problem outlook sending empty mail

[dawood.shaikh]

After recent Microsoft updates (Version 2310, 2311), customers reported an intermittent issue that when sending a message from ZCO, it is delivered as a blank message to the recipient. The issue is not consistently reproducible and there are no definite steps to reproduce it. There have been no changes in the ZCO product that caused the issue, as we found this issue is not seen on Outlook versions not having the latest Microsoft patch. Our engineering team has also submitted a post on Microsoft forums asking for their immediate attention. We are also analyzing the issue and trying to find a root cause and feasible solution for the ZCO product. We will update as soon as we have an ETA on the fix.

For the customers facing the issue, the workaround is to downgrade their Outlook to the previous version.

Unfortunaltely, a customer tell us he has the same pb of blank mail after upgrade to ZCO 9.0.0.1939

We will follow this closely and see if other customers report the same problem.
It would be very annoying after asking them all to update...

We can confirm that version 9.0.0.1939 does NOT RESOLVE THE PROBLEM.
Many customers still call us after being disappointed by lost emails...
A new ticket has been opened on Zimbra support, while waiting to give them more logs when the situation arises with a client.

Could it be an issue with non US-English Outlook?

We can confirm this - Zimbra 10.0.6_GA_4585 with the latest connector and the problems are still present with various users - Outlook 2021 32bit German is in use.

Are there any updates on this case ?

We have some customer who gets really nuts because of it, and some already ask to switch to Office 365.

Hello!

We have this problem and nothing solves it. Update the Zimbra connector and don't even uncheck the autosave option.
Has anyone had any progress? since downgrading machines to a previous version of outlook is quite complicated.
