Searching Outlook 2016 using MAPI returns errors and is also very slow (SM 7579)

Testing MAPI with Outlook 2016 in SM 7579.

When I do a search in a big folder, Outlook returns me this advice:

My settings are already configured to use CACHE mode and ALL mantained offline

It is also very slow compared to the same search done on Exchange account (I did the account migration and the content is exactly the same)

PLEASE NOTE: this is a very serious problem that affects the possibility of giving service to customers, because they would DEFINITELY start opening assistance tickets and complaining ...

Gabriele, you are not alone, we have encountered it too. We see it generating very high CPU on the server side. This is one of the reasons we cannot deploy MAPI to users.

CPU utilization is a problem.

Right now as I am typing this we have 31 connections.

1 stmp, 20 imap, 1 pop, 6EAS and 3 MAPI.

Server is running at 90+% cpu, build is 7573

We have only migrated a few domains and stopped migrating due to the issue.

Im sure it will be sorted out soon.

Mail server stopped responding during the night and found a 98gb mapi log file this morning.

Hey Gabriele, can you open up a support ticket for this issue? We'll probably need to get a Fiddler trace at the very least and maybe some additional information.

We know if you only download part of your mailbox into Outlook, then do a search, and then tell it to find more on the server it could take a while. We have future plans to look into that issue.

Hi Larry, I think you haven't read what I wrote...

I know that partially syncronized mailboxes have problems, BUT my settings are already configured to use CACHE mode and ALL mantained offline AND Outlook is FULLY SYNCRONIZED

And I DON'T tell outlook to find more on server...
