Re: Unable to configure Mail Account to Exchange

Yes. I am having the same problem. My old exchange account would not work so I removed so I could add it back in. Now when I try to add it in I get "Unable to verify account name or password."

Yes I have the same problem.

Am not receiving any Exchange emails since installing beta of El Capitan.

Messages composed and "sent" sit in an outgoing mail folder - but the recipients say they receive them.

Mail for my Exchange account is received with no problem on all IOS devices (phone, iPad mini, iPad).

Thanks for the heads up on the delete and reinstall the Exchange account issues. I was just about to do this but won't now and will use webmail until Apple fixes the problem.

I configured mine as IMAP and it works.

Exchange email works OK, and on two computers the exchange calendar shows, but on one it only shows until I open Mail, then it disappears forever. The files are there in ~/Library/Calendars but it doesn't show in Calendar app.

Filing a radar.

Beta 1!

Any update on this?  I still cannot set it up.  Is the internal and External server the same as Internal and External URL now?

I can receive Echange emails, but not send sinc eit cannot find the Exchange outgoing mail server. Also, the calendar doesn\t see the Echange account either.

Similar issue here:

I lost a working exchange account during the update from DP1 to DP2 and cannot add it again, neitehr in the internet account settings nor in any app using the 'add account' menu entry.

When I add my name, email address and password the system pretends to check, but even entering wrong information (wrong email address or password) won't return an error.

I also have this account configured on antother Mac (10.10) and two iOS devices (on 8.3 and 9 beta 2) where the account works, however the account configuration is not synced over iCloud.

Same problem on my side

I have 7 POP accounts - all proper working

If I activate one of mine 5 Exchange accounts Mail crashes - but new is a new Window which appears before the crash.

This windows asks me if Mail should proceed OR crash with crashlog to Apple. If I select crash it is like it always was. If I select proceed then Mail does not crash, but also not work. Totally frozen. Always.

As I mentioned it also at Beta 1 - it is a shame of the MAIL department to release always Beta versions were Active Sync and Exchange Integration does not work - so it is always stupid for developers to use the Beta because of missing company email accounts. And not every dev has two mac´s.

Rebuilding Mailbox helped to get mails back. But calendar still missing.

Same here. Exactly the same issue.

Once I get the "Failed to validate" message, I am presented with the manual setup. It fails as well.

Noticed someone on a another thread they can add Exchange account without connecting. I would like to see that!

It's definitely broken...guess I have to wait for DP3.

Mark

DP3 doesn't fix the issue. Still no Exchange support

Same same here not able to add exchange nor 365 accounts

For me the problem is that Mail preferences dont save any settings change!

+1 can't create an exchange account in Mail

Fresh install.

I still cannot do this properly in Beta4

I am able to add my 2013 Exchange account in Sys Pref>Internet Accts all all things are checked (mail, contacts, calendar, notes, reminders)...however calendar does not work properly. 50% of the time it never shows. the other 50% it shows temporarily but then vanishes when i go back into Mail.app to do anything Exchange-related.

Have deleted calendar containers in Library as well as application support .plist and cache. no luck.

I have an office 365 account with exchange and was also experiencing the problem of "Unable to verify account name or password".  It would be worth adding that I also have two factor authentiction enabled for all users on the domain.

None of the solutions on this page worked.

I did manage to get the account set up by using an 'application specific password' which I created from here

https://account.activedirectory.windowsazure.com/AppPasswords.aspx

Everything works as expected  in Mail, Calendar and Outlook 2016.

Hope this helps even a few people get over this hurdle.

<rant>This thread is a perfect example of this Apple Developer Forum's biggest problem: someone reports an issue, followed by a litany of posts that report the same problem, and ending with no actual solution. Folks, once the issue is reported, there is absolutely no marginal benefit to affirming that you, too, have the problem. It just adds to the noise and clutter. If you don't have *new* information or a potential solution, please don't post a "me too".

When enering username - write your email address - examle me@apple.com and add your password

Then exchange mail works again

I may have a workaround.

I too was unable to add my office 365 account back in to internet accounts on El Capitan.

The following did work thoough:

After it fails initially, you are presented with the option to select username and email address separately:

I set my email address to my office 365 primary address as normal ...  eg john@mydomain.com

I set the username to john@jmydomain.onmicrosoft.com

Obviously substitute john and mydomain with your actual username and domain.

I hope this works for someone.

Here is how I solve it, following some instrunctions here:

Enter a very basic information when adding a Exchange account (not even a valid email)

Like this:

It will open the fields so you can fill your server information (which seems to be the cause of the errors, since OSX is not resolving it properly)
