What does "hxa" mean, Microsoft?
No answer... So I went and did some research myself!

HxA means first inbox. Breakdown of the acronym's letters in reverse order:

A simply means "first" (The next one would be HxB, then HxC, and so on...)

Hx means one of these three apps:

• HxTsr.exe - 17M + 33M - 806 - Microsoft Outlook Communications -ServerName:Hx.IPC.Server
• HxOutlook.exe - 46M + 1M - 618 - Microsoft Outlook -ServerName:microsoft.windowslive.mail.AppXfbjsbkx...mca
• HxCalendarAppImm.exe - 27M + 1M - 1863 - Microsoft Outlook Calendar -ServerName:microsoft.windowslive.calendar.AppXg9pag...mca

All three processes above share some of their details, like:
CPU usage: Suspended
Path begins with: C:\Program Files\WindowsApps\microsoft.windowscommunicationsapps...
Company: Microsoft Corporation
And: (No signature was present in the subject)

Edit: In the past HxA was a file extension for Microsoft Help 2 Attribute Definition Files
