5.02 caused Microsoft exchange email to stop syncing
On my work email on my Z1... Says it's a certificate issue... So I reinstalled the email account and now it won't even connect to the server... Checked wit it...Not a server issue
Did you try clearing the data for the app before re-signing in? If not, could you please try this. You just go into your Settings > Apps > All > tap on Email (or whichever app you are using) > tap Clear data.
I installed the Mail Wise app and uninstalled the default exchange app. Everything works, email accounts an calender sync! Have used it for two weeks w/obany problems,,,,,
