Office 365 is a group of software plus services subscriptions that provides productivity software and related services to its subscribers. Office 365 allows the use of Microsoft Office apps on Windows and OS X, provides storage space on Microsoft's cloud storage service OneDrive, and grants 60 Skype minutes per month. Office 365 includes e-mail and social networking services through hosted versions of Exchange Server, Skype for Business Server, SharePoint and Office Online, integration with Yammer, as well as access to the Office software. All of Office 365's components can be managed and configured through an online portal; users can be added manually, imported from a CSV file, or Office 365 can be set up for single sign-on with a local Active Directory using Active Directory Federation Services.

Hi Experts,

I have a problem with one outlook client.
The clients said he has not send this emails.

We use Exchange Online and O365.

I've had a request from a client which I thought would be simple however it is turning in to a nightmare.

It is to share calendar free/busy between two Office 365 tenants.

As a proof of concept I've added both domains in each others tenant and the Organization Sharing now shows my two 'federated' Exchange organizations listed.

However calendar information is still not showing between any users cross-tenant.

One of the clients is a hybrid environment with existing on-prem Exchange and one is cloud only.

I've also added each of the Domains in to the Default Sharing Policy in case this was being caused by calendar permissions.

I'm a bit stumped as what is causing this to fail and Microsoft do not seem to have much information on this except how to configure which is already done. I've seen blog posts where people have configured it in the same way as me and it is working.

One thought that I did have was; is any of this affected by conditional access as one of the clients have strict conditional access, but without knowing for sure I do not want to really touch these.

Thanks

I'm having an issue that I cannot seem to get through. There is email from one external sender that just seems to never make it though to our user's inbox. We have a barracuda firewall for email and it shows as passing through and being delivered. In ECP, I've done a message trace and it shows that the email was delivered to the user's inbox. I have thoroughly scoured the account and there is no email from the sender, not in inbox, junk, deleted, etc.

I've done everything I know to do at this point, any help would be appreciated.

We have all users enabled with the E5 but have the exchange license off.  We basically need to run a script against a group that turns that exchange license on under the E5 once the person is migrated to Office 365.  can someone provide a way to do this in Powershell with Office 365?

I am curious if we could use a distribution list as a login to team so that we can notify other users not in the distribution list in the teams chat feature.

Currently the only way I can see this happening if the email address is a unique address.

Hello,

We are using O365 with Office 365 Pro Plus.

There are times when some of our users need to include sensitive PII information in their emails to outside parties.  

What is the best way to secure those emails?  

Please advise.  

Thanks.

There are plenty of items on the internet about how to set versioning for my OneDrive users, however, the settings for this are no longer available to my users.  I did see that Microsoft made a change to that policy... and is no longer available for users.  What are my options to set versioning parameters? Instead of 250 versions default i'd like to make that number much lower... corporately if i can... to say 10 last versions.

Hello experts. I created a test pdf form in Adobe Acrobat Pro with three simple text field properties. Test1, Test2, and Test3. I have a table in ms access for office 365 call tbl_test that contains the identical field names as my pdf names. Test1, Test2 and Test3.

All I am trying to do is populate the pdf form field names with what every I put in my ms access field names. Everything I have tried to google or go on youtube (preferably since I am not a programmer) to view shows how to export from say an entire excel into a pdf to where I am looking for say some sort of mapping. Hope I am making sense and any help for a newbie would be great.

Hello all.

I am experiencing an issue with a critical user who is currently in an ongoing litigation from 2013.   Currently his O365 sent folder only is showing emails from 2015 on.   He needs to be able to locate emails prior to 2015.   When the original migration was done from their old exchange environment to O365 by default we took everything that was in the onprem exchange and sucked it into O365.   However a year later we are being told there was more mail then what is currently listed.   I found a link on Microsofts retention policy

https://docs.microsoft.com/en-us/exchange/security-and-compliance/messaging-records-management/default-retention-policy

This is a very confusing article.   Because of O365 default retention policy that we are unable to get mail before 2015.   Has anyone run across this?  This is critical that they are able to retrieve sent messages prior.   If he logs into portal.office.com the mail only goes back to 2015 so policy somehow kicked in I think when the migration was done and only did 5 years worth.   But I have a feeling when the migration took place there was more than 5 years, so I am hoping perhaps email is sitting somewhere in MS cloud and can be retrieved prior to 2015.   As always appreciate the help.

P.S. I am reading that after the retention policy date is exceeded email goes into an archive.   Is this retrievable?

Hi:

For the first time in almost a year of using Office 365, Outlook just today started giving me an error upon trying to open Word document attachments.

It gives me that error message saying that Word experienced an error trying to open the file.

This error even appears if I save the attachment on my desktop and try to open it.

I tried several suggestions that I found online, but none of them work.

And, this issue only occurs with Outlook Desktop - not Web Outlook.

Please let me know how to eliminate this issue.

Thank you!  Much appreciated!

I configured the mail forwarding hook inside the office 365 admin console to flow to a different mailbox. How can I setup this user when getting the forwarded mail comes over that it can go right into a separate folder?

I am assuming it needs a separate folder and a rule for the targets inbox correct?

Has anyone seen or noticed iPhone users that run the Outlook app for their O365 account that have shared mailboxes simply disappear out of the clear blue?   One of my users just called in and states both of his shared mailboxes were gone out of his outlook but his primary account was still there.  He swears he didn't delete them manually because it would have meant he would have physically had to have removed both, however he claims they just disappeared.   I walked him through re-adding them both and they appeared.   Figured I'd ask.

We successfully completed a cut-over migration from Exchange 2010 to O365.  We utilized the Azure AD Sync Tool to populate all the users and sync all the mail.  The migration actually completed the first week of January.  I've left the exchange server up and running just in case something went wrong this whole time.  

On February 3rd, I disabled the Azure AD sync with O365, so now all mailboxes Sync Status shows the "Cloud" instead of "Sync with AD".  I left the Azure AD Connect Tool installed on one of our DC, and will remove it in the near future.

On February 6th, I powered down our Exchange 2010 server and then powered it back up yesterday, February 13th.  I just wanted to make sure any mail related services were not pointing to the Exchange 2010 server.  One week with the server off-line should be sufficient for this need.

Now I want to start removing the Exchange 2010 completely.  All O365 mailbox management will be done in the O365 console. and I simply do not want to have any exchange services within our local network.  I want to properly remove the exchange server so that all the Exchange AD attributes are properly removed in case we decide to install another on-prem exchange server in the future.  

I first want to know if I need to remove all the mailboxes before removing mailbox databases, etc.  I am using the following article to assist me remove Exchange:

Have a customer that switched to Office 365 Business Premium. They were using the default MAIL app on iPhone to send and receive emails. Now they are using Outlook APP to sync with Office 365 and Outlook Desktop. They were using POP before on both accounts with WIX EMAIL HOSTING (account dead now) and have some SENT emails that are currently still in the default MAIL app on iPhone. How can I get all of those SENT ITEMS in the dafualt MAIL app on Iphone into the SENT ITEMS of OUTLOOK on Desktop?

I have iCloud app installed on the Windows Laptop and it appears to be syncing the CONTACTS and the CALENDARS, but I see NO EMAIL.

TL;DR
Need to get SENT EMAIL from Apple default MAIL app transferred to Outlook DESKTOP SENT ITEMS.

Thanks

Please help me to find the right solution to the issue we've got.

Our Infrastructure details: ADFS 2016, Most of our mailboxes migrated to O365, On-prem Exchange and SFB still in place.
(A)  We've implemented ADFS Okta adapter for MFA.
In fact, it is a .NET app which appears on the ADFS landing page as an embedded small window after provided credentials, whenever a user should be challenged for the second factor.
(B)  We've enabled Modern Authentification on o365 tenant (was turned off).
(C)  We've created GPO for ADAL (enable) for Outlook 2013, 2016, Lync.

On ADFS created an Access Control Policy for a Group of users - "require multifactor" when on the external network, applied for "MS Office Identity Platform" Relying Party Trust

All BROWSER O365 ONLINE experiences on all devices (mobile included) and OSs is excellent, going through the following steps:

1. Office.com
2. AutoDetect
3. Company's ADFS
4. Password provided to ADFS
5. Okta adapter prompts for the second factor (embedded into the ADFS view)
6. Second-factor confirmation received, access granted

(MFA enabled users on domain-joined workstations were not able to use it at all, even on the internal network) experiencing continues prompts for credentials and autodiscover change.
To fix Rich clients connection issues were undertaken steps (B),(C) mentioned above. After that, all the clients on the internal network just connected to exchange without additional steps.
Now we have…

switched to office 365 and now I keep getting prompted for a password to connect to my exchange server.
I tried going to credential manager and deleting the entry, and have verified that autodiscover can be resolved by nslookup and is working properly.
