Disable automatic updating of email addresses exchange 2016
• Open System Preferences • Open Internet Accounts • Select your Exchange Account • Turn Off Contacts for Exchange You should now see those automatic generated contacts gone. Everyone is so fond of saying that this doesn't happen, but it's happening to me as well.
It's been happening for months now, and I first noticed it when I was on Mavericks. Office 365 and Exchange accounts have a "Suggested Contacts" feature that has caused this problem for me.
Each mail user has an external email address and the emais sent to the mail user is routed to this external email address.
This issue was driving me nuts, but I just tried it. Whenever I send a message using the OS X Mail app, I suddenly find that same e-mail address in my contacts.
There are several thousand email contacts that reside under the Federation_Contacts OU.
So I wrote a script based on the one provided in question (the one in question had some bugs where multiple addresses from same domain were assigned and it was making a lot of noise) that will remove any email addresses that are not external and it will also make sure the old contacts won't get policies reapplied. C:\Windows\System32\Windows Power Shell\v1.0\-command ". 'C:\Program Files\Microsoft\Exchange Server\V14\bin\Remote Exchange.ps1'; Connect-Exchange Server -auto; C:\Exchange Script\Remove LGBSEmails From Contacts.ps1" First of try to identify the policy that might be the one samping these addresses. To clean up the mess powershell is there for you if you need to do bulk changes.Thus in my case, this is a Microsoft problem, rather than an Apple problem.That may be why so many answers to this question are, "Mavericks/Yosemite does not do this". Everyone is so fond of saying that this doesn't happen, but it's happening to me as well.When creating a new migration or backup job, you specify which mailboxes you want to migrate or back up by their primary SMTP address, shown in the software. Providing the target mailbox address manually in Code Two Exchange Migration.The above error shows up when you change this address on the target server while the migration or backup process is already running. The primary SMTP address may change automatically when you implement a new Email Address Policy or change the domain name.
