Nothing is more annoying than not being able to get your email when you want it and be presented with a sometimes very cryptic or a seeming meaningless error code instead.
Although there are a multitude of error codes that you could be presented with, there are a couple of common solutions that work for many cases.
Aside from offering common solutions, this guide also contains a list of send/receive error codes which you may encounter and their meaning. For certain error codes, a more specific solution is mentioned.
- Other send/receive issues
Outlook 2011 was introduced for Mac users and can be compared with Outlook 2010. Similar features of Outlook for Windows can be seen in Outlook 2011 such as, emailing, contacts storing, calendaring etc. Though it holds the features of Windows Outlook, cannot be said that it is the exact copy of Outlook Windows. I googled the title of the thread, Outlook 17900 error, and it listed a number of Microsoft support pages that tell how to solve the problem. If none of those have been tried yet, I recommend starting there, with Microsoft's support pages.
Check your email account settings.
If you just configured your mail account and are directly presented with a send/receive error, you should start with verifying if your account settings are correct. You can get this information from your ISP or email administrator. Settings for several large free email providers can be found here.
When you are trying to send a message from another network than the network where the mailbox is located (for instance, from a hotel or a Wi-Fi hotspot, then you need to enable authentication for the configured SMTP server as well.
When Outlook worked before and you’re suddenly presented with send/receive errors, it is still good practice to verify your account settings and make sure that they are current. For example, several ISPs have increased their email security settings which could require you to enable TLS/SSL or make port changes. Also, sometimes they have merged with other ISPs and decommission the old account settings over time requiring you to make changes.
Trying your account settings on another computer or creating an additional mail profile for testing could help you determining if it is an issue with your current account configuration settings.
Disable virus scanner integration.
Virus scanners which integrates themselves with Outlook are a known source of causing all sorts of send receive issues. For instance, the following time-out issues are often a result of this;
- The operation timed out waiting for a response from the receiving (POP) server.
- A time-out occurred while communicating with the server.
Other issues that are often caused by having a virus scanner integrated with Outlook are;
- Outlook being very slow in collecting your email.
- Messages ending up stuck in your Outbox (also see below).
- Messages being sent but never received.
- Sending or receiving blank messages.
- General message corruption;
- Font too big/small.
- Message not displaying at all.
- Meeting invitations being converted into regular emails.
Disabling your virus scanner’s integration with Outlook does not compromise your security as you’d still be sufficiently protected by the on-access scanner part of the virus scanner. For more details see; Disable virus scanner integration?
Check your firewall settings.
Firewalls can block incoming and outgoing traffic so make sure that Outlook and/or the required ports for email are listed as an exception to go through.
If you are presented with send/receive errors after updating Outlook, you probably need to reconfigure your firewall to re-allow Outlook to pass-through again.
This is because several firewall solutions verify via a hash that it is indeed the correct outlook.exe that is trying to pass through the firewall and not some virus which named itself outlook.exe. As with most updates the outlook.exe gets updated as well, you’ll need to accept it as safe again. You can find more information about this in the manual of your firewall solution.
Issues with add-ins
Aside from virus scanners, there could be other add-ins installed which integrate itself with the send/receive process of Outlook. Loading Outlook in Safe Mode is a good first step to see if add-ins are indeed the cause of the issues.
To further troubleshoot add-ins, manually disable each of them and re-enable them one-by-one to find the culprit.
Check data store integrity
If there are issues with the delivery location (your Outlook mailbox), then this could result in send/receive issues as well.
Checking the integrity of your delivery location can be done with scanpst.exe. Also verify that the data store isn’t full or that it needs to be converted from ANSI to the Unicode format.
If you are using an Exchange account, then you could also try it with Cached Exchange Mode disabled and see if it works correctly now. If it does, rename the ost-file to .old and have Outlook rebuild the ost-file or verify that the configured location for the ost-file in your account settings is valid.
Outlook Error Code 17900
Stuck message or hidden read receipt
A stuck message is also often a source of having send/receive issues.
While it is easy enough to spot a message stuck in your Outbox, in some cases the stuck message can be a Read Receipt which are hidden messages and thus much harder to recognize as the issues and to delete.
Other send/receive issues
Below is a short list of other common send/receive issues which you could encounter but which are not directly identified by a send/receive error.
- Password prompts
In some cases Outlook can not remember your password for your mail account which results in being prompted for it. - Receiving duplicates
When you receive multiple copies of a message or receiving the same message(s) over and over again see this guide. - Rules not being processed automatically
When you have rules configured but they are not executed automatically when you receive new emails, see this guide. - No automatic send/receive upon starting Outlook or cannot edit Send/Receive settings.
In those cases, reset your srs-file by renaming it to .old.
Send/Receive error codes
Searching in the error list below probably goes best with the Find function of your browser. For most browsers the keyboard shortcut for the Find function is CTRL+F.
When typing in the error code, please note that the error code starts with the digit 0 and not with the letter O.

Enhanced Mail System Status Codes
Aside from getting the reported errors, there usually also is another error code listed. These error codes consist of 3 digits which could be separated by a dot. For instance; 553 or 5.5.3
These errors could also be sent to you in an email (usually from System Administrator) with a Delivery Status Notification code in it.
The first number will tell you the general status of the message;
- 2
Success. The message has been delivered. - 4
Persistent Transient Failure. This means that the message was valid and accepted by the server but there is a temporary problem which prevents it from being delivered. The mail server will usually try to send it again later until a time out is reached. Until you get the a message that the server is giving up (see “5” below), there is no direct need to resend the message. - 5
Permanent. This is a fatal error and the message sent cannot be delivered. It’s unlikely that the message can be delivered by a simple resend. A change must be made either within the message (wrong address, too big, too many recipients, etc), within the account settings or at the mail server of the sender or receiver.
The second 2 numbers will give you more details about why the message is delayed or failed;

Other error codes
Error Code 17900 Outlook For Mac
Aside from the above listed error codes, there are many more error codes which you could encounter during send/receive. These usually refer to internal errors from Outlook, are specific to a certain mail server or are actually coming from your virus scanner or another add-in that integrates with your send/receive or networking process.
Due to the nature and origins of these error codes, the list below will probably always remain incomplete. If you encounter a new send/receive error, have a better description or even a solution for it, please email it to me (preferably with a screenshot of the error attached) and I’ll update the list accordingly.

However, you might not find the given workaround as fruitful as expected, because it does not fulfill the task every time and the error continues to occur. In such cases, it is a wise idea to repair corrupt Mac Outlook backup files (.olm), and restore all the lost or inaccessible mail items in Microsoft Outlook for Mac 2011. Such repairing can be done using Stellar Repair for OLM.
This application will help you recover mail items, such as email messages, contacts, attachments, tasks, calendars and notes. It will also help in severely corrupt OLM files. These applications are built by experienced software developers hence are great at performing data recovery. Furthermore, they are widely available over the web and can be purchased by placing an order online.
