Travel Time for Outlook / OWA

OK folks, we have an updated version of our Travel Time add-in for you.


  • Uses Outlook API (destined for decomissioning in November 2022 but who are we kidding?  It'll go way beyond that!) and Office JavaScript.
  • Will work with OWA or Outlook 2016/2019 on Windows 10 and needs an 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 addin 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).

You will need to side-load with this address:

Migrating to Office 365? Hint: Disable Throttling

Throttling is a wonderful feature to get rid of during a migration.  You have the need -- the need for speed.  Throttling can sometimes be the annoying speed bump or rumble strip that at best slows you down and at worst halts your migration.

Fortunately there's a good guide to how to disable using the user interface on Office 365:  Disable EWS throttling in Office 365 – Exchange Online

We don't re-do work that's already been done -- this is a good, straight-forward guide.

If your interface does not have this option, open "Help" and type in "Increase EWS Throttling Policy."  Should bring up this page and you're good to go.

Migrating from Apple iCalendar to Office 365? Use GUIDs.

If you're migrating from Apple's calendar offering, you need to map the user GUIDs to target email address in Office 365 / Microsoft Exchange. 

Your mapping text file should look like:






How do you GET the GUIDs?

Via an LDAP Query is most convenient.


Go to it!

Travel Time for Outlook / OWA

What can we say?  We're market-driven.

We didn't get much response the first time we did a travel time add-in for Outlook / OWA, but in the last few months our volume on this has improved so we re-wrote the code.

Our thinking is that we'll keep the version we currently have available for free (it's based on version 1.4 of the Outlook JavaScript API) while we work on a more full-featured version for the enterprise..

Want to try it out -- contact us.

Sumatra Calendar Insight prototype available online

Calendar-minded folks,

We've been working on something we call Sumatra Calendar Insight -- and we'd like you to try it out.

Where are we going with this?

Frankly, we’re looking for direction.  Over years of migrating legacy calendar servers into Exchange we’ve often done analysis on the data and approached mining it in several different ways (usually for resource availability and effectiveness).  

Microsoft MyAnalytics does a good, simple job of helping you get focus time every week or so, and Microsoft Productivity Score promises to give your admin some insight on your global productivity on some schedule with a single score, but missing in all of this is on-demand access to the kinds of detailed statistics power managers and enterprise watchdogs need.  And of course, everything Microsoft does has ignored resources – maybe not an issue now but the pandemic will not last forever.  

Sumatra Calendar Insight is a proof of concept demo – we can get at this data and deliver it to you on demand.  

So we’re asking: what kinds of data do you want to get at?  And why?

Let us know.

Looking for test sites for a new calendar app for Office 365


Having been locked in our houses / apartments / cells / space ships for a few months we started working on a new application that analyzes calendar data for users on Office 365.

We think that calendar analysis should be more detailed than asking "do you think you have enough time set aside for doing real work?"

We're thinking more like "Wonder how your team is spending their time?” and “Too much video and not enough work?” and "We've got a Zoom contract, what're these Teams video meetings doing here?"

Of course we can also do this server-side in Exchange and look at group aggregate statistics,which we think is a lot more interesting in a corporate environment.

A few screenshots follow.

Anybody want to try it out in a beta version please let us know -- we like listening to people.
