Microsoft includes office 365 in the image of win10 pro.  After uninstalling office 365, rebooting and then installing office 2016 H&B after about the 5th reboot, Outlook changed back to Outlook 365. That's right AFTER it was uninstalled, and AFTER several reboots! We have seen this before, as has MS. I had project 2010 installed as well.  I used the office uninstall tool from MS, which removed office, and only part of project (That is the problem), I need to get rid of MS Project still showing under apps and features. I can't repair/uninstall it, I get an error every time.  I only need to get rid of the entry because it was partially uninstalled and will not allow me to reinstall it!
Does anyone know how to clean this entry up in windows 10?

Thanks guys!

We currently have a distribution list for capital goods. We would like to have an additional address that could be used externally for our dealer/counterparties . Could we please have "cap.markets@domain.com" as a distribution list for external parties to use (note we would not want this to be internal as it would be confused with other distribution lists)
Hi there,

We're in the process of migrating from Exchange 2010 to Exchange 2016 (both on prem). The new server is up and running, with inbound and outbound SMTP routing fine. That said, we've just run into a problem with the first real mailbox move (I say real, as we did create an test mailbox on the 2010 box which we then moved across with out any problems). We're wondering if the mailbox has not moved correctly, or perhaps we have an issue with the autodiscover / virtual-directory configurations (we run split DNS, so the internal / external URLS are the same, and have been set accordingly. The URLS point to the new Exchange 2016 server).  The problem manifests itself as follows:

  1. When the user logs in via OWA, it seems to redirect him to the mailbox on the old server (which by all accounts, appears to be where the email is still being delivered).
  2. When he opens Outlook, the client times out and eventually returns the error message - "Log onto Exchange Active Sync (EAS). Server can not be found". We are running Outlook 2016 client as part of our Office 365 subscription.

If I open Outlook 2016 using the test mailbox account, it seems to connect fine. We've tried re-creating the users Outlook profile as well. We're kind of running out of ideas, so would really appreciate any suggestions.

Many thanks,

a user  is requesting help for a capability to "poll" external parties to facilitate scheduling efforts.  To my knowledge, Outlook polling only looks to be able to handle a single yes or no rather than yes or no to a list of dates .

Every once in awhile, User A  askes me to schedule a conference callwith some OUTSIDE TEAM  members.   I usually send out an email like this:

USER A would like like to schedule another conference call.  Please let me know whichdates/times are agreeable with your schedule.  

July 26 9-10; 10-11; 11-12

July 27 9-10; 10-11; 11-12

Someone suggested that I use Doodle.  When I went andlooked at Doodle on Google, it was something that while free you had to download stuff and I know IT does not want us downloading stuff willy,nilly.

I'd like to be able click a QAT shortcut to run a macro which opens the current Outlook message in editable mode. And inserts the text "[Edited]" so I can see it has been.

I had a solution for Outllok 2013  Outlook Emails Opening As Editable which no longer works. Sue Mosher's solution at http://www.outlookcode.com/threads.aspx?forumid=3&messageid=31310 also seems kaput (for me).

Any suggestions?
can a delegate user B get the responses to meeting invites sent by the USER A mailbox for which he is delegate

I am attaching 1 document which shows some options, can anybody explain them
we have a client that is currently using gmail for their email services. A single email address.

We have installed a new exchange 2016 server and outlook 2016.

The mail server is running just fine. ie we can send and receive email OK.

The problem we have is with outlook.

When we add the gmail email account to outlook, it works fine. When we try to add the exchange account it fails to add. If we then remove the gmail account, we can add the local exchange account just fine, but when we try to add the gmail account, that too fails.

we seem to be able to have one or the other, but not both.

can anyone advise why we are having problems with this, and what we need to do to get both working?

They will of course be migrating to the exchange account eventually, but currently everything is still running on the old gmail account, so for the short term at least we need access to both.

Any suggestions.

2nd question:
Creating a Shared Calendar.

If I am correct, you can create a Calendar in your Outlook and share it with other People. in this case I wonder when you are not in the company , whether other people will be able to use the calendar, assuming they have also Owner permissions on the Calendar.

I believe even if the Calendar is created on Outlook it should exist in Exchange server, and other people should be able to access it as long as they have permissions.

I  know that you can also create a non-user mailbox and use it as shared mailbox if you want to , and create a calendar in the non-user mailbox and share it.

So what it is the pros and cons of one approach versus another

Thank you
I use Microsoft Outlook 2013 to connect and read my Gmail account. So therefore, I do not have a PST account for outlook because of this connection.

If I wanted to backup my Outlook emails and contacts to a local drive what do I need to do?  

Do I need to create an OST file and back it up to a local drive?

Is this a non issue because the Gmail does all this work for me and therefore I do not need a backup on a local drive.

Where would I look on my "C:" drive to see if I have a backup at this time?
Office 365 client has a message popping up when opening Outlook;
Properties for this data file must be defined prior to use.
A window pops up, to navigate to an outlook file, but if you just close it, another message pops up;
This data file has not been configured,. Select an existing file to configure, or type the name of a new file to create.
Close that & then outlook opens & appears to be running as it should. Going to account properties shows it has the correct data file - what is causing this & do I just need to navigate to that file once & that should 'fix' it?
The search function in the calendar folder returns no items.  The search simply stopped working.  I've rebuilt the indexes, rebuilt the Outlook profile, and even created a new user profile, and yet the calendar search does not work.  The inbox, mail folders, search works fine.  Only the calendar item search doesn't work.  I've been trying to fix this for months, but now need your help, please.
Cannot open encrypted e-mail from and individual.

a c ouple of times i added a drive to my test PC - to make a backup
when accessing the users folder, it asked as Always for permission - granted and all is fine

 - BUT had following problem, when i put the disk back in the Original pc i could not open several programs, or shortcuts
programs did not run as usual, etc, see screenshot
as an example, OUTLOOK opens and shows the mail tekst - but not the attachments ; he can send mail, but not receive
etc; it also reports for all programs : cannot open, or write to files - - so it looks like a file authorisatioon problem
in start - i s ee the proper user though
i have had this with another disk  some months ago, and never found the reason

the system is running 2 OS : win 7 and win 10 in Dual boot - MBR formatted
does this have  something to do with it?  oh yes - there's nothing wrong with the disk either
I am in the middle of an Exchange 2010 > 2016 migration (with Outlook 2010 clients).  The exchange 2016 server is handling all the mail flow and I am starting to migrate some test user databases from Exchange 2010 > 2016.  

The migrations seem to go smoothly, but I have noticed that when a user's mailbox resides on an Exchange 2016 database, when they open Outlook 2010 they are prompted to renter their password.  Once they enter their password, Outlook connects as usual.  This does not happen to users that still have their mailbox residing on an Exchange 2010 database.

When completing the migration I followed a guide stating that I should ensure that NTLM is set as the authentication method for external clients on the EX2016 server (the default is negotiate).  I am not sure of the details, but believe this is something that needs to be done during the migration period to allow the proxy'ing to EX2010.  From what I understand NTLM authentication method  is what is causing the necessity to re-enter the  password when launching Outlook and if I set this to negotiate, the prompt should dissapear and the user will be logged straight into Outlook.

So now that Exchange 2016 is handling the mailflow, but Exchange 2010 still hosts most of the mailboxes, can I safely set this to negotiate?  Will there be any impact on the users that still have their mailbox on EX2010?

Please bear in mind that we do have public folders still residing on Exchange 2010, so I am unsure if this …

Is there a way to export (and import) the colour categories from an Exchange account?   Not the colours themselves, but the actual assignment of them on mailbox items such as emails and calendar entries.

I've recently complete an Exchange 2010 to Office 365 migration and performed all of my usual post-migration tasks such as editing the autocomplete lists, calendar and mailbox sharing, additional aliases, distribution groups etc.  But I have this one user who had about 15 colour categories being used across various entries in his calendar and he wants them brought across.
Dell laptop (Inspiron 14R) will not send/receive email using Outlook 2007 or 2016. Connection to Internet OK (otherwise You will not get this message!). All other Internet transactions OK, problems unique to Outlook. Problem existed for few weeks. Other Win 10 Outlook 2007 PC (on same LAN) OK for send/receive. This EE MSG sent from same Dell laptop (not using Outlook).

Task 'marybeatrice@charter.net - Sending' reported error (0x800CCC61) : 'Your outgoing (SMTP) email server has reported an internal error. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).  The server responded: '
When using Outlook 2016 the to field doesn't populate with suggested users while typing the name for a users who is a member of the global address book. If I then click the to button to search from the address book if there is a match is will populate that user in the background and then bring up the address book.

If I search from the address book directly that works fine without any issues & if I have already sent an email to a user this is autopopulating in a dropdown list.

We are getting the same experience across all of our users.

We are migrating the majority of users' bloated mailboxes and project related public folders to MailManager

Some Partners in the company have up a mailbox of 20GB with 100,000 emails.

Having copied the emails to Mail Manager where they are safely on our file system, we tried to clean up the mailboxes by deleting everything older than 1 Jan 2017 but Outlook hangs and doesn't like deleting 10,000+ emails.

I found here that I could do this on the server


Using the command

Search-Mailbox -Identity <username> -SearchQuery '(Received:2000-01-01..2016-12-31)' -deletecontent

Open in new window

Which worked like a charm. Except it removed contacts as well as emails. Not popular with the partner concerned.

So we are restoring his mailbox from backup, sigh.

Once back to square one we will still need to clear the old emails.

Can anybody suggest how the command can be filtered to delete emails only and leave contacts?
