New Outlook memory usage

Question

Old Outlook has a reputation for bloat. I used Task Manager to see how much memory Old vs New use. I was amazed to see that New Outlook uses over 1GB on my system. The "bloated" Old Outlook uses around 200MB. I thought that New Outlook was based mostly in the cloud. And with 1GB of memory, they still have a product that doesn't work as well, nor have as many features, as the Old one. Software design has changed a lot since I was doing it back in the 70s - 90s. Maybe we really should let AI do it.

Answer 1

I am having the same issue which started last Friday. At the moment I cannot even use the new Outlook as it crashes and slows my whole computer, making the fan spin like crazy. I have to use the web version or the old outlook. Restarting does not fix the issue.

Edge is also consuming lots of memory for some reason.

Also, what are these Edge WebView2 processes. It says that I have 17 processes running in Edge, but I only have 5 tabs open.

Please fix this ASAP Microsoft.

Answer 2

Just to continue this thread, today I've had multiple people in our organization ask me why they suddenly seeing pop up messages on their computers warning of high memory usage and suggesting a restart. BTW, a restart did nothing to help the situation. Looking in task manager, you could see the resource usage was "Very high".

We have been pro-active in urging users to try the new Outlook and get used to it before the old Outlook is no longer available. We thought it would ease the transition. Today, after the memory messages started on multiple computers, the new Outlook became unresponsive to the point where you would have to go into task manager just to close the application. Upon reopening it, you could not click on to preview an email or even open an email. Right now, for those users, the only recourse is to have them go back to the old Outlook.

I sincerely hope that these problems can be addressed before MS tells us we can no longer use the old Outlook. If that happens, we'll SOL.

Answer 3

My Outlook was sitting at 33GB of memory usage and causing my Mac to spit out a memory usage alert this morning. I can understand a GB or 2 at the most, but 33 GB? What's going on with Outlook?

Answer 4

I have the same issue and tried to open the classic one. Then I could find out that the problem was related with the reminders. It shows me all the reminders since I have the current account at the same time (oldest one from 198 weeks ago).

I guess new Outlook collapsed due to this fact. Once I discarded the reminders it worked fine again. Hope this helps other people with the same issue.

Answer 5

I get that you're trying to be helpful, but I can't understand why MS released this new version with the number of bugs and not thought through impacts it has on general MS Outlook usage. I'm using new MS Outlook now on a development workstation with nothing else open and it is reporting high memory utilization. What's wrong with this picture? What QA process was used when MS tested this for this to be so prevalent a problem?

Also, why does Microsoft decide to use a commonly use key for editing, namely the backspace key, to mistakenly archive an email in the middle of trying to edit one?
