Hi,

I'm having the following issue with clients since we've started upgrading to exchange 2016 and outlook 2016.
This is whats happening. everything is working fine and for some reason you close down outlook, when you start it again you will get the attached error.

 "Cannot start microsoft outlook. Cannot open the outlook window. the set of folders cannot be opened. microsoft exchange is not available. either there are network problems or the exchange server is down for maintenance.

When you wait 20 to 25 min you can start it up fine again.

I came across a microsoft workaround that tells you to recycle the autodiscoverpool in your iis every few minutes. i'v set this up but besides creating a whole different list of errors and problems this does not seem to resolve the above issue.

I'v updated the clients and updated the exchange server 2016 to CU2.

Any idea's would be most welcome at this point.

Thanks alot

Not something I have seen myself.
The usual of something like that though is third party interference. AV software scanning something it shouldn't be, or a plugin within Outlook.

Go through the server's application logs for anything suspicious. If AV is installed on the server, ensure it has the correct exclusions in it.

Hi Simon,

We Checked the plugins and tested it without any plugins, no changes.
also we uninstalled the AV software completely but no difference there either.

The problem has spread though, got 3 other customers with the same issue, and our own server is having this problem also now.

All recently installed Echange 2016 servers.
Thats the one thing i'm absolutely sure about, its all connected to that exchange 2016 server.

We are now testing with the RPC session timeout settings and MAPI settings, hoping that will do something.

will keep you posted.

Little Update:

When someone is locked out of there outlook and we run a IISRESET on the exchange server there able to get back in again.
when they close outlook again after that the problem is right back though.

but look like IISRESET does seem to somehow reset the timer.
Can't really schedule this to reset every few minutes though as this disconnects everyone's outlook as well.

Another Update:

We just disabled MAPI connections on a PC trough a regkey setting. (So we are forcing the workstation to connect to the exchange server via RPC)

What do you know, it works. when forced to connect over RPC there are no problems. (Not a long term solution though as the RPC connections are noticeably slower then the MAPI connections.
Ok, so now we know are the problem lies. its the MAPI connector on the exchange server side thats messing up.

How to fix this.?.?

Will keep you posted.

Hi Martin,

Can you check the connect status on one of the accounts that has this issue. I am interested in the Protocol.

to do this hold down CTRL key and right click on the Outlook icon in the system tray then click connection status.

Hi Dave,

Here are 2 screenshots, one from a computer without registry alteration so going over MAPI, and one with the RPC connection forced trough Registry fix.

Okay, can you open Exchange powershell and run this

Get-OrganizationConfig | fl *mapi*

This will tell us if mapi is enabled, i don't think it is by default.

When it is enabled this should force all Outlook clients to connect using mapi over http.
Any Outlook clients that are running will be prompted to restart Outlook

Hi Dave,

The command gave back that the Mapi is enabled. But we still have the isues when you close a outlook. Domain pc or non domain pc. Cached mode on or off doesn't matter.
When we close it it takes ~20min before the person can reopen outlook unless i do a issreset.

As you have stated that you think the issue is mapi I would suggest disabling mapi therefore forcing all outlook clients over rpc

Run this in Exchange power she'll

Set-OrganizationConfig -MapiHttpEnabled $false

It does, as you say the same thing but without needing to modify the registry on every client

Just a small update:
I have disabled the mapi and so far all the issues are gone. For people reading this later.
run a iisreset.
run the command.
(then ran another 1 just to be safe and make sure everyone has fresh connections)
