To-Do list not showing up in outlook 2010/2007

I was faced with an issue at a client where after the migration of a mailbox from exchange 2003 to exchange 2010 the user can no longer see the To-Do list in Exchange Online mode, it would work for Cached mode though.

In outlook 2010 it would show

in outlook 2007 it would show : Could not display folder.

Looking at the move request log I could see errors with SearchFolders, now the problem here is that corrupted items were ignored upon creating the move request.

Luckily we have a tool from Microsoft called MFCMAPI. this tool uses Microsoft’s published APIs to provide access to MAPI stores through a graphical user interface

Now in order to fix this Specific To-do issue, we can use MFCMAPI to delete the To-Do Search folder from under the Root menu as they seem corrupt, which forces outlook to recreate it.

So download MFCMAPI from here 

Open it up and choose Session then Log on and display store table then Double click you mailbox

Then Right click and Force Delete The TO-DO Search under the ROOT.

Open up the affected user’s outlook and it will display the to do list .

Cannot Sign in because the server is temporary unavailable

Today I have faced an issue with OCS 2007 R2 remote access not working and the client returns “Cannot Sign in because the server is temporary unavailable. If the problem persists, Contact your systems administrator”

Well I know this happens because of a problem with ports configured on the Edge.

Running a SIPSTACK trace on the Edge showed the following

Well as you see the listening port is 5061. Well that’s wrong because it should work on 443.

After double checking that the External Access port on the edge is set to 443, I went to the client and changed the External URL to server.domain.com:443, and guess what ? the client surely signed in.

So whether you are running manual or automatic login make sure you specify the port in the Server Address or in the SRV record and set it to 443.
