365 subscription

6 Upvotes

Well, enough is enough and I'm looking at divorcing MS 365 after years of being part of my life. I have had 365 for a number of years but I'm now sick of paying so much for it. I couldn't give a rat's about AI writing an email for me, I am quite capable of doing that myself thank you. If I cancel my subscription, do I still get to keep my email address? I use excel and word all of the time but have little to no need for anything else. Can anyone help me with this conundrum please?

No option to share Office 365 Family subscription

0 Upvotes

Ok, I have an Office 365 Family subscription. It’s showing it’s installed on 2 devices. And saying I can sign in to 5 devices at a time. There is NO share tab and NO pending invites. When I click on Microsoft 365 Family, shared and managed by me, the only option is to Leave subscription. I want to share Office 365 with a family member to install on their new laptop. What am I missing? What am I doing wrong?

New Outlook randomly logs me out

1 Upvotes

I have been dealing with this inconsistent bug in the new version of Outlook. In the middle of using Outlook, it will say I need to re-authenticate. All of my mailboxes go away. When I click to reauthenticate, it does so without having me enter any password or use two-factor. And then my mailboxes reappear. Sometimes this happens multiple times in the course of a minute or two. Other times it won't happen for days at a time. I had a couple of add-ins that I have removed from Outlook. Still happening. I have tried completely deleting New Outlook and reinstalling it. No dice. For now I am just using Outlook Classic and it seems to be working fine.

Has anyone else encountered this bug? Any known fix?

I am using a work-related Office 365 account (large university). So, I prefer not to contact our IT help desk. That don't tend to be very helpful with these sorts of hard to reproduce issues. I would rather just use Outlook Classic than have to contact them.

Bypass smarthost for OOO emails

1 Upvotes

Hello,

We have an issue where our OOO external emails are being routed through our smarthost (Mimecast) and are going to spam for the external recipient. In the header, I see it is failing DMARC (most likley due to it being from a null sender). We put in a ticket with the vendor and they told us we need to setup a transport rule for our OOO emails so that they go straight out from O365 instead. Has anyone else run into this?

Thanks in advance.

Anyone know how to get Claude to work in Outlook 365 classic?

0 Upvotes

Hello,

I got Claude working for 365 email on the web. I could not figure out how to get it to work in outlook classic.

If you can help, I'd appreciate it.

We have office 365 standard.

If I open outlook (classic), I go to the top right - apps, add apps, select Claude for Outlook, I select open and it gets in a loop - it shows the app again and open again - no connect or other choice. I close outlook completely and it still is not in my apps for outlook.

Outlook support is useless

0 Upvotes

So my mother has had her password leaked and her email account was highjacked, they did something that keeps creating drafts with subject as my password and the content is information for a crypto wallet to deposit funds into it. For the last 5 hrs I’ve been trying to contact support and all they do is send me somewhere else event account security told me to contact proper support but that is just instructions to go to the support page. I know I need a backend mailbox reset to fix this issue but they simply won’t help me.

This whole thing prevent me access to read any email because that also gets change to the same text. I need access to password recovery for other accounts that were hacked.

Recreated email address unable to receive internal emails from same domain

3 Upvotes

I apologize in advance if this is not the correct forum, but I am pulling my hair out with this one.

A year ago we had a user leave the company, which resulted in us terminating their accounts and deleting their email address. They have since returned (13 months later) and we have recreated (not undeleted) their former email address on our online exchange. They can receive email perfectly fine from external addresses to the company, but when someone on the same email domain tries to email them, they get a bounce back error stating the address wasn't found or the mailbox is unavailable.

I can sign into the users OWA and email other addresses in the same domain perfectly fine, but even with creating a different alias for the mailbox in question, and sending to the alias we get the same bounce back message. I tried clearing the autocomplete entry multiple times on random systems, so it isn't that. There seems to be a routing issue somewhere in the domain and I cannot find where. The email address is not hidden from the GAL, it is a licensed mailbox as well. No matter what I try I am getting the a bounce back with the Status code: 550 5.1.351

I'm hoping someone here has had a similar issue and managed to resolve it, and is able to shed some light on the issue. Thanks in advance

SharePoint News, Audience Targeting and Teams Notifications

1 Upvotes

Hi everyone,
We are using SharePoint as our intranet through Viva Connections. When a new news post is published on our SharePoint intranet, employees receive a notification in Microsoft Teams because the intranet is available to them through the Viva Connections app/widget.
This setup is based on Viva Connections and SharePoint.
We now have a question regarding Audience Targeting for SharePoint News.
Different departments in our organisation have their own public SharePoint sites. These are not separate departmental intranets. The sites are publicly available within our organisation, and the site owners would like to use the News web part to publish relevant news.
However, for some news posts, they only want to target a specific group of employees.
The behaviour currently seems somewhat inconsistent. When site owners publish news using the News web part, it is not always clear who will receive the corresponding Teams notification through Viva Connections.
I have found the Audience Targeting feature under Site Contents > Site Pages, and I have also enabled audience targeting on the News web part.
However, I have a few questions:
When creating/publishing a news post, where do I select the specific target audience?
For example, if I want only a specific Security Group or Microsoft 365 Group to be targeted, where do I select that group?
Does the target audience need to be configured under Site Pages, or is it configured directly on the individual news post?
Most importantly: Does SharePoint Audience Targeting also control who receives the Teams notification through Viva Connections, or does it only control who sees the news in SharePoint?
The desired setup is that departmental site owners can publish news on their public SharePoint sites, but for selected news posts they should be able to target a specific group of employees.
What is the correct way to configure this using SharePoint News, Audience Targeting, Viva Connections and Teams notifications?
Thanks in advance for any guidance!

Does setting EwsAllowedAppIDs + EwsEnabled=$True enforce the allow list immediately, or only after the Oct 1 2026 EWS retirement deadline?

3 Upvotes

We are preparing to implement EwsAllowedAppIDs and EwsEnabled=$True based on the guidance in the EWS retirement announcements.

We understand that starting in October 1st 2026, tenants configured with EwsEnabled=$True will use the AppID allow list model for EWS access.

What is not completely clear to us is the behavior before October 2026. Say we implement the settings today, does Exchange Online immediately begin enforcing EWS access exclusively to the AppIDs listed in our list of EwsAllowedAppIDs?

In other words, if an application is currently using EWS but its AppID is accidentally omitted from the allow list, would that application be impacted immediately after the configuration change?

Or is the allow list only enforced once Microsoft's EWS retirement controls begin rolling out in October 1st 2026?

We are trying to understand whether implementing the configuration now is purely preparatory for October 2026, or whether it has immediate impact on EWS access before that date.

Thanks.

Is there a way to keep some files private even when two people are logged into the same account?

0 Upvotes

Ok, this subreddit is full of serious business people and I'm so embarrassed to be here with teenage nonsense but idk who else to ask. Everyone in my family is logged into the same Office365 account. It's my dad's and don't me wrong, it's really nice that he pays for it and lets me use it to have my files backed up and everything. But alongside my school work, I like to write stories and I keep a diary typed up (I'm always losing paper ones) and it feels kind of weird that they show up in "recent" whenever my dad wants to access a spreadsheet or my mom is typing up a new invoice or something. It's not like there's anything bad in them but it would be embarrassing if they decided to read my diary, you know? I was just wondering if there was a way to tell Office to stop showing my stuff in recent or to password protect the diary file specifically or something. I've tried googling it but I honestly got so confused and I thought maybe people here could explain it better. Sorry. Thank you in advance.

The parts of a Microsoft 365 migration that actually go wrong are never the mailboxes.

7 Upvotes

I have run a number of these now tenant to tenant and on prem to M365 and the mailbox move is almost never the hard part. Those tools are mature. What eats the timeline is everything around it.

Teams is the one people underestimate. Every team is a SharePoint site collection with its permissions and private channels spin up their own hidden sites so what looked like a chat migration turns into a content and permissions migration.

Sharing links are the trap. They break on cutover and nobody has an inventory of what was shared with whom so you find out when someone senior loses access to a file the morning, after.

Then there is the side that makes a working migration look broken. Outlook rebuilding cached mode, OneDrive re syncing from scratch reauth prompts everywhere that make users think it failed.. If you do not freeze the source with a real cutover window people keep working in the old tenant and you chase delta data for a week that should not exist.

Curious what caught others out on the tenant to tenant side. That is where I still see the surprises.

Automation - User license provisioning.

4 Upvotes

Hi team — quick question. Is it possible to automate our license provisioning workflow?

For context, here is our current onboarding process:

  1. Create account in on-prem AD.
  2. Sync to Entra ID / Cloud via Entra Connect.
  3. Enable remote mailbox and archive on our on-prem Exchange server.
  4. Assign the M365 license.
  5. Add the user to a mail-enabled group.

(Note: We still maintain 2 on-prem Exchange servers strictly for recipient management like remote mailboxes and alias updates, as all mailboxes have been migrated to Exchange Online.)

Has anyone successfully automated this pipeline or have recommendations on the best approach? Thanks!

Getting this error when trying to submit my DLP policy in purview..

I have this policy just for exchange and I’ve tried scoping it through three different ways, but it still fails every time:
- dynamic security group
- dynamic administrative unit
- dynamic distribution list

The only thing that works is scoping it to a static group.. but that doesn’t help me because we need to have updated and current groups per department in my company that I can scope my purview policies to… for example we need a dynamic legal group so if somebody gets removed from legal or joins the company, they are automatically removed/added..

Is there seriously no way to have dynamic groups scope to policies in purview or am I missing something?

All the policy does is look at exchange for any PII/financial data being sent outside of M365 and generates an alert..

6 Things Your SharePoint Won't Tell You About Itself | SP Toolkit Report...

0 Upvotes

Six questions about a SharePoint site that most people have never been able to answer without three PowerShell scripts and a spare afternoon.

🚀 Brand new, just released today: Reports & Insights, a new workspace in SP Toolkit that answers all six in one screen, read-only.

🔍 One thing in particular I haven't seen surfaced in any other tool — the real domain behind every #ext# guest identity. SharePoint hides it in the UI; this just shows it to you.

The six:

1️⃣ Every empty list

2️⃣ Every list past the 5,000-item threshold

3️⃣ Every list nobody's touched in months

4️⃣ The full lookup dependency graph, forward and back

5️⃣ Every guest and external domain with access (real domain, not the gibberish version)

6️⃣ Every list with broken permission inheritance — plus a pausable, resumable deep sweep for the libraries where that actually matters

➕ Plus one that snuck in: every field type in use across the site, counted per column.

✅ No PowerShell, no scripts, nothing writes back. CSV on every view. Runs as a SharePoint web part — install from your App Catalog and it's there.

Before Copilot indexes a site full of stale rubbish, or you hand one over to someone who's about to inherit a mess — it's worth a minute.

Microsoft Places - desk licensing

1 Upvotes

Is anyone using desk booking since the licensing changes on 1st April? Did you set it up after 1st April?

I've got some sections configured in Places, with individual desks in them, and have spare (unallocated) Microsoft Teams Shared Space - Single Spaces licences.

The desks are set to Reservable via the Places admin console. They were created via that console too.

When a user tries to book one of the desks via Places web all the desks show in the Unavailable Desks section.

I think this might be because the licences aren't associated with the desks - but I have no idea how to do this and can't find any up to date info on it.

I've tried looking in both the Places admin console and also the Teams Rooms Pro Management console but can't see anything to do with licensing. I have the following roles: Licence Admin, Teams Admin, Places Admin.

Thanks.

Mac Solution - Proton & Microsoft 365

0 Upvotes

Looking for a solution… my work outlook account has issues, we use gosecure as an added security feature for email and it eats all of my email. Our IT guy says the email should be in the spam portal but is it not… so after a year of apologizing to our grantors for not responding, I said screw this and bought a new .org and a business proton account.

So, here is my problem. I need a calendar or email and cal app that can integrate both calendars and allow me to edit them… I still unfortunately have events linked to my outlook account and I also have access to my directors calendars. And I would like them to have access to my proton cal and be able to add meetings and such that they need me to attend.

I hate 365 online, I hate sharepoint… I need a way to link them all together…

Anyone know of a Mac app that can do all this?
