Email sign in issues outlook

I had this same issue with spark, I suspected it was an issue enabling two factor for spark, but I figured it out without messing with any of those settings. Took a couple of tries to work, but removing the dashes from apple's app specific password worked. IE: instead of xxxx-xxxx-xxxx-xxxx, use xxxxxxxxxxxxxxxx. I used a blank word document to copy and paste the password to remove the dashes because if you punch it directly into spark it's all blanked out. First time I did it, it didn't take, but new emails came through, tried it again and the second time it worked and seems to be working properly now. Best of luck!!

Thanks! I reinstalled and was able to get Spark to work. I accidentally downloaded the latest Spark app first... what did they do to my fav mail app, they kind of ruined it. Downloaded Spark classic (which I love!!) and all is well.

Me too, but using Spark Mail.
