Problem
When you send an email, the email is not delivered, and you receive a non-delivery report with an error message similar to this:
550 5.4.1 Recipient address rejected: Access denied. AS(201806281) [CWLGBR01FT019.eop-gbr01.prod.protection.outlook.com]
Reason
The email was blocked by Directory-Based Edge Blocking (DBEB) in Microsoft 365.
DBEB is enabled by default for your domains in Microsoft 365. DBEB will block external emails sent to email addresses that do not exist within your Azure Active Directory.
Microsoft 365 does not currently synchronise mail-enabled public folder mailboxes with Azure AD. When emails have been processed by Signature Injection Service and are routed back to Microsoft 365, they are considered external by DBEB.
Note
This problem only applies to emails that are forwarded to the Signature Injection Service for signature injection based on your mobile device rules in Email Signature Manager.
Solution
See below depending on your environment:
- If your public folders are hosted in Exchange Online
- If your public folders are hosted in Exchange Server on-premise
If your public folders are hosted in Exchange Online
Directory-Based Edge Blocking (DBEB) does not currently support mail-enabled public folders in Exchange Online.
There are two workarounds:
- Stop routing emails sent to public folders via the Signature Injection Service (Recommended)
- Disable Directory-Based Edge Blocking (Not recommended)
Stop routing emails sent to public folders via the Signature Injection Service (Recommended)
Note this workaround means signatures will not be applied to email sent from mobile devices to public folders.
- Log on to Exchange admin center
- Navigate to Mail flow > Rules
- Select the rule Send to Symprex Signature Injection Service and click Edit
- In the Except if… section, click add exception
- Select The recipient… and is this person
- In the Select Members dialog, select all mail enabled public folders and click Add
- Click OK, then click Save
Disable Directory-Based Edge Blocking (Not recommended)
- Log on to Exchange admin center
- Navigate to Mail flow > Accepted domains
- Select the domain of the public folder
- Change the domain type to Internal relay
- Click Save
If your public folders are hosted in Exchange Server on-premise
Completing the steps below will ensure that mail-enabled public folders will no longer be considered invalid addresses by DBEB:
- Open Microsoft Azure Active Directory Connect
- On the Optional Features pane, tick the Exchange Mail Public Folders option
- Complete the wizard
I am trying to publish my project from my development machine to the staging environment. I would right click the project in visual studio and click publish. Most of the files would publish just fine, but a few were giving me problems. In the output log, there were multiple error messages, all stating:
Unable to add ‘XXX.ext’ to the Web site. Unable to add file ‘XXX.ext’. Access is denied (550)
I’m following this : But I don’t find the «Read-only» attribute checkbox…
So have you any ideas ? Thanks in advance.

I just solved this problem on my own system. It was a permissions issue. What I had to do was grant «write» rights to myself on the IIS directory (in my case wwwroot). I retried the publish from Visual Studio and it worked perfectly.

Open visual studio in administrator mode. It solved my problem.

If you only get this for select files:
- Go to the Server Published file folder
- Select the problem Files
- Properties
- Uncheck Read-Only
Apparently this can occur when Source Control non-checked out files are read only, and then someone just copies specific files.
(I tried other people’s suggestions: giving myself write access to wwwroot, running VS as admin, but for me it was the read-only that did the trick.)

If you have already published your solution and now it is not publishing, then run the Visual Studio on Administration mode and then publish it.

In my case, I already tried to uncheck the ‘Read-only’ in the problem folder and files but still doesn’t work. I already run the VS as administrator. What I did is just simply restart the visual studio and publish the project again, and it solves the problem.

We had to add full path to publish location. So whereas the publish location used to be:
webtest1W_Apps
We did this:
webtest1D$webdataIntranetDeptsSOW_Apps
and then we didn’t have the error message

The solution for me was to recycle the Application Pool for the website in IIS. I had this problem (access denied) for a few of the folders in the publish directory and none of the above solutions worked for me. After I recycled the app pool, I was able to publish with no problems.

it has permission problem of your web server
You must go to physical address of your website and share in with user of ftp account that you’ve create before and and your problem solve

Are you LOCAL administrator to your own PC? If not, that could be the problem and it’s how I solved the issue at work.

This is a permission issue. I solved this by giving Full control under ‘Security’ tab for Users for the deployment folder.
answered Nov 18, 2019 at 18:07
I had same issue. I have followed the below steps to fix the issue:
First of all you have to identify that which account you are accessing visual studio. In my case, I have used my organization account.
- Go to your deployment which you set as «Target Location» in publish
profile - Right click the deployment folder
- Go to Security tab
- In the list of users, identify the account using which you are
accessing Visual Studio ( in my case organization account) - Grant full permission by checking the check box «Full control» and click
«Apply»

Microsoft Exchange Servers enforce strict restrictions on Email sending limits to keep accounts safe.
If your account exceeds this limit, you may get blocked by your Exchange server.
And, Office 365 users see an error like this “550, 5.1.8, Access Denied, Bad outbound sender”.
At Bobcares, we often resolve such email errors as a part of our Technical Support Engineers Services for web hosts.
Today, let’s discuss the top 2 reasons for this error and how we fix them.
“550, 5.1.8, Access Denied, Bad outbound sender” error – What this means?
When an Office 365 user sends too many emails, it bounces with the following error.
550 5.1.8 Access denied, bad outbound sender AS(41000001) Your message couldn't be delivered because you weren't recognized as a valid sender. The most common reason for this is that your email address is suspected of sending spam and it's no longer allowed to send messages outside of your organization. Contact your email admin for assistance.
This error indicates that Office 365 has added this user to the blocked sender list suspecting spamming.
And, the Exchange server can’t identify the validity of the user as the user’s mail directory is disabled.
“550, 5.1.8, Access Denied, Bad outbound sender” error – Top 2 reasons
Office 365 block emails when the email sending limit of a domain is reached.
The top 2 reasons for a domain to reach this limit are:
- Sending bulk emails – An Office 365 user sends bulk emails like newsletters, campaign emails, etc. which exceeds the specified message limits.
- Compromised email account – The user’s account has been compromised and used to send spam mails. Or, someone spoofed your email header and sent spam mails.
How to fix “550, 5.1.8, Access Denied, Bad outbound sender” error?
You need to unblock the user account from Exchange admin panel.
But, we can’t just unblock a malicious/problem account.
Our Support Engineers, does certain checks on the user account that include:
1. Check if the account is compromised or not
We perform a detailed email log analysis via Message Trace to get the type of emails sent from the user account.
Also, we analyze the Email activity of this user account from the Reports section to identify the volume of emails sent.
Using these details, we’ll confirm whether the email account is compromised or not.
2. Unblock the account
If the email account is safe, we’ll unblock the account using the below steps.
- Go to Exchange Admin center > Protection > Action center.
- Find out the blocked user.
- Click Unblock Account in the description pane.
- Click Yes to confirm the change.
If the email account is compromised, we’ll unblock the account and suggest the user to follow the below security steps.
- Reset the password of the email account to a stronger one.
- Scan his local machine using standard antivirus to confirm if it’s compromised or not.
- Make sure Windows updates are enabled in his machine.
- Remove any auto forwarders or auto-replies set for this account so that hacker can’t regain access to that account.
- To prevent email header spoofing, enable DKIM record from the DNS management area.
Conclusion
“550, 5.1.8, Access Denied, Bad outbound sender” can occur when Office 365 blocks a user account. Today, we’ve seen the reasons for this error and how our Support Engineers fix this.
