Hello Experts,

I need your help to build a PowerShell Script to resolve a production issue. Basically, there are 10 users that had been granted with full access over 50 shared and resource mailboxes, and every time they launch outlook, all the 50 mailboxes are automatically mounted because the auto mapping feature.

the script should perform following:

Given a user name or email alias as input, the script should return or display all shared/resource mailbox where that user is granted with full access and auto mapping is true. I mean it should list all these shared mailboxes where the user is owner  and export to a CSV file.

Once the information above is exported, we need to remove the account from all shared/resource mailboxes where it was granted access to and then  add it back with auto-mapped = off settings.

I was thinking in something like below:

$allMailboxes = Get-Mailbox -ResultSize unlimited

foreach($mailbox in $allmailboxes){Get-MailboxPermission sharedmailbox |where {$_.AccessRights -eq "FullAccess" -and $_.IsInherited -eq $false}}

$FixAutoMapping = Get-MailboxPermission sharedmailbox |where {$_.AccessRights -eq "FullAccess" -and $_.IsInherited -eq $false}
$FixAutoMapping | Remove-MailboxPermission
$FixAutoMapping | ForEach {Add-MailboxPermission -Identity $_.Identity -User $_.User -AccessRights:FullAccess -AutoMapping $false}

The issue we are facing is that is not returning proper values. I need to be able to run a query against all …

Hi all,

We encounter issues regarding Dynamics365 (Version 9.x) and Office2013 with Outlook Web App and S/Mime signed emails.
The outlook web app for Dynamics365 is not visible in Outlook if we are clicking on a signed email.
If you click on a normal email without any signature, the Dynamics365 outlook web app will be showed correctly.

Is there any incompatibility or any additional configuration required?

Many Thanks
Office 2016 freezing Outlook, Word, and Excel freezing up
Outlook archives.  I have a user that had over 76,000 items in one folder in his inbox., needless to say he had performance issues, where Outlook would hang, other folders had over 45,000.
I got him to finally archive. Local archives (tried to keep them small are in the 7-12,000 range.  I rather he does not keep the archives open but rather opens them should he need to search for something from a prior year etc.

My question is, are the content of PST files indexed if they are NOT attached to Outlook, so if he opened one, might it take excessively long to find what he is searching for?
Dear All

              I have recently Migrated on premise exchange mailbox to O365 but I found it can not connect to outlook on premise window 7 computer, and I found out my exchange ssl certificate only contains "mail.domain.com" but not "autodiscover.domain" , what I need is a Muti SAN certificate, but I just created below SRV record in public DNS server instead of buying a Muti SAN certificate, after that I tested but it still can not connect in outlook for the migrated mailbox, see bottom screenshot,  I receive the popup saying that it redirecting to https://mail.domain.hk/autodiscover.autodiscover.xml , what I can do in order to get this resolve ? any help would be appreciated

Service: _autodiscover
Protocol: _tcp
Port Number: 443
Host: mail.domain.com


I have opened Microsoft Word 2016 multiple times over past months using "Run as administrator" and clicked "Remove" on the following add-ins.

Add-ins Removed from Word
Despite manually removing the add-ins multiple times, I am constantly being frustrated by those add-ins re-installing themselves whenever Microsoft Office receives an update from Microsoft. I've noted this happen several times now and can't seem to find a way to prevent it from happening.

The same behaviour occurs in both Excel and Outlook - removed add-ins reinstall and reactivate themselves. Unsure of other Office applications as I rarely use more than the three discussed here.

Other add-ins in Outlook include WinZip Courier, Avast Antivirus Pluggin and others. There is no pattern relating to the add-ins themselves. If an add-in is available, upon recieving an update for Office 365, everything is re-installed after the update and re-activated.

Does anyone know how to stop this annoying behaviour once and for all? What am I missing?

Regards, Andrew
Interesting problem:  In Outlook 365 the button in the search functionality are not working, for instance, the "From" and "Has Attachments" buttons are greyed out.
OS: Windows 10, I believe version 1803
What was done: Execute Windows Update with updates to other Microsoft products.
2. A sfc  /scannow was executed  since I could not open the  Mail icon in control panel to create a new Outlook profile.

What I should have done: login to the system as myself and see if it happens under my account.
Notes:  The user can still perform searches in Outlook, I was told that rebuilding the i Outlook index did not help. I even notice an entry in Outlook that said Upgrade search.
I was going to perform an online  repair of Office 365 Pro Plus,  but that could take about up to one hour.
I did not check to see what was installed on the system recently, before the problem first happened, but I did collect the application, system and security event viewer logs.
Next steps is uninstall Office 365 with the Microsoft uninstall /re-install tool then re-install office from office.com
The other  thing, I can try is to start Outlook in safe mode, and see if the problem re-occurs and if it does, then I will have to remove the add-ins and add them back one at a time
I suspect that a recent Windows Update caused the problem so I may have to remove them at a time.
I was thinking of a DCOM permission related to the search functionality in Outlook.

What I am looking for help with is what …

Sporadic problem with Outlook client (Outlook 2016 client using O365)

More and more users (and myself) are noticing stripped images in Outlook.  Specifically it says "The Linked image cannot be displayed. The file may have been moved, renamed, or deleted. Verify that the link points to the correct file and location."   The internet is pointing me everywhere but the kitchen sink.  I am inclined to think it is NOT Temporary Internet files since it seems to be happening on a lot of different machines for different users; one of which has only been here two weeks so it is doubtful his internet cache would need clearing so soon.  I have seen articles that anti-malware software could be doing it (specifically Malwarebytes) but I am not sure about that either.  There is also a thought that our web based spam filter could be doing it as well (SpamTitan) It DOES seem to be only Windows 10 machines so far though as far as I know but that is not verified just yet...nor  have I heard it happening with our Macs either; either of which if that is the case; would eliminate spamtitan.  Does anyone have any credible suggestions for what could be at issue that would affect multiple users/clients across multiple sites?  Any thoughts would be greatly appreciated.

Hi All,

we have a client that uses ESET anti virus and recently received their Cyber Essentials Plus.  since then one user who uses Windows 10 is having trouble with outlook (2016).  it just says Disconnected at the bottom.  if we do get it working, it will only work until the PC is shutdown, then when they come in the next day its back to being disconnected.  i also tried to create a new outlook profile but it just says "an encryption connection to your mail server is not available".   their mail runs on office 365 and i have been able to set his mail up successfully on my machine which is located out of their office.  it seems to be only for this one windows 10 machine, other machines are windows 7 and work fine.

Any Suggestions would be appreciated.
I am looking assistance especially from Exchange Experts.I am experiencing a strange issue on Certain Mailbox DB in Exchange 2010  Hybrid environment with O365.    number of colleagues within DB O-U  are unable to search email within outlook 2016,2013 , it shows only last 12 months email and does not show any email  over year time .for example if User  Oscar search an email in outlook it only shows result upto last 12 month and  unable to search email befond 2018.  I have nearly 20  colleagues effect and falls under the same mailbox DB.

is there any powershell command or script to fix this issue ,

We are looking for a solution to automatically copy emails from a user's deleted item folder in Outlook 2016 (no access to Exchange, the solution must be local) into a SharePoint 2016 library while maintaining the associated metadata and mapping the email's metadata in the document properties columns. Currently, in order to perform this operation, we have an admin assistant manually dragging all emails from the deleted items into the Harmon.ie Outlook add-in every month, being a manual operation, errors can easily happen, since those emails have archival and business value to our organization we wish to eliminate human error. While Harmon.ie have an automatic email upload option, it rely on Outlook's rules which do not apply to the deleted items folder. Ideally the solution would integrate with Outlook and would either be able to simply move all deleted items into another folder based on a schedule where this second folder would be handled by Harmon.ie to bring them into the SharePoint library or automatically move them directly in SharePoint and map the metadata on the items.

Thank you,
I have a user who has editor permissions to another user calendar in Outlook 2010.  She used to be able to add entries fine but now whenever she enters an appointment it deletes itself after about 10 seconds?!

Other users with permission to add to this calendar can add entries without any issues?  I have checked the permissions and the problematic user has editor rights which should enable her to add items without restrictions?
I hve a user (of course the CEO) who has 75gb of mail in his office 365 mailbox, of course he needs every single email he has ever received (please note the sarcasm). He complain his outlook is slow, and of course can be without them. They are in folders outside of the inbox. I need suggestion to speed his outlook up, it is slow to respond and "goes to a faded screen" the comes back on after a few seconds. I will take anything even any kind of 3rd party.

As you can assume archiving and deleting isn't an option.
There was no noticeable issue with my first wave of users, but I am now seeing a couple of lag-related issues in outlook.

All our outlook clients are on-prem, nobody accesses outlook externally. Our mailbox environment is pretty lean--we have 80 users but the total size of the MBDB is about 45GB

All user, shared, and resource Mailboxes are on EX16. Internal DNS and firewall is pointed at EX16. Our EX10 server is still in service but the only thing it is doing at this point is hosting the Public Folders until I run the migration process for that.

Issue one, that I'm less concerned about, is Outlook takes about five more seconds to load on average for a user who just has their own mailbox or nothing else. Before moving the mailbox, it was like five seconds or so to load for an average user, after migrating the mailbox to EX16 it is more like 10-15 seconds. It can be anywhere from 30-60 seconds if the user has full access to other mailboxes or resources. When Outlook loads, the lag occurs when the splash screen shows "loading profile," prior to the outlook icon appearing in the tray and prior to loading add-ins etc.

Thing two, I notice that dealing with additional mailboxes that I have full access to, there is a lag of up to 10 seconds if I navigate to a folder under the additional mailbox if I have not been in it for an extended period. Both my mailbox and the additional mailbox are on the EX16 server. When the mailboxeswere on EX10, the browsing was always …

Using Exchange 2013 and Outlook 2016

Recently i have found that all of my users are having this issue.  the OAB wont update and also Outlook crashes occasionally when sending emails.  emails send normally most of the time but sometimes it crashes and you have to retype the email.  by crash i mean goes white and you get the not responding message and you have to exit as it never come back.  

I am finding that outlook is creating a .tmp filin the appdata>local>Microsoft>Outlook folder every time you open outlook.  the exisiting OAB does not update at all and if you remove the OAB and try to download again it does not create a new one.  outlook itself shows 'Updating Address Book' in the status bar and this never goes away.  if you try to use the client to update the address book it either fails or crashes.

other than this outlook works fine.  i have over 50 PC's all having the same issue.  All runnign office 2016 and windows 10.  updates have been appllied to all of them and are running latest office and windows.  i have tried all this using general user and domain admin and get the same result so im pretty sure its not permissions.  i have used exchange PS to run Get-AddressList | update-AddressList and Get-OfflineAddressBook | Update-OfflineAddressBook  these comeplete but its made no difference.

the only thing i can see in the event log as an ESENT error for cortana:
Log Name:      Application
Source:        ESENT
Date:          17/01/2019 10:09:18

I have outlook 365 and am tyring to add a CNAME to my DNS to be used with Outlook 365 for DMARC and DKIM but I don't know what to put as the ALIAS.

My DNS is managed by Network Solutions, but they said that I need to know what ALIAS is to be used with Outlook 365.

Does anyone know what this could be.
I have a weird situation that has recently popped up with Outlook 2010 connecting to an Exchange 2016 Server that is offsite and in a different AD domain.  The Exchange Server is hosted by a parent company and all of my users have separate accounts in that domain for Exchange use only.  I know that isn't ideal but I have to work with it.  Anyway, this problem seems to have popped up after we enabled caching mode on the Outlook 2010 clients.  They had previously been directly connected for years but people have been complaining about slowness so our answer was to use cached mode.  

What is happening is this:
The user will start Outlook 2010 and be shown the cached contents of their mailbox.  The Exchange server will try connecting and then show a NEED PASSWORD button where it would normally show Connected to: Microsoft Exchange.  You can click the button all day long and nothing will pop up letting you put in credentials.  If I delete the Outlook profile and recreate it using the Outlook 2010 wizard, it won't even resolve the name to a mailbox after it knows what it is looking for in autodiscover.  I can have them log into OWA just fine but Outlook 2010 won't find the server or mailbox at all.  The only way I can recover from this is to delete the user's Windows 7 profile and start them with a fresh one.  Only then will it resolve the name on the server and connect the mailbox after supplying the proper credentials in that domain.  It may work for a day or two or …
