Ms solitaire collection error code 121003

Same issues started appearing after recent Win 10 update (1803 I believe) - - very aggravating.

same problems here, also after update W10

I was able to solve my issue by disabling the IPV6 support on my WRT1900AC (V1) router. I did a little more digging and found some discussions about the IPV6 support not being up to par on the older Linksys routers. Things are working much better now.

I get this same error, but only when connected to Wi-Fi. I turn Wi-Fi off and it works.

Coincidentally, the same thing happens with my Office365 account (Microsoft Exchange ActiveSync). My contacts don't update and I have to delete and re-add my Office365 account but it will only connect to the server and add the account if Wi-Fi is off.

Hi Joe,

I solved my problem for 50 % by disabling my Exchange Active Sync account for mail, contacts and calendar and uses only my normal Microsoft account instead .

So you deleted the game and xbox from your smartphone and that fixed what you claim is microsofts problem?  That makes absolutely no sense.  Tou are connecting over 4g lte and when you delete the data associated with that connection everything works fine.  This means the lte connection was corrupting the data and microsofts servers could not synchronize the corrupted data with the clean data on their servers.  If the data was corrupted on their servers, you would not have been able to recover it by simply removing it from your phone.

I had a similar problem with the same issue via an lte connection that appeared to work fine for everything else via lte, but produced an error message with solitaire and xbox.  As soon as I connected via wifi on my smartphone, everything worked fine, indicating my phones data was not corrupted, but the lte connection was corrupting it in transit.  I know a little bit about lte connections as I connected 100 Cisco 2921 routers together over 4g lte connections in a major metropolitan area and surrounding county and i can tell you that simply having "connection" to the network does not guarantee successful transmission of data.  I could send PING packets all day long with no data loss but trying to send actual VOIP traffic over that same connection was not guaranteed.  4g is great, but it still cannot compare to most wired broadband and wifi.

I'm not sure what you do or did for a living if you're retired but at 61/62 years old, your ability to diagnose technical issues is beyond your capabilities.  Please leave that to the younger and trained professionals.
