Microsoft Outlook

Pentagon Mail is a plug-in to Microsoft Outlook and works with versions 2010 and upwards including Office 365. So users will need Outlook on their machines regardless of the back-end email server which could be anything.

Server requirements

There is no server component as the software runs entirely on the user's local machine.

Local machine

You will need approximately 105Mb storage to install the software plus space for the index. The latter will vary depending on the content of your emails but a rough guide is 50Mb for 10,000 messages. As each person would normally only index the messages relevant to their work, the number that they index will often be below this figure.

Installers

The installers and their change logs can be found in the Downloads & Change Log section


NOTE: The 32-bit installer works with 32-bit Windows and 32-bit Outlook

The 64-bit installer is for 64-bit Windows and both 32-bit and 64-bit Outlook
NOTE: If you are running 64-bit Windows we recommend that that you install 64-bit Outlook and NOT 32-bit Outlook



Microsoft Office App

WARNING: Excitech Mail does not work with Microsoft's Office "App". This software is typically shipped with new machines and will need to be removed and replaced with the full Microsoft 365 product.
