Why did Umar (ra) ban women from praying in the masjid? How do Rasool’s (saw) hadith fit in?

I have read two hadith of Rasool (saw). In one he says not to stop women from offering namaz in masjid (mafhoom). In another hadees, he says that the best namaaz of women is inside the deepest corner of her house (mafhoom). Though he encouraged women to pray at their home he never stopped any lady from praying in Masjid. It was only during Khilafat of Umar (ra) that some incident happened in masjid that he barred women from coming to masjid for namaaz. When the ladies complained to Mother Ayesha (ra) regarding this, Mother Ayesha (ra) replied that had Rasool (saw) seen what you people do in masjid he would have done the same thing. Please explain the two apparently conflicting hadees, the incident that led to the decision of Umar (ra). I am a Hanafi, wanted to know about this for my personal knowledge. I totally support decision of Umar (ra), surely he knew of Rasool (saw) mansha better. Someone told me that this incident is also mentioned in Hayaatus Sahaba.
