Outlook 365/2016 keeps randomly dropping connection to MS Exchange server

Hi Frank,

Would you please provide the following information to analyze the situation ?

- What's version of Outlook client are you using ?

- What's version of your O.S. ?

- Have you tried using Outlook Web Access and see if the similar problem occurs ?

- Would you also check if your O.S. has installed latest updates ?

Furthermore, Would you please Disable Hardware Accelerator and see if the issue still occur ?

Hi Jatin.

I am using Outlook 2016 and it was updated today along with the OS which is Windows 10 64bit. I don't know where to look to find the build version, if that is what you mean.

No, I haven't tried the Outlook Web Access but I will after this.

I have just now disabled the Hardware Accelerator but I trust this switch only applies to Outlook and is turned back on when I close Outlook down. (I run 2 x SLI cards for videoediting and won't wish to lose any punch there.)

Windows Update is set to automatic and did its thing about 6 hour ago.

Outlook dropped in and out while I was typing this reply.

I will now reboot and see if anything changes.

Hi Frank,

Yes, sure please try and let me know if after Disabling Hardware Accelerator in Outlook , does it resolves the issue or not ? No worries, it will not affect your working experience in Outlook.

And also it happens in OWA or not ?

I won't be able to tell for a while as the dropouts are unpredictably. However, disabling the hardware accelration has killed the SLI setup which will be a bit of a nuisance. I am about to swith to OWA and see what, if anything happens. It may not do a thing tonight.

Sure.. Just try it and let's see if it works or not.

However again double confirm in simple words, After Disabling is it still crashing ?

Can't say yet as it is not predictable. Still listening for the alarm sound that tells me if Outlook drops - then re-acquires - the server. Nothing has happened as yet since disabling hardware acceleration.

It's been a couple of hours now and I haven't heard the alarm go off so this might be it, Jatin. I'll get back to you tomorrow if anything changes but I am not sufficiently an optimistic to state that my problem has been solved as of this moment.

It is still a bummer than my SLI arrangement is disabled when I turn off hardware acceleration, but I guess I can live with that as I only really need it for video editing and I can turn it on pretty easily.

Thanks for you help.

Hi Frank,

That's great to hear.

[my SLI arrangement is disabled when I turn off hardware acceleration] Have you disabled Hardware Accelerator for Outlook only or completely for your system ? My suggestion is for Outlook Client only to Disable.

Thanks for your understanding and cooperation..

Thanks, Jatin. I disabled hardware acceleration inside Options/Advanced for Outlook, but it disabled SLI for the whole computer. I re-enabled it but the computer became unstable and was doing weird things. As an example, one folder full of the recent output from a video project would consistently hang when I tried to change the View to Details. I coped the folder to another disk and it worked fine. I scanned the disk...anyway that's another problem so I won't go there, but thanks to your help, I think I am a good way down the road.

Regards

Frank

Hi Frank,

That's glad to hear. Could be the issue due to Hardware/Graphic card, however I believe it worked as suggested.

Disabled Hardware Accelerator in Outlook and issue has been resolved.
