Only one recipient shows when saving draft by using Exchange ActiveSync version 16.0 in Exchange Server 2019 and 2016

Applies to: Exchange Server 2019Exchange Server 2016


In Microsoft Exchange Server 2019 or Exchange Server 2016, a user composes a new email message by using the BlackBerry Hub app on an android phone. The user separates two or more recipients with a comma and saves the email message as a draft. When this draft is viewed in the Outlook on the web (formerly known as Outlook Web App) or Outlook client, the recipients are displayed as a single recipient and not as two separate recipients. If a semicolon is used instead of a comma, this works fine.


To fix this issue, install one of the following updates:
For Exchange Server 2019, install the Cumulative Update 4 for Exchange Server 2019 or a later cumulative update for Exchange Server 2019.
For Exchange Server 2016, install the Cumulative Update 15 for Exchange Server 2016 or a later cumulative update for Exchange Server 2016.
