Office 365 Calendar to Google Calendar (2020) – Microsoft Flow

So, it appears that Microsoft pulled all the Microsoft Flow templates that used to work flawlessly and give you two way sync between Office 365 and Google Calendar.

This might not sound like a massive issue. That is unless you use Google Assistant or Alexa to deal with your day to day Calendar stuff. “Hey Google, remind me where my next meeting is” is rather crap with no information.

So, as a stopgap while Microsoft get their act together and publish some working templates, here is the answer….

Firstly, start with this template on the Flow website. Edit your calendar entries for the Office 365 and Google Calendars you want to sync up. But then you will get an error…..

Flow save failed with code ‘OpenApiOperationParameterValidationFailed’ and message ‘Input parameter ‘newEvent’ validation failed in workflow operation ‘Create_an_event’: The parameter with value ‘”@triggerOutputs()?[‘body/Start’]”‘ in path ‘newEvent/start’ with type/format ‘String/date-no-tz’ is not convertible to type/format ‘String/date-time’.’.

Which is a pretty sucky message to get…. and it took me ages to figure out how to fix it. Until I found a kind forum post hidden away on a site somewhere (which I cannot since relocate). But essentially the answer to fix the above is to remove some items in this section:

You remove the body/Start and body/End entries then add replacements for those, looking at the image below should assist…..

You add two expressions:

 convertToUtc(triggerOutputs()?['body/start'], 'GMT Standard Time') 
 convertToUtc(triggerOutputs()?['body/End'], 'GMT Standard Time') 

You can then remove the bottom part of the description to get rid of a load of rubbish metadata that is pulled over otherwise.

That worked for me anyway! 🙂

    When I enter the expressions here I get an invalid expression error. Do you have any solutions?

      When you copy from the web, the single quote is actually a different character (angled single quote). Replace these characters with the regular single quotes.

        Thanks for pointing that out. I have put in preformatted mode now, does that work?

    This great, this made me get runnign again !
    have been strugling with this a few time without success !

    Now the next thing is:
    I have made a flow that would be able to also update and delete posts from outlook to google.

    But, as the “make event” lacks the “Event ID” is not required, it gets stuck when we try to do a update !

    Any solution for that ?

    Hello. Many thanks. Been looking everywhere for a solution for this! One thing driving me nuts though is that when the events sync from Outlook to Google they are always out by an hour (e.g. I set an appointment for 3pm in Outlook, shows up as 2pm in Google). I think this is something to do with British Summer Time perhaps? Have tried lots of variations on the expressions to get it to work but no joy. Any solutions appreciated. Thanks.

        Did you work out what to change it to? I tried “convertToUtc(triggerOutputs()?[‘body/start’], ‘AUS Eastern Standard Time’)” which didn’t seem to work?

    Thank you, it is working now.
    Nick, Ahmed and Eric, I had the same problem.
    Did some search on the internet.
    I changed ‘GMT Standard TIme” to ‘Central Europe Standard TIme’ but same problem because of the summertime ?
    I changed it to “Azores Standard Time”And now it seems to be ok.

    Thank you, it is working now.
    Nick, Ahmed and Eric, I had the same problem.
    Did some search on the internet.
    I changed ‘GMT Standard TIme” to ‘Central Europe Standard TIme’ but same problem because of the summertime ?
    I changed it to “Azores Standard Time”And now it seems to be ok.
    Not the most beautiful solution, but it works for me 🙂

    I have tried convertToUtc(triggerOutputs()?[‘body/start’], ‘Eastern Standard Time’) and convertToUtc(triggerOutputs()?[‘body/start’], ‘ US Eastern Standard Time’), but each time it’s still syncs over 4 hours later on google. Am I doing something wrong with the time zone?

    I am trying this and running into an issue. I’ve tried all above and also tried using this, convertToUtc(triggerOutputs()?[‘body/start’], ‘Eastern Standard Time’)

    The problem is all of the meetings are coming in 4 hours later on the Google calendar. Any suggestions?

    Here is the solution:

    concat(triggerOutputs()?[‘body/Start’], ‘Z’)
    concat(triggerOutputs()?[‘body/End’], ‘Z’)

    Use these expressions, instead of convertToUtc will solve the issue of time difference. The downside of using “Azores Standard Time” is that when Daylight saving time ends in November, the created events on Google Calendar will be 1 hour ahead of that of Outlook.
