Office 365 Backup
Iam Looking For: Find a backup solution for our Office 365 data such as SharePoint/OneDrive content, e-mails, calendars, contacts, notes, tasks etc. ! The harddrives of the machine definitly need to be encrypted. Not sure of synology can do that reliably (LUKS?). Synology had some security issues in the past, but they might have been only relevant if they are exposed to the internet. I think we have two options: Backup in the office on encrypted drives with very restricted access (SSH?) Encrypt backup and upload it to S3 (not sure if there's a tool for that) I'm fine with both. Is there an open source tool that can mirror Office 365 on a local machine? (Linux) is the Synology tool proprietary?Primer: Using Exchange Online PowerShell in Azure Automation Runbooks
In this Microsoft 365 automation primer, we cover how to create and execute Azure Automation Exchange Online runbooks (scripts) using cmdlets from the Exchange Online management module. Some setup is necessary before runbooks can process Exchange cmdlets, but once the necessary resources and permissions are in place, it’s all plain sailing. The next challenge is how to output data created in a runbook… https://office365itpros.com/2025/02/10/azure-automation-exchange-primer/HVE GA Update?
Hello! I had submitted a question on HVE (Azure Communications and HVE - Microsoft Q&A) and would like an update on its planned GA. Has a specific date been set for HVE to exit public preview and become generally available to organizations? We are excited to use HVE but prefer to wait for GA and understand potential costs before deciding. Thank you for your time.
Online Archive Not Working for One User
Hi, I am experiencing an issue with the online archive for one of my users. The online archive has been working correctly for this user for years, but it has not archived any emails for the past six months. I have checked the licensing, retention tags, and retention policy, and everything appears to be correctly configured. I have also tried running the Start-ManagedFolderAssistant cmdlet multiple times, but it has not resolved the issue. Other users in my organization have the same retention policy and their online archives are working correctly. I have also tried changing the retention policy for the affected user to one that is known to work for other users, but this did not resolve the issue. I have tried running several cmdlets to gather more information about the issue, including Get-Mailbox | FL RetentionPolicy, Export-MailboxDiagnosticLogs -Identity -ExtendedProperties, Get-RetentionPolicy | FL Name, Get-RetentionPolicyTag, Get-ComplianceTag, Get-Mailbox | fl *hold*, Get-MailboxStatistics | fl ManagedFolderAssistantLastRunTime, Get-Mailbox -Archive | fl *, and Get-MailboxFolderStatistics -Archive | fl *. However, none of these cmdlets have helped me identify the cause of the issue. The output from these cmdlets appears to be normal and does not indicate any issues with the mailbox or the archive mailbox. One thing I noticed is that the Get-MailboxStatistics | fl ManagedFolderAssistantLastRunTime cmdlet does not return any output for any of my users, even though I have run the Start-ManagedFolderAssistant cmdlet multiple times. I am at a loss as to what could be causing this issue and would appreciate any suggestions or guidance on how to troubleshoot it further. Thank you
Does Microsoft 365 business premium have unlimited online mail archive?
Does Microsoft 365 business premium have unlimited online mail archive? just want to verify ref: https://learn.microsoft.com/en-us/office365/servicedescriptions/exchange-online-archiving-service-description/exchange-online-archiving-service-descriptionAD Hybrid MailUser
I started a new job and noticed that the Exchange Online but the AD is hybrid and all the exchange attributes need to be managed in on-premises AD for proxyAddresses and Aliases. I didn't see an Exchange Server and was told it was uninstalled. How would I check that? I need to create a few MailUsers but the user accounts already exist. I have read that I should be able to Enable-Mailuser but that doesn't exist on Exchange online. How should I proceed in converting some Users to MailUsers without an exchange server on premise?
Incomplete SPF record for O365?
I've an odd email SPF issue. I'm receiving email from an organisation with O365 hosted mailboxes to an organisation not hosted in O365. The non-O365 organisation is correctly rejecting quite a lot of the O365 organisations email due to an SPF fail. The SPF record for the O365 organisation correctly references spf.protection.outlook.com but the emails being rejected are coming from Microsoft owned IP addresses that are outside the range of the addresses listed for spf.protection.outlook.com. The common theme is the SPF rejected emails all appear to be affecting O365 mailboxes that have an auto-forward to the non-O365 organisation. I initially thought it was an issue with Sender Rewriting Scheme, but the fact remains that email is coming from a Microsoft ip address outside the range defined by spf.protection.outlook.com. An example of one of the ip addresses that suffers the SPF fail is 40.95.64.60 (mail-vi1eur05rlyn2067.outbound.protection.outlook.com). Other email, not autoforwarded but just sent from the O365 organisation, is accepted as it is sent from MS ip addresses inside the range defined by spf.protection.outlook.com. From what I can tell, this means the O365 SPF range is not covering the full range of IP addresses that O365 sends email from, which ought to be corrected by Microsoft. Any thoughts welcome. Regards, V.Setup CatchAll-Mailbox for specific domain in Exchange
Hi, I want to introduce a CatchAll-Mailbox, meaning that all messages sent to non-existant recipients shall be redirected to a specific Mailbox. The basic idea is to introduce a rule that redirects all incoming messages and make an exception for recipients who are member of a Dynamic Group that contains all existing Mailboxes. To prevent exchange from instantly blocking the message and instead process the rules, i set the Accepted Domain to internal relay. Now i want to make this whole thing domain-specific, meaning it should only apply for unknown recipients of specificdomain.com. I tried to introduce a recipient-matches-pattern-condition but that didnt work. How can i set this up?
Trouble Sending to Gmail / Google Workspace domains
Hello, we have been having ongoing issues sending to gmail or Google workspace addresses for months now. I know that Google tightened up their requirement so domains had to have solid SPF, DKIM and DMARC setup, which we do and always have. We've worked around the issue all this time by using a connector and mail flow rule in Exchange online. This has worked OK, but every time we run into a new company we are dealing with that uses Google for email, we need to manually add them to the rule. This has lead to some problems and is disruptive and of course I fear that it may break at some point. We've registered our domain with the Google postmaster tools and it's verified there. We've opened tickets with Google months ago and get no response. Microsoft support tells us everything is fine on our end and it's Google's issue. This is the error we get: Error: 550 5.7.350 Remote server returned message detected as spam -> 550 5.7.1 [2a01:111:f403:2412::72e 19] Gmail has detected that this message;is likely suspicious due to the very low reputation of the sending;domain. To best protect our users from spam, the message has been;blocked. For more information, go to; https://support.google.com/mail/answer/188131 98e67ed59e1d1-2e059080a69si2208538a91.116 - gsmtp Message rejected by: mx.google.com There is no spamming or anything coming out of our domain and we have a very small volume of email. Online checks of our domain don't show any reputation issues or blacklists. I've seen I think dozens of other people complaining about this issue, but don't really see any actual solution other than the email connector workaround. Anyone have any suggestions? Thanks!
