iOS9 Mail app doesn't work

[Rubisco]

UPDATE: the problem is related to the IMAP account (my workplace). Gmail is working fine and the mail app behaves correctly.

I've just upgraded to iOS9 on my iPhone6. Everything seems to work fine, except the mail app. When I launch it, it pops up and then immediatly shuts down. I rebooted but nothing changed. Are you experencing the same issue?
Thanks

I am having a similar issue. I have several accounts on my iPhone, and one--an imap account--stopped working reliably with the upgrade to iOS 9. Accessing that account results in emails failing to load into that account. It'll spin its wheels for a long time until I give up and kill the Mail app. On re-starting the Mail app, that account shows no mail. It'll rebuild itself after some time but this is very annoying behavior...

I'll try deleting and re-adding the account. That's all I can think to do. Hoping other suggestions might come to this thread.

UPDATE: For now, deleting the account and re-establishing it seems to have worked. We'll see; I'll update this thread further if problems recur.
