Synchronizing New Outlook with Google Calendar

Your reply, as well as others, has settled the Windows Mail and Calendar issue for me. I just went over to the dark side and set up Google (Alphabet) calendars to automatically open up in both browsers that I use (Chrome and Edge) and be synced with the Android (also Alphabet?) calendar in my phone. GMAIL is next up and should also be easy too.This took this old man less than 30 minutes. MAIL and Calendar had been OK for me, like an old shoe, but Microsoft did what my son couldn't- drove me to the simple world of Google.

As mentioned by Keith Gardner, the New Outlook problem has not been resolved. This is why I chose to revert to standard Outlook. Although, it is difficult to get bidirectional sync working on it, it does work.

The solution resides in using Google’s iCal secret or public URL to create an Internet Calendar in Outlook, and then from within the native “Local”calendar interface sending an invitation with the origin defined as the Internet Calendar. Outlook then automatically converts the Internet calendar into a local device calendar and bidirectional syncing works.

Since my original post I tried eliminating the Internet Calendar data file just to see if the local device calendar data was now part of the PST file for the mail account. It wasn’t. So, looks line the iCal URL is now necessary for bidirectional syncing with Google.

Lastly, I have an Exchange/Activesync email account from another service provider. It was a nightmare getting it to work in standard Outlook on the latest Win 11 OS. It doesn’t seem to be supported on New Outlook, either.

To get all of my calendars syncing with Outlook took at least 8 hours. This is unacceptable. MS has somehow managed to make migrating from an old PC to a new o ne more difficult and time-consuming than ever before. (And I go a long way back).

The answer given here by Mr Samuel is not correct or applicable. It in fact is an exact quote of what is already on the Microsoft support site, and it clearly states that this method does NOT support bidirectional syncing, which the user has stated he requires, and the article further indicates that if that is what the user requires, they should use a third-party app such as Sync2Cloud, which the OP specifically stated he is already using. Sync2Cloud, however, is not working for New Outlook.

Therefore the response I am referencing here is NOT an acceptable answer to the problem posted.

For most it seems it's been a Microsoft bug that's been fixed a few weeks ago.

The problem has something to do with the Outlook account flagged "This Computer Only". The solution was surprisingly simple.

After trying nearly everything, I think I've found the solution to getting all Google based calendar activities to sync with Outlook, desktop version. I did the following, though some of the steps may not be necessary. For those items that may not be necessary, I've so indicated.

1. Uninstalled both Microsoft mail and New Outlook. (may not be necessary)
2. Created the Google calendars on Outlook.com (may not be necessary)
3. Copied Google secret iCal address and pasted it into Outlook's Internet Calendar.
4. I also had an account with no private/secret iCal address. For this I used the public address and after trying multiple times managed to successfully integrate it into Outlook's Internet Calendar.
5. The only reason that steps 4 and 5 were necessary, was that the calendar must appear at least as "Other Calendar" or under My calendar.
6. I exported the PST files from my old computer, and imported them into Outlook on the new computer. (may not be necessary)
7. I moved the calendars up from Other Calendar to My Calendar
8. Finally, and this was what changed everything, It is the single most important step. I opened the Outlook embedded calendar, the one flagged as "(This Computer Only)" and created a calendar invitation by selecting one of the Google email accounts as the origin. Upon sending the invitation from each Google email account their associated calendars were then automatically flagged by Outlook as "(This Computer Only)". From that point forward ALL of my calendar activities have been correctly sync'ing with Google.
9. Lastly, I tested all of the accounts with each other, and ... voila, problem fixed.

If I chose to, I think that now I could go back and delete the "Internet Calendar" data files in Account Settings, because I believe the calendar data is now part of the corresponding account PST.

If anyone knows why this worked, I'd be curious to find out.

Thanks and best of luck!!
