Microsoft Teams no Camera found

There are a lot of various articles out there on how to try to fix a missing camera in the Microsoft Teams desktop app on Windows 10. 
I found the issue was the laptop had an in place upgrade from windows 7 to 10 and the camera was was installed under the Camera Node in Device Manager. 
To fix the issue I had to uninstall the camera and remove the installed drivers. Once I did that and scanned for hardware changes, the camera reinstalled but under the Imaging Devices node. Relaunched Teams and the camera was now being detected.

NSX Management Service Operation Failed. (Initialization of Admin Registration Service Provider failed. Root Cause: The SSL certificate of the STS service cannot be verified)

The Problem
So I am new to supporting VMware from an infrastructure prospective and do to some departures at our company, our large VMware deployment is now my responsibility. 

A few weeks ago, I updated our expiring Vcenter custom machine certificate using the VMware SSL certificate tool. This Vcenter is still windows but thanks to these two articles, we were able to fix this issue:

Recently replaced our Vcenter custom machine certificate using the SSL cert tool. This Vcenter is still windows but thanks to these two articles, we were able to fix this issue:

Outlook 2010 - Error While Preparing to Send Sharing Message

We recently satarted to see an eror when users try to send a calender sharing invitation to users from their Outlook 2010 client. the error prenented reads as follows "Error While Preparing to Send Sharing Message" Our orginzation at the time of writing this is runing Exchange 2016 CU4 and Outlook 2010 SP2 April 2017 Updates and Outlook is configured to use MAPI over HTTP. the issue looks to be tied to the permissions on the calendar and permisisons being present for users who nolong are with the orginization and their mailboxes have been disabled.
to ressolve this issue review the permission list on the calendar and remove any users who nolonger have a mailbox within Exchange. 
You can as workaround, use Outlook on the Web to share the calendar and that will work just fine

Outlook On The Web Error when Saving Calendar Appearance / Reminders Options

I have been meaning to post this for a while now and well life and work sometimes get in the way of sharing the nuggets of info from my job.
So here is the scenario we were running into:
upon migrating an Exchange 2013 Mailbox to Exchange 2016 CU1 some users when adjusting their calendar appearance or setting the option to send a daily agenda email would get an error when saving their settings. The user would get an error that "There was a problem saving your changes. Please try again." you would then see a correlating error in the event viewer with Event ID: 4999 on the server the user was connected to. After working for several days with support, we found that within the mailbox calendar configuration the weather location bookmark was set to a -1 rather than a 0. This setting is currently only used in the O365 and we are not sure as why when migrating a user this bit gets flipped for some users.
you can see this property value by running a Get-MailboxCalendarConfiguration -Identity |FT ID*,Weather* we found that the only way to reset that value was to use MFC Mapi and delete the IPM.Configuration.OWA.useroptions from the users mailbox.

To find all Mailboxes affected you can run:
Get-Mailbox -Server <ServerName> -ResultSize unlimited | Get-MailboxCalendarConfiguration | Where {$_.WeatherLocationBookmark -ne "0"}| FL Id*,WeatherLocationBookmark

to Resolve:
1. Download the latest version of MFC Mapi
2. Grant yourself Full access to the effected users mailbox (Add-mailboxPermission -Identity -User -AccessRights FullAccess)
3. Ensure the user has MAPI access enabled
4. Open MFC Mapi

a. Click Session > Logon
b. Locate the mailbox on the right hand side and double-click it
c. Right-Click the Root Container and chose Open Associated Contents Table
d. In the new window that opened scroll to the right till you see the Message Class Column
e. Scroll down till you locate the IPM.Configuration.OWA.UserOptions Message
f. Right-Click IPM.Configuration.OWA.useroptions and chose Delete Message
g. In the Delete Item Window click OK
h. Close all MFC windows
5. Verify issue is resolved by running Get-MailboxCalendarConfiguration -Identity <username>  | FT WeatherLocationBookmark

Mailbox Export Request and MapiExceptionUnknownUser: Unable to make connection to the server. (hr=0x80004005, ec=1003)

As I was preparing to export several mailboxes to PST for a Cross Forest Exchange 2010 to 2016 Migration as a part of an acquisition, I ran in to an issue that when I would run a New-MailboxExportRequest and get an error "Couldn't connect to the source mailbox" When running the cmdlet with a -Verbose, would see the error "MapiExceptionUnknownUser: Unable to make connection to the server. (hr=0x80004005, ec=1003)" After going through some troubleshooting steps:
-Verifying MAPI is enabled on the accounts.
-Verifying that the Exchange Trusted SubSystems group had R/W Share Permissions.
-tried a different users.

After nothing fixed my issue, I called support. One troubleshooting step that they had me do that never crossed my mind was to create a new mailbox database. after doing that I moved a user successfully to that database and was able to export it with no issues. upon comparing the mailbox database settings Get-MailboxDatabase -Identity I noticed that the new database did not have a Public folder configured and the other database did but it looked as if someone had deleted it. Using ADSI we removed the Public folder path from the database and were able to export mailboxes without any issues.

Removing Public Folder path from Mailbox Database:
1. Launch ADSI and enter the configuration Node.
2. Navigate to :
Services > Microsoft Exchange > Exchange OrgID > Administrative Groups > Exchange Administrative Groups (FYDIBOHF23SPDLT) > Databases
3. Right-Click the Database with the public folder you want to remove and click Properties
4. From the Attribute Editor tab select the attribute msExchHomePublicMDB
5. Click Edit
6. Copy that value to a text file as a backup. :)
7. Click Clear
8. Click OK
9. Click OK to close the attribute editor
10. Close ADSI Edit

Outlook Opens Minimized

Ran in to this strange issue today. a User was complaining that outlook would start minimized. We were able only able to have it reappear by using task manager to maximize the application. I was able to open Outlook without any issues starting it in safe mode (Outlook.exe /Safe). Upon ruling out that shortcut was not set to start minimized and that no COM add-ins were causing the issue , I did a quick search and found in an MSFT TechNet post from Rob Kubben to remove the Frame registry key located in the [HKEY_CURRENT_USER\Software\Microsoft\Office\\Outlook\Office Explorer].
Upon restarting Outlook it opened maximized and would remember its last window size properly.

Outlook on The Web Prompting for Credentials from my Web Proxy

Recently we begain moved about our users to our new Exchange 2016 infrastructure. We begain to get a few calls from some users that they were being prompted for credentials whenever they would open an email in Outlook on The Web that contained external embedded content. In our eviroment a lot of our generic workstations and if you want to go out to the internet, you must provide you AD username and password. upon further digging, we found that Outlook on the Web will send multiple GET requests prior to being prompted for credentials. The only way to work around this issue is to open a website and go to site such as cnn.com to get authenticated. Once authenticated you will be able to open an email with embedded content.
