Office 365 Outlook email issue

Nita McKinney 76

Please forward steps to remedy the following message I'm getting while using Office 365 / Outlook. Nothing has changed - no settings have changed:

Delivery has failed to these recipients or groups: ****@*******.com Your message wasn't delivered because the recipient's email provider rejected it. Diagnostic information for administrators: Generating server: SN6PR0102MB3373.prod.exchangelabs.com ****@******.com Remote Server returned '550 5.7.520 Access denied, Your organization does not allow external forwarding. Please contact your administrator for further assistance. AS(7555)'

I have a simialr problem since 1-2 days. I get an EMail from external sender and short after it a message that it couldn't be deliverd to xxx@Stuff .com. Something in addtion tried to send it to xxx@Stuff .com (it is NOT my gmail account). What is this? The message I get is

Generating server: AM0PR07MB4962.eurprd07.prod.outlook.com
xxx@Stuff .com
Remote Server returned '550 5.7.520 Access denied, Your organization does not allow external forwarding. Please contact your administrator for further assistance. AS(7555)'

Same problem here, but there's not any forwarding involved. Impacted messages are from Outlook addresses to Outlook addresses. When group emails are sent within my organization (I'm the admin) only one person's email returns this error: '550 5.7.520 Access denied, Your organization does not allow external forwarding. Please contact your administrator for further assistance. AS(7555)'. No settings have changed. All other email addresses within the organization seem to work fine, with messages being delivered.

Suggestions?

LHlovenic, You need to try the steps Andy David outlined in his comments, despite that you feel message exchanges are within your company Outlook domain. This is a typical MS (microsoft or, more accurately, Multiple Sclerosis) issue, cause and effect.

Microsoft's reply to us was that they sent out bulletins. With the volume of bulletins MS releases to us we simply don't have the time to sift through each and every one of their plethora of bulletins for data pertinent to business or our clients and the titles, subject lines don't always remotely define the content of those bulletins related to our needs and requirements,

well, PRC has Microsoft OS [core-codes] for monitoring. that may be why this problem comes to outlook/hotmail services.

I have got the same problem today, for the same individuals and groups of which there was no problem before. This reminds me that the PRC has Microsoft OS [core-codes] for monitoring.

Hello,
I found way how to fix this problem without need of power shell commands.

1) In exchange admin center create new contact that you want to forward to.
2) In mailboxes - select user you want to be forwarded and go to Manage mail flow settings
3) Edit email forwarding and enter your created contact
4) wait few minutes and you can forward

If you don't create contact it wont let you select email address.
To modify global forwarding policy you need powershell command to allow you make modifications to any global rules.

I hope that you find this useful as I seen a lot of ppl to struggle with it.

I used this to work around it:

Installed Powershell 7.1 so I could use latest Exchange EXO V2 module.

Open Powershell 7 prompt (not regular)

Install-Module -Name ExchangeOnlineManagement -Scope CurrentUser

Connected using: Connect-ExchangeOnline -UserPrincipalName <adminemail>

Used "Set-HostedOutboundSpamFilterPolicy -identity "Default" -AutoForwardingMode On"

I've turned Outbound Spam Policy, Automatic Forwarding to "ON".
Still getting the the same rejection...
Does it take some hours for the setting to propagate to the Server?

It took a few hours (to propagate to the server?) but mine is now working. Thanks.

You need to create a new outbound policy to fix the issue. It took affect right away. Thank you for the post.

This only works for organizational emails (or emails where you know the domain, I suppose). But for generic external emails being forwarded to an external email, you have to modify the default rule, which doesn't have the 'applies to' filter and thus applies to all senders including random external ones.

I cannot get it to save no matter what. I always get

Security & Compliance

Sorry! We couldn't update your organization settings for now, but we will retry it in background. Please check back later.

Doesn't matter if I use the default or create a new Outbound spam filter policy.

Yes, this is very major bug from Microsoft. They need to fix this as when people email to the person in the org that has email forwarding turn on (but not working) they get NO bounce message! The message just vanishes. The spam policy area does not work either as you cannot save the changes "Sorry! We couldn't update your organization settings for now, but we will retry it in background. Please check back later."

An absolute joke!

yes, we do. it all started some weeks ago and we still can't find a fix.
One Client wants his emails forwarded.
Once I send him a mail the email arrives in his mailbox and message tracking shows me 5.7.520 Access denied, Your organization does not allow external forwarding. as the mail could not be forwarded to the final destination account. I also get no error message in my mail.
The policy for forwarding emails always worked in the past, seems like something has been changed.
Anyone else with the same problems?
