iOS8: Mail app Email Address changes in ActiveSync Account information

I have this same problem but we are still using Exchange 2007. Is there a similar fix for it? We have tried changing everything to lowercase except the primary smtp address. The only thing that seems to work for sure is deleting all of values in the proxyaddresses attribute except for the primary smtp address. We are using current IOS and Mobile Iron also.

I'm having this exact same problem too - started a month ago

Using Exchange 2010, sp3, rollup 7

In my case it is reverting from the primary email address firstinitiallastname@domain.org to our SIP address firstname@domain.org

We can manually change it back in the iPhone Exchange account settings but it reverts after a day or two.

It seems it's only happening to people with new iPhone 6's, at least they are the only ones who have come to me complaining of the problem.

Affected users are on 8.1 now, and it is still happening.

I also scoured the net trying to see if it happened to anyone else.

I found this blog post from the IOS6 days: google: david rowe exchange aliases

someone posted a comment from the other day that says it's an ActiveSync bug but I haven't been able to find anything else about that.

I'll post if I find any more info. Good luck.

Thanks for the update! Good to know that a fix is coming.

strange that it's a Microsoft issue, but that it just started in September, months after we added SIP addresses.

Here's the Microsofft KB on this issue: 3012580

fix coming in the next rollups for 2010 and 2013, workaround is to change the email type to lower case - in my case SIP: becomes sip:

will see if this helps.

I tried this edit for two accounts we have (changed secondary smtp to firstnamelastname@domain.com from FirstnameLastname@domain.com). This reverted back after a few days still. The account was re-setup on the iPhone 6 as well. Has anyone else had an issue with this recurring after making the lowercase change?

I'm making the changes under SMTP in the Exchange 2007 objects.

Dave is correct - I changed my SIP: to sip: - the simple change in case was all I needed. I made this change 10 days ago with two accounts, myself and another user experiencing the problem. Our mail accounts have remained unchanged since. I'm getting ready to do the same for all my users.

I made the change in the proxyAddresses attribute for the Active Directory user object

I've noticed this behavior as well, but it doesn't seem to actually cause a problem beyond the user receiving a copy of an email message they send if they reply to all.

The correct email address is listed as the from and reply to address if a message is sent outside of the organization and of course, internal users have no problems with it at all.

Is there really a reason to bother changing it beyond the occasional receipt of your own reply? (not trying to be short or snippy... I'm really wondering if it's something I should be concerned about... I've been out on medical leave for a month and will be going back into the office in a few weeks. Based on what I'm going back to, this isn't exactly going to be at the top of my priority list unless there's a real issue here.)

It's only annoying, especially if the user replies to all a lot. I've got about 100 users and so far only one has come to me complaining. But once he started noticing it he became convinced that it was causing other problems, even though it wasn't. Luckily the fix takes about 10 seconds per user. I assume it's probably happening to more than just this one user but they aren't as annoyed or haven't really noticed yet. A 15 minute fix for all my users is better than all the potential back and forth emails. 🙂

II'll take a look in ADSIEDIT tomorrow on this. In addition to the reply-all issue, the account is changing on the device, which can cause confusion as most people in our organization have a default SMTP of first initial last name and this is in signature, business cards, etc. While we have multiple adresses for people, having their devices send email as another device can be problematic for tracing emails, communication continuity, etc.

I just took another look at the user's that were having the issue. In AD, under ProxyAddresses, the prefix is lowercase for all other address types (sip, eum, etc). The user's default/reply-to address is listed as SMTP and has the correct address listed.

User's phone is still showing the firstnamelastname@domain.com format. Did you have to remove and re-add the account once you made any changes?
