Outlook (New) redicts to Microsoft Edge to access emails
After the recent 365 apps, a few users in our organization are experiencing an issue with accessing emails on the Microsoft Outlook (New). When we click on the Outook(New) icon and it opens and redirects to Edge window to access emails. I tried several troubleshooting steps to resolve this issue and submitted a case with Microsoft Support but not helpful so far. Anyone else experiencing the same problem ? Any suggestions or fix will be greatly appreciated. ThanksChanging the Offline Access Period for Sensitivity Labels
One of the settings for sensitivity labels governs how long items protected by a label remain accessible (including offline access) before reauthentication. The default is 30 days, which is a good balance between security and avoiding users having to constantly reauthenticate to open protected messages and files. If necessary, tenant administrators can change the validity period to be anything from 0 to 65535 days. https://office365itpros.com/2025/10/14/offline-access-validity-period/External people can't open files with Sensitivity Label encryption.
Question: What are the best practices for ensuring external users can open files encrypted with Sensitivity Labels? Hi all. I've been investigating proper setup of sensitivity labels in Purview, and the impact on user experience. The prerequisites are simple enough, creating and configuring the labels reasonably straightforward, and publishing them is a breeze. But using them appears to be a different matter! Everything is fine for labels that don't apply encryption (control access) or when used internally. However, the problems come when labels do apply encryption and information is sent externally. The result is that we apply a label to a document, attach that document to an email, and send it externally - and the recipient says they can't open it and they get an error that their email address is not in our directory. This is because due to the encryption, the external user needs to authenticate back to our tenant, and if they're not in our tenant they obviously can't do this so the files won't open. So, back to the question above. What's the easiest / most secure / best way to add any user we might share encrypted content with to our tenant. As I see it we have the following options: Users have to request Admins add the user as a Guest in our tenant before they send the content. Let's face it, they'll not do this and/or get frustrated. Users share encrypted content directly from SharePoint / OneDrive, rather than attaching it to emails (as that would automatically add the external person as a Guest in the tenant). This will be fine in some circumstances, but won't always be appropriate (when you want to send them a point-in-time version of a doc). With good SharePoint setup, site Owners would also have to approve the share before it gets sent which could delay things. Admins add all possible domains that encrypted content might be shared with to Entra B2B Direct Connect (so the external recipient doesn't have to be our tenant). This may not be practical as you often don't know who you'll need to share with and we work with hundreds of organisations. The bigger gotcha is that the external organisation would also have to configure Entra B2B Direct Connect. Admins default Entra B2B Direct Connect to 'Allow All'. This opens up a significant attack surface and also still requires any external organisation to configure Entra B2B Direct Connect as well. I really want to make this work, but it need to be as simple as possible for the end users sharing sensitive or confidential content. And all of the above options seem to have significant down-sides. I'm really hoping someone who uses Sensitivity Labels on a day-to-day basis can provide some help or advice to share their experiences. Thanks, Oz.Creating a Comprehensive Inactive Guest Account Report
Many examples of how to report inactive Entra ID guest accounts with PowerShell are available on the internet, but they're all flawed because they make decisions based on the last sign in. That's a shortsighted method because it doesn't take guest activity into account. This article explains how to combine audit data with sign-in data to create an enhanced view of guest account activity so that intelligent decisions can be made to keep or retain the accounts. https://practical365.com/inactive-guest-account-report/Replying to emails from M365 Outlook group
A problem I am stumped with, so I am reaching out for some help/guidance. One group wants to not have the emails going into their own inbox but manage and reply only from the group inbox itself (so they know the email has been processed by deleting it once replied). It worked OK to begin with and then some users couldn't reply, then more. Some still can. I have tried reindexing local copy, using browser instead of app & changing the send on behalf of permissions. Owner or member of group doesn't seem to make a difference. Error messages include "This message can't be sent because it no longer exists. It can only be discarded. Make sure you copy the contents of the message before you discard if you want to use them later." and "Couldn't send this message". Please see screenshots attached. My questions: 1: Is Outlook on M365 designed to allow users to reply from the group either as the "group" or as themselves? Information I found isn't clear. 2: If it is / can be - what can I do to make it work for all users? Thanks!ChatGPT Enterprise Connects to SharePoint Online
OpenAI has launched a ChatGPT enterprise SharePoint Connector that allows organizations to synchronize files from SharePoint Online to ChatGPT. I could never understand why Microsoft 365 tenants allowed users to upload individual files from SharePoint or OneDrive to ChatGPT for processing. Using a connector to synchronize entire sites to ChatGPT makes even less sense, especially from a compliance perspective. I must be missing something! https://office365itpros.com/2025/10/13/sharepoint-connector-chatgpt/
Formula not working - Dynamic array for subtraction
Currently I'm facing a error with the below formulas, which is giving Error "You have entered too many Argument for this function" or simply "Zero" is coming as output. Hence requesting any SME support to fix this formula and help me to make use in my spreadsheet. Below few trouble shoots done from my end before publish my concern here: 1. I have ensured there is no blank cells or without values. 2. I'm using MS-excel 365. where few functions in the formula is compatible for my version as mentioned on the internet. Formula 1: =IF(COUNTA(BD3:BO3)<1, "", IF(LOOKUP(2,1/(BD3:BO3<>""), BD3:BO3) = LOOKUP(2,1/(BD3:BO3<>""), OFFSET(BD3:BO3, 0, -1)), LOOKUP(2,1/(BD3:BO3<>""), BD3:BO3), INDEX(BD3:BO3, 1) - SUM(FILTER(BD3:BO3, (BD3:BO3<>"") * (BD3:BO3<>OFFSET(BD3:BO3, 0, -1))))) ) Formula 2: =IF(COUNTA(BD3:BO3)<1, "", LET( LastValue, LOOKUP(2, 1/(BD3:BO3<>""), BD3:BO3), PreviousValue, LOOKUP(2, 1/(BD3:BO3<>""), OFFSET(BD3:BO3, 0, -1)), IF(LastValue = PreviousValue, LastValue, PreviousValue - LastValue) ) ) Formula Purpose Intended: To dynamically subtract the values from left to right on the last 2 non-empty cells from the given range BD3:BO3 1. Running Subtraction: Subtract values of last 2 non-empty - Last non-empty cell from the above specified range, it should subtract the last 2 non-empty cell only, whenever the range sequentially get updated with values. 2. Ignore Duplicates: If the value being a duplicate/same in the last 2 non-empty cell, then the subtraction operation should be skipped & the formula should only give the same value in the last non-empty cell. Please help me to fix this, I have tried multiple measures but still the error persist . I have attached sheet as well.
File string limit check
Is there a report that can be run on Sharepoint to show file string size sorted highest to lowest? The issue we are running into is the difference between Sharepoint character limit and Windows Character limit. Out of the box they are different and Sharepoint's string limit is considerably higher. If there was a report, we could get a head of syncing issues.
Can't Install 365 on Mac Air Sequoia 15.7.1
I have a 2024 Mac Air with the latest Sequoia OS, 15.7.1. I am looking to replace MS Office Version 16.101 with MS 365. I have uninstalled 16.101 three times and then tried to install from the online MS 365 site three times, and each time I end up with the old Office 16.101, not 365. I have spent endless hours online and by phone with MS bots and personnel, and with the JustAsk technical "service" they referred me to (which was a waste of $45). No one has an explanation and they just keep telling me to uninstall and reinstall. There seems to be some technical incompatibility between 365 and my Mac, so when I go to download it feeds me 16.101 without explaining what that incompatibility might be. I'm not a techhead, but I have used Mac Airs for years and MS for decades without such problems. Has anyone else had such problems? Any suggestions? Thanks for any help.
