Why does iTunes 12.1 does not sync new calendar appointments with Outlook 2013?

I have the same issue. Spent about 5 hours with it on Friday....2 hours with apple support. Still not resolved! Major issue!!! Out the door to travel Monday afternoon.

I Have the same problem, I tried to installed older versions of ITunes but didn't succeed.V12.01.26 installed 12.1

Do you manage your contacts with Outlook as well? Then have iTunes import them to your phone?

I posted a problem about that and it appears that there's an issue with iTunes not detecting Outlook at all. My Outlook has several e-mail accounts and they would be listed in iTunes regardless of I sync'd or not. Right now, it's blank. So is my contact list in my iPhone.

I sync notes, contacts and calendar. Just got off the phone again with support. She had me look for the iTunes addin within outlook. Could not find it. She told me that was why I'm unable to sync. She said when I installed itunes, it should have included the addin. Sounds like this is an Apple/Microsoft communication issue.

Anyone know where I can find the addin I need?

I have the same issue as well. I've been holding off on upgrading 12.1 for some time. Finally did it, and now any new appointments will not sync. I have forced the sync, removed iTunes, reinstalled, no luck. The only difference is I'm using Outlook 2010.

All of my sync'ing was being done via the standard sync cable (no Bluetooth, not against a corporate Exchange server).

As I think back to the days of my Palm Pilot, I don't recall this many issues w/ a simple sync operation. One would think, at this point Apple would have this process fairly well ironed out.

I called Apple about this issue of iTunes v12 unable to detect Outlook and it is a problem that they're aware of. Because iTunes can't detect Outlook, nothing is going to sync.

Thanks Xet. I can see that. I went as far as creating a fresh PST, and moving all of my contacts, calendar, etc on over to that. And sure enough, the sync is exactly the same as it was. It's almost like it 'buffered' a copy of the appointments/contacts and have them in limbo.

The last file in my download folder is iTunes Version 11.2. I installed it but when I connected my iPhone, it said I needed 11.4 or newer to work with the latest phone update.

Is it possible to get this file. I asked the support folks early in this process if I could use an older version and they told me know. It obviously works if you have done it.

I did notice when I installed the older version, the itunes Outlook Addin showed up in the outlook add-ins. Then when I updated again to the latest itunes version...it disappeared.

Thanks for your help. I had done the search and 11.2 was the latest version. The site didn't have the version either. I will be having an interesting discussion in the morning with the support folks. I'm sure someone there can get their hands on the version needed.

Thanks again for your help!

I have the same issue with iTunes 12.1. This has happened to me before so now I always download and save a copy of the iTunes installer. When a new version comes out, I save a copy of its installer. If everything works ok, I delete the previous installer version. If not, I can always go back to the previous version which is what I had to do after installing v12.1.

For me, iTunes 12.1.0.71 wouldn't sync on machines running the 64-bit version of Outlook 2010, but did sync for machines running the 32-bit version. Both machines are running Windows 8.1 64-bit. I noticed that "iTunes.exe" installed in the "C:\Program Files\iTunes" folder, instead of the "C:\Program Files (x86)\iTunes" which the previous version did (12.0.1.26). Problem was corrected when I reverted back to a previous version of iTunes.

Thank you for the update ocwl. I found a couple of 12.0.1.26 w/ a basic web search. By uninstalling the 12.1 as well as the other apple components in my 'add remove programs', I reinstalled the 12.0, and things are working fine. I did check my Outlook 64-bit, and sure enough the add-in is back. And just as you stated, it installed in the (x86) directory again.

I'm back up and running. Thank you.

Same issue here but I can't go back to old version since ax64 DLL got updated to the new version.

I'm on the phone with support let see
