Outlook address book freezes when sending file from Acrobat Reader DC

[#1]

Outlook address book freezes when sending file from Acrobat Reader DC.

steps to reproduce the problem:

1. Open a pdf file in Acrobat Reader DC (Chinese Traditional 20.013.20066)

2. Click "Send file by email" in Acrobat Reader DC

3. Outlook message window pops up, click "Address Book"

4. Click "Cancel"

5. Click "Address Book" again, now it freezes when I'm trying to type in the search box:

It seems "Adobe Acrobat 64BitMAPIBroker.exe" is causing the problem because

it appeared in windows task manger after I've ended task for reader dc and outlook.

Tested on Windows 10, Outlook 2013 and Outlook 2019
