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.
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.
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.
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.
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?
