outlook setup error 0x800706ba

This happened for me because outlook only had IMAP accounts, and the contacts/calendars/tasks were the "Contacts (This PC only)" style of folders.

Apple needs to fix their wizard to use those folders as the source of outlook data to load into it's merge and sync logic. Or even better instead of assuming which contacts/calendars/tasks folder and strewing things up have an advanced button that will prompt user to select what folder(s) to use from outlook.

To work around is problem:

Create new empty .pst file

Set it as default data file (File | Account Settings | Data Files Tab | Set as default on new local .pst file)

Close and reopen outlook to make sure it's default data file/moves everything

Re-run iCloud Control panel outlook setup wizard.

The problem is that the configuration between iCloud for Windows and Outlook does not work when your emailaccount(s) is (are all) using IMAP. An IMAP emailaccount results in .ost files on your harddisk.

The solution is that you create a POP3 emailaccount in Outlook 2019, which automaticly generates a .pst file.

It seems that you have a Gmail account using IMAP. In your case: set up a POP3-emailaccount in Outlook 2019 using your existing Gmailaddress and password and give it a different name for reference. This emailaccount can be used as the "new empty .pst file" as referred to by silversword411.

Note: forget about the fact that you now have two accounts in Outlook 2019 using your Gmailaddress. When you followed all steps your default emailaccount is again the one as it was before the workaround. If so, you can delete the POP3-version.

Hello houston611.

Welcome to Apple Support Communities. I understand that you’re trying to add iCloud Contacts and iCloud calendar events to Outlook. You keep getting an unexpected error although you’ve done this successfully in the past. I’m happy to help.

Please try the steps in the section “Calendar, Contacts, and Reminders” here: Get help using Outlook with iCloud for Windows - Apple Support

Do you have any security software installed, such as antivirus software? Do you have any pending software updates for your computer or iCloud for Windows? If so, please install the updates and restart your computer.

Let me know the results.

Take care.

You first have to generate an App Authentication Password in Apple ID to set up an iCloud email in Outlook 365. Second step is to change the default email / data settings to your iCloud address under acccount settings. Once this is done close Outlook and open the iCloud App to sync. This worked for me!

I am having the same problem. Yesterday, I spent over an hour with Microsoft support. We uninstalled Office and iCloud for Windows and then reinstalled them. It works great now except I seem to have iCloud for Windows version 10 rather than the latest version 11.2. It works great for contacts and calendar but not iCloud Photo. Just talked with Apple support. For the first time in some 15 yrs, I got the run around with answers like Microsoft and Apple are working hard and that the latest version of iCloud for windows may have some compatibility issues. He couldn't tell me how to determine which version of iCloud I had on my computer. II asked to talk with a tech that specializes in iCloud and he said they don't have any. Bottom line, don't use the version 11. Uninstall it and reinstall an older version.

Welcome back houston611.

I recommend contacting Microsoft about version 10 of iCloud for Windows here: Contact Us – Microsoft Support

Let me know if you have further questions.

Take care.

Could it be that on your laptop you only have IMAP emailaccounts (the cause of the issue) and on the other 3 you have one or more POP3-accounts?

I have used Outlook 2010 synced to my icloud calendar and contacts for several years. First icloud disappeared from my pc and when I reinstalled, it would not load the contacts or calendar to Outlook. I run the setup and at the very end get the unexpected error 0x800706ba. I have tried to uninstall icloud and reinstall, but the same error occurs.

dear silversword411

I have the same problem under Outlook 2016. As zeltum points out it helped for him so I tend to try the same. My only concern is that I don't know what the consequence of that step is for the function of Outlook? Do you know?

Best regards

Bernd

This is what I do for a living, and that is a big question with lots of answers depending on your situation because outlook and icloud integration is a big pain, and people have multiple accounts, and contacts split between accounts, don't even know where their data is etc. To do it right and make sure you don't loose data it's at least 30mins of work (probably more like 60-90mins) looking at your situation/devices, and making different backups in case iCloud screws you up. It's not something I can give a generic answer for. I offered the above to try and help others understand and give a simplistic workaround for a single simple use-case WHY you were getting a 0x800706ba error and Apple was no help, and none of the search results actually told you the real problem.

If you need personal help you can chat/send me a message on my site (bottom right) is about all I can offer to help ( davidthegeek (dot) com and go to the knowledge base for chat/ticketing). This is a paid service.

There's several articles in my knowledge base talking about ios and what you need to know that is free to try and help you understand ios better if you want to try and tackle it yourself - be warned it's complicated when you're not all-apple services and devices.

OK I have tried several things and have come to this.

I have Outlook 2019 the data files are .ost files. Changing does nothing to help this problem.

The Gmail files are OST files also and they work.

What is the difference a PST file and a OST file that these files don't work?

Highly recomend this solution as it worked for me. Windows 10 home with Outlook 2013. I had seen solutions around deleting the default .pst file / iCloud.pst file; this solution works great as it allows me to keep my original .pst file intact in case of future issues.

Thanks silversword411, saved me hours of frustration.

Travis, Died33 provided a link with instructions on how to do that.

My post was my pro-bono IT work giving back to the community. I figured out the problem when I was fixing it for one of my clients, and didn't see a posted reasons/explanations in any google searches that actually told you what the cryptic 0x800706ba error was about in relation to setting up iCloud Control panel and outlook.

Helping people one-on-one is how I pay the my mortgage. If you need assistance with implementing this, or any other IT help open a support ticket and I'll contact you directly with my paid support options :)

Wasted hours with microsoft and apple support on this and they continually blame each other with each one saying speak to the other.

Your workaround fix it for me. Thanks!!
