I just upgraded our server and for the time beeing everything seems to run smooth.

Calendar is working again with multiple MAPI accounts and I havent run into issues yet.

I have performed a handful of upgrades to version 8776 and the only issue I have seen is that after the upgrade certain users were finding Calendar Items in their Deleted Items folder, but the items were still on the calendar. In other words, nothing was actually gone.

I opened a ticket with SmarterTools and they had their dev team look into it.

They said that the observed behavior seems to be a result of changes made by SmarterMail, which are outside their direct control. To support shared folders and new WebDAV features, SmarterMail modified its WebDAV URL format and implemented redirect logic to guide clients to these new URLs. However, this redirection is causing CalDav Synchronizer to move previously downloaded items to the Deleted Items folder in Outlook, which then syncs back to the server. Despite this, a comparison of the Deleted Items folder and the calendar post-sync indicates that no data is being lost in the process.

They also said that it shouldn't happen after the first time.

Other than that, I have not seen any issues.

Try shared ressources like meeting rooms and calendars. And remember to add more than one MAPI account to the user profile. Then they dissappear.

Fixed in 8790.

We upgraded to 8790 yesterday, for now so far so good,

Fingers crossed!

The integration we have with the Hosting Controller panel seems to no longer work. We are waiting for a response from the HC provider

Hello guys, has anyone had problems with the installation of this version?

No problems with IIS?

Thanks 😉 

Nothing. Everything went smooth as a newly shaved face.

HAHAHA
