Microsoft recently announced that they will no longer use TLS 1.0 and 1.1 in Office 365. They are moving all online services to Transport Layer Security (TLS) 1.2+ to provide best-in-class encryption, and to ensure the service is more secure by default.
“We temporarily halted deprecation enforcement of TLS 1.0 and 1.1 for commercial customers due to Covid-19, but as supply chains have adjusted and certain countries open back up, we are resetting the TLS enforcement to start Oct 15, 2020,” Microsoft announced.
Yes, but what does that mean?
In short – Microsoft is switching to more secure security and subsequently older operating systems will no longer work effectively. At Stellenbosch University this means that, once this change takes effect, all connections to Office 365 using the protocols TLS 1.0 and TLS 1.1 will no longer work. This includes:
- Android 4.3 and earlier versions
- Firefox version 5.0 and earlier versions
- Internet Explorer 8-10 on Windows 7 and earlier versions
- Internet Explorer 10 on Windows Phone 8
- Safari 6.0.4/OS X10.8.4 and earlier versions
OK, what should I do?
It’s important that you update or replace the software mentioned above and the devices that rely on TLS 1.0 and 1.1 to connect to Office 365.
- Windows based devices
Make sure all Windows and Office updates are installed.
We recommend Windows 10 v1909 and Office 365.
If you are running Windows and Office versions other than Windows 10 and Office 365, please log a request on the ICT Partner Portal to have your device assessed for possible upgrade to our recommendations. - macOS devices
Make sure all system updates and Office updates are installed.
We recommend macOS Mojave and higher and Office 365.
If you are running a macOS device or Office package older than our recommendations, please log a request on the ICT Partner Portal to have your device assessed for possible upgrade to our recommendations. - Android and iOS devices
Need to be updated to latest available update for the device as specified by the manufacturer of the device.
We recommend that you use the Outlook app to be able to access your emails from the device as this is the most secure application to retrieve your emails.
If your device does not meet the requirements to upgrade its Operating system and Software, we recommend that you purchase a device that is compatible to continue to be able to make use of these services. If you are still unsure of what to do, please log a request on the ICT Partner Portal and we will assist you.

Microsoft het onlangs aangekondig dat hulle nie meer TLS 1.0 en 1.1 in Office365 gaan gebruik nie. Alle aanlyndienste word geskuif na Transport Layer Security (TLS) 1.2+ om die beste inkripsie te verskaf en ook te verseker dat die diens by verstek veiliger is.
“We temporarily halted deprecation enforcement of TLS 1.0 and 1.1 for commercial customers due to Covid-19, but as supply chains have adjusted and certain countries open back up, we are resetting the TLS enforcement to start Oct 15, 2020” het Microsoft gesê.
Ja, maar wat beteken dit?
In kort – Microsoft skakel oor na veiliger sekuriteit en gevolglik sal ouer bedryfstelsels nie meer effektief funksioneer nie. By Universiteit Stellenbosch beteken dit dat, sodra dit in werking gestel word, alle verbinding na Office 365 wat die TLS 1.0 en TLS 1.1 protokolle gebruik, nie meer sal werk nie. Dit sluit in:
- Android 4.3 en vroeër weergawes
- Firefox weergawe 5.0 en vroeër weergawes
- Internet Explorer 8-10 op Windows 7 en vroeër weergawes
- Internet Explorer 10 op Windows Phone 8
- Safari 6.0.4/OS X10.8.4 en vroeër weergawes
Goed, maar wat moet ek doen?
Dit is belangrik dat jy die sagteware wat bo genoem word opdateer of vervang, sowel as die toestelle wat staatmaak op TLS 1.0 en 1.1 om te verbind aan Office 365.
- Windows-toestelle
Maak seker dat alle Windows en Office opdaterings installeer is. Ons beveel Windows 10 v1909 en Office 365 aan.
Indien jy enige ander weergawes buiten Windows 10 en Office 365 gebruik, teken asb. `n versoek aan op die ICT Partner Portal sodat ons kan bepaal hoe jou toestel volgens ons aanbevelings opgradeer kan word. - macOS-toestelle
Maak seker dat alle stelselopdaterings en Office-opdaterings installeer is. Ons beveel macOS Mojave en nuwe aan, sowel as Office 365.
Indien jy `n macOS-toestel of ouer Office-pakket gebruik as wat ons aanbeveel, teken asb. `n versoek aan op die ICT Partner Portal sodat ons kan bepaal hoe jou toestel volgens ons aanbevelings opgradeer kan word. - Android en iOS-toestelle
Gebruik die nuutste, beskikbare opdatering vir die toestel soos gespesifiseer deur die vervaardiger.
Ons beveel ook aan dat jy die Outlook-toepassing gebruik om e-pos op jou toestel te lees aangesien dit die veiligste toepassing is om e-posse te kry.
Indien jou toestel nie aan die vereistes voldoen om die bedryfstelsel en sagteware op te gradeer nie, beveel ons aan dat jy `n nuwe, versoenbare toestel aankoop sodoende steeds hierdie dienste te kan gebruik. Indien jy steeds onseker is oor wat jou te doen staan, teken asb. `n versoek aan op die ICT Partner Portal en ons sal jou help.
