Outlook crashes when opening Address Book

Denis Repp 21 Reputation points

Outlook 2019- fully updated

On-premise Office - this is NOT Office 365

Windows 10 - fully updated

Outlook works normally until I try to access the Address Book. Then it crashes, will not recover.

Cached mode or non-cached mode makes no difference; crashes either way.

Deleted local mail profile, created new one - no effect. Still crashes.

This problem happens on multiple computers, and also in a Citrix desktop environment. So it appears to be a problem with the mailbox, not with a particular computer. What is the fix for this?

According to other searches, this problem has been around for at least six years. How long does it take to fix things?

Any usable help would be appreciated.
