All Office 365 slow to open

Now, I have no idea just what you have tried and it is definitely not a problem here as Word starts in about 2 seconds and here it has to load 3 add-ins.

Have you followed the steps in the KnowledgeBase article "How to troubleshoot problems that occur when you start or use Word" at:

https://support.microsoft.com/en-us/kb/921541

particularly the section dealing with Add-ins.

As I said, I have no idea what you have tried so don't get upset if that is something that you have tried.

Doug, thanks for the prompt reply, also for your sharing and caring. Go well.

I have exactly the same issue on my HP Laptop so I guess that we are not alone suffering this
Hope to to get a REAL fix for this better than tricky and hazardous regedit hokus pocus

We are talking about Office 365 (NOT ONLY Word) but any component ; Word, Xls, PPT etc...

Without a TRUE fix I will really consider to cancel that inefficient Office 365 subscription

You haven't told us what you have tried so far to fix the problem. Until you have done so, nobody here will be able to help. Remember that this is a user-to-user forum, not Microsoft support.

If you want to cancel your subscription, see instructions in the article at https://support.office.com/en-us/article/cancel-office-365-home-office-365-personal-or-office-365-university-d219b5a5-9443-44cf-bcfa-80a052bdd18c.

Thanks Stefan

I din't try anything so far 

It is a fact specific to Office 365

And because I can see other having the same issue I'm here to check if someone knows more about this issue !

As part of troubleshooting, you can start Word in Safe mode and see if that improves the situation. See https://support.office.com/en-us/article/open-office-apps-in-safe-mode-on-a-windows-pc-dedf944a-5f4b-4afb-a453-528af4f7ac72.

By the way, when you say that programs are slow, exactly how slow are they? Here, I'm running the most recent update of Office 365 and I haven't seen any slowness in Word. (Outlook does appear a bit more slow than older versions.)

It is slow in starting up.  When the program gets running it is as fast as can be.  I have focused on the computer itself before coming back to Microsoft office.  

Thanks!

Thanks for the follow-up. Doug mentioned that programs start in 2 seconds on his installation. How much longer is it on your installation?

Here, Outlook sometimes get stuck on the splash screen so that I have to click the X to close it. The next time it starts fine. Word does not misbehave like that at all, in my experience.

That is certainly slow.

The first thing to try would be starting Word in Safe mode. If that makes a difference, the problem might be related to (a) a damaged Normal template, (b) poorly designed COM or Startup add-ins, or (c) damaged registry entries in Word. (a) and (b) are the most likely culprits and they are both discussed in the article at https://support.microsoft.com/en-us/kb/921541.
