In order for proper operation of the Thru Add-In for Outlook, the following software and hardware requirements must be met:
Microsoft mainstream support for Windows 8.1 ended Jan. 9, 2018, and mainstream support for Windows 7 ended Jan. 13, 2015.
Thru will continue to provide best-effort support of the Outlook plugin on these operating systems until the end of 2019.
Microsoft .NET Framework 4.5 or greater

Microsoft Outlook 2013 (both 32-bit and 64-bit versions)

Outlook Cached Exchange Mode should be always enabled.

With Cached mode disabled we may not be able to resolve recipient addresses in some scenarios, sometimes it may work, could be intermittent.
