Have researched this issue and tried many things to no avail. We have several executives in the company using this feature, and it would be nice to get it resolved.
Environment:
Server2012R2 ver 6.3.9600 in RDS mode (current on all updates)
Microsoft Outlook 2016 (16.0.5257.1000) MSO (16.0.5366.1000) 32bit (current on all updates)
Adobe Acrobat Reader Continuous Release | Version 2022.003.20263 (current on all updates)
Fixes attempted:
From Microsoft side:
Delete registry key for HKLM\Software\Clients\Mail|Microsoft Outlook
run Office 2016 repair
verify default email client is Outlook
From Adobe Discussions:
download and apply registry fix - FeautreState 4163520 set to 0
Delete / recreate users Outlook profile
In Acrobat Reader preferences, set Outlook as Default Email client

Uninstall Adobe Acrobat (from AcroRdrDC2200120085_en_US.exe installer) and run Adobe Acrobat cleaner and reinstall (from AcroRdrDC2200320263_en_US.exe installer)
pre-existing AV exclusion for AcroRd32
Add additional exclusion for folder containing 32BitMAPIBroker.exe (C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader\plug_ins\pi_brokers)
Initially Outlook/Office had no updates installed. Installed all available office updates.
Any other suggestions?
