acrobat) HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Adobe\Adobe Acrobat\DC\Installer?
and if that folder path actually exists on your machine?
To check the above registry, please go to Start->type "regedit" and press <ENTER> key. This will open registry editor.
