I have a client site running our Windows desktop software on a number of computers with 64 bit Office 365.
On most of their computers, our software is able to send email via Outlook.
However, two of their computers were upgraded to 365 last year (by their IT technician, not us), and both fail when they attempt to send email from our software.
Outlook works fine on its own, and so does our software - on both of these computers. But these two both can't send email from our software. (The other computers, which send email fine, are running exactly the same version of our software.)
When sending email, our software first checks for the existence of "Outlook.Application" or "Outlook.Application.*" keys in the Windows Registry to determine whether Outlook is installed. If not found, our program logic assumes that Outlook isn't installed, and attempts to use MAPI instead to send mail through another email client like Thunderbird (or through Outlook using MAPI). However, these computers both then crashed, because MAPI doesn't work on 64bit computers.
When I investigated these two problem computers, I found that they both had no "Outlook.Application" or "Outlook.Application.16" keys anywhere in their Windows Registry. I have never encountered this before. How and why would Office 365 install without creating these Registry entries? (I had just installed Office 365 on two computers here in my office, and they both had these keys and worked perfectly. And we have never encountered this before, at any of our other user sites.)
I discussed this with their IT technician. He did a complete uninstall of Office 365, and installed them from scratch, using the "on-line" install (that I had used on my computers - I sent him the URL to be sure). However, after this they were still unable to send email. When I investigated, I found that the Registry keys were still missing.
Their IT technician then asked me to export all the "Outlook.Application" and "Outlook.Application.16" keys in "Computer\HKEY_CLASSES_ROOT" and send them to him. He imported these on both those computers, but it did not fix the problem.
However, because the keys now existed, our software then attempted to send email directly through Outlook, using OLE. However it crashed on the line where it tried to create an Outlook Application Object:
loApp = CreateObject("Outlook.Application.16")
I built a special version with some extra test code in it. After failing to run the above line, it tried to run a line:
loApp = CreateObject("Outlook.Application")
This also failed - presumably because some Outlook application components have not been installed.
I did some fairly extensive Google searches for posts that might identify a solution, but found nothing that seemed to fit. A couple of posts suggested running an Office "Repair" from the installation tool.
I mentioned this to their technician, and he did this. Interestingly, when I then checked (using RegEdit), it had created a lot more "Outlook.Application" and "Outlook.Application.16" Registry keys. But our software still fails on both the "CreateObject" lines in that test version, and single "CreateObject" line in the normal version.
Both their technician and I are completely mystified (and now out of our depth in the Microsoft black arts of Office 365 installation and Windows).
Has anyone encountered this scenario before, and / or can suggest where we might go from here?
OK, the original post was getting a bit long, and I didn't want to clutter it with too much information. So here is some further info:
In answer to Eugene's questions:
Using RegEdit, I searched the entire Registry - for one of the
computers that didn't work, and one that did (plus my own here,
which also worked fine).
Their technician installed the latest 64 bit 365. If I understand
correctly, the initial install was done from an ISO file. When that
didn't work, he tried again using the "on line" install (which I had
successfully used here). He used the "on line" install again for the "repair". I don't have current build numbers, but could obtain these later in the week if relevant. But they should be up-to-date.
No we can't reproduce the problem ourselves in-house, and have never
seen it before at any other client site.
The site is running the same antivirus software on all computers (those
that work, and those that don't). So I suspect that this won't be
the cause.
Registry keys that match perfectly on those two computers are:

Something that may be significant:
The Windows Registry on the computer that does not work has four extra keys (that are not in the computer that does work):
Computer\HKEY_CLASSES_ROOT\PackagedCom\ProgIdIndex\Outlook.Application
Computer\HKEY_CLASSES_ROOT\PackagedCom\ProgIdIndex\Outlook.Application\Microsoft.Office.Desktop.Outlook_16051.12325.20298.0_x86__8wekyb3d8bbwe
Computer\HKEY_CLASSES_ROOT\PackagedCom\ProgIdIndex\Outlook.Application.16
Computer\HKEY_CLASSES_ROOT\PackagedCom\ProgIdIndex\Outlook.Application.16\Microsoft.Office.Desktop.Outlook_16051.12325.20298.0_x86__8wekyb3d8bbwe
That computer (which doesn't work) also has a folder C:\ProgramData\Packages\Microsoft.Office.Desktop.Outlook_8wekyb3d8bbwe\ with 3 subfolders in it (with system generated names):
The first (created in 2019) has a subfolder "\SystemAppData" which is
empty.
The other two (both with same date/time in early 2020) are completely
empty (i.e. have no SystemAppData subfolder)
I wonder whether these keys may somehow be causing mischief. Early next week the technician and I plan to back up these keys, and then delete them.
Does anyone know what these keys are about?
(I found a blog that may be relevant: https://blogs.windows.com/windowsdeveloper/2017/04/13/com-server-ole-document-support-desktop-bridge/ But then again, it may not be.)
Keep in mind that older version of Windows Store Outlook ran in a sandbox and was not externally accessible. Uninstall it and reinstall again from the store - you will get a regular C2R version.
Eureka!!! Deleting those extra legacy Registry keys did the trick.
Computer\HKEY_CLASSES_ROOT\PackagedCom\ProgIdIndex\Outlook.Application
Computer\HKEY_CLASSES_ROOT\PackagedCom\ProgIdIndex\Outlook.Application\Microsoft.Office.Desktop.Outlook_16051.12325.20298.0_x86__8wekyb3d8bbwe
Computer\HKEY_CLASSES_ROOT\PackagedCom\ProgIdIndex\Outlook.Application.16
Computer\HKEY_CLASSES_ROOT\PackagedCom\ProgIdIndex\Outlook.Application.16\Microsoft.Office.Desktop.Outlook_16051.12325.20298.0_x86__8wekyb3d8bbwe
Our software immediately was able to create Outlook Application objects, and send email via Outlook.
It seems that these extra keys dated back to an earlier attempted install by the client (before their current technician became involved). There were about 20 or so other 'Outlook*' keys in that part of the Registry with '8wekyb3d8bbwe' in their name. I subsequently deleted these too - on the the assumption that they were all legacy garbage. (As a rule, it is pretty dangerous to delete things you don't understand - but so far, so good. Although I am too chicken to delete a host of others in that location for Access, Excel, PowerPoint, Word with with '8wekyb3d8bbwe' in their name too.)
I had the same problem; it came from a brand-new computer!
What worked for me was the early binding. Select: Tools > Reference > Microsoft Outlook 16 object library.
Dim objOL As Outlook.Application
Set objOL = New Outlook.Application
Set objOL = Nothing
At the end, setting objOL to Nothing is crucial, otherwise the instance stays open, and it causes problems with Outlook.
Reference.
I want to encrypt my email to prevent email forwarding. I try to enable Options > Encrypt > Connect to Rights Management Servers and get templates. But it is not functioning. No wait cursor, no any error message. And the email sent out still can be forwarded.
Anybody have same problem? Any idea?
BTW, I'm using Microsoft Office 365 ProPlus desktop version on windows 10.
It's working after few days later I check it again. Perhaps it is because of system restart. Don't know why. Anyway it works now.
Within our network infrastructure we utilize a 2007 Exchange Server for our domain.
Today I was faced with a situation where a user who has MS Office 2010 x64 and utilized Outlook 2010 called me and stated that her "Saved Items" inbox was missing. I remoted into her system and sure enough one of her mailboxes was not present.
It's easy enough to "fix" this by just adding the data file again which is located on a network share F:..\mailxxx.pst
This user has multiple mailboxes as a way to view her archived data.
Located in this shared folder there are additional .pst files that remained accessible to the user.
This appears to happen randomly and has happened at least one other time to this same user, and one time to a separate user who also has data on this same share.
Thoughts?
Microsoft does not support PST files on a network drive. This is a recipe for a disaster.
After the Open Directory crashed several times on a osx server 10.9 I decided to start from scratch; formatting the disk, installing osx 10.9 and setting up server.app as it was before.
To recover the mails I though being smart and copying the contents of the mailbox per user (Location /Library/Server/Mail/Data/mail/[OLD GUID]) to the fresh setup.
Logging in showed everything in the inbox. Now, few days later I find out that the sent folder is empty, or doenst contain any mails before the install. Turns out that only the inbox is copied.
Does someone has any suggestions how I can get back the sent items?
After some more research I solved my question; I hope that this helps my fellow colleagues in saving time and nightmares.
(Sub)Folders in dovecot have their own directory, starting with a dot (.), for example .Sent Messages. Because of that dot the folder is hidden. I copied the subfolders to the new mail directory, updated the correct user permissions and was able to get the old messages back.
If the user (or client software) already has added the same folder, simply rename it. Another possibility is to add a temporary user, restore the e-mails to that one. On the users mail client you add this temporary mailbox and move the messages to the correct folder. This last solution only works good when there are not too much messages.
What really helped me as well was connecting IMAP via the terminal using openssl, an easy guide can be found here.
I'm working on a .net project and interacting with outlook. The idea is that the user gets emails on his microsoft outlook client (outlook 2007 or outlook 2010). He chooses one of the emails and saves as Outlook Unicode message format (*.msg).
Then I took this file and read it by code.
The problem is that on certain machines, the file is saved with html tags, and in other machines the same email is saved without html tags and I use those tags to identify specific information of the email.
I've thought that it was a problem with the office or windows version, but don't, both machines has the same office version, the same windows version, and the same programs installed.
I have not been able to identify what is the difference between both machines. I'm sure it is related to unicode format or something.
NOTES:
The email format cannot be changed (no way, I've asked to the cliente).
The email contains tables inside it and the information I need is inside the tables.
I cannot do something different, so I need to have the client saving the email as explained before, and I have to process the email using a .net application created by me.
Does any body has any idea of what could be the problem here? I need to identify why both machine, with the same configuration, saves the same outlook email with different format.
I verify the email format opening it using notepad++
