Had a ticket regarding 3 different sent emails to 3 different third parties which were getting duplicated into an IT mailbox on Office 365.
I double checked the “rules” under Mail flow to make sure there were no BCC rules for the users sending which there were not.
In MailTrace the emails came up as Status “Expanded”. This means the email has been sent to a group, however the original email was sent to a Single External Email address?
Why was the external email being displayed as a group in 365?
Turns Out the Outbound Spam Preferences had been turned on! And for whatever reason, these items were triggering the BCC of suspicious messages!
On Upgrading from Office 2013 to Office 2016 ( Must be 32 bit ) the following error displayed
You need to download this script and run from a Command Prompt which has been run as administrator
If you get an error about not being able to read the Key : HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\ConsentPromptBehaviorAdmin
It means the User or CMD window does not have enough permissions
Recently had a user with a new Office 365 account receive the above error during downloading new email. Testing the connection it looks like the Wireless connection she was connecting to the internet with was intermittently slow.
Changing the Wifi to a hotspot or cable connection resolved this
Previously, we used a development instance of Azure AD Connect with a development Azure AD tenant to investigate the rules. However, Microsoft has created new functionality in the adfshelp.microsoft.com ADFSHelp Portal:
In the Tools section, there is now a Claims Generator wizard labeled Azure AD RPT Claim Rules, that will help you get optimized claims rules for the ‘Office 365 Identity Platform’ RPT.
Can be done via IMAP Settings below
Settings for IMAP Configuration:
EMAIL ADDRESS: sharedmailbox@domain.com (shared mailbox)
IMAP SERVER: outlook.office365.com Port 993 with SSL
SMTP SERVER: smtp.office365.com Port 587 with TLS
USERNAME: user@domain.com\sharedmailboxalias (user\shared mailbox alias)
PASSWORD: UserPassword (user’s password)
SMTP LOGIN IS DIFFERENT (!)
USERNAME: user@domain.com (users email)
PASSWORD: UserPassword (user’s password)
Recently had a client with Office 365 trying to Cache a Shared Mailbox. Outlook brought up a load of Sync Errors
Your server administrator has limited the number of items you can open simultaneously. Try closing messages you have opened or removing attachments and images from unsent messages you are composing.
If the server is self hosted you can remove the restriction via : http://henrysluiman.blogspot.com.au/2013/02/how-to-increase-number-of-open-items.html
Microsoft fix for this is removed the Cache! https://support.microsoft.com/en-us/help/3115602/performance-problems-when-you-try-to-access-folders-in-a-secondary-mai
After rebuilding the OST and Profile and still no luck I started Outlook in Safemode which enabled the downloading of the emails
Once downloaded I could start Outlook Normally and all worked fine
There are three ways to forward mail from one user to another in Exchange
1 and 3 can be checked easily and there will be references of when this is done and not done usually in tickets , however users can enable Inbox rules by themselves then contact your later to disable the forward.
Here is how to check for forwarding or redirecting rules on mailbox in 365
foreach ($i in (Get-Mailbox -identity %USERNAME%))
{ Get-InboxRule -Mailbox $i.DistinguishedName | where {$_.ForwardTo} | fl MailboxOwnerID,Name,ForwardTo }
foreach ($i in (Get-Mailbox -identity %USERNAME%))
{ Get-InboxRule -Mailbox $i.DistinguishedName | where {$_.ReDirectTo} | fl MailboxOwnerID,Name,RedirectTo}
To Disable
Disable-InboxRule -Identity "%NAME OF RULE%" -Mailbox "%USERNAME"
When clicking on the down arrow in Office 365 to change Reply to all to Reply , for some reason the menu showed at the top of the browser
Clearing Cache did not fix this or Zoom size
Reset Chrome to default settings ( which still keeps Favorite bookmarks but clears plugins ) fixed this
Recently after setting an Office 365 Mailbox user up via Windows Live as they did not have Microsoft Outlook installed and didn’t want to use Webmail
You need to use IMAP settings for this as there is no Active Sync connector
After setting up Windows Live , a test email to the user’s self from himself never reached the Inbox after it was sent. If I sent one from Webmail it would come through
After research , it turns out it was going into Junk Email in Office 365 after being sent from smtp.office365.com on port 587 and this folder was not syncronised in the Windows Live settings so did not show.
I had to disable the junk mail filter or add a rule which would whitelist the own user from Junk Mail!
