I recently switched from a Galaxy Note II to the Nexus 5. Although I like the Nexus 5 a lot, I was unaware before I bought it about some of the issues it has with Microsoft Exchange. I've read a lot of posts/complaints online from various places but it seems the problems are inconsistent (some people have problems, some don't) and no one has a definitive fix. I was having trouble synching Exchange with my Nexus 5, so I have started using AquaMail instead of the stock e-mail app (I actually connect to Exchange via IMAP with AquaMail, which is just fine) -- but I still rely on Exchange synching for calendar and contacts. Unfortunately, I can't get my Nexus 5 to do that unless I manually click "synchronize" in my calendar and contacts apps (which isn't very convenient!). Any suggestions???
