Gmail workspace and new Outlook sync problems

Hi there,

We are a hybrid Office 365 (desktop apps, intune, defender) and Google workspace (emails, files, calling).  we have been using Google outlook (GWSMO) for years and it has always been problematic.  late in 2024 we were happy that classic outlook can connect to gmail using oauth2 natively without using the addin, but calendar synch and contacts synch did not exist.

Earlier this year we were happy that the new outlook has solved this problem and started to migrate our users to the new outlook from may 2025.  Really happy about that. 

Our outlook version currently is:

Microsoft Outlook Version: 1.2025.806.300 (Production)
Client Version: 20250822005.29
WebView2 Version: 139.0.3405.125

What we have been noticing recently is that some users are getting delayed emails that can be a couple of hours.  

We have also noticed that when toggling offline mode to off (or on) they are getting delivery errors saying it cannot be delivered.  after a few attempts it goes through but a draft copy stays in the outbox. 

We have seen a similar issue in a forum about delayed email here and we will try the options given as well doing the obvious by pressing the sync button:

what I would like to do is see if we can get the logs from outlook for connections. Does anyone know where that is stored?
