How to install Skype for Business for Android v6.25.0.27 on Android API 17+
Takes about 2 minutes. You'll need roughly 42.4 MB of free storage.
- Grab com.microsoft.office.lync15_102301723.apk — hit the Download button above (42.4 MB). If your browser warns about APK files, choose Keep or Download anyway — that warning fires on every APK, not just this one.
- Trust your browser to install — on Android 8+ go to Settings → Apps → Special access → Install unknown apps, pick the app you downloaded with (Chrome, Firefox, Files, etc.), and flip Allow from this source. On older Android, toggle Unknown sources under Security.
- (Optional) Verify the file — compute the MD5 of the downloaded APK and make sure it matches 13bd633f2e750c27…. Any difference means the file is corrupted or tampered — delete and re-download.
- Open the APK — tap the download notification, or find com.microsoft.office.lync15_102301723.apk in your Files app under Downloads, then tap it. Android's package installer will appear.
- Check the signer — the install screen will name the publisher. For this build it should read CN=Microsoft Corporation Third Party Marketplace (Do Not Trust), OU=Android Marketplace Signing for Microsoft Office, O=Microsoft Corporation, L=Redmond, ST=Washington, C=US. If it doesn't match, cancel — you have the wrong file.
- Review permissions & tap Install — scroll the permission list, then confirm. If Play Protect flags it, tap Install anyway (this APK was scanned as TRUSTED).
- Done — open Skype for Business for Android — tap Open on the install screen, or find the Skype for Business for Android icon in your app drawer (this build targets armeabi devices).
Common install errors for Skype for Business for Android
- "App not installed" — usually means an older or differently-signed version is already on your device. Uninstall it first, then retry. Your data may be lost unless you back it up.
- "Parse error" — the APK is for a newer Android than yours. This version needs Android API 17 or later. Pick an older build from the versions list below.
- "There was a problem parsing the package" — the download was interrupted. Delete the file and re-download over Wi-Fi.
- Works on one phone but not another — this build ships armeabi native code. Devices with a different CPU will reject it.
