Outlook isn't using my selected timezone in Scheduling Assistant

In the interests of resurrecting old threads did you manage to fix this Emma?

I have been prodding at either the same (or similar) issue within OWA - the fix i found worked was in OWA go to Settings > General then to the Language and Time settings. Change the time zone (even if correct) and at that point a box showed advising the Meeting Hours timezone is set to US Pacific and asking if i want to change it - the 'Yes, please' button then corrected the meeting hours timezone and Scheduling Assistant was happy once again.

God knows why there is a separate semi-hidden option for this :(

Hey John, thanks for the resurrect!

Something, at some point, resolved this, and I have no idea what. I'd made my peace with living with a funky calendar and having to inform my team on a regular basis that the Scheduling Assistant was incorrect.

I don't have the hidden option appear that you're talking about, though I think I remember seeing it way back when I was first trying to resolve this and believe it's linked to the time zone Outlook inherits from Microsoft 365 or something silly like that.

For anyone with this issue, here's the only things I've tried in the past few months that may have resolved this:

• I changed the Outlook Settings > General > 'Use my Microsoft 365 settings' toggle from 'off' to 'on'. I don't believe this toggle was present when I last tried to fix this issue, and it shouldn't have changed anything time zone related as my time zone in both Outlook and Microsoft 365 was identical.
• 'Changed' my time zone in Outlook by setting a new, identical time zone, then deleting it. Did the same by changing my original time zone to something else, saving, then changing it back.
• Did the same in Microsoft 365 - changed the time zone to something else, saved, then back again.

I'm not convinced any of these resolved the issue - it absolutely could have been a behind the scenes bug fix as a result of an update on Microsoft's end.

I'm just glad it's over and I have one less ridiculous Outlook thing to contend with 🙃

Hi emmakpark, I had the same issue on my mac and the only place where I found to update from PDT to EDT was in the web-based outlook app's calendar settings (not the local native app). My timezone was set correctly in all of my native Microsoft apps (teams, outlook, etc.), in my Microsoft 365 acct. on the web, and in my system settings on my mac. I just happened to check the outlook app settings online and clicked into the calendar settings and there was a prompt asking if I wanted to update my timezone from PDT to EDT. I have no clue why that prompt was only there out of the numerous places it would make sense to put it. I hope that helps someone!

In outlook calendar setting, in "Time Zone", Select "Display my calendar in time zone", what you want.

Hi emmakpark

Good day! Thank you for posting to Microsoft Community. We are happy to assist you.

To support further, could I confirm if you Outlook Web you used was link as outlook.live.com or outlook.office.com? Also for your Office 365, it is Office 365 business version or home/personal version? Thanks so much.

Here are a few things you can try to get Outlook Scheduling Assistant to use your selected timezone:

• Check your Windows Timezone settings - Outlook uses the timezone set in Windows. Make sure this matches your preferred timezone.
• Go to Outlook Settings > General > Time Zone and check that the correct timezone is selected here as well.
• Close and reopen Outlook to refresh the timezone.
• Try scheduling a meeting from the invite window rather than the Scheduling Assistant add-in.
• Disable any third-party scheduling plugins/add-ins that could interfere.
• Reset Outlook to default settings which may clear any cached timezone issues:

Go to File > Options > General > Reset

-Select "Reset only my Outlook view"

If not work, Please feel free to let me know how it goes or if I've got you wrong so I can provide further suggestion. You can help to share screenshot via private message I sent as below:
