“550 5.1.1 RESOLVER.ADR.ExRecipNotFound” NDR error message when you send email messages by using Outlook in Office 365

PROBLEM


When you send email messages by using Microsoft Outlook in Office 365, you may experience one or both of the following issues:

Symptom 1: You receive non-delivery reports (NDRs)

Email messages or meeting invitations are not delivered successfully. For example, you receive an NDR that resembles the following:Generating server: <server name>.local

IMCEAEX-_O=CONTOSO_ou=first+20administrative+20group_cn=Recipients_cn=<username>@<server name>.local

#550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ##

Symptom 2: The AutoComplete feature in Outlook does not work as expected

When you create a new email message and then type a name in the To line, the user’s name is auto-populated. However, when you double-click the name, you experience one of the following issues:

  • The dialog box information is not displayed correctly.
  • Information is missing from the dialog box.

CAUSE


These issues may occur if one of the following conditions is true:

  • You reply to messages that were migrated from personal folders (.pst) files or were migrated by using a third-party migration tool.
  • The Outlook nickname cache (AutoComplete) contains a bad entry.
  • The OfflineAddressBook is not updated or cannot be downloaded.

SOLUTION


To resolve these issues, follow these steps:

  1. Reset the nickname and the autocomplete caches in Outlook. For more information about how to do this, click the following article number to view the article in the Microsoft Knowledge Base:287623 How to reset the nickname and the automatic completion caches in Outlook
  2. If you reply to a migrated message, type the whole email address of the recipient again. If the Autocomplete feature tries to input the recipient name or address for you, click the “X” to delete the entry, and then manually type the whole email address again.

  3. Make sure that the Offline Address Book is operating correctly. For more information about how to troubleshoot the Offline Address Book, click the following article number to view the article in the Microsoft Knowledge Base:2429946 How to troubleshoot the Outlook Offline Address Book in an Office 365 environment

    Cool website!

    My name’s Eric, and I just found your site – viettechgroup.vn – while surfing the net. You showed up at the top of the search results, so I checked you out. Looks like what you’re doing is pretty cool.

    But if you don’t mind me asking – after someone like me stumbles across viettechgroup.vn, what usually happens?

    Is your site generating leads for your business?

    I’m guessing some, but I also bet you’d like more… studies show that 7 out 10 who land on a site wind up leaving without a trace.

    Not good.

    Here’s a thought – what if there was an easy way for every visitor to “raise their hand” to get a phone call from you INSTANTLY… the second they hit your site and said, “call me now.”

    You can –

    Talk With Web Visitor is a software widget that’s works on your site, ready to capture any visitor’s Name, Email address and Phone Number. It lets you know IMMEDIATELY – so that you can talk to that lead while they’re literally looking over your site.

    CLICK HERE http://www.talkwithwebvisitor.com to try out a Live Demo with Talk With Web Visitor now to see exactly how it works.

    Time is money when it comes to connecting with leads – the difference between contacting someone within 5 minutes versus 30 minutes later can be huge – like 100 times better!

    That’s why we built out our new SMS Text With Lead feature… because once you’ve captured the visitor’s phone number, you can automatically start a text message (SMS) conversation.

    Think about the possibilities – even if you don’t close a deal then and there, you can follow up with text messages for new offers, content links, even just “how you doing?” notes to build a relationship.

    Wouldn’t that be cool?

    You could be converting up to 100X more leads today!

    Hey Guys,

    You won’t believe what I managed to secure for you…

    As most online marketers (myself included) you’re probably paying each month or each year ridiculously high fees for online hosting that’s sub-par, slow and keeps crashing.

    FACT: hosting is one of the biggest expenses for online marketers, and
    expensive fees are the #1 reason why many give up quickly or never even start.

    -> This here puts an end to it!
    -> https://bloggybro.com/recommends/profithost/

    WHAT? Enterprise-level hosting for a one-time fee?

    YES – cloud hosting for life with just one small payment, that still gives you 100% uptime, blazingly fast loading times, SUPERIOR service and the best possible support Internet Marketers wish for…

    just ONE time low fee today:

    -> Get started now (available ONLY during early bird!)
    -> https://bloggybro.com/recommends/profithost/

    There’s not really much I can say about this other than – GET IT! I’m sure you can see the huge value in it.

    It’s the same package huge corporations are offering and charging you hundreds of dollars a year.

    Except this one is better in every way:

    [+] unlimited bandwidth
    [+] 24/7 premium support
    [+] faster loading websites

    Let’s not kid ourselves: you know you’re getting this. It’s what’s called in the industry as a “complete no-brainer”.

    So why not get it now while the early bird is live?

    You’d be virtually stealing it – it’s that affordable!

    In fact, wait till you see the price – you get lifetime hosting for LESS than what you previously used to pay for one month of service!

    My name’s Eric and I just came across your website – viettechgroup.vn – in the search results.

    Here’s what that means to me…

    Your SEO’s working.

    You’re getting eyeballs – mine at least.

    Your content’s pretty good, wouldn’t change a thing.

    BUT…

    Eyeballs don’t pay the bills.

    CUSTOMERS do.

    And studies show that 7 out of 10 visitors to a site like viettechgroup.vn will drop by, take a gander, and then head for the hills without doing anything else.

    It’s like they never were even there.

    You can fix this.

    You can make it super-simple for them to raise their hand, say, “okay, let’s talk” without requiring them to even pull their cell phone from their pocket… thanks to Talk With Web Visitor.

    Talk With Web Visitor is a software widget that sits on your site, ready and waiting to capture any visitor’s Name, Email address and Phone Number. It lets you know immediately – so you can talk to that lead immediately… without delay… BEFORE they head for those hills.

    CLICK HERE http://www.talkwithwebvisitors.com to try out a Live Demo with Talk With Web Visitor now to see exactly how it works.

    Now it’s also true that when reaching out to hot leads, you MUST act fast – the difference between contacting someone within 5 minutes versus 30 minutes later is huge – like 100 times better!

    That’s what makes our new SMS Text With Lead feature so powerful… you’ve got their phone number, so now you can start a text message (SMS) conversation with them… so even if they don’t take you up on your offer right away, you continue to text them new offers, new content, and new reasons to do business with you.

    This could change everything for you and your business.
