The short version
Passing AZ-802 earns the Microsoft Certified: Windows Server Administrator Associate credential, and that credential is valid for one year. You keep it by passing a free, open-book renewal assessment on Microsoft Learn before it expires. If you fail the exam itself, you wait 24 hours for the second attempt and 14 days between later ones. Everything here comes from Microsoft Learn pages read on October 22, 2026.
Does the credential expire?
Yes. Microsoft states that associate and expert certifications, along with specialty ones, are valid for one year from the day you complete all requirements. For this credential, AZ-802 is the exam that completes them, so the clock starts when you pass. Fundamentals certifications are the ones that never expire; this is not one of them.
Microsoft’s stated reason is simple: technology moves, and a yearly check keeps the credential tied to current skills. Your expiration date appears in your Learn profile.
How renewal works
Renewal is a short online assessment, not a second sitting of the exam. Microsoft describes it this way:
- It is free. There is no fee for the assessment.
- It is open book and unproctored. You take it on Microsoft Learn, on your own, and you can look things up.
- It is shorter than the exam. It focuses on recent changes. Microsoft’s FAQ puts it at about 45 minutes.
- It opens six months before expiry. You cannot take it earlier than that. Expiration times are in UTC.
- Passing extends the credential by one year from the current expiration date. Taking it early does not cost you time, because the new year is counted from the old date. The new date shows on your profile immediately.
- There is no attempt limit. If you fail, you can try again right away. After the second try, you wait at least 24 hours between attempts. Just pass before the expiry date.
You find the assessment in your Learn profile: open Certifications and look for the blue Renew button. If you agreed to Microsoft’s communication terms and have an email on your profile, you also get a reminder when you become eligible. Microsoft recommends taking the assessment well before the deadline, so a sick day or a technical problem does not push you past it.
Two things do not count as renewal. Retaking the AZ-802 exam does not renew the credential, and neither does a beta exam. Microsoft says the renewal assessment is the only path and that there are no exceptions.
What happens if it lapses?
If the date passes, you can no longer renew. Microsoft’s expiration policy says you must earn the credential again by passing the required exam, which here is AZ-802. That is a full exam attempt, and the regular retake rules apply, including the fee, which depends on your country and is not printed here.
Exam retakes
If you fail the exam, Microsoft’s retake policy says:
- You wait 24 hours before the second attempt.
- A 14-day wait applies before every later attempt, up to five attempts in total.
- You cannot take the same exam more than five times in 12 months, counted from your first attempt. After five failures, you become eligible again 12 months after that first attempt.
- You pay for each retake, if a fee applies.
- You cannot retake an exam you have passed, unless the credential has expired.
A waiver of the waiting period exists only if an internet or equipment failure during the exam produced a Pearson VUE case. You must supply the case number when you ask Microsoft Credentials support. Nothing else qualifies.
The waiting periods suggest a plan: after a failed attempt, use the score report. It shows a bar per skill area, though not the questions you missed. Target the weakest areas, run a timed practice set, and book the next date when your results are steady. Our exam format page explains how the score report reads.
What if the exam changes or is retired?
AZ-802 shows no retirement date on Microsoft’s exam page. Microsoft does update exams from time to time; English comes first, and AZ-802 is currently offered only in English. The retirement notices on the older AZ-800 and AZ-801 exam pages show how a change looks in practice: both read “retired on September 30, 2026”, and AZ-802 is the exam listed for the credential now.
For retired credentials, Microsoft’s expiration policy says they stay in the Active section of your transcript until they expire (or for two years after retirement, if they have no expiry). Its renewal FAQ adds that if a retirement date comes before your expiry date, the renew-by date on Learn takes the retirement into account. Microsoft’s pages do not describe a special route from AZ-800 and AZ-801 to AZ-802, so check your own profile for what applies to you.
A timeline example
This is an illustration, not a prediction. Say you pass AZ-802 on March 1, 2027.
| Date | What happens |
|---|---|
| March 1, 2027 | You pass. The credential is valid for one year. |
| March 1, 2028 | Expiration date. |
| September 1, 2027 | Six-month window opens. |
| January 15, 2028 | You pass the renewal assessment. |
| March 1, 2029 | New expiration date (one year from March 1, 2028). |
If you miss March 1, 2028, you start over with AZ-802.

Frequently asked questions
Can I renew early?
Not more than six months before the expiration date. Within that window, renewing early is fine, and the extra year is counted from the old expiry date.
How many times can I fail the renewal assessment?
There is no limit. Retry immediately after the first failure; after the second, wait at least 24 hours between attempts.
Does renewing cost anything?
No. Microsoft says renewal is free for anyone holding a valid associate, expert or specialty credential.
