This can be a snaggy error to fix. I have seen this error for years with Microsoft Exchange. Lately the fix for me has been to delete the 16,454 KB size file in the app data folder.
Usually I back up any file I delete but this one is not really a data file that works with the OST, when you set up new Outlook profile it just makes it. And this can get snagged up I believe. If you delete it, then try reopening Outlook it might work. If not make a new profile (don’t delete the old one), set Outlook to open new profile. See if it performs better.
I also had to run 365 updates on my last client to get it working.
If not, then you might have other issues such as a VPN problem, Antivirus or Firewall.

Need help getting Gmail to sync properly with Outlook? I help clients every day with Gmail and Google Workspace accounts that are not syncing correctly with Outlook Classic, New Outlook, phones, tablets, or multiple computers.
Whether your email is missing, folders are not updating, contacts and calendars are not syncing, or Outlook is running painfully slow, I can help figure out what is actually causing the issue. Sometimes it is an Outlook profile problem, a Gmail IMAP setting, Google Workspace Sync (GWSMO), corrupted OST/PST files, security settings, MFA, antivirus conflicts, or just years of old Outlook setup problems stacking on top of each other.
I also help with:
A lot of people think syncing issues are “just Outlook being Outlook,” but there is usually a technical reason behind it. I specialize in figuring out the messy stuff and simplifying it for business owners and everyday users who just need their email working again.

New Outlook is still new to a lot of people and while it’s fast…it can still be sluggish. Below is a list of things I look at when I help clients.
I go through most of these during the onboarding of our first appointment and can figure out the problem quickly. Then we move on to solutions. Solutions may take time to repair, or can be moved to a project (migrate email to Exchange) or repair with other options. All options are your choice. If you need help with Outlook slow to sync, feel free to use the form at the bottom of this page and contact me.
