Email on Android AOSP

The Android Open Source Project (AOSP) operating system, such as on the Archer 3 and Allegro 3, does not provide Google Mobile Services (GMS) such as Gmail. An alternative IMAP or POP email service would need to be used instead with the built-in Email app, such as from your Internet Service Provider (ISP) like Comcast. Or if you have a Microsoft Office 365 subscription, you could install the Outlook app from APKPure or another source. It is technically possible to use Gmail in AOSP, but you would have to first turn on the setting at the following web page.

Or installing a more secure third-party email app could access Gmail such as the following.

Gmail and/or other online email services can be accessed on our rugged handheld computer products by either setting them up in Microsoft Exchange Server than synchronizing the rugged handheld with the network (such as via Wifi), in Outlook on a desktop PC then synchronizing through Microsoft Windows Mobile Device Center (formerly ActiveSync), or directly in the E-Mail mobile client on the rugged handheld itself. A compatible web browser can also be installed and used to access the email service's web client, but this may not work as well. Some general instructions are provided at the following web page.

Installing our latest OS release to enable SHA-2 support may also help for synchronizing to services such as Microsoft Office 365. Older Allegro and Archer product models do not provide this support.

Gmail security policies have changed to no longer allow direct access to the IMAP 4 (, POP (, or SMTP ( services without additional steps. The most basic additional step to allow Gmail access on the rugged handheld is to setup and use an "App password" through the following web page.

Otherwise, you would need to disable the additional security in Gmail such as 2-Step Verification or just enable "Less Secure Apps" through this web page.

Email on Allegro CX or CE

If your Internet (or cellular) service provides you with a SMTP email account, you can use the Microsoft Inbox program that comes pre-installed on the Field PC. On the Field PC, tap Start > Programs > Communication or Messaging > Inbox to open the program and set up your account.

If you are using an email service that is not associated with your Internet service provider (cellular service) such as Earthlink, Hotmail, or Yahoo!, you need to use another email inbox program instead of Microsoft Inbox to send email from the Field PC.

A program such as the UK Support nPOP allows you to confirm your user name and password when sending email (which is required for non-ISP email addresses), and it is available free-of-charge. A version of nPOP compatible with older Allegro models (running Microsoft Windows CE) is available to download by clicking on the following website:

Once downloaded, extract the ZIP file, connect the Allegro to the desktop PC via Microsoft ActiveSync, and run the extracted program.
