17.3 Mail password issue on Exchange account

Well, then you didn’t read carefully. FIRST: This is not an iOS problem, it is a Microsoft problem. Microsoft changed how authentication works several days before the iOS release. So the answer (which is in this thread multiple times) is to visit Microsoft Support for how to address this issue with Microsoft services.

I went to Microsoft Support about this issue. They told me that support for Outlook 2013 expired last April, and suggested that I update to the free New Outlook to fix the problem. I did. The issues seems to have disappeared. However, I still have outlook vs. EAS identified as my mail default on my iPhone. As all seems to be working fine, I don't plan to change that.

My exchange email (company account) was not working after 17.3.1 update. It is now working, but I had to delete the account in Settings > Mail and then re-add. NOTE: I had to do this TWICE for things to work. After the first time, I could get incoming mail, but COULD NOT SEND OUTGOING MAIL. Weird.

Lawrence, that’s presumptive and not correct. I entered everything correctly the first time I removed, restarted, and then added back my account. I know it was correct because I could receive incoming messages, but I could not send outgoing messages. Removing again the account, restarting the phone, then adding back the account (for a second time) resulted in correct functionality, both receiving and sending messages okay.

When you removed the account, did you restart your phone before you added it back? If you didn’t it picked up the previous incorrect metadata that didn’t work.

In general, any time you delete something restart your phone before you add it back.

Try deleting the Exchange account from your phone and adding it back.

I have the same annoying problem (both iPad & iPhone) and I don't have a IT department to help me with this!

I’m having the same exact problem, I’m on 17.1.2. Could it be a virus on the device, looking to capture your password? What happens if you enter your correct password?

The link you provided is for enterprise MS accounts. Regardless an app specific password even for personal accounts doesn't fix this particular issue at this particular time.

I am having the same issue and the Microsoft app password is also not working.

And works????

I have the same Exchange password issue
