Outlook Calendar changes not showing up in Google Calendar

Hello there!

I have Outlook email and Calendar (and I'm not sure what else) through work. I shared my main Outlook Calendar to my personal Google Calendar account by importing the Outlook .ICS URL (found in Outlook.com > Settings > Calendar > Shared Calendars) into GC. All events show up usually, but this past week I haven't seen event changes showing up in GC, even more than 24 hours after the changed event passed. I can't find any way to manually force a sync/update.

What can be done to ensure event changes to my Outlook Calendar show up in my Google Calendar? This is important for me because I have a long-established system of meeting reminders based around my Google Calendar, and whether OC supports that setup or not it would be too much work to redo it all for this 1 calendar.

Thanks in advance,

Grant

    same here, even between MS accounts sync not working. Only desktop Outlook updates all events after F9 presed.

    OWA does not - there is no way to update manually, only way is accept shared calendar again in the e-mail. Not even between two Office 365 org.

    Inside one org all is OK. Server OK, going to escalate this weekend...

    I have a similar issue. Our IT team is bamboozled, so I guess it is Microsoft's problem. It started around the time our work email was migrated to Office 365, so about 2 months ago. The differences for me are that I can see Outlook calendar in my Google calendar app on my Android phone (works perfectly fine), but the Google Calendar web is the one which does not display ANYTHING. And, the link reset doesn't work for me.

    Hi,

    I'm not sure if it's a Microsoft or Google problem. If I use the link/URL of the Outlook Calendar (OC) to download the .ics file (using a browser, or a tool like wget), I get the correct calendar information (meaning: I download the file, add an event in OC, download the file again, and the new event is present in de downloaded file). So if I can download the correct information, why doesn't it show on Google Calendar (GC), because I presume Google also 'just' downloads that file from time to time. So either Microsoft is not serving the file to Google as it serves it to me (a 'regular web agent'), or Google doesn't (re-)requests the file/calendar after it was added to GC. Or, the way of serving/fetching calendars changed unilaterally, breaking the communication/synchronisation.

    Maybe an analysis of the HTTP headers (while requesting the .ics file) could reveal the origin of the issue, but I'm not an expert in that. Also, I guess nobody knows how Google requests those .ics files anyway so it's hard to reproduce the process...

    I reported the issue at Microsoft and Google, but no response yet.

    Hopefully someone can bring more insights?

    Best,

    Peter.

    Thanks for the new information Peter.

    I'll provide that information to some people who know more than me and see how I go.
