attack simulation training payload link is blocked by safe links at t

Not specified by the original author.

TL;DR

Add the simulation vendor's payload domains to the Safe Links allow list and the attack simulation payload configuration as Microsoft documents, and test a click end to end, because Safe Links will rewrite and block an unregistered simulation link exactly as it should block a real phish. Prove it on one affected message before rolling it to the rest of mail on that sending or receiving path, because this fault repeats identically wherever the same condition holds and a fleet-wide or batch-wide first attempt multiplies the damage when the diagnosis is wrong.

attack simulation training payload link is blocked by safe links at time of click and the simulation records zero clicks

Use this when

• You see this exact error or symptom: attack simulation training payload link is blocked by safe links at time of click and the simulation records zero clicks.
• The failure is in the mail gateway, Exchange Online, Gmail or Yahoo receiving path named in the title, and it repeats on the same action rather than happening once and clearing.
• Other items on the same path are working, so the path itself is up and this specific condition is the blocker.

Not for this skill when

• A different error code, message, or tool is involved. Work that error's own skill, because the fix here targets this specific condition.
• The whole service or platform is down. Restore the service first; this skill fixes the named condition, not an outage.
• You cannot identify one affected item to test on. Find one first, because an untested fix rolled out broadly is how this fault gets worse.

Steps

1. Confirm the fault on one affected message first and capture the evidence before changing anything: check the message trace and the full Authentication-Results and rejection headers for one affected message, read on the receiving side, and record the exact error text, the record or host involved, and the time it happened. Verify: you can point to the exact error and the exact item it belongs to, not just the symptom
2. Add the simulation vendor's payload domains to the Safe Links allow list and the attack simulation payload configuration as Microsoft documents, and test a click end to end, because Safe Links will rewrite and block an unregistered simulation link exactly as it should block a real phish. Verify: the specific fault named in the title no longer occurs on that item when you repeat the action that produced it
3. Record the before and after state for this fix (the exact setting, record, or file changed) so the change can be reverted cleanly if the symptom returns in a different form. Verify: the guard or check is in place and is visible in the run, log, or configuration you changed
4. Retest end to end: send or release one test message through the exact same path and confirm it delivers with the expected authentication results. Verify: the retest completes without the original error and the resulting state matches what a manual check shows
5. Roll the fix out to the rest of mail on that sending or receiving path in the same way, watching the first few for the same error, and note the root cause and the change in the run or incident record. Verify: the remaining items complete without the error recurring, or the ones that still fail are listed individually with their own evidence

Compatibility: Exchange Online and Microsoft Defender, Gmail and Google Postmaster Tools, Yahoo bulk sender rules, Proofpoint, Mimecast, Barracuda and Cisco Secure Email Gateway as named in the title.

Why it happens

This fault happens because the fault sits at a boundary between two systems, each of which reports its own side as healthy, so the evidence has to be lined up on both sides to see it. In this case the condition is the one named in the title, in the mail gateway, Exchange Online, Gmail or Yahoo receiving path named in the title: the receiving or acting side reports the failure faithfully, but the underlying state (a record, a setting, a credential, a file, or a mapping) does not match what that action assumes. Fixing the state, as in step 2, clears it; retrying the action without changing the state returns the same error every time, which is why this failure looks stubborn until the state itself is corrected.

TL;DR

Deliver simulations through the channel Microsoft built for them, not through filter exceptions for real phish: configure the simulation in Attack Simulation Training or your training platform integration, register the simulation domains and senders there, and use the advanced delivery policy for phishing simulation that Defender provides. That path delivers the training mail and records user actions, while a blanket anti-phishing exception would also wave through real attacks that copy the same shape.

phishing simulation emails quarantined by anti-phishing policy instead of delivered to users

Use this when

• Authorised simulation messages are quarantined, junked, or stripped before users see them.
• User clicks and reports on the simulation are not being recorded because mail never arrived.
• The simulation is part of an approved security awareness programme with documented scope.

Not for this skill when

• Real phishing mail is being quarantined. That is the filter succeeding; do not create a delivery path for it.
• A third party test with no approval or scope is blocked. Leave the block in place and route the request through the programme owner.

Steps

1. Confirm the campaign approval, its sender domains, and its target group in the programme records before touching any policy. Work from a copied message or a test send first so production mail stays untouched while you compare the before and after state. Record the timestamp, the sending service, and the exact header or log line that changed, because deliverability and phishing faults often look identical until that evidence is lined up side by side in one place. Verify: the campaign scope and its domains are documented and approved
2. Check where the test messages died: quarantine reason, policy name, and whether links or attachments were stripped in transit. Do not change more than one setting at a time here. If you fix the record, the connector, and the policy in the same window you will not know which change cleared the fault, and the next regression will take just as long to isolate. Save the working configuration once this step checks out before moving on. Verify: the blocking policy and action are named from the quarantine record
3. Configure the phishing simulation section of the advanced delivery policy with exactly the simulation domains, sender addresses, and source IPs from the programme. Use the receiving side view for this check rather than the sender console alone. Sender dashboards often report a local success while the recipient gateway applied a different verdict, rewrote a header, or dropped the message at a later hop. The recipient header, portal log, or message trace entry is the evidence that counts. Verify: the advanced delivery entry lists only the approved simulation identifiers
4. Run a pilot send to a small test group inside the target scope and confirm delivery, rendering, and click and report tracking. Keep any exception you create narrow and time boxed. Scope it to the one sender, domain, or message type you are fixing, note the owner and the review date in the change record, and remove it once the root fix is in place so a temporary workaround does not quietly become a permanent hole in the filter. Verify: pilot users receive the message and their test actions appear in the campaign report
5. Launch the full campaign, then review the advanced delivery entry at campaign end and remove identifiers that will not be reused. Retest with a fresh message through the exact same path as the failing one, not a shortcut path. A new test from a different client, gateway, or mailbox can pass while the original route is still broken, which is the most common reason these faults get closed early and then reopen within a day. Verify: the post campaign review shows the entry removed or confirmed for a scheduled next run

Why it happens

Defender cannot tell an authorised simulation from an attack by intent; it can only use configuration. The advanced delivery policy is the explicit signal that separates the two, scoped to named simulation infrastructure. Admins who instead weaken impersonation or spam rules for a campaign open a real hole for the exact techniques the training is meant to teach users to spot, and the hole usually outlives the campaign by months.

Edge cases to check:

• Simulations sent from lookalike domains you register for training still need SPF and DKIM for those domains, or other receivers will block them.
• Tell the service desk a campaign window is running so real user reports during it are triaged with context, without telling users the exact send time.

TL;DR

A link can be disabled after delivery when a later verdict, a tenant block, or the sender platform disabling the campaign link changes its status. The message users see is generic, so work from the exact URL: check whether it is on your tenant block list, whether the vendor reclassified it, and whether the marketing platform itself retired the link, which happens when campaigns end or tracking domains rotate.

"this link has been disabled" error on legit marketing url

Use this when

• Recipients see a link-disabled error on a current marketing or vendor email.
• The same link worked when the mail first arrived.

Not for this skill when

• The destination was taken over or turned malicious after sending. Keep it disabled and treat as an incident.
• The error appears for every link in every mail. That is a rewriting service fault.

Steps

1. Copy the exact disabled URL from a recipient copy, including its rewritten form, and note when it last worked. Verify: the URL and timeline are captured.
2. Search your tenant block list and admin actions for the domain; a well-meaning block during another incident is a common cause. Verify: tenant-side status is confirmed.
3. Check the URL current verdict with your mail vendor and a public scanner. Verify: whether the vendor now classifies it as malicious, and why.
4. Ask the sender whether the campaign link was retired or the tracking domain changed, since senders disable their own links routinely. Verify: sender-side status is confirmed.
5. Apply the matching fix: remove an erroneous tenant block, submit a false positive, or have the sender resend with live links. Verify: a recipient can open the link successfully.

Variant phrasings

The verbatim error variant.

rewritten link disabled after delivery verdict change

The post-delivery verdict variant.

Compatibility: Defender Safe Links link disabling, marketing platform tracking link lifecycles.

Why it happens

Rewriting creates a live reference, not a copy: the same rewritten link is re-judged at every click. Status changes days later, from any of three owners (tenant, mail vendor, sender platform), all surface as the same disabled message.

Edge cases / pitfalls

• Keep a change log for tenant blocks with ticket references so a later admin can judge intent.
• Marketing tracking domains are shared across many senders. Blocking one affects unrelated campaigns.
• If the sender retired the link, no tenant action can revive it. Set expectations with the business owner.
