Temporary server error. Please try again later ATTR5
Hello,
We have a problem about sending email to Office 365 - outlook.com users. You can see the sample error code below. I have contacted with Office 365 and our ip is not blacklisted on their side. What can be the cause and the solution?
Thank you.

Looks like you may not be the only one You can search for " Temporary server error. Please try again later ATTR5 " in a search engine and you will get links like this one 451 4.4.4 Temporary server error. Please try again later ATTR5 An older thread from MS suggested it was something to do with their licensing, and yet other blamed firewalls. Perhaps you need to do some further checks. 0 -
Hello, It looks like it's still an issue as of today, based on the thread in the previous response: 451 4.4.4 Temporary server error. Please try again later ATTR5 You may also want to reach out to Microsoft's support team again if the issue continues. Thank you. 0 -
Also having this issue, as are many people. It seems to be a problem with Outlook 365's security certificates failing Postfix's certificate verification. I suppose we could turn this feature off somehow - does anyone from cPanel know how we might go about that? As another alternative for anyone having the same issue, I have temporarily set up an email relay, until this issue is fixed. My new problem though, is that some of the IPs our SMTP relay provider uses have been blacklisted by some spam lists (because of spam by their other customers). I'm not familiar enough with Exim configuration to know how to do the following (and can't find anything in Google), but it feels like it should be possible. If anyone has any idea how to configure cPanel so that it sends email through our local mail server by default, and uses the relay for emails that have received the 451 error, that would be the perfect solution. Does anyone know how to set that up, or know an email technician that may be able to help? Thanks! 0 -
Anyone have any updates on this? I'm going on four days with this problem and no one at Microsoft gives a damn (they won't even reply) because for the majority of users it seems to be fixed. Not me though! Is it possible to set up an SMTP relay for ONLY the emails that go to Office 365 servers? At least I can get them out of the queue for a while. Or some way of testing and verifying if it's the Postfix certificate verification that's causing the issue? Thanks. 0 -
No updates from anyone - rather frustrating! Emails are still sitting in our mail queue, manually clearing them out through the relay several times each day, but we can't keep this up forever. Would appreciate hearing back from someone at cPanel and whether there's a fix we can implement on the cPanel end for this? I know it's Microsoft's fault, but it seems to be a widespread problem for cPanel users. 0 -
I probably need to set up a relay as well then because I've had emails queue for almost a week now. It does appear to be with Microsoft. I'm able to reach some office office users, but none on a certain IP range (which is what everyone in my country uses). Those on that Ip range don't resolve from pinging either. However, according to Office 365 support the emails aren't reaching their server at all. So the ND message isn't coming from Microsoft, it's coming from cpanel. Any chance of cpanel support giving some info on what this error really means? 0 -
This issue seems to have finally been fixed. My email queue has been clear for the last hour. Hopefully it's fine for everyone else now too :D 0 -
Same here, as of about 2 hours ago it started moving. 0 -
Hello, I'm happy to see the issue is now addressed. This does not appear related to any Exim configuration values, and instead looks to have related to an issue with Microsoft's servers. Thank you. 0
