Outlook for Mac - Version 16.99 (25071321) - No Address Book

Testing 16.99.1 now. Good thing is they might have fixed the S/MIME issues that were also occurring with the solution. There is an issue with if you have clear txt disabled, body of email wasn't showing.  Also, if there was a large body in the email, and signing or encryption was happening, also broken. 

Address Book seems ok in 16.99.1 as is there doesn't seem to be a memory leak like there was before (haven't beach balled of death yet). More users testing now. 

16.99.1 was released yesterday https://learn.microsoft.com/en-us/officeupdates/release-notes-office-for-mac

The release notes don't really match the problems mentioned here. Has anyone been able to test it yet?

Same issues here.

No address book or autocomplete when typing email addresses. Can receive emails fine, but sent emails get stuck in outbox and app crashes. 

Disastrous  release.

Build 16.100 in the beta channel doesn't have this issue. So if people can't wait they can change to beta channel under advanced settings in the Microsoft Autoupdater (remember to deselect auto update).

Couple of ours users have the same issue. 
https://office-reset.com/ fixes it for the one who tried it. 

Same here

Same issue. Almost feel like someone didn't test this thing properly.

Same here on the address book issue. Ideas?

Also having the same issue since I did the update. No suggestions when sending mail and very fast memory outage/leak (requiring >80GB RAM...). (Sending calender invites it still works with suggestions)

I played around with enabling and disabling the co-pilot and think that the co-pilot could be the root cause. 
Still disabling and enabling did not solve the issue. :( 

microsoft Please fix - this makes Outlook unusable!

We managed to roll back using JAMF + Self-Service+ however, this morning inside the app it's trying to again update. 

Can everyone please put in a support ticket to MS about this who is affected. 16.99 is a poor release it would seem.
