Did it...not have that already? I swear it did, but honestly I thought Exchange was dead long ago.

Until now, Thunderbird users in Exchange hosted environments often relied on IMAP/POP protocols or third-party extensions

Exchange is very much kicking and Thunderbird had ews support for some time but it was in beta.

I'm glad they have it but adding EWS support at the end of 2025 is nothing to brag about. EWS came with Exchange 2007, almost 20 years ago!

Yeah but it looks like this includes support for organization Office 365 accounts, so it's not just something that only worked 20 years ago. If it only supported outdated Exchange servers that would be one thing, but it seems to support modern ones.

Microsoft announced a while back that the end of EWS is coming for exchange online which means M365 accounts. They will start blocking EWS requests from October next year and only support access via Graph API. I understand the Thunderbird team are also working on Graph API support.

EWS EOL

Sure but as @ApeNo1@lemmy.world noted MS is ending support for EWS in M365 in less than 12 months! So it took them 18 years to release something that still doesn't fully work (no Calendaring support, WTF?) and won't even be usable by this time next year.

🤦

If it only supported outdated Exchange servers that would be one thing

The only Exchange server that ISN'T outdated at this point is the 4 month old Exchange Server Subscription Edition. All other versions are now EoL and have no support. So unless you have a very particular need to keep your EX environment On-Prem then you may as well migrate to EXO.

If you are already using EXO then Thunderbird's new EWS support will stop working next October.

Yay! Now do Windows and Syslog, or windows and SNMP.

Mihies@programming.dev · 0 pts · 282d

Yep, but still better than never 🤷‍♂️. I was really looking forward to it as I recently migrated from Windows to Linux only to find out that it doesn't work for me for some reason.

Great! We can get (almost) a whole year of using it with Exchange Online before EWS is turned off!

Doorknob@lemmy.world · 3 pts · 281d

They've said that this is a big stepping stone towards support for Microsoft's graph api and lots of on-prem servers will still be using EWS for ages to come.

Awesome. I really needed this about 5 years ago, but I'm glad they've added it for sure.

I've been using Nine as exchange client since 2014, it's working great. Didn't receive any updates in well over a year though, but that's hopefully because there's nothing needed.

So Microsoft is going to ditch exchange soon?

sturmblast@lemmy.world · 3 pts · 281d

I wish

Awesome! Previously, Evolution was the only Linux client which supported Exchange, and Evolution is… well…. 😕

I hate Exchange so much.

Appoxo@lemmy.dbzer0.com · -1 pts · 281d (4 replies)

Better than just having imap (So difficult to sync contacts and calendar)....

corsicanguppy@lemmy.ca · 3 pts · 281d (1 reply)

So difficult to sync contacts and calendar

If only there was a well-defined protocol in a series of RFCs for that, AND people could use more than one protocol in a binary.

Appoxo@lemmy.dbzer0.com · 1 pts · 281d

You mean WebDAV and CalDAV?
Why use twenty protocols, when you could use only one?

macaw_dean_settle@lemmy.world · 2 pts · 281d (1 reply)

I have never had an issue for my clients.

Appoxo@lemmy.dbzer0.com · 0 pts · 281d

I don't have any problem with imap.
But Exchange bundles all syncing very neatly.

I wonder if the hatred would be the same if it was developed/designed by L.Torvalds...
