An Outlook replacement. The new web Outlook is absolute garbage with zero addin api like the old one had
Make a replacement Outlook that connect to imap service or something that's close to feature matching (calendaring ect) and its game over for two huge revenue streams. it's a cornerstone of Enterprise 365 and they refuse to listen to clients.
Everything else is "good enough" in FOSS but nothing gets close to Outlook functionally.
Thunderbird is way better than Outlook
That's a very ignorant take.
There are plenty of Outlook replacements for Windows AND Linux.
What Linux doesn't have is IAM, MDM and DLP comparable to what Entra ID + Intune (or Active Directory + SCCM) gives you.
That's a extremely ignorant take.
No alternatives come close at all, not even a little. I suggest you install outlook in an enterprise environment.
And yes Linux most certainly does for the latter. You're stuck thinking you need a "server" or service to get the same function of control. You dont, at all.
No, you have a ignorant take. Outlook is dated compared to modern alternatives
Mate, I MANAGE Outlook in my enterprise environment.
Sure, I guess if you have some very specific add-ons as a requirement, it might be difficult. But these things are dying out, 99% of the time Outlook is being used only for email and nothing else. In such scenarios Thunderbird is perfectly fine.
Now, without MDM/DLP/IAM it's literally illegal to introduce Linux in many environments. Any business handling finances MUST be compliant to regulatory standards, and those require these systems to be in place. Without those three you lose your license and literally just cannot do business anymore.
Highly doubt it, maybe a small organisation which would make sense by your comments.
Outlooks feature list is huuge. Large list of functions in Calendering alone is unmatched.
Bollocks.
The API is the backbone for large organisations that extends that large amount of Outlook functions beyond 365 limited services. That is being cut off in an anticompetitive move by Microsoft. It allows for information management and automation to be verified by people with simplicity and a familiar UX.
It's not "bollocks", it's a fact. Lots of businesses that go cloud replace API calls with external apps. People used to do human resources management via Excel and Outlook with macros and plugins, now they use BambooHR or Workday, for instance.
Of course there will also be lots of businesses that don't, but I haven't seen that in the last 13 years of working in the field. And in that time I went through companies as small as 200 users to as large as 180 000 users.
Agreed. Kinda. Email should be email, nothing else. It's not secure enough for anything else. If you want fancy features, get a fancy app that can do them, maybe have it send notifications to your mailbox, that's it.
With this I don't agree. Again, email is email - third party (or custom) software can do these things infinitely better. As for "familiar UX" - come on, it's 2025. If someone can't handle a new UI/UX, they shouldn't be doing office work.
You must not be much of an enterprise admin if you don't know that there are MDM, DLP, and IAM solutions for Linux.
Source: I manage all of those for Linux in an enterprise environment.
What tools are you using. The only one I know of is Fleet
We use Palo Alto for mdm and dlp, and Duo for IAM. Unfortunately we use AD too, but like 90% of our devices are windows so using another solution wouldn't make sense.
Does Palo Alto have a MDM offering? They are a firewall company.
I also personally really like AD. (You can domain join Linux systems anyway)
Yeah, they have Cortex XDR which does endpoint protection and management. We also utilize Ivanti for MDM.
I would really appreciate it if you stopped putting words in my mouth. I didn't say these tools don't exist, did I?
Out of curiosity: which ones do you use?
