Sumatra’s Travel Time – An Outlook Add-in


Are you often late for out-of-the-office meetings after someone booked time your calendar when you really should have left the office? In your mad dash to make the meeting you mutter: “if I had an airplane, I still couldn’t make it on time[fusion_builder_container hundred_percent=”yes” overflow=”visible”][fusion_builder_row][fusion_builder_column type=”1_1″ background_position=”left top” background_color=”” border_size=”” border_color=”” border_style=”solid” spacing=”yes” background_image=”” background_repeat=”no-repeat” padding=”” margin_top=”0px” margin_bottom=”0px” class=”” id=”” animation_type=”” animation_speed=”0.3″ animation_direction=”left” hide_on_mobile=”no” center_content=”no” min_height=”none”][1]”. You can do it on your handheld phone, but not in Outlook or Office 365. The wait is over – This Outlook add-in addresses the problem!  Sumatra Development’s Travel Time adds a “travel time” event to your calendar.  Sumatra is developing a “pro” version of the add-in that will use geo-location analysis to figure out the time to get from your current location to your event location, and add a new travel time event to your calendar. But we still wanted to get this free add-in out there to get some feedback.


Please let us know what you think, if you have problems, etc. This BETA version of the Sumatra Travel Time (TT) Add-in runs through 12/15/2021.  No guarantees, but no bills either.


  • Uses Outlook API (destined for decommissioning in November 2022) and Office JavaScript.
  • Will work with OWA or  Outlook 2016/2019 on Windows 10 and needs and Office 365 account.  Need other platforms, please let us know.
  • It’s not (yet) in the Microsoft store so you’ll need to side-load the application.  This link tells you how if you do not know.

Privacy and Permissions

We hate spyware. Sumatra’s Travel Time Outlook add-in does do not collect ANY of your calendar information, passwords, usernames, etc.   Only you know what you’re using this for.  We will rely on you to let us know what you think.

This applications runs only on your machine, and only if you are logged into Office 365. You do not need your administrator to modify your company’s server permissions.  BUT, this add-in requires read-write access to your mailbox (otherwise we can’t create new appointments).

So if you give this away — how do YOU GUYS make money?  Well, we’re not giving everything away — the really cool features of checking your travel time and alerting you are in the version we haven’t released yet — we’re still working out how to monetize that without going through Microsoft’s horrendous rigmarole.
