Outlook.com ActiveSync no longer working, even after recreation My Outlook.com ActiveSync for contacts and calendar simply stopped working a few days ago. The locally added contacts and calendar entries are there, but nothing is synced with MS.

In the hope of fixing the issue, I deleted the activesync account (beware: now lost all contacts and calendar entries on device!!) and recreated it.

The account is correctly set up, and the email part (that I don't use) seems to work, but no contacts or calendar entries are synced down from outlook.com / live.com.

Several delete+add and phone reboots didn't help.
After messing around, I finally noticed that, after creating the fresh ActiveSync account on my android phone, the eas account's EMail showed a kind of "welcome mail" from MS, that read in the subject "ACTION REQUIRED ..." (paraphrased).

I took a closer look at this Email, and it asked me to set up the Outlook App. And if I didn't wish to set up the Outlook App, I should follow a link to continue syncing with the built-in apps. I didn't notice this the first few times, because normally I don't use outlook.com mail and normally I just ignore Welcome Mails.

After I clicked this MS link, the sync started to work again for both contacts and calendar.

Let's just not start a rant on how MS wasted dunno how many hours of my time through this ... sigh
