Outlook 2019 hangs on 'processing...' -- why and how to fix??

Question

Outlook 2019 hangs on 'processing...' -- why and how to fix??

tommls 1

We have Citrix servers running on Win2k16 Server.
After migrating mailboxes to Exchange Online, Outlook 2019 often takes a long time on 'Processing...'.
What is Outlook doing here??
Why does it take so long??
How do we fix this??
I know that one standard fix is to recreate the Outlook profile but this mainly shortens the time for 'Processing...'
Thank you, Tom

Hi @tommls ,

Welcome to our forum!

What specific operations have you done before the "processing" issue occurred?
And does this issue occur with some specific users or all the users in your organization?

To further confirm whether the problem is related to your outlook client, please log in to web mail and check if everything is ok when you do the same operations.

If the issue only occurs on the Outlook client, first of all, considering the impact of the current Outlook version not updated, what's the version of your Outlook 2019? (File > Office Account > About Outlook). Please make sure you have upgraded your Outlook to the latest version.

In addition, I noticed that you have tried to recreate a profile, as I know, there are a number of possible reasons for Outlook to behave this way. For example, some third-party add ins and damaged Office programs may lead to such a situation. Please follow the potential solutions in order from quickest to most time consuming in this article:
Outlook not responding, stuck at "Processing," stopped working, or freezes

Hope the above help! If it's not your case, please provide more information about your issue for our better research.

Hello, thank you for your reply.
Everything in your reply has been done already.
Office 2019 auto-updates on its regular monthly schedule.
Version is 1808, build 10383.20027
These are all Citrix servers running Office 2019.
I haven't had any feedback on starting Office in safe mode though.
Webmail works fine, this is how we know it's the Outlook client, plus it's quite obvious when one sees a 'Processing...' message sitting there for 15-20 minutes.
All the steps in the website link have been followed: no dialog, no long processes other than 'Processing...' (WHAT is it processing??), we use online mode, not cached exchange.
Thank you, Tom

Hi @tommls ,

Thanks for your reply!

Do you mean the issue occurs when you started Outlook 2019, as shown in the below image?

And does this issue occur with some specific users or all the users in your organization?

Considering that you have done a lot of troubleshooting, but have got nothing, it's suggested that you could use Microsoft Support and Recovery Assistant to running tests to figure out what's wrong and offers the best solution for the identified problem.
