For a few years I'm noticing more and more weird and unexplainable behaviour in Outlook. We support mostly 365 Exchange Online clients on Windows workstations or RDS environments.

The amounts of unexplainable bullshit we face is staggering. Outlook not being able to open the folder set, weird MFA glitches, weird bugs in the UI and downright weird errors coming from nowhere is some of the stuff we face weekly.

Am I alone on this?

Outlook classic is on life support. Next October Exchange Online drops support for it.

It’s built on decades of code. It allows plugins to directly affect the UX. It still uses I explore at times.

I switched to new outlook and while it has its own significant issues, at least it’s not spaghetti code. It also runs on top of Edge, which allows Outlook devs to ignore a lot of backend code, and makes the UX pretty consistent across platforms.

Sadly I'm still bound to classic Outlooks because of a lot of clients dependent on COM add-ins.

Yeah those com addins are usually the problem with outlook stability. Simply moving to modern addins improves Outlook classic significantly.

There is no simply moving here sadly, the plugins simply aren't available. Hooray for vendor lock-ins.
